Tips for growing kale

Kale is a plant that likes cool climates and is extremely cold-resistant. It can tolerate short frosts, but it is also heat-resistant. When planting, it must be planted in sunny soil and the soil must be kept fertile. Kale grows fastest when the temperature is between 20 and 25 degrees.

Pest and disease control for kale

1. Aphids

Kale is a plant with strong vitality and is relatively simple to grow, but you must pay attention to the prevention and control of pests and diseases during the planting period, especially aphids, which have a particularly strong reproductive capacity and can reproduce many times a year. After these aphids appear, they can gather on the leaves and tender stems of kale and suck their juice. At this time, the best way to deal with it is to spray pesticides. Spraying 40% omethoate can significantly control pests and diseases.

2. Leaf roller

Leaf rollers, also known as leaf rollers, are one of the most common diseases of kale. After the disease occurs, the leaves of the kale will be rolled up with silk and hide inside to eat the leaves of the kale. To reduce the occurrence of this disease, all dead grass and fallen leaves in the planting site should be destroyed in winter, and the overwintering insects should be cleaned up as much as possible. When a large number of leaf rollers are found on the leaves of kale, it is also necessary to spray dichlorvos emulsion or phoxim emulsion in time.
