What do tomatoes and peppers need?
Both are warm-season crops that need full sun, warm soil, and a long season. They are usually started indoors and transplanted after frost danger has passed and soil has warmed. Cold nights can stall them even without frost.
Choose varieties for your season length, disease resistance, and use. Local trial results help, and so do tips from neighbors.
If your season is short, choose early maturing varieties and use plastic mulch or covers to warm soil. Ask local growers which varieties finish reliably before fall frost.
- Full sun and well drained soil
- Transplant after frost danger and warm soil
- Pick varieties suited to season length
- Look for disease resistance labels
How do I start and transplant them?
Start seeds indoors for several weeks and harden them off before planting. Tomatoes can often be planted deeper than they grew in the tray, which supports root growth, while peppers are usually set at their original level. Check extension guidance for your crop.
Water in well, and protect young plants from wind and cold with covers if needed.
Harden off seedlings carefully, since sun and wind can scorch tender leaves. A week of gradual exposure saves weeks of recovery.
How should I support and prune tomatoes?
Many tomatoes need support from stakes, cages, or trellises. Support keeps fruit off the ground, improves airflow, and eases harvest. Some varieties are determinate and ripen over a shorter period, while indeterminate types keep growing and need more support.
Pruning methods vary. Removing lower leaves and some suckers can improve airflow, but over-pruning can expose fruit to sunscald. Ask your extension office what works for your varieties.
Tie plants loosely so stems have room to grow, and check ties through the season. Soft ties, cloth strips, or clips reduce damage to stems.
How do I water and feed?
Even moisture is the key. Swings in water cause problems such as blossom end rot and cracking. Mulch and drip irrigation help keep moisture steady. Feed based on soil test results, since too much nitrogen can produce leaves at the expense of fruit.
Peppers are sensitive to waterlogging and cold, so ensure drainage and warm soil.
Blossom end rot is linked to uneven water, not usually a lack of calcium in the soil. A soil test and steady watering are the first steps, and your extension office can advise.
What problems are most common?
Early blight, late blight, leaf spots, wilts, hornworms, aphids, and blossom end rot affect these crops. Rotation, resistant varieties, mulch, airflow, and watering at the base lower risk. Remove diseased leaves promptly and clean up residue.
Late blight can spread quickly in wet weather, so report suspected cases to your extension office. Diagnosis comes before treatment.
Hornworms are large caterpillars that can strip a plant quickly. Check regularly and remove them by hand, and ask local experts about options if numbers are high.
- Rotate away from nightshade family crops
- Water at the base of plants
- Mulch to reduce soil splash
- Remove diseased material and clean up residue
When and how do I harvest?
Pick tomatoes when they have good color for the variety, and handle them gently. Peppers can be picked green or left to ripen to full color, depending on use and market. Frequent picking encourages production.
Do not refrigerate tomatoes if you want to keep flavor. Store each according to extension advice.
Handle peppers carefully if you grow hot types, wear gloves, and avoid touching eyes. Wash hands afterward, and keep hot peppers labeled and away from children.
- Pick tomatoes at good color
- Pick peppers green or ripe by market
- Wear gloves with hot peppers
- Pick often to encourage production
What do I do at season end?
Remove plant residue, clean up stakes and cages, and rotate to a different crop family next year. Save notes on varieties and problems. A cover crop can protect the soil over winter.
Frost ends the season for these crops, so watch forecasts from the National Weather Service and pick before a hard freeze.
Share extra produce with neighbors or a food pantry if you have more than you can sell. Ask the pantry about their handling and labeling preferences first.
- Remove plant residue
- Clean stakes and cages
- Plant a cover crop
- Write notes on varieties and problems
Key takeaways
- Start with warm soil, full sun, and well chosen varieties.
- Keep moisture even and support the plants.
- Rotation, airflow, and sanitation limit disease.
- Pick at the right stage and handle gently.
