It’s May and even for the northernmost planting zones, spring is here! May is a busy month in the garden. If you’ve kept up with your late winter/early spring gardening chores, then it should be an enjoyable one for you!
While it’s tempting to plant everything at the first sign of a warm day, May has a tendency to bring unexpected weather that can damage your garden. Late cold snaps, heavy rains and strong winds are all still possible, so be prepared to protect your garden from inclement weather.
If you have specific questions about the best times to plant in your area, always seek the advice of a trusted garden center or your local county extension office.
May Garden Planning
If you kept up with your late winter/early spring chores and planning, May should be a little easier. Still, it’s worth noting in your garden journal any successes you’ve experienced with your plantings. Is there something that you might have planted sooner (or later) than you did? What pests are you observing in the garden so far? How much rain are you getting?
Spring Garden Prep & Maintainance
It’s important to keep up with weeding and to reapply mulch if you see any bare spots on the soil surface. Be sure your irrigation system continues to operate efficiently as the growing season heats up. If you live in an area with watering restrictions or guidelines, make sure your watering schedule honors that. Fertilize fruit trees with compost, and thin fruit to every 6” while the fruit is still small.
USDA Hardiness Zone 4 should harden off annuals before transplanting them outside and can remove winter protection from cool-season crops.
