The U.S. Department of Agriculture's new plant hardiness zone map has been updated for the first time since 2012. It reflects rising temperature trends and Delaware is in a new zone with warmer temperatures.
The Delaware Center for Horticulture has suggestions for garden planning at home, such as finding an area that gets ample sunlight but also offers some afternoon shade.
That area should also have adequate moisture and be in the flattest area of your yard. Avoid slopes, hills, or sunken areas at the very least.
Olivia DiFilippo with the Delaware Center for Horticulture also recommends a good starting time for your garden.
"So, a lot of folks will say you want to wait until after Mother's Day to plant your veggies outside. That's like a pretty easy rule to remember,” said DiFilippo. “Some things however can be planted before or after your last frost date. Some veggies like your brassicas, spinach, greens, they can benefit from a little bit of cold weather. It actually helps your crop taste sweeter."
She adds at this time of year, weed eradication is key.
"Typically for garden prep and especially for cutbacks, you want to wait until you have five days of about at least 50-degree weather that gives time for beneficial insects and native bees to leave what is their hibernation period," said DiFilippo.
DiFilippo adds that another important tip is to use leaves as a natural compost and mulch, and to start mulching when adding new plants.
