Japanese Black Trifele Tomato (Heirloom 70-80 Days)

$ 2.95

The Japanese Black Trifele is a highly productive Russian heirloom. Brick-red, 4-6 oz pear-shaped fruit rarely seen in other potato leaf varieties. Every summer we share our tomato trials with the staff for a taste test.  The Japanese Black Trifele was the favorite for 2019. They loved the dense, smooth texture and clean taste, a natural balance between sweet and tangy. Don’t let the gangly structure of this plant fool you.  The Japanese Black Trifele is a workhorse for tomato production. 

20 seeds



Solanum lycopersicum


Germination: 7-14 days

Germination Temperature: Optimum soil temperatures 70-85ºF.

Seed Sowing Depth: 1/4” deep

Starting Indoors: 6 weeks before the last frost. Provide 75-80ºF soil temperatures. Sow 2-3 seeds per cell/pot, thin to the strongest seedling, or use the 20 Row seedling flat, transplanting into individual pots when seedlings get their 3rd set of leaves. Fertilize the seedlings every 7-10 days with a liquid or water-soluble fertilizer, diluted to ¼ of the suggested measurement. Transplant out after the last frost. Space 24-36" apart

Sowing Outdoors: Only in areas with very long growing seasons. Sow after the last frost. 

Harvest: When fruit is red (or the color of the variety planted) and firm.

Tips: The Japanese Black Trifele should be panted in fertile soil, amended with compost, mulch, and provide even moisture. Plant deeper than they were growing in the containers as it makes a stronger roots system. Apply a light compost tea every few weeks. Do not apply excessive nitrogen, which can promote excessive foliage and poor fruit set.
