Japanese Trifele Black Tomato

Japanese Trifele Black Tomato


80-85 days. A truly transcendent tomato. Pear-shaped fruit has green-streaked shoulders, deepening to a burnished mahogany and finally to a darkened, nearly black base. The meaty interior has similar, opulent shades and an incomparable, complex and rich flavor to match. The fruit reach 2 1/2-3 inches long and wide and are very crack-resistant. Despite the name, this thoroughbred has its origins in Russia. Indeterminate, potato-leafed plants.
Also available as a plant.

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 calcuim 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

The rich flavor in the description is not an exaggeration. A mid-late season tomato, but worth the wait. Make sure you plant an early variety as well. I did not have any problems with the fruit cracking, probably because I used drip irrigation on a timer.

I love these tomatoes for several reasons. First, the rich color is beautiful when mixed into canning batches. Second, though we live in a cold area with lots of blight, these tomatoes keep producing long past the time that other tomatoes have succumbed to the cold nights and late blight.

Both my mom and I grew Japanese Black this year and were fans! First off I'd like to mention I had over 90% germination in less than lab conditions! The fruit was uniform and did not crack. We loved the taste! Certainly will reorder for the coming season!
Slightly disappointed

This was the first year I ever grew graft tomatoes; I bought the Japanese Trifele and the STriped Roman. I loved the Striped Roman. The Japanese Trifele were a little troublesome. Very vigorous vine, but the fruit itself inevitably cracked, leading to throwing away the top portion of nearly each tomato. The flavor is terrific, but I could not solve the crack problem.
