When Can I Start Planting?March 27, 2023
A Guide to Spring Using USDA Map Zones
The first week of spring is officially here. While temperatures around the region have begun to warm up, there are still frost warnings in our area of the Brandywine Valley. Many homeowners are wondering when they should begin getting their outdoors ready.
According to the USDA Map of the United States, this area of Delaware and Pennsylvania is ranked Zone 7. That means that temperatures are generally mild this time of year – not as hot as the South and not as cold as New England. Keep in mind there are two areas of Zone 7 as well. Zone 7a’s lowest temperatures hit a few degrees cooler than Zone 7b’s.
The relatively comfortable climate of Zone 7 means a large variety of trees and plants can thrive here.
Cool weather vegetables such as cabbage, onions, potatoes and kale can usually be planted in late February to early March. Lettuce, tomatoes and herbs should be planted in late April to early May.
You’ll want to wait until the last frost, which is usually between the end of March and beginning to April, to begin putting flowers outside. Even then, make sure temperatures have been consistently above 50 degrees to make sure they don’t freeze.
Flowers in Zone 7 that do well include Black-Eyed Susan’s, sage, lavender, catmint, roses, hydrangeas and canny lilies.
