Late summer tomato care

The older tomato plants get, the more likely it is that they will start to suffer from foliar diseases such as leaf spots and blights. Left untreated, diseases can weaken plants and cause significant damage. While plants are still laden with ripening fruit, diseases should be controlled to keep plants healthy and promote a good harvest. Yates® Liquid Copper Fungicide is a handy, broad spectrum fungicide that will help control tomato diseases such as leaf spots and blights. For best disease control, spray both the upper and lower surfaces of leaves.

Whitefly are tiny tap sucking insects that congregate in large numbers underneath tomato foliage and fly up into a cloud when disturbed. Due to their large numbers, whitefly can quickly deplete tomato plants, reducing vigour and tomato yields. Whitefly can be controlled with Yates Nature’s Way Vegie & Herb Spray, which is an insecticidal soap. They key to effective whitefly control is persistence and a degree of stealth! Minimise disturbing the whiteflies before spraying and spray both sides of foliage every 5 – 7 days. Spraying underneath leaves is important as that is where whiteflies predominantly hide.

Keeping soil moist during summer can be a challenge, but it’s especially important for tomatoes. Tomatoes are prone to a condition called blossom end rot, which causes a sunken, decaying area on the end of the fruit. It’s caused by lack of access to regular water and calcium. Two ways to help prevent tomato blossom end rot are to keep soil consistently moist during the growing season and applying some Yates® Hydrangea Pinking Liquid Lime & Dolomite to the soil. It is a concentrated source of calcium which can help reduce the chances of blossom end rot. Don’t be put off by the product name – it’s fine for tomatoes!

Tropical tomato time

Tropical and sub-tropical gardeners can continue to sow new crops of tomatoes during late summer, for harvest in late autumn and winter. Cherry tomatoes are bite sized and flavour packed and several varieties are great for growing in small spaces and pots. They’re also perfect for the vegie patch.

Yates® Tomato ‘Patio’ " produces delicious and richly flavoured small round fruit that weigh around 100 g each. It’s a compact variety that doesn’t require staking and is quick to grow, with fruit maturing after around 10 weeks from sowing.

Growing compact varieties of tomatoes in pots couldn’t be easier:

To protect tomatoes from the most common pests and diseases, lightly dust Yates Tomato & Vegetable Dust over the plants every week.
