4 Seasons Gardening

To help you make the most of your gardening efforts throughout the year, let’s delve into a month-by-month guide tailored to the specific conditions of New England.


While the cold winter months may limit outdoor gardening activities, January is the perfect time to start planning for the upcoming growing season. Take this opportunity to sketch out your garden layout, order seeds, and assess any tools or supplies that may need replenishing.


In February, as temperatures begin to slowly rise, it’s essential to start your indoor seeds for vegetables and flowers that require a longer growing season. Consider setting up a small indoor growing area with sufficient light and warmth to give your plants a head start.


As the promise of spring looms near, March is the ideal time to start prepping your garden beds. Clear away debris, amend the soil with organic matter, and sow cold-hardy vegetables like lettuce and radishes outdoors. Keep an eye on the weather forecast and be prepared to protect your early plantings from any late frost.


April flowers bring bees for early pollination and establishing a good summer start

With the arrival of April, the gardening season kicks into high gear. Transplant seedlings started indoors, direct sow frost-tolerant vegetables such as peas and carrots, and divide perennials to encourage healthy growth. Take advantage of the increasing daylight hours and warming temperatures to get your garden in full swing.

  1. Get your spring flowers planted to attract pollinators
  2. Enhance your pollination chances for summer/fall yields
  3. Revitalize any potted garden soils for summer growth
  4. Nip any spring pests and diseases before they start
  5. Prune dead growth before new growth kicks in
  6. Prepare your compost pile for readying summer usage


May marks the transition to warmer weather, allowing for a wider variety of plants to thrive. Plant warm-season vegetables like tomatoes and peppers, as well as annual flowers to add color to your garden beds. Begin regular maintenance tasks such as weeding, mulching, and watering to keep your garden looking its best.

  1. Adjust mower height for optimal soil moisture retention
  2. Get ready for summer by overcharging your spring compost pile
  3. Plan on starting these vegetables in May for summer yields
  4. Get on top of spring pruning to maximize summer yields
  5. Take advantage of spring propagation for perennial flowers
  6. Protect your young trees from early spring weather fluctuations

In the heat of July, garden maintenance becomes crucial to ensure plant health. Water deeply in the morning to avoid evaporation losses, apply organic fertilizers to support vigorous growth, and stake tall plants to prevent them from toppling over. Stay on top of harvesting to enjoy the fruits of your labor.

  1. Consider protecting heat-sensitive plants from the sweltering sun

  3. Replenish mulch for optimal moisture retention and weed management

As autumn approaches, harvest your summer crops and begin transitioning to your fall garden plan

As summer reaches its peak, August is a time of both abundance and preparation for the fall season. Continue harvesting vegetables at their peak ripeness, start planning for fall crops such as kale and spinach, and save seeds from your favorite plants for future seasons. Keep an eye out for signs of fatigue in your garden beds and consider revitalizing the soil with compost.

  1. Fall is coming, start planning on how to transition your garden for fall crops
  2. Prevent pests by performing autumn pruning and cleanup of your garden
  3. Keep up morning watering for autumn gardens
  4. Revitalize your garden’s soil to ensure a bountiful fall yield
  5. Adjust your mowing routine to promote a healthy autumn lawn


Transitioning into the cooler months, September signals the start of the fall gardening season. Plant cool-season crops like lettuce and radishes, clean up spent summer annuals and divide and transplant perennials for a fresh start next year. Begin composting fallen leaves and garden debris to enrich your soil for the following year.


With the arrival of autumn, October brings a burst of color and a slower pace in the garden. Take this time to plant spring-blooming bulbs, clean and store garden tools, and prepare perennial beds for winter dormancy. Consider adding mulch to protect tender plants from frost damage and insulate the soil.


As the gardening season winds down, November provides a moment of reflection and preparation for the months ahead. Cut back perennial foliage, remove any remaining annuals, and tidy up garden paths and borders. Consider starting a winter compost pile with kitchen scraps to enrich your soil come spring.


As winter settles in, December offers a brief respite before the gardening cycle begins anew. Use this time to plan next year’s garden, browse seed catalogs for inspiration, and tend to any indoor plants that may need extra care. Embrace the restorative power of nature’s dormant period as you recharge for the upcoming growing season.
