Tomato Growing Guide: From Planting to Harvest
Nothing beats a sun-ripened tomato straight from the vine. With a spot that gets eight hours of summer sun, you can grow your own—it just takes a little planning.
Choose Your Growing Method
Containers
If your sunny space is a driveway, patio, or deck, use containers. A pot roughly the size of a six-gallon bucket with drainage holes works well. Use high-quality potting mix (garden soil won't drain well and may rot roots). Self-watering containers save time and let roots draw moisture as needed. For containers and small spaces, choose compact, patio, or determinate varieties.
In-Ground
Ensure well-drained soil amended with organic matter (compost or shredded leaves). A nearby water source is essential. Most vegetables prefer slightly acidic pH; test your soil before planting. Contact your county USDA Cooperative Extension Service for testing info and amendments.
Tomato Terminology
- Determinate: Plants stop growing at a set height; fruits ripen all at once. Compact, less staking needed—ideal for containers.
- Indeterminate: Vines grow all season, yielding more. Need stakes, cages, or mulch to keep fruit off soil.
- "Ripens 70 days from transplant": Fruit ready ~70 days after planting in ground or container.
Selecting Varieties
- For containers: look for "compact," "patio," or "determinate." Large containers with sturdy stakes can support indeterminate types.
- Match variety to use: slicers for sandwiches, paste types for sauce, cherries for salads, heirlooms for old-fashioned flavor (less disease-resistant but tastier).
- Start small—first-timers often overbuy. Expand next year as you gain experience.
- Add herbs—they're perfect kitchen companions. A favorite summer salad: basil, tomatoes, mozzarella, olive oil.
Planting Steps
- Timing: Plant 2–3 weeks after last frost when soil is warm and nights stay above 50°F (Memorial Day weekend in New England; adjust for your area).
- Harden off: If plants came from a greenhouse, give them a few hours of bright sun daily for several days.
- Deep planting: Bury all but 4–5 inches of stem; more roots will form along the buried portion. Trench-plant leggy seedlings sideways. Pinch off leaves on the buried section. Warm surface soil stimulates growth.
- Spacing: Allow ~3 feet between plants for air circulation (prevents disease, aids pollination).
- Fertilize at planting: Use balanced fertilizer, fish emulsion, or organic fertilizer per label. Fertilize again when flowering starts—only twice total. Excess fertilizer yields foliage, not fruit.
- Calcium boost: Add a handful of powdered lime to soil or potting mix to help prevent blossom-end rot.
- Cutworm protection: Cut the bottom out of a paper cup, slit the side, and circle it around the base, sinking the edge into soil.
- Water and stake: Water thoroughly. Insert stake now if using one, avoiding root damage.
Ongoing Care for a Bountiful Crop
- Tying: Use soft twine or fabric strips in figure-eight loops around stem and support; allow slack for stem growth.
- Watering: Water when soil is dry 1 inch down; don't keep soggy. Ensure good drainage. Reduce watering as fruit ripens—excess dilutes flavor and causes splitting. Pick ripe fruit before heavy rain to prevent cracking.
- Mulch: In-ground plants benefit from mulch to retain moisture and suppress weeds.
- Pest watch: Tomato hornworm caterpillars are ugly but obvious—check under leaves. For chipmunks/squirrels, try Hot Pepper Wax (also good for insects).
Bottom line: Have fun. Gardening is a journey with lessons from Mother Nature. Ask neighbors, share experiences, and try again if things aren't perfect.
