Description

85 days. Lemon-yellow fruits blush red on the bottom and boast a robust flavor with a perfect combo of sweet and tart. A winner of our 2017 Harvest Festival heirloom tasting - Mike says this is his favorite yellow tomato! Listed in the 1915 catalog of Isbell’s & Co of Jackson, Michigan just 30 miles from our Dexter farm. Plants are vigorous, so be sure the plants get tied to something sturdy. Fruits vary in shape and size from medium to large. Flesh holds together well for sandwiches, salads, and is good cooked as well. There are occasional red fruits. Common to older tomato types, fruit cracks easily so don’t leave it on the vine too long. Indeterminate. Seeds grown by Nature & Nurture Seeds.

Growing

Growing Instructions (for USDA zone 5b):

Start tomato seeds inside at least 6 weeks before last frost (around 4/1). Ideal temperature for germination is 85°  (use a heating mat). Days to germination: 5-14. Once leaves appear, grow plants at 72°. Plant seedlings outside late May into fertile garden soil (with lots of compost or decomposed manure) at a spacing of 18” apart. Stake tomato plants. Tomatoes are susceptible to several fungal diseases (including Early and Late Blight and Verticillium Wilt). To prevent blight, keep foliage dry by 1) Pruning tomato plants to allow for good air circulation 2) Water with drip irrigation/soaker hoses. Crop rotation is also key to preventing tomato diseases. Ideally, plant tomato plants in a spot that has not had any Solanaceae crops (tomato, peppers, eggplant, potatoes) growing there for 4 years. Frequent watering will help to minimize cracking of tomatoes.

Harvest:

Harvest when fruit are yellow with a red blush on the bottom, and when fruit is somewhat soft when squeezed.

Seed Saving Instructions (for gardeners):

Tomatoes are relatively easy seed-saving crops. They are primarily self-pollinated but may be crossed pollinated by insects when different tomato varieties are planted next to one another. You can just save seed and see what you get! Isolation distance of 10ft will minimize crossing while 150’ is necessary to eliminate it. Always harvest seed from the best plants. It is best, but not totally necessary, to collect seeds from a minimum of 6 plants. Collect ripe tomatoes and cut and squeeze out seeds. See instructions for fermenting seeds. Rinse and dry seeds on a screen or wax paper.
