I don't really have a whole lot of outdoor space where I live. What can I grow, say, on my window? —Paris Alston, co-host, GBH’s Morning Edition

There are plenty of options, Epstein said. He suggested microgreens, parsley or basil in sunnier spots.

One thing to avoid: tomatoes.

“You need pollination with the tomatoes, and I'm sure you don't want to start putting bees in the house and things like that,” he said. “They also need good airflow. Tomatoes just don't do well inside. You can do it, but you'd need special grow lights.”

Memorial Day is almost here. Are we out of frost season? What should I plant?

That’s likely, Epstein said.

“I don't see any frost this morning, although there are some places on the Vineyard that are in the mid-30s, so there could be a little bit of light frost down there this morning,” he said. “We're kind of out of what I see as a frost window, so if you want to put stuff out, go ahead.”

Some things to try planting: Impatiens and begonias, which bloom beautifully and add color. “I put mine in yesterday,” Epstein said. “For pops of color where you don't get a lot of sun, impatiens work great, begonias work great.”

Also likely good to go: Tomatoes and peppers.

One thing to wait to plant outdoors: Basil.

“Basil really should wait to go out until nights are above 50,” he said.

There are so many kinds of tomato plants out there. Which kinds should I buy?

Seek out a variety of plants, Epstein said.

“Get some varieties that are disease resistant, and also throw in a couple of heirlooms,” he said. “The heirlooms are not as disease resistant. So if we did have a very damp summer where we had some disease moving through the area, the heirlooms tend to get the disease easier than some of the hybridized varieties which are not susceptible to things like welt and other bacterial diseases.”

Mix it up, he said. When planting, keep 30 to 36 inches between plants to promote airflow.

If all goes well, tomato plants will start bearing fruit later this summer.

“Generally, if you get your plants that are about a foot to maybe a foot and a half tall right now, you'll start to get some flowers here in early July,” he said. “You may get your first tomatoes mid to late July, depending on the variety. Most tomatoes come in late July through the month of August.”
