Ponderosa Red
Solanum lycopersicum
HOW TO GROW TOMATO
Start indoors 6–8 weeks before last frost, plant out 1–2 weeks after last frost. Requires bottom heat for good germination. Pot up to 3-4” pots when first true leaves develop, bury to first leaves. Gradually harden off in full sun 1–2 weeks before transplanting after last frost. Transplant out stocky 8 to 10” tall plants. Apply super phosphate for high early yields and to avoid blossom-end rot. Too much nitrogen causes excessive vegetation. If fruit cracks, reduce watering. Indeterminate varieties are trellised, fruit ripens over an extended period. Prune to one leader pinching suckers in leaf axles every 7 to 10 days. Thirty days before last frost prune leaders to ripen remaining fruit. Determinate or bush varieties do not need pruning or trellising. Soil pH 4.3-6.6. Hardiness zones 4. Annual.
