Uncle Mike’s Guide to Tomato Patio Gardening

There’s nothing like harvesting your own fresh tomatoes! Even if you don’t have a lot of space, you can still enjoy this delicious summer staple by growing tomatoes in containers.

Important tips for your patio tomato garden:

  • When choosing your container, bigger is always better. The larger the container the better the plant and harvest will be. You’ll also see fewer problems with blossom end rot, lack of water, and overall health from lack of nutrients because more soil will hold more nutrients and water.

 

  • When choosing your tomato varieties bigger is NOT always better. Try to grow the medium to small size tomatoes instead of the large ones. Large tomato varieties like big boy or beefsteak are less forgiving with lack of water.

 

  • Always fertilize. Plants in containers use up nutrients more quickly and you’ll need to replace these nutrients by using fertilizer. Uncle Mike plants his tomatoes with an organic granular fertilizer like Espoma Tomato-Tone and adds Neptune’s Harvest throughout the season with every other watering.

 

 

  • Tomatoes grown in containers tend to be more susceptible to blossom end rot. Many people don’t realize that blossom end rot is a calcium deficiency not a disease and the cure is calcium, not a fungicide. This makes fertilizing even more important as a preventative step. You could also try adding Espoma Organic Garden Lime or MagiCal for extra calcium. Remember, prevention is better than a cure. It’s best to keep this fertilizer and/or calcium in the soil before you have a problem because if your plants do develop blossom end rot the fruit should picked off and discarded. Don’t wait to feed!

 

  • Use the proper soil. A typical soilless potting mix could dry out too fast for your tomatoes. Add a little compost to a regular potting mix or use a raised bed mix like Castline Raised Bed Mix or Organic Raised Bed Mix.

 

Uncle Mike’s Favorite Tomato Varieties for Containers:

Patio

Not a generic term but a variety. A dwarf plant with medium size fruit. Great for containers 10 inches in diameter or larger.

Better Bush

A good dwarf plant with small to medium fruit. Plant in containers that are 10 inches or larger.

Moby Grape

This grape is a determinate variety so the plant won’t get too big and it’s everything you will expect from a sweet grape tomato. Plant in a 10 inch container or larger.

Totem

This is another dwarf plant that stands somewhat vertical and not too wide. The fruit is delicious. Plant in a container 10 inches or larger.

Tiny Tim

A very small plant with small cherry sized fruit. Truly tiny, this one is a great conversation piece as it only gets about 12 in tall! Ideal for a patio table when you have company over. This one can be grown in a very small pot, 6 inches or larger.

Jet Star

Both the plant and the fruit are not too big. Uncle Mike loves this tomato because it’s will be quick to produce nice medium size fruit with a thin skin. It’s also considered to be one of the least acidic tomatoes out there good for pots 12 inches or larger.

Black Krim

This is a nice heirloom variety is a medium-sized plant that produces medium-sized fruit. Purplish in color and very tasty, you can plant it in containers 12 inches or larger. Watch out for heavy watering or rain as they come close to ripening because they crack very easily!

Celebrity

This is medium to large tomato that’s on a determinate vine. If you want to try a large tomato in a container this on is the one to try. It’s crack resistant as well. Use a pot that’s at least 12 inches in diameter.

San Marzano

This is a sauce tomato but most sauce tomatoes are determinate so that means it’s a bush type plant and will tolerate containers. In addition to being great for sauce, these are awesome for salads, salsa, and cooking too!

Celano Patio Grape

This is our first dwarf grape tomato; it’s a semi-determinate hybrid with very sweet fruit. This plant will produce an abundance of grape tomatoes perfect for snacking! Best in containers that are 10 inches or larger.

Little Napoli

A fantastic sauce tomato you can grow right on your patio. Disease resistant, determinate, produces small oblong fruit, delicious in cooking or eating fresh from the vine!

 

Theoretically, a tomato can be grown in any size pot if you keep the plants watered and fertilized. But following Mike’s recommendations for container sizes will make it easier for you to enjoy the fruits of your labor (and it should mean less labor too!)

Weeping Ornamental Cherry Trees: A Gift From the East

Looking for a small, elegant and unique flowering tree for your landscape? One that is hardy, low maintenance and sure to draw admiring glances from your neighbors? Look no further than the weeping cherry tree. Available in pink and white flowering varieties, their delicate blossoms open along gracefully arching fine branches.

But weeping ornamental cherries are more than one-season wonders. Their glossy green foliage brings a sense of calm to the summer garden. With the arrival of fall, the leaves turn golden. In winter, the bronze bark offers rich color and interest. And despite their delicate appearance, weeping cherries are completely hardy and will come through our worst winters without missing a beat.

These trees first came to our country’s attention early in the 20th century. In 1912, the government of Japan gave a gift of 3,000 trees to the people of the United States. The first two trees were planted in a simple ceremony on March 27, 1912, by First Lady Helen Herron Taft and Viscountess Chinda, wife of the Japanese Ambassador to the United States, on the north bank of the Tidal Basin in West Potomac Park. With planting complete, the stunning display of flowering trees became known as The National Cherry Blossom Festival. Next year’s Festival is planned for March 20 – April 14. If you plan to be in Washington DC at that time, you are in for a treat!

And to bring the story full circle, in 1915 the United States Government reciprocated with a gift of flowering dogwoods to the people of Japan.

Check out our printable care guide for more information on planting and caring for these beauties!

Choosing the Right Pottery for Your Home, Porch, or Yard

Pottery is an investment that can add interest to your home and show off your personal style no matter what plants you choose to put in them. But with so many styles and colors to choose from, deciding what’s right for you and your plants isn’t totally straightforward. We are here to help demystify the process with a few things to keep in mind when choosing a container for your home, porch, or yard.

Size Matters.

When it comes to pottery, size is a major factor both for your budget and for the health of the plants you place in your pots. You may be tempted to go big so that you never have to re-pot but be careful! When plants are planted into containers significantly larger than their nursery pots the root system is not robust enough to absorb all the water in the soil and that can lead to root rot. A good rule of thumb when transplanting into a new container is that the diameter of the new pot should only be about two inches wider than the plant’s current pot.

If you fall in love with a decorative container that’s too large for your plant but you know that it will eventually grow into it you can slowly acclimate it to the larger pot using inexpensive grow pots that fit inside your decorative container or by using an Ups-A-Daisy, which will reduce the amount of soil you need in the pot until your plant’s root system is ready for more.

An Ups-A-Daisy can reduce the amount of soil needed to fill your pot!

 

On the flip side, you do not want to try to cram a plant in a six-inch diameter grow pot into another six-inch diameter decorative pot, particularly if the decorative pot has a tapered bottom. Never go smaller, your plants need room to grow.

 

Drainage and Airflow are Important.

You may have noticed that when you buy plants, they usually come in plastic containers with several drainage holes along the bottom. Air is every bit as important to a healthy root system as water. Roots cannot breathe when the soil is sopping wet, all the air molecules get crowded out by water molecules. If you are planning to transplant directly into a decorative container, drainage holes are a must. It is even better if you can get air moving under your plant. Pot feet or Ups-A-Daisys are a terrific way to do this.

Pot feet create airflow under your container.

 

Some decorative indoor containers are manufactured without holes so that indoor surfaces are protected. These are called cache pots and it is best to leave your plants in their grow pots (with all those drainage holes) and pop the whole thing into the container. Check out the video below for how to use a cache pot!

 

 

Different Materials Meet Different Goals.

Now that we understand the basics of size, drainage, and airflow, it is time to choose a container made from materials that meet your specific needs.

Terra Cotta

A favorite of plants everywhere and a classic that is making its way back into chic and modern home design, terra cotta is a smart choice for even moisture distribution and healthy roots. Because terra cotta is porous, oxygen exchange is facilitated throughout the root system, not just at the bottom. Additionally, terra cotta absorbs excess moisture to prevent plant roots from staying soggy for too long. These days, terra cotta is available not just in the classic earthy orange but also in attractive “chocolate” and “vanilla” tones to seamlessly integrate into any color scheme.

Terra cotta is the hands down favorite of most plants.

Glazed Pottery

Speaking of color, nothing offers the variety of hues like glazed ceramic pottery. Additionally, you will find a broad selection of shapes and sizes and many of these pots are crafted to be frost resistant. However, keep in mind that frost-resistant does not mean it is freeze-proof. Water expands when it turns to ice so moisture in your planters can push a ceramic pot to the breaking point during a freeze. Raising your outdoor pots off the ground with pot feet can help create airflow that will melt the ice during warmer days. When in doubt, it is best to empty your ceramic pots and bring them into the garage after Christmas to protect your investment. A dolly is helpful for this!

Lightweight Fiber Clay

Great for indoors or out, lightweight fiber clay offers the gravitas of stone with the easy maneuverability of durable plastic. Fiber clay is freeze-tolerant, making it a good option for year-round use but keep in mind, using ice melt around them will corrode the finish. Keep them looking great by avoiding the base of the pot when using ice melt.

Lightweight fiber clay, also known as fiber cement.

Plastic

If you know you will be moving your pots around to suit your design choices or crops each season, plastic is another great and affordable choice. It’s ideal for container gardening with herbs, veggies, and annuals and available in several different colors and finishes. Do be sure to bring these inside for the winter. Plastic will easily crack if it gets too cold. Fortunately, this is easy to do since they are so lightweight!

Plastic pots are easy to stack, store, and move throughout the season.

Cedar Boxes

The ultimate choice for New England, cedar boxes are classic, beautiful, and easily withstand freezing temperatures. Cedar will naturally weather to a lovely beachy grey tone, but you can preserve the original wood color by staining with a protective finish or paint to suit your color palette. Be sure to treat inside and out to prolong the life of the wood and if you are using the container for edibles, finish with non-toxic linseed oil.

Cedar boxes are the most durable choice for year round use.

Specialty Pots

Certain plants will benefit from specialized pots to live their best life. These include orchids, which are epiphytes and like their roots to be extremely well-aerated. That’s why orchid pots have holes in the sides to provide sufficient air circulation! On the other hand, African violets and ferns like to stay consistently moist and self-watering pots are great for this purpose.

Nine Shrubs to Prune in April

“Is this a good time to prune my…?” The question of when to prune is one we often hear. The confusion is understandable since some shrubs are best pruned in spring, others in summer, and still others prefer to be shorn in the fall.

Late winter or very early spring is the best time to prune shrubs that flower on “new wood” — the growth that forms in spring. Late March to mid-April is ideal. These shrubs form their flower buds in the spring and early summer, and bloom in the summer and into the fall.

Here are our favorite new wood bloomers who would love (and reward you handsomely) for a fresh spring haircut right now:

 

Butterfly Bush

Buddleia davidii
As you may have guessed from the name, these are pollinator favorites that offer lovely fragrant blooms late in the summer. To keep this shrub a manageable size, don’t be shy about pruning it to a height of 12-18 inches. Fortunately its branches are slender and easy to prune with hand-held pruners.

Buddleia

 

Bluebeard

Caryopteris spp.
These late summer bloomers will be covered in delicate looking blue flowers that draw butterflies, bees, beneficial insects, not to mention admiring comments from your neighbors. Like Buddleia, its branches are easy to cut and should be taken back to 12-18 inches. While this early spring pruning seems drastic, the plant will quickly flush new growth.

 

Rose of Sharon

Hibiscus syriacus
Rose of Sharon is valued for its late summer blooms that cover the shrub from top to bottom. However, if left unpruned, it will develop sturdy, but bare, upward growing branches and the flowers will be above eye level. An early spring pruning each year will keep the flowers where you can most enjoy them.

Hibiscus

 

Panicle Hydrangea (Limelight, Quick Fire, Bobo, Strawberry Sundae, etc.)

Hydrangea paniculata
These showstoppers have cone-shaped flowers that initially appear in white and cream tones before deepening to shades of pink and red. Once they reach maturity, this type of Hydrangea can be pruned to almost any height.

Panicle Hydrangea

 

St. John’s Wort

Hypericum perforatum
St. John’s Wart has been known for its medicinal benefits for hundreds of years. In our gardens, we love its yellow buttercup type flowers and red berries that we often use for holiday decorating. Pruning to a height of 12-18 inches and watch it rebound to a height of 3 feet!

 

Winterberry

Ilex verticillata
Winterberry is prized for its heavy showing of red berries that remain on the shrub well into winter before they are sweet enough to tempt the birds. This shrub is easily pruned to a size of your choosing.

 

Cinquefoil

Potentilla spp.
This collectible shrub offers a bright spot in the landscape with flowers in tones of yellow, pink, red or white. Its delicate leaves and gently spreading structure add to its appeal. Prune gently to keep it neat and tidy.

 

Roses

Rosa spp.
As our very own rosarian Jeannette likes to say, “when the forsythia blooms in New England, it’s time to prune your roses. Watch as Jeannette takes you through her tried and true techniques for early spring rose pruning.

 

Spirea

Spiraea spp.
With its brightly colored flowers, Golden elf is a steady performer and so easy to love for its easy care and longevity. Like Potentilla, it happily accepts pruning in early spring.

 

You might be saying what about Rhododendrons and Azaleas? And our beloved Lilac and Forsythia? Don’t worry about those just yet, they are best left alone in early spring. Fear not, we’ll be sharing some information about pruning these shrubs when the time is right (Hint: after they flower!)

Spring Pruning Basics for New England

Shrubs add beauty and structure to our gardens. During the first few years after planting, a shrub requires little to no pruning. As it matures, selective pruning can increase bloom, improve shape and or reduce size. Whatever your objective, intentional pruning helps produce a natural looking shrub with a graceful form. Below we’ll walk through the basics of spring pruning from tools to technique!

Choose the right tools.

Use clean, sharp hand tools rather than electric shears. Shearing a shrub promotes dense growth at the branch tips. This blocks light and inhibits air circulation inside the shrub, which can eventually lead to the shrub’s decline, either by disease or lack of foliage for photosynthesis. And remember to always disinfect your tools with rubbing alcohol before you begin.

Keep two thirds!

A shrub is not a poodle. Never remove more than one-third of the shrub’s mass in any given year. This preserves enough foliage for the plant to make sufficient food to stay robust and generate new growth quickly.

Choose a pruning method that meets your goals and the plant’s needs.

A “heading cut” is used to shorten a branch. The direction in which the top remaining bud is pointing will determine the direction of new growth. Prune one quarter inch above the bud, making the cut at a slight angle.

A “thinning cut” reduces the density of the shrub by removing branches at their point of origin from the center of the shrub.

Clean up.

Always remove dead, diseased or broken branches as soon as you notice them.

With few exceptions, you should avoid coating pruning cuts on shrubs or trees with wound dressing or paint. Trees and shrubs have their own mechanisms to heal a wound and need oxygen for proper recovery. In some cases wound dressings inhibit the availability of oxygen which is needed for proper recovery.

Know when to prune.

Different shrubs should be pruned at different times of the year depending on their individual biological make-up and bloom season. Read our blog on Nine Shrubs to Prune in April for some of the common favorites who would benefit from an early trim!

Now Blooming in the Nursery: Forsythia

Forsythia x intermedia ‘Lynwood Gold’

The bright yellow flowers of Forsythia are a sure sign that winter is behind us. Long a staple in gardens throughout New England, we sometimes take these familiar stalwarts for granted. But here is a variety that will inspire you to renew your acquaintance with this useful shrub.

Forsythia ‘Lynwood Gold’ offers the largest flowers of any Forsythia, creating a spectacular display. It has deep golden yellow flowers which literally cover the branches with bloom. The effect is stunning. The foliage emerges after the flowers fade and in autumn, the leaves turn a lovely butter yellow.

Upright in its growth habit, ‘Lynwood Gold’ will grow 6’-8’ in height and a similar width. It is easily pruned to maintain a desired size; however, pruning should be done immediately after flowering as flower buds for next spring will form during this summer. A mid-summer or fall pruning will remove next year’s flower show.

Forsythia performs best in full sun. It can be grown as a specimen plant or planted in a row to create an attractive deciduous hedge. And who can resist cutting a few branches of Forsythia as the blooms begin to open and bringing them indoors for a beautiful spring bouquet!

How-To: Pruning Your Roses

 

When the forsythia blooms, it’s time to prune your roses! Our very own rose expert, Jeanette, loves roses and loves to show what she knows about them. Join us as Jeanette takes us step by step through her guide to pruning roses in early Spring. Note: the roses featured are Hybrid Tea roses that will benefit from a prophylactic dose of fungicide or neem oil after pruning. Other varieties are such as Knock Out Roses or David Austin are less susceptible to such issues and you can skip that step with those!

Growing Citrus in New England – don’t be afraid to try!

When we think of citrus in the US most of us call to mind the warm and sunny climates in Florida and California where oranges, lemons, limes, grapefruits, and kumquats can flourish outdoors. But even in New England, where our winters are not exactly conducive to growing tropical plants, we can get creative and enjoy fragrant citrus blossoms, gorgeous glossy foliage, and homegrown vitamin C! 

 So, if you’re a Bay Stater looking to enjoy your very own oranges or fresher than fresh lemonade, we’re here to help! Here are a few things to keep in mind when growing citrus in Massachusetts:

 

Location, location, location.  

Citrus plants are hardy in zones 8, 9, and 10 and won’t survive winters outdoors here in zone 6 so it’s important that you ensure your citrus plants have a winter residence inside your house as well as a summer home outdoors. Offer at least a few hours of direct sunlight each day all year round. What does “direct sunlight” mean indoors? Placing your citrus plant within 3-4 feet of a South-facing window with unobstructed light (be sure to check for interfering shade trees or overhangs outside) is ideal. South-facing windows offer the greatest amount of light throughout the day. A close second when it comes to bright indoor light is western exposure where you get a few hours of strong afternoon sun each day. 

 

How can you tell which direction your windows face?  

  1. pay attention to where the sun rises and sets in relation to your home (the sun rises in the east and sets in the west) 
  2. locate your home on GPS to find the cardinal direction your home faces.
  3. Use a compass, simple but highly effective. 

No south-facing windows? You may still be able to give citrus a go! Try out a grow light or start with a very small citrus plant and you may be able to help it adapt to lower light conditions! 

 

Tips for relocating your citrus when the time comes: 

  1. Choose a smaller variety that’s easier to move. Good choices include tangerines, ponderosa or Meyer lemons, and Satsuma or Calamondin oranges.
  2. If you want to use a larger variety, consider adding a plant dolly on casters to make it easy to roll in and out of the house.
  3. Remember that when you bring your citrus outside for the summer it will need to gradually acclimate to full sun. Start by placing the tree in a semi-shady location and move it little by little into full sun over two weeks.  

 

Temperature.  

Citrus plants say brrrrrr when temperatures dip below 50 degrees at night. Watch the weather for a clue as to the best time of year to bring your plants indoors. Indoors, citrus plants are happiest when they are kept in temps between 65 and 70 during the day and 55 to 60 at night.  

 

Water

Citrus plants will be happiest if soil is evenly moist but not too wet. A moisture meter is something to consider when growing citrus. During the summer when your container is outdoors in full sun, give a thorough watering twice each week. Use a watering wand or watering can to separate the stream and mimic rain and water the entire surface area of the soil until you see a little water dribble out of the drainage holes. In winter, you’ll water less but you may want to consider using a humidifier to mitigate the dry indoor air. Check out our winter watering guide for more tips! 

Avoid putting your citrus plants in the same room as a wood-burning stove. This may create conditions that are far too dry for healthy citrus to thrive. 

 

Pollinating

Citrus flowers need to be pollinated to set fruit, and the most important pollinators for citrus trees are bees! So, if you want fruit you’ll need to ensure that your citrus plants spend the warm months in their summer home for plenty of playtime with their winged buzzing friends.  

If your citrus plant sets flowers during the winter months, you’ll need to manually pollinate with a paintbrush or Q-Tip. This is easy enough to do. Gently brush the pollen-covered anthers with a paintbrush and then touch your brush to the stigma in the center of the flower. Check out this video to see how easy it is! 

 

Fertilizing.  

Citrus plants are heavy micro-nutrient feeders and require a special diet to stay healthy. We recommend fertilizing with True Organic Citrus and Avocado Food or Espoma Citrus Tone every 3-4 weeks during the growing season (March – August). Avoid feeding your plant during the winter months, this is the time to avoid encouraging new growth. Let them rest. 

 

Pest management.  

Like all fragrant plants, citrus has a habit of attracting unwanted pests. To mitigate this, give your plants a good shower with a hose before bringing them inside for the winter. Let them dry then spray all the foliage and stems with Captain Jack’s Citrus, Fruit, and Nut Orchard Concentrate or neem oil.  

Growing tropical plants outside the tropics isn’t easy but it’s oh so satisfying. Remember to be patient with yourself and with your plants…when it comes to plant cultivation, there is no such thing as a green thumb or a black thumb. It’s the patient, inquisitive thumb that will find the greatest rewards.
