Time to Thin and Weed
As we approach the second half of May it’s time to start weeding and thinning in earnest. Thin your beets and carrots 2 weeks after they emerge to keep them growing vigorously. If you want to keep the weeds under control and save your aching back hoe regularly on sunny days and hand weed when the ground is wet. Learn more about The Importance of Thinning from our blogpost.

Time to Plant First Corn, Cucumber and Bean Successions

Our bean growing guide and Southern Pea growing guide will tell you how.

Egyptian Onions and Other Perennial Alliums
Perennial alliums are really lovely at this time of year with bulbils, flowers and seed heads putting on an interesting display. May/June is a good time to preorder, garlic and Egyptian onion bulbs for delivery  at the correct fall planting time for your area (mid-September to Mid-October) to avoid disappointment when you favorite varieties are unavailable later in the season. For more growing info read SESE’s Garlic and Perennial Onion Growing Guide.

Time to Transplant  Tomatoes, Peppers, Eggplant and  More!

You may want to plant eggplant into bare soil and cover with light weight row cover or proteknet for better control of flea beetles. If needed a bucket made sticky on the inside with tangle foot makes a nice trap for flea beetles. Put the bucket under your plant and just shake’em in. Happy gardening!
