Colder climates may still be shrugging off winter, but most gardeners are excited to be back to work by April. Dry summers in California and the American Southwest call for drought-tolerant plantings and water-wise practices. Butterflies signal spring’s return in the Great Lakes region and elsewhere, while flowering native trees make their presence known in the Northeast. In Texas and the Southeast, warming temperatures mean everything from herbs to vegetables to annuals can be sown from seed. Here’s what to do in your garden, by U.S. region, this April.

"It’s also smart to protect the shoots of emerging perennials, which are susceptible to damage.

"One of my favorite native trees for the northeast is Eastern redbud (Cercis canadensis)," writes Vermont landscape consultant Charlotte Albers.

Grow this small tree in full sun as a focal point, in an open setting or along the edge of a woodland for visual interest in early spring."
