Thanks to special breeding juniper is very robust and less susceptible to diseases. Some fungi and various pests can still trouble the needle plant.
The juniper is probably one of the most popular coniferous plants in many hobby gardens in this country. The plant is generally considered to be quite robust and not particularly susceptible to disease, as there are now special breeds. These make many pests and diseases nothing or only little. Nevertheless, a fungal attack can be a problem, for example.
Which pests and diseases in the juniper may be expected and what you can do about it, we will reveal in detail below.
Brown shoot tips at juniper
Even though some hobby gardeners might think that one's own juniper is ill because the tips of the shoots turn brown, that's usually not the case. Rather, it is often not a sign of disease, but is an indication of a lack of light. Thus, this problem is relatively easily remedied by simply transferring the juniper to another location where it gets enough light.
Only if it is an older juniper, this move would be a problem. Because an older plant is unfortunately following the implementation frequently. Then it is necessary to eliminate the lack of light in other ways, which may mean, for example, the pruning of a tree or other plants in the vicinity of the Juniper.
A fungal infection can also be a problem with the juniper, since it is, as already mentioned, a needle plant. However, those who want to stop the fungus, should not only remove the affected areas of the plant. Rather, it also lends itself to the use of a corresponding pesticide from the specialized trade. The choice of an agent on a purely biological basis is to be preferred. Other diseases that can affect the juniper include these diseases:
- Juniper blister rust
The instinctual dying is also due to harmful fungi and therefore to treat in the manner already mentioned. The juniper blast rust, however, it comes to thickening of shoots, which are already woody and very dry. These bubbles have a gelatinous texture and a rusty red color. They form especially in spring. The juniper blast rust is also called pear rust.
Proceed against the juniper blast grate
This disease can cause quite a lot of damage, as the juniper loses its leaves early. If the plant is affected several times by the juniper blast rust, it noticeably weakens it. To prevent this from happening, prophylactic measures make sense. From the moment the leaves begin to sprout, spray with the horsetail extract is recommended. Potash-based fertilizers especially for leaves can also be used for prevention.
If the juniper is already infected with the pear grid, the control should take place immediately during the infestation, ie in the time when the very prominent spore bubbles develop. If only a few branches are affected, they are simply cut back so far, until only healthy wood remains. Plant protection products can also be used.
However, if the leaves already discolor with conspicuous dots as a result of the pear grid, this measure is of no use. However, those who prefer not to be annoyed with the problem of the pear grid can also opt for varieties in which no or only very rarely such an infestation can be assumed.
Pest infestation at juniper
Not only diseases, but also pests pose a threat to the juniper. In this context, the following pests should be mentioned in particular:
- Tree or bark louse
- juniper leaf miner
- Juniper Deckelschildlaus
In a lice infestation, the pests suck the juniper. This can cause the needles and shoots of the plant in the worst case die completely. If it is an infestation with the Juniper lobster, this can also lead to a needle discoloration. The more the lice suck the juniper, the more the plant is inhibited in its growth.
However, the so-called Juniper Moth is the most common pest problem. This is a small butterfly that is only about five millimeters long and indeed reminiscent of a moth. For the caterpillars of the pest, the juniper is a found eating dar. The damaging effect is mainly because the larvae of Juniper Mining Moth work their way from one shoot to another and thereby lead to a dying of the respective shoot tips.
To prevent moth infestation, all home gardeners should resort to special insecticides approved for this purpose. This is especially important to spray when the moths have their flight time. In autumn and summer, it can also be very useful if the shoot tips, which are already affected, are simply cut off. But you should make sure that you monitor the health of the Juniper as closely as possible in order to intervene in time.
Even with a lice infestation pesticides are only helpful if they are used as early as possible. Already with an incipient infestation you should intervene therefore in any case. If the needles of the juniper have already noticeably discolored, it is already too late anyway. Sprays can then be confidently refrained, as they can no longer achieve an effect at a late date.
