Gardening in Delaware -June Schedule

Gardening in Delaware -June Schedule

Lots of gardens are well on their way to being established by June in Delaware, but have no fear! If you haven’t yet planted, you can still go for it throughout June, you just may need to use more nursery-bought transplants to get it done! And some seeds can even be sown directly in the ground and can easily catch up due to our extended growing season.

Gardening in Delaware June Schedule

Delaware has 3 gardening zones depending on where you live: 6b, 7a & 7b. Be sure to know which zone you are in so you plant at the right time for your zone.

Pollinator Highlight: The Sunflower

The sunflower is a top pollinator plant for all insects, especially bees and butterflies! Gorgeous colors for bouquets, a great food source, and a kid-favorite, these quick-growing blooms are a rewarding way to nurture our pollinators. The mammoth is our favorite, but any sunflower variety will do.

If you are interested in specifically helping the monarchs this year, consider planting milkweed in your garden, which is their primary food source. You can learn more and get free seeds here: and you can also find established milkweed to transplant at your local plant nurseries.

Most of the indoor sowing is finished for spring and summer, but don’t forget about Fall crops! Here in Delaware, we can get a jump start on our fall gardens by sowing these seeds indoors:

  • All winter squashes for a fall harvest
