In the Northeast, gardeners are thrilled for June to arrive. Although there is a lot of variety in climate from Maine down to Maryland, this entire region finally enters summer and the growing season by June.

Gardening in the Northeast

The states in this region are generally considered to be Connecticut, Rhode Island, Vermont, Massachusetts, Maine, and New Hampshire. While this area may not warm up as quickly as some states, gardening in the Northeast is at full swing in June.

Assuming you have been a good gardener and done the chores in the yard necessary for your region, late spring/early summer is the time to really play. June provides the double hit parade of longer days of sun and increased temperatures.

  • June is a good time to feed anything that is already in the ground. Use a time release fertilizer to avoid burning plant roots and give gentle nutrients that will last for several months.
  • Stake vines and veggies as needed and deadhead your flowers to encourage more and enhance the appearance of beds and containers.
  • Mulch or top dress around vegetables to prevent weeds and conserve moisture.
  • It isn't too late to plant in June, even by seed, and your efforts and care will result in a season of glorious flowers and bountiful veggies.

June 20th is the start of summer and June planting in the Northeast is all about vegetable gardening for a summer and fall harvest, but it's also a great time to install many bushes and perennials.

You can still plant quick start annuals like zinnias, marigolds, cosmos, sunflowers, nasturtiums, and four o'clocks. Now is a good time to start perennials and biennials from seed. Prepare a bed in a protected spot from blazing sun and sow seed for next year's plants. Now is also a great time to get annuals and start window boxes and hanging baskets. Keep them well watered and you will have color all summer long.
