Summer Tomato Care

Follow our care tips to keep your tomatoes healthy and producing plenty of flavoursome fruit for summer salads and sandwiches, or to turn into sauce, chutney or jam!



  • To reduce the chance of blight and fungal diseases, avoid watering plant foliage.
  • Birds love juicy tomatoes – put up netting to protect yours.
  • Asparagus, basil, carrots, celery and parsley are ideal companion plants for tomatoes to help each other grow.
  • Tomatoes are also compatible with chives and onion.


  • Water regularly, a deep soaking two or three times a week is best. Irregular watering can lead to blossom end rot, and if plants dry out they are more susceptible to pests and diseases.
  • The best times to water are in the morning or evening rather than in the heat of the day.


  • As your tomatoes grow, remove the laterals to encourage bigger and better fruit. Laterals are the shoots that grow out from the side of the stem.
  • Prune the base leaves to let sun and light in to improve air circulation to help prevent fungal disease like blight.


  • Allow fruit to ripen on the plant. Although tomatoes do ripen further once picked, the flavour is always at its best when allowed to ripen fully on the plant. With sun, warmth and water your tomatoes will ripen soon enough!

Summer Tomato Care Comments

  • Hi, I planted a "Money maker" tomato plant in a container. It has fruited well but every tomato had a hard white core in the centre making them inedible. Why would that be please.

    • Hi Joy, this can be caused by inconsistent weather, hot then cold, and especially cooler nights, it is common in early spring and autumn when temperature fluctuations are common. Tui Seaweed Plant Tonic will help improve plant tolerance to temperature fluctuations and may help prevent this happening. Another reason is too much fertiliser, especially if the weather has been fluctuating hot and cold, always feed tomatoes as per fertiliser pack instructions. Some varieties, especially older varieties such as Money Maker are more susceptible to this happening as the pulp is more 'fleshy'. It is not so common with new tomato varieties. I hope this information is helpful.
