Harnessing Nature’s Army: Banker Plants and Beneficial Insects in the Greenhouse

If you’re an avid gardener or just someone who loves to immerse themselves in the beauty of plants, you might have heard of Integrated Pest Management or IPM. IPM is a smart and sustainable way to handle pests. Instead of relying solely on chemicals, IPM uses a combination of techniques like biological control (using beneficial insects as natural predators), crop rotation, diligent and frequent scouting of plants for pests, and traps.  By understanding pest behaviors and the ecosystem, IPM aims to keep pests at manageable levels without harming the environment.  It’s all about smart strategies that protect crops and gardens effectively while being mindful of nature’s balance.

An amazing tool in the IPM tool kit is the incredible duo of banker plants and beneficial insects. But what exactly are they, and how do they work their magic in greenhouse spaces? Let’s dive in!

 

Banker Plants: The Silent Guardians of Greenhouses

Imagine a bustling metropolis where every citizen has a role to play in maintaining peace and harmony. In the world of greenhouses, banker plants are the unsung heroes playing a similar role. But what exactly are banker plants?

Banker plants are sacrificial plants strategically placed within a greenhouse to attract and sustain populations of beneficial insects. These plants act as a food source, habitat, or breeding ground for these tiny warriors, allowing them to thrive and multiply.

Beneficial Insects: Nature’s Pest Control Squad

Now, let’s meet the stars of the show – beneficial insects. While the term “insect” might conjure up images of creepy crawlies, these tiny creatures are the knights in shining armor of the plant kingdom. Beneficial insects are nature’s own pest control squad, preying on harmful pests that threaten the health of greenhouse plants.

Lacewings, predatory mites, and parasitic wasps are just a few examples of beneficial insects that can be deployed in greenhouse spaces. These tiny warriors patrol the leaves, stems, and soil, seeking out and devouring pests like aphids, mites, thrips and whiteflies, keeping the greenhouse ecosystem in balance.

Here at Mahoney’s our tiny warriors are a type of insect known as Orius Insidiosus, also known as Minute Pirate Bug, who feed on smaller insects, spider mites, thrips and other common plant pests.  Interested in learning more about these greenhouse pirates?  Check out Cornell University’s informational page here!

The Greenhouse Harmony: How Banker Plants and Beneficial Insects Work Together

Now that we’ve met our heroes, let’s see how they team up to keep the greenhouse clean and green without the need for harmful chemicals.

  1. Attract and Sustain: Banker plants act as a beacon, luring beneficial insects into the greenhouse with their enticing aroma and nectar-rich flowers. Once inside, these insects find a haven where they can feed, breed, and establish their population.
  2. Hunt and Protect: Beneficial insects, fueled by the resources provided by banker plants, scour the greenhouse in search of prey. When they encounter harmful pests, they unleash their natural predatory instincts, effectively keeping pest populations in check.
  3. Ecosystem Balance: By harnessing the power of nature’s own pest control mechanisms, greenhouses can achieve a delicate balance within their ecosystem. Rather than resorting to chemical pesticides that can harm beneficial insects and disrupt the natural order, they can rely on banker plants and beneficial insects to maintain a harmonious environment.

The Benefits of Going Green with Banker Plants and Beneficial Insects

Embracing banker plants and beneficial insects offers a plethora of benefits:

  • Environmentally Friendly: By reducing reliance on chemical pesticides, it’s not only safeguarding the health of the plants but also minimizing the ecological footprint.
  • Improved Plant Health: With pests kept in check, plants can thrive without the stress of constant attacks, leading to healthier growth and higher yields.
  • Enhanced Biodiversity: By fostering a diverse ecosystem within greenhouses, it’s more than just growing plants; it’s nurturing a vibrant community of insects and microorganisms that contribute to overall ecosystem health.

 

Mahoney's Winchester Banker Plants

The banker plants and their insects have been hard at work at our growing greenhouses in Woburn as our Mahoney’s Grown plants mature.  But now that these plants have been sent to any one of our 7 locations, the banker plants have gone with them to keep the plants happy and healthy until you can take them home.

Next time you visit one of our greenhouses you may see a plant with a sign proclaiming ‘Banker Plant’, be sure to stop by and say hello to our tiny warriors!

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

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!)
