How to Plant Black Krim Tomatoes


Black Krim tomatoes are an heirloom variety that originated near the Black Sea, north of Turkey and west of Russia. It's a rather rare, mahogany-colored tomato that has gained popularity in recent years among gardeners who want to keep old-fashioned vegetables alive by growing them at their homes. The fruits are 3 to four 4 inches wide, and their taste is said to be "intense" and salty. It's a determinate tomato, meaning its vines won't ramble all over the place, and it produces fruit in mid-summer.

Step 1

Start seeds in a nursery flat indoors six weeks before your final spring frost. Fill it with standard potting soil and make holes a half-inch deep, 2 inches apart. Drop one seed into each hole and then cover with soil.

Step 2

Water well and put your flat in a protected area that receives full sun. If necessary, hang a fluorescent shop light above your flat and leave it on for 12 hours every day.

Step 3

Transplant seedlings to individual 3- or 4-inch pots when they are 1 to 2 inches tall. Fill your small pots with potting soil, water them well, then make holes large enough to accommodate the roots of your seedlings. Gently prick out each seedling and set one into each small pot.

Step 4

Firm the soil around the base of the seedlings and water well. Keep your newly transplanted Krim tomatoes protected from hot sun for two to three days, but be sure to give them partial sun or artificial light.

Step 5

Plant your black Krim tomatoes in their permanent location in your garden when they are about 6 inches tall and after your final spring frost. Add compost and a little peat moss into the planting area, then dig holes slightly larger than your tomatoes' roots, leaving at least 3 feet between holes.

Step 6

Set your plants into the holes and firm the soil around their base. If you create a slightly indented basin and then dig your planting hole in the center, you'll be able to flood the plant when you water it, which tomatoes like.

Step 7

Stake or otherwise support your young tomato plants to help keep them from dragging on the ground.

Step 8

Water your new plantings well; when you water them in the future, flood the area once a week. Cut back on watering after plants begin to form flowers and fruit---you can wait until they begin to droop before you water them again.
