Tomatoes

Follow the recommendations in this Tech Sheet for best results with germination of 'Maxifort,’ an interspecific tomato cross — the product of traditional plant breeding crosses between a domesticated tomato parent and a wild tomato parent. To improve germination rate and uniformity, we recommend careful consideration of the measures we have outlined here.

We encourage you to try these resurrected open-pollinated, heirloom and heritage tomatoes and let us know what you discover. We appreciate hearing from you, so we developed this downloadable, printable Survey Form for Our Open-Pollinated Tomato Project, so growers of these 3 varieties can enter observations and send us your feedback — or simply retain for your own records.

A downloadable, printable PDF version of our article on the most common tomato pathological and physiological issues. While relatively easy to grow with regular maintenance, tomatoes are not without production challenges — especially from the realm of pests and diseases. Here is an overview of common disease, pests, and physiological problems encountered when growing tomatoes.

This Tech Sheet provides instructions for pruning and string-trellising of greenhouse or hoophouse tomatoes, from Johnny's Selected Seeds.

Trellising plants, such as tomatoes and peppers, eliminates fruit-to-soil contact, improves plant health, and can increase marketable yields. Higher-quality and easier-to-pick fruit translates into increased grower profits in the marketplace. The most common crops that basket-weave trellising is used for are tomatoes and peppers. Trellised plants remain upright, are easier to irrigate and harvest, and allow for more effective coverage should spraying become necessary. Trellising also promotes better air circulation that lowers humidity, allowing for more rapid drying following dew, showers, irrigation, or application of sprays...

Follow the detailed instructions in this Tech Sheet to reap all the benefits of side-grafting: overcome disease and production-related issues, improve overall crop health, reduce or eliminate pesticide use, lengthen harvest duration, and significantly increase net income. The entire process from sowing of rootstock and scion varieties to final transplanting of grafted plants into greenhouse soil or soilless medium normally takes 6-8 weeks. The major advantage of side grafting is that this method is more forgiving of differing stem diameters than top grafting...

Follow the detailed instructions in this Tech Sheet to graft desirable fruiting tomato varieties to vigorous, disease-resistant tomato rootstocks as a cost-effective method for overcoming disease and production-related issues; improving overall crop health; reducing or eliminating the need for pesticide use; lengthening harvest duration; and significantly increasing net income. The entire process from sowing of rootstock and scion varieties to final transplanting of grafted plants into greenhouse soil or soilless media normally takes 6-8 weeks.
