Green Beginnings: A Beginner’s Guide to Seed Starting in New England

The world of gardening in New England can be a whirlwind, where the seasons change when they want, and the growing season can sometimes feel fleeting. If you’ve ever dreamt of cultivating your own lush garden, there’s no better way to kickstart the process than by mastering the art of seed starting. In this beginner-friendly guide, we’ll take you through the basics of seed starting in New England, helping you turn those green dreams into a reality.

 

Understanding Your Zone

New England’s diverse climate spans USDA Hardiness Zones 4 to 7, meaning we experience cold winters and warm summers. Understanding your specific zone is crucial for selecting seeds that thrive in your local conditions. The USDA Plant Hardiness Zone Map is an excellent resource to identify your zone and plan your gardening calendar accordingly. You can find our blog post on the recent change in the zone map here!

 

Choosing the Right Seeds

Selecting the right seeds is like choosing the cast for your gardening production. Consider factors such as your region, soil type, and sunlight availability. For New England, cool-season crops like lettuce, kale, and broccoli are perfect for early spring, while warm-season crops like tomatoes and peppers can be started indoors in late winter. But don’t worry, we’ve made it easy for you, take a look at our table that shows you exactly what to plant and when here!

 

Seed Starting Calendar

 

 

Timing is Everything

In New England, where frost dates can be unpredictable, timing is key. Consult your local agricultural extension office or use online resources to determine the last frost date in your area. Count backward from this date to determine when to start your seeds indoors. This ensures your seedlings are strong and ready to be transplanted when the soil is warm enough.

 

Creating the Ideal Environment

Set up a dedicated space for your seeds to germinate and grow. Ensure they receive sufficient light, either from a south-facing window or using artificial grow lights. Maintain a consistent temperature, ideally between 65-75°F (18-24°C). Regularly check soil moisture and avoid overwatering, as New England’s cool indoor environments can slow down drying times.

 

Now you’re ready to get started!  Let’s go step by step.

Step 1: Gather Your Supplies

Before diving into seed starting, gather the essential supplies. New England’s variable weather conditions make indoor seed starting a smart choice, allowing you to control temperature and protect delicate seedlings from unexpected late frosts.

Collect all the necessary materials before you start:

 

Step 2: Choose the Right Seed Trays

Opt for trays with drainage holes to prevent waterlogging. Cell trays or peat pots work well for individual seeds. Make sure the trays are clean and have been disinfected to minimize the risk of disease.

Step 3: Fill Trays with Seed Starting Mix

Use a high-quality seed starting mix that provides good aeration and drainage. Fill each cell or container, leaving a little space at the top for watering.

Step 4: Planting Depth and Spacing

Check the seed packet for specific instructions on planting depth and spacing. As a general rule, plant seeds twice as deep as their diameter. Small seeds can be surface-sown.

Step 5: Watering

Moisten the seed starting mix before planting to ensure even water distribution. After sowing, use a gentle stream of water or a spray bottle to avoid disturbing the seeds. Keep the mix consistently moist but not waterlogged.

Step 6: Covering Seeds (Optional)

Some seeds benefit from being covered with a thin layer of vermiculite or seed starting mix to maintain moisture. Refer to the seed packet for specific instructions. You can also use plastic wrap or a humidity dome to create a mini greenhouse effect until the seeds germinate.

 

Step 7: Temperature and Light

Place the trays in a warm location to encourage germination. A consistent temperature between 65-75°F (18-24°C) is ideal. Once germination occurs, move the trays to a well-lit area. If using natural light, ensure your seedlings receive at least 6-8 hours of direct sunlight. If not, supplement with grow lights placed a few inches above the seedlings for 14-16 hours per day.

Step 8: Thinning Seedlings

As seedlings grow, thin them to ensure proper spacing and prevent overcrowding. Choose the healthiest-looking seedlings and snip the weaker ones at soil level.

Step 9: Hardening Off

Harden off your seedlings by gradually exposing them to outdoor conditions for a week before planting. This helps them adjust to the changes in temperature, sunlight intensity, and wind, reducing the risk of transplant shock when they are finally moved into the garden.  Select a sheltered outdoor location for your seedlings. A porch, patio, or any area that provides partial shade and protection from strong winds is ideal.  We recommend the following hardening off schedule:

 

Day 1-2: Introduce to Shade

On the first day, place your seedlings outdoors in a shaded area for 1-2 hours. Gradually increase the time each day, exposing them to a bit more sunlight. Monitor them closely for signs of stress, such as wilting or leaf burn.

Day 3-4: Partial Sun Exposure

Move the seedlings to an area with dappled sunlight or morning sunlight for a few hours. Again, increase the time they spend outdoors each day. Ensure they are protected from strong midday sun during this phase.

Day 5-6: More Sun Exposure

Expose the seedlings to direct sunlight for longer periods, gradually increasing their exposure. By this point, they should be able to handle a few hours of direct sunlight without adverse effects.

Day 7-10: Full Sun Exposure

Towards the end of the hardening off period, your seedlings should be ready for full sun exposure. Place them in direct sunlight for most of the day, mirroring the conditions they will experience in the garden.
Keep a close eye on your seedlings throughout the hardening off process. If you notice any signs of stress, such as wilting or discoloration, scale back the exposure and increase gradually again. As your seedlings spend more time outdoors, they may require more frequent watering due to increased exposure to wind and sun. Keep the soil consistently moist but not waterlogged. During the hardening off period, be cautious of nighttime temperatures. If frost is forecasted, bring your seedlings indoors or provide them with some protection.

 

Once your seedlings have successfully completed the hardening off process and show no signs of stress, they are ready to be transplanted into the garden.

 

 

Step 10: Transplanting with Care

Once your seedlings have developed sturdy roots and a couple of true leaves and the danger of frost has gone, it’s time to transplant them into your garden. Choose a sunny location and prepare your soil with compost and Bio-Tone Starter to give your plants the best start possible.

 

Step 11: Ongoing Care

Congratulations, you’ve successfully started your seeds and transplanted them into the garden! However, the journey doesn’t end there. Regular watering, weeding, and monitoring for pests are crucial for a thriving garden. Stay connected with us as we post blogs and tips specific to New England’s unique challenges.

Armed with the knowledge of your local climate, careful planning, and a bit of patience, you’ll soon be enjoying the fruits (and vegetables) of your labor. Happy gardening!

 

Unwrapping the Magic: The Fascinating Story of Poinsettias and Tips for a Flourishing Holiday Season

 

Welcome to the enchanting world of Poinsettias – those vibrant bursts of red, pink, and white that herald the holiday season. As you prepare to deck the halls with these festive favorites, let’s dive into the rich history, captivating biology, and practical care tips that make the Poinsettia a cherished symbol of joy and warmth. 

 

A Blooming History

The Poinsettia’s journey from the sun-drenched landscapes of Mexico to the heart of holiday celebrations worldwide is nothing short of magical. Native to southern Mexico, the plant is known as “Cuetlaxochitl” in Nahuatl, the language of the Aztecs. These ancient people prized the plant for its brilliant red bracts and utilized its sap for medicinal purposes. 

Joel Poinsett, the U.S. Ambassador to Mexico in the early 19th century, encountered this botanical gem during his diplomatic tenure. Struck by its beauty, he sent samples back to his home in South Carolina, introducing the Poinsettia to the United States and sparking its meteoric rise to seasonal stardom. 

 

Flourishing in Mexico’s Landscape

In its native habitat, the Poinsettia isn’t confined to a decorative pot; it naturally grows into large, lush shrubs, transforming the Mexican landscape with a riot of colors. This perennial evergreen shrub, known botanically as Euphorbia pulcherrima, thrives in the warm, subtropical climates of Mexico and Central America. 

Reaching heights of up to 10 feet, the wild Poinsettia graces hillsides and open areas, contributing to the vibrant tapestry of Mexico’s flora. Its adaptability to varying soil types and preference for well-draining conditions make it a resilient presence in the natural environment. 

 

Behind the Brilliance: Bracts and Flowers

While the Poinsettia’s beauty is undeniable, it may surprise you to learn that what we commonly perceive as petals are, in fact, specialized leaves known as bracts. These bracts are responsible for the plant’s stunning array of colors, ranging from classic red to elegant white, and soft pink. Nestled within these vibrant bracts are the Poinsettia’s tiny, inconspicuous flowers, located at the center of the plant. It’s a true marvel of nature, where the leaves steal the spotlight, and the flowers work their magic quietly. 

 

Poinsettia Care 101

Now that you’re enchanted by their history and beguiled by their unique biology, let’s ensure your Poinsettias thrive throughout the holiday season and beyond. Here are some friendly tips for keeping these botanical wonders happy: 

 

Light and Location

  • Poinsettias love bright, indirect light, so find a cozy spot near a window with filtered sunlight
  • Avoid placing them in drafty areas, as they prefer a stable temperature.

 

Watering Wisdom

  • Allow the soil to dry out slightly between waterings
  • Overwatering can lead to root rot, so moderation is key to a healthy Poinsettia

 

Feeding Fun

  • Fertilize your Poinsettia every 2-4 weeks during the growing season (spring and summer)
  • Opt for a balanced, all-purpose fertilizer to keep those bracts looking vibrant

 

Extended Joy

  • To encourage reblooming, reduce the amount of daylight your Poinsettia receives starting in October
  • Keep them in complete darkness for 14 hours a night, ensuring they get 10 hours of bright light during the day. This mimics the natural conditions that trigger blooming
