FLOWER GARDEN TASKS:
Once all chance of frost has passed, plant seeds of summer annuals such as easy-to-grow cosmos, nasturtiums, sunflowers, and zinnias.
After azaleas, camellias, and rhododendrons finish blooming, remove spent blooms, taking care not to damage the new growth just beneath them. Feed the plants with a fertilizer especially developed for acid lovers.
VEGETABLE GARDEN TASKS:
Early in the month, sow in the garden seeds of cool-season veggies such as carrots, chard, and spinach.
Late in the month, sow seeds of warm-season crops such as beans, corn, and squash; set out seedlings of eggplant, peppers, and tomatoes.
Clear away weeds from the base of trees. Weeds compete with trees for water and soil nutrients. If you mulch around the base of the tree to help conserve water and prevent weed growth, remember to keep the mulch clear of the tree trunk, as mulch provides a wonderful habitat for insects, and fungus to infect the trunk.
Also this is a great time to check your watering system. Make sure drippers are functioning, and the amount you are watering is correct for your tree growth and size.
