JAPANESE TRIFELE BLACK

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 ½–3 inches long and wide and are very crack resistant. Indeterminate, potato-leafed plants.

Awesome Tomato

These were in pleasant surprise. I bought one start at a local nursery in the Sacramento Valley area. When all my other tomatoes were done, these still had a lot of tomatoes. After harvesting everything late summer-early fall, they produced a second flush of green tomatoes, which I thought would never ripen, but they eventually did, and we got close to a dozen in Nov and are still picking now in December, and they are delicious. Awesome!

needs warmth

Wonderful flavor, but only after mid-Sept. here. Huge producer, very healthy plants, picking tomatoes now, in mid-November. We have cool foggy coastal conditions, can see ocean, so that's probably why flavor was blah at first. Now they're delicious. Absolutely gorgeous tomatoes.

Japanese Black Trefele a winner in Olympic Peninsula Greenhouse

First to fruit, last to succumb to cold in our hard walled greenhouse in zone 7. Unfussy and has an interesting triangular shape. Stored some (October!) to ripen in a cool room and enjoyed them on Jan 3. Eat when quite ripe for best flavor.
Joins Sungold, Black Cherry, Cherokee, and Stupice on the annual grow list for the greenhouse at Shooting Star Farm. Didn't produce as much outdoors. Quite similar in all aspects to Stupice (another potato leafed type) but more flavorful and interesting.
A winner!

New Favorite

I grew these for the first time this year. They are my new favorite. My plant produced lots of large sweet fruits!! They have a lovely taste. I live in California zone 9a. They grew perfectly in this area.

Days to maturity are calculated from date of transplant.

Culture
• 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

Transplanting
• 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
• Disease prevention: A strict 3-4 year rotation, remove vines at the end of the year, fungicide

Harvest & Storage
• Harvest when fully ripe, do not refrigerate for best flavor
• Green fruit should be ripened in a cool, dark area; make sure fruit are not touching
