If you want to harvest plenty of asparagus, you must always keep an eye on the vegetables because the plant is susceptible to diseases and pests. But do not worry - you can protect your plants.Having your own asparagus in the garden is something very special. So you do not have to line up in the morning to get some fresh asparagus. And you are not exposed to the price increase. But own asparagus also means a lot of work, so you probably enjoy it very differently. Anyone who decides to grow asparagus, should always look at his perennials carefully, because he is threatened by many enemies. With optimal care and the right remedies, the asparagus quickly recovers and you can look forward to a lush harvest.
Common asparagus diseases and pests
In the case of diseases, especially the asparagus rust should be mentioned. This is a fungus in which the spores infest the asparagus and destroy the leaves. The leaves get first orange-red, then brown spots and then die from the shoots.
Asparagus rust can not be controlled by natural means. Here it only helps to reach for an effective fungicide (such as this one here). You can, however, prevent the asparagus rust by not placing the individual plants too close. Moisture on the leaves should always dry quickly, so an airy location is important.
Root rot is also a common asparagus disease. The cause is a fungus (Fusarium), which is present in every soil, but only strikes when the soil is permanently too moist. A loose, sandy soil and a good runoff prevent waterlogging, so that the root rot can not even arise.
Above ground you recognize the disease that the plants drive out very bad. The roots are black and rotted inside. The asparagus bushes then enter.
Root rot in asparagus is almost impossible to treat, the prevention of a well-ventilated soil is the only choice for hobby gardeners.
Typical asparagus pests
Especially with new plants one can observe the asparagus fly. She lays her eggs on the tips of young shoots from April onwards. The hatched larvae feed on the shoots, which then die quickly. Asparagus flies multiply massively, as antidote there are special pouring preparations (such as this one here). As a precaution, you can stretch fine-meshed nets over the asparagus bed. This is especially useful for green asparagus. White asparagus is protected by the mound or additional foil.
Asparagus beetle and asparagus chicken
Asparagus chickens have black wings with red edges, four or six white spots on the wings. The asparagus beetle is orange and has twelve black dots on its wings. Both beetles will be active from May and lay their larvae on the shoots. Endangered are especially the above-ground parts. Asparagus plants, which are protected by accumulated soil and foil, are hardly affected.
As a countermeasure usually only helps if you pick the pests. The beetles are easy to recognize. The faster you intervene, the better you prevent the beetles from multiplying and reappearing next year. Insect killers should not be used on edible vegetables in the garden.
