Summer feeding

Hungry plants need extra goodness

1 Once they are growing and flowering, edibles in growbags such as tomatoes, courgettes, squash etc need weekly feeding with high-potash tomato food.

2 Feed perennials, such as this echinacea, with a granular fertiliser as new growth comes through. Fork it in and water well.

3 Indoor plants are returning to growth now so need fortnightly feeding and more watering to help them get started.

4 Switch to a summer feed for citrus plants. It will have high level of nitrogen that is essential for strong growth and healthy leaves. Remember that it is still too early to move lemon trees back outside.
