Product Description:

70 days. Richly pigmented tomatoes often have equally complex flavors, and that’s definitely the case for Darkstar. This gorgeous beefsteak boasts large, pleated fruit with the look and flavor of an heirloom but the uniformity, disease resistance, and yield of a modern hybrid. The squat tomatoes reach 2-2 ¼ inches tall by 3-3 ¼ inches across with a deep, purple/red cast inside and out. Vigorous, productive plants are resistant to Late Blight, so you’ll be harvesting from the indeterminate vines early and continuously through the end of the season. HR: LB, V.

Fantastic Tomato!

I was a first year gardener last year and started with these and some other types of tomatoes. I live in NW WA state (Zone 5b) and started these with peat plugs March 30 indoors under pro grade grow lights and heating pads at 77-79F. Ended up with 96% germination rate. (I planted way too many expecting some mortality). While some other "hardy" types died off completely, these ended up being the "star" tomato of my summer! Heirloom flavor and looks, and easily the hardiest and best producing of my first garden. While some others like the early cherry tomato died and died and did not flourish until transplanted to the garden soil, these just took off trucking and never slowed down. Mind you... I did best practices and kept transplanting onto larger pots to keep from root-bounding them. We had cold spring and I did not get them planted until Memorial Day weekend. Some were nearly 2' tall and had fruit started. These made me feel like a Master Gardener, though some of the others humbled that feeling down and they did poorly. Taste? Marvelous! I will have Darkstars in may future gardens until I die!

Lycopersicon lycopersicum The first ripe, juicy tomato of summer is a delicious milestone of the season for gardeners. Each year we test and evaluate more than 250 tomato varieties to bring you the most flavorful, best performing selections, for every desired use.

Days to maturity are calculated from date of transplant.

Determinate tomatoes: grow compactly, sprawling laterally, usually do not require staking, and fruit ripens over a short period of time
Indeterminate tomatoes: grow on long vines, generally require pruning to 1 or 2 leaders that need to be trellised
• Fertile, well-drained raised beds covered with plastic mulch promote early growth and better yields
• Tomatoes are high feeders and will benefit from regular fertilization with Age Old Bloom
• To prevent blossom end rot use a high calcium amendment
• Overwatering can cause fruit to crack

Direct Sowing
• Not recommended

• Sow seeds in trays 6-8 weeks before anticipated transplant date; up-pot into 3-4 inch pots when the first set of true leaves appears
• Strong light and cooler temperatures (60-70°F) prevent plants from getting leggy
• Fertilize with Age Old Grow every 10-14 days
• When transplanting work in compost, 1/2 cup of TSC's Complete fertilizer, and handful of bone meal
• Determinates can be spaced 18-24 inches apart, indeterminates 24-36 inches apart
• Tomatoes can be buried up to the top 2 sets of leaves
• Use Kozy-Coats or Victorian Bell Cloches to protect young plants

Insects & Diseases
Common insects: Flea beetles and tomato hornworms
Insect control: Pyrethrin or row cover for flea beetles, and Monterey B.t. for tomato hornworms
Common diseases: Early and late blight
