Beautiful lilies! Over 600 different varieties compete to make your garden a whole lot more gorgeous. Some of them were cultivated as ornamental plants thousands of years ago. Lilies not only beautify the garden, but also the living room as cut flowers - and in every color your mood demands.
Lilies are available in pink, pink, yellow, green, red or blue, one-year or perennial. Precisely for the perennial lilies in the garden, one of the prerequisites for a magnificent development is that you recognize and combat pests before they can multiply overwhelmingly. Even with lilies in the room, pest control is of course important:
Caring Lilies - Are you missing something?
- If your lilies do not want to develop in your favor, first check the culture conditions. Location and soil conditions, water permeability and hydration, too much or too little fertilizer - make sure you have focused in every detail on what lilies need.
- If your lily should actually feel comfortable under the given conditions, but the opposite is the case, then only an infestation with pests or an illness remains the cause.
Persistent and feared: the lily chicken
Probably the most widespread pest of the lilies is the lily chicken, a beetle with a botanical name Lilioceris liliiwho, with his bright red color of just under one centimeter in size, will have noticed you instantly if he has colonized your lilies. The beetle itself has only moderate appetite, its larvae are all the more voracious for it. You should therefore prevent any increase of the lily chicken as possible. Which will not be easy, the conscientious beetles devote themselves very zealously to their reproduction - you would not be the first gardener to suffer a perpetual fit of laughter when a fiercely copulating couple of lilac chickens revolted outraged at the underside of their leaves. In a single summer, such hardworking mating can develop three to four generations of lily chickens.
To prevent this from happening, you should first collect every lily chicken you see by hand. You can not fall for a popular beetle trick: The lily chickens can easily fall when threatened, often under the utterance of an angry chirping, then remain lying on the ground lifeless and can not be found through her black belly. Not with you: just place a bowl of a fairly large diameter under the plant when hunting. So no beetles fall to the ground. You either collect the camouflaged specimens on the potting soil by putting the whole thing in very bright light, or you sweep the top layer of earth into the bowl with a folded piece of paper.
Fight lily chicken
Actually, it is about removing the larvae from the lilies - in the room as completely as possible, in the garden at least to a degree that prevents your garden from becoming the Mecca of all lily chickens in Germany. From the orange-red to dark brown appearing larvae, which camouflage themselves with a thick layer of their own faeces, under this camouflage layer they develop an irrepressible appetite and cause even in small numbers and in a short time a Kahlfraß. Therefore, you should regularly check your plants between April and September for feeding marks and remove the eggs immediately. Any break could take revenge immediately. Other ways to control the larvae:
- You can make it easier to collect by rinsing the larvae on the garden lilies with a powerful jet of water. They depend on lilies but are unable to find their way back to them.
- It should also help if you spray the lilies with a tansy extract or wormwood tea, in case of very strong infestation, it is also recommended to rinse the leaves with a solution of soft soap and spirit.
- A solution of one percent neem oil in water should help, as well as the incorporation of Neemschrot in the garden soil. However, one hears recently more and more doubts about the safety of neem. Also, Neem quickly becomes ineffective if stored poorly.
- The next idea would be to sprinkle coffee grounds around the plant, which has already displaced some lilies, but others liked it very much...
Natural antidotes: rock flour or fritillaria
Another possibility: You could dust the underside of the sheet with rock flour, also called rock salt. It is finely ground basalt. It should really help, if the beetles are not completely distributed, they should be able to reduce it to a residual level of about 10%.The finely ground rock flour is not easy to apply, especially since it goes to the bottom of the leaf. You could use the rock flour z. B. fill in a nylon stocking and tap lightly against the underside of leaves, it should dust enough of the rock flour.
The downside of all these treatments is that they have to be repeated after each rainfall, if they are to work (and should be used multiple times without rain).
If all of this is too much effort for the liberation of your garden lilies, you could then plant the lily chickens even their favorite plant among the lily plants, a fritillarie. For example, an imperial crown, but also with any other chess flower one should be able to distract the lily chickens successfully. At their disadvantage: Although the Fritillaria attract the lily chickens especially, they should also have no chance these plants to pupate, because they dry out before.
By the way, chemical control is not a promising way for the lily chickens: the lily chickens do not react to most of the usual insect repellents. Effective should be agents that contain as active ingredients pyrethrins, a natural substance from the chrysanthemum. However, they would have to be injected several times in such a way that the eggs or larvae are moistened, which is difficult at the latest when the larvae are submerged in their coats.
Other lily pests and diseases
Other pests that could visit their visible lilies include thrips and aphids. Both are combated with the remedies commonly recommended against these pests. If the buds are malformed, usually Lilyminier flies are responsible, this year's flowering is then beyond saving. However, you should then discard all buds in the trash, so the infestation in the next year set certain limits.
If your lilies are damaged at the roots, in addition to feeding damage caused by garden snails and voles, an infestation with roundworms (nematodes) or with fungi comes into consideration. Especially the Fusarium mushroom and the gray mold blight endanger lilies and are usually recognized only when the leaf tips turn yellow or brownish spotted. The fight against fungi on garden plants is possible, but requires a planned approach.
But that would be even better than if the stains on the leaves or on the creepy foliage viruses were responsible, which would unfortunately only give you the choice to burn the crops incurred and to strive for virus-resistant varieties. Thankfully, the breeders of these wonderful flowers have developed many varieties that viruses can not harm.
