Remove tomato suckers to keep growth focused on fruit
Why it matters
Suckers are side shoots that grow in the leaf axil, the V between a leaf stem and the main stem. On vining tomatoes they grow fast and pull energy away from the fruit. Removing them keeps air moving through the plant and makes disease easier to spot.
Where it applies, and where it does not
Indeterminate, vining tomatoes, in any growing system. Not determinate, bush tomatoes: they fruit on all their stems, so removing suckers lowers the harvest. Check your variety first. A card that knows when NOT to apply to your plant is worth more than one that always says yes.
How specific it gets
Specific enough to act on without a second opinion: pinch anything shorter than one inch between thumb and index finger, right against the main stem, leaving no stub. Cut anything longer with sterilized snips, close to the stem without nicking it, and wipe the blades before the next plant.
The five steps, each with its own photograph
- Find the suckers: scan the main stem bottom to top, they sit in the leaf axils at about 45 degreesStep 1
- Choose the one sucker to keep, or none, depending on your height and spacingStep 2
- Pinch the small ones, cut the larger ones, sterilizing between plantsSteps 3 and 4
- Clear every removed sucker away from the plants, and wash your handsStep 5
