Growing Cherry Tomato in a pot

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.
