There are still seeds you can put in the ground in March. It's also time to plant summer vegetables, while still planting for another crop of your current winter-grown veggies. If you had frozen veggies this winter, you can replant those now and get a crop before the heat hits.
It's too late to start many cooler season vegetables, such as broccoli and greens, from seed, but you can buy starter plants and possibly get another harvest before hot weather hits.
Heat resistant annuals such as Zinnia, Marigold, and Cosmos are excellent choices to add color during warmer weather. Plant Coleus seeds now for everlasting summer color.
