What Seeds to Plant in March
Updated: May 1, 2019
Growing tips for starting seeds indoors
It’s recommended to use grow lights, as seedlings may not receive enough light for strong growth even in a window. It takes about 6-8 weeks for these varieties to grow to transplant-size when started from seed. Therefore, by starting these seeds in March, the seedlings will be ready to plant outdoors in the garden in May, just in time for the weather to be warm enough to plant them outside.
Furthermore, it’s important to harden off your seedlings before planting outdoors. Keep an eye on the extended weather forecast and look for the air temperature to remain warmer than 50F before planting these summer veggies.
Ginkgo Gardens has everything you need for starting seeds, including seedling trays and pots, seed-starting soil, heat mats, and the following seed varieties below.

Growing tips for direct sowing seeds outdoors
These varieties are super-speedy growers, ready to harvest in about a month (peas take a little longer, so plant extra to harvest as pea shoots while you wait). Regardless, you'll be able to harvest all of these before you'll need the outdoor space for the veggies you started indoors for May planting.
When planted after the soil temperature reaches 50F or warmer, these varieties tend to germinate in less than 2 weeks (source).
