Brown spots on the rock pear - what to do?
If there is brown discoloration on the foliage of a rock pear well before the beginning of autumn, this can be due to different problem situations. The possible triggers range from extreme climatic conditions to insufficient soil conditions to annoying fungal diseases.
On brown leaf margins, the weather could well be responsible
If the leaves of the rock pear first show their brown spots from the leaf margins with a gradual spread to the inside of the leaf, then it could well be an early leaf release of the plant due to extreme weather conditions. Although pear trees are generally very easy to care for, extreme heat and dry phases can already result in certain foliage discolourations in a hot summer. If the phenomena occur immediately after transplanting a pear, it could also be a wrongly chosen time of planting or a different problem in the planting action. As a rule, then there is no great cause for concern and the robust plant forms new leaves without further measures in the spring.
Continued issues may indicate site defects
If a rock pear repeatedly shows brown spots on the leaves over several growing seasons, first of all possible location and soil problems should be eliminated. Rock pear need a sunny location and a well-drained soil without waterlogging for healthy growth. In particular, waterlogging in clusters of pears in the pot can be a problem, so the following measures should be taken as a precaution:
Growth deficiencies of a rock pear can sometimes be explained by a too small planter and justified by the associated formation of rotation roots.
Brown spots due to fungal diseases
It is not at all so rare that brown spots on the leaves of a rock pear are symptom of a fungal disease. After all, different varieties of the rock pear may well be victims of pear grid or other diseases. As a precaution the trees can be treated with broadband fungicides. But you can also provide with targeted cutting measures for improved ventilation of the treetop and should remove strong infested branches as soon as possible.
Tips
The pear should not be planted in the immediate vicinity of juniper, as these two plant varieties can easily infect each other with diseases.
