Cherry Tomato in August: monthly care

Cherry tomatoes don't require pruning in the traditional sense, but regular attention from June through August will improve yields and plant health. The approach depends on whether your variety is indeterminate (cordon) or determinate (bush). Most cherry tomatoes are indeterminate, producing side shoots in the leaf axils where branches meet the main stem. These side shoots, or "suckers," should be pinched out weekly while still small and soft—simply snap them off with your fingers. Removing them channels the plant's energy into the main stem and fruiting trusses rather than excessive leafy growth. Work through the plant systematically from bottom to top, checking every leaf joint. If a side shoot has grown large and woody, use clean secateurs to avoid tearing the stem. In late July or early August, pinch out the growing tip of indeterminate varieties (the very top of the main stem) once four or five fruit trusses have formed. This practice, called "stopping," encourages the plant to ripen existing fruit before autumn rather than producing more flowers that won't mature in time. Also remove any yellowing or diseased lower leaves throughout the season to improve air flow and reduce the spread of blight. Determinate bush varieties need far less intervention—just remove obviously damaged foliage and let them grow naturally. Avoid over-pruning any variety, as leaves are needed for photosynthesis and to shade developing fruit from scorching. Always work on dry days to minimise the risk of spreading fungal spores, and wash your hands between plants if blight is present in your area.

Cherry tomatoes need consistent watering to prevent problems like blossom end rot and split fruit. Water deeply two to three times per week during dry weather, aiming for the soil rather than the foliage to reduce fungal disease risk. Container-grown plants dry out faster and may need daily watering in hot spells. Erratic watering—allowing the soil to dry out then flooding it—causes fruit to crack, so aim for steady, even moisture throughout the growing season. Begin feeding in May once the first flowers appear. Use a high-potash liquid tomato fertiliser (the type sold for flowering plants and tomatoes) every seven to ten days through May, June, and July, following the label instructions. High-potash feeds promote flowering and fruiting; avoid high-nitrogen fertilisers, which encourage leafy growth at the expense of fruit. Stop feeding once fruiting slows in late summer. Cherry tomatoes are not winter-hardy (zone 10a–11b) and will be killed by the first autumn frost. In temperate Europe they're grown as annuals; pull up and compost plants in October once cropping finishes, but do not compost any foliage showing signs of blight—bin or burn it instead. The main disease threat is tomato blight (Phytophthora infestans), especially in warm, humid weather from July onwards. Watch for brown patches on leaves and stems; remove affected growth immediately and consider a preventative copper-based spray in high-risk years. Glasshouse whitefly and aphids can also be troublesome under cover; use biological controls or insecticidal soap. Refresh mulch mid-season to maintain moisture levels and suppress weeds.
