Follow these helpful tips from our in-house horticulturalists to give your garden the best chance to flourish this summer. 

NettingTo maximise your crop, cover fruiting trees, such as peach, nectarine and apricot trees. Try to do this before fruit starts to colour. To prevent birds pecking fruit from the outside the net, consider creating a frame for the net to drape over.  

Pick up fruitTo prevent pests and disease in your garden, pick up all fruit that falls, including tomatoes and other vegetable fruit. Put this fruit through a worm farm or hot compost system or feed them to your poultry (only as much as they can eat) - or your green organics kerbside collection bin. Fruit provides a food source and breeding ground for earwigs and provides ideal conditions for fungal conditions like brown rot. 

Shade some vegetablesSome vegetables, such as capsicum and tomatoes, benefit from shading during the hottest months of summer. Ensure good air movement to prevent diseases. 

Tomato yellowingIf your tomatoes are yellowing from the top down, you may have a tomato wilt issue. Remove affected plants. If it is yellowing from the bottom up, you may have tomato russet mite, which are invisible to the naked eye. Remove infected plants. Organic pesticides will kill mites, but unfortunately beneficial insects. Try planting daisy plants among your vegetables to attract insects that feed on the mites. Friendly insects include lace wings, lady bugs, hover flies and parasitic wasps.  

Watering -In the height of summer, most vegetables will need to be watered at least once a day and often twice a day as the plants get larger and the temperatures get hotter. Where possible, water the stem and roots of the plant, not the leaves, to prevent some diseases. Mulching around plants will help to reduce evaporation and suppress weeds.  

Powdery mildewLook out for powdery mildew, a powdery white coating on leaves and stems, which can weaken your plants. Give your plants lots of air circulation to help prevent powdery mildew on plants like cucumbers and zucchini. Milk sprayed on plants in full sunlight might also help.  

Summer pruningPrune peach and nectarine trees as soon as they have finished fruiting. The new growth after pruning will bear next year’s fruit.
