Vigorous quinces thrive in the right location. With practical preventative measures, infestations of leaf blast, flesh blast and fire blight can often be prevented. We'll show you how to easily implement them in your own garden.
flesh tan
At first glance, this disease is not recognizable. However, when the fruit is cut open, it reveals itself. Brown spots run through the entire flesh. The causes of this metabolic disease are strongly fluctuating weather conditions or a late harvest.
Prevent:
Harvest the fruit as soon as it turns yellowish. It is also advisable to examine the quinces for any impairments throughout the ripening period. To do this, cut open one picked fruit completely. There is no effective way to combat the disease.
Care mistakes:
Browning also occurs when the lime content of the soil is very low. High nitrogen levels can also be a cause.
leaf tan
This disease is also known as quince rust. A stubborn fungal infestation becomes visible through damage to the quince leaves. They get small, dark spots and die early. The damp weather is described as the main cause.
The resistant fungal spores overwinter on the ground. For this reason, old leaves must be removed immediately with household waste. In addition, in the following year after the last frosts, a clearing cut should be in order. This ensures effective ventilation of the crown. The leaves dry off quickly. The fungus cannot spread.
Warning: fire blight
This disease is probably one of the most dangerous variants. Immediate action is necessary. This will prevent it from spreading in other ways. The quince tree is removed from the garden. Dispose of the wood with the regular household waste. Under no circumstances should the remains of the diseased tree be put on the compost.
Important:
Fire blight is notifiable.
tips and tricks
You should watch out for small pests. In general, the quince is very robust against this. In the case of a severe infestation, the use of small livestock, such as the Asian ladybird, can be useful.
