The page provides written and visual instructions on Growing Roma Tomatoes. The model we are using is the Sweet Mojo F1, pictured above.
Roma tomatoes are also called "grape" tomatoes and are delicious with a firm texture that makes them a fun snack.
Excellent, sweet-flavored fruits are like a smaller version of Red Grape. They are uniform in size, avg. 10 gm., have good texture, and resist cracking. Indeterminate. Good for greenhouse growing.
Days to Maturity: 59
GROWING ROMA TOMATOES AS SEEDLINGS: When growing Roma tomato seedlings, do not start too early! Root-bound, leggy plants that have open flowers or fruit when planted out may remain stunted and produce poorly! Sow in flats, using soilless peat-based mix 5-6 weeks before plants can be transplanted out after frost danger.
Keep temperature of the starting mix at 75-90°F; tomato seeds germinate very slowly in cooler soil. When first true leaves develop, transplant into plug trays or 3-4" pots for large, stocky 7-8 week transplants for earliest crops.
Grow seedlings at 60-70°F. Water only enough to keep the mix from drying. Fertilize with fish emulsion or a soluble complete fertilizer.
TRANSPLANTING OUTDOORS: Transplant growing Roma tomato seedlings into medium-rich garden or field soil 12-24" apart for determinate varieties, 24-36" apart for indeterminate, unstaked varieties, and 14-20" for staking. Water seedlings with a high-phosphate fertilizer solution.
For earliest crops, set plants out around the last frost date under floating row covers which will protect from frost to about 28°F. If possible, avoid setting out unprotected plants until night temperatures are over 45°F. Frost will cause severe damage!
FERTILIZER: Abundant soil phosphorus is important for early high yields. Too much nitrogen causes rampant growth and soft fruits susceptible to rot.
PRUNING And STAKING: Determinate (bush) varieties do not need pruning and may be grown with or without support; fruit ripens within a concentrated time period. Indeterminate (climbing) varieties should be staked, trellised, or caged, and pruned for best results; fruit ripens over an extended period.
DISEASES: Refer to a good Extension publication or Identifying Vegetable Diseases Book for help. Learn the common tomato diseases in your area. Select resistant varieties.
For disease prevention, use young, healthy transplants, avoid overhead irrigation, plow in tomato plant refuse in the fall, rotate crops, and do not handle tobacco or smoke before handling plants. Fungicides can reduce certain diseases when properly selected and applied.
BLOSSOM END ROT: Prevent it by providing abundant soil calcium and an even supply of soil moisture.
INSECT PESTS: Use rotenone to discourage flea beetles on seedlings. Tomato hornworms can be controlled with Dipel. Use BT for potato beetle larvae, and rotenone or pyrethrin for adults.
HARVEST: Fully vine-ripened fruit.
STORAGE: Store firm, ripe fruit 45-60°F for 4-7 days. Make salsa, ketchup or tomato paste from them.
Below is a picture of my growing Roma tomatoes. I started these plants inside several months ago thinking I would plant them out in August but it was too hot. So I had to babysit them longer than I had planned. I was able to plant them in early October. I planted these in a new Three Tiered Garden. I built this bed out of materials I had when I took down the two little greenhouses I had built last fall.
Below is a picture of our Sweet Mojo. It is progressing well. We did have a freeze but I covered it and sat up with it all night try to keep it alive with a camp fire.
I think it did okay.
