Tomato Care: From Transplant to Harvest
Tomatoes are the most popular garden crop for good reason — nothing compares to a sun-warmed, vine-ripened tomato. But they need consistent care to reach their full potential. Here is your complete mid-season guide.
Pruning Suckers
Indeterminate (vining) tomatoes produce suckers — side shoots that grow from the joint between the main stem and a branch. Remove suckers below the first flower cluster to direct energy into fruit production. Above the first cluster, you can leave some suckers for more fruit or remove them for larger individual tomatoes.
Staking and Support
- Stakes: Simple and effective for indeterminate varieties. Tie stems loosely with soft twine as they grow.
- Cages: Less work than staking. Commercial cages are often too small — make your own from concrete reinforcing wire for heavy-producing varieties.
- String trellis: Popular in greenhouses. Twist the main stem around a vertical string as it grows.
Watering Tomatoes
Water deeply and consistently — 1-2 inches per week. Inconsistent watering causes blossom end rot (a calcium uptake issue, not a calcium deficiency) and fruit cracking. Always water at the base, never overhead. Mulch heavily to maintain even soil moisture.
Feeding
Tomatoes are heavy feeders. Side-dress with compost or apply an organic tomato fertilizer every 3-4 weeks once fruit begins to set. Avoid high-nitrogen fertilizers — they produce lush foliage at the expense of fruit. Look for fertilizers with higher phosphorus and potassium.
Common Problems
Remove the lowest leaves once they yellow — this improves air circulation and reduces blight risk. If you see dark spots on leaf tips, it may be early blight — remove affected leaves immediately and keep foliage dry.
