Leaves at young pear have reddened, and outside at all not September, but July? If not to take measure for rescue of tree, it can dry up and die. It is important to define why leaves at pear redden in the summer. It can be connected with various reasons – from the shortage of fertilizers before invasion of wreckers.
Reason 1. In the soil on which pear grows, there is not enough phosphorus.
Reddening of leaves of fruit tree begins with scape, it uneven, besides foliage is twisted? It happens at deficiency of phosphorus. At the same time newly minted escapes weak, leaflets on them narrow, in the lower part of branch they can fall down.
What should I do? In the middle of the next spring make fertilizing of pear phosphoric fertilizers. For example, spray foliage with means "Ammophos". Repeat the procedure till July each 2-3 weeks.
Reason 2. In hole where the tree is planted, there is too much lime.
The surplus of lime leads to lack of iron, therefore, of impossibility of further development of chlorophyll plants. As result – red leaves at pear.
What should I do? Around krone dig through small ditch (two dozen centimeters in depth), bring humus or compost, well water and fill up with the soil. With organic fertilizers, especially manure, do not overdo – it is possible to burn pear roots!
Reason 3. The earth is too damp.
Soil overwetting becomes often simple answer to question why on pear leaves redden in the summer. Tree roots at the same time badly breathe, the plant is constantly oppressed. It happens if:
- close underground waters lie;
- the garden is in the lowland;
- the site is boggy.
What should I do?
You need to fight against moisture surplus as pear of it does not take out at all! Dig out grooves for drainage. Also bulk bed around trunk can help. If underground waters are too close to surface and your methods of drainage of the soil do not help, solve problem cardinally – replace young pear to the sublime place.
Reason 4. Pear is too deeply planted.
If the tree is strongly buried, roots begin to start to rot, the sokodvizheniye is broken and foliage reddens. Experienced gardeners plant pear to root neck (not to confuse with the place of inoculation!), differently bark begins to decay.
What should I do? The young plant needs to be dug round from all directions and to lift with earth lump. Keep in mind: the top layer of the earth can raise further - you will bring humus and compost under tree, to cover the soil mulchy. Never excessively bury some pear!
Reason 5. Pear has ached, is struck by wreckers.
Usually about disease of fruit-tree the fact that the sheet plate becomes covered by red spots signals, but not completely changes color. Most often the reasons of defeat of pear – plant louses and ticks.
What should I do? If the cause of illness is unknown, at the beginning of garden season before blossoming process tree universal remedies, such as "Azofos", "Is fast"; after infructescence it is possible to use Tersel, Delan, the same "Is fast".
Tick tell red-brown, convex specks on foliage about defeat of pear. To get rid of tick, before blossoming, then in July use such means of fight against garden wreckers as Omite, "Masai". Attentively read the instruction on packing.
Red, time of cherry color, the pear leaves which are displaced from top to bottom in the form of rollers speak about defeat of plant gallic plant louse. In emergency process tree such means as Fufanon, Inta-vir, Aktara, Fitoverm, Konfidor, strictly following instructions. It is necessary to do it only 2-3 times, it is obligatory at least in three weeks prior to harvesting.
Try not to allow tree infections any more! Preventive measures:
- put away all garbage in the fall from garden where the wrecker can settle;
- even before swelling of kidneys process tree modern means from insects ("Kinmix", Agravertin, etc.);
- regularly mow and remove grass between beds;
- put celery, fennel in garden - they will attract natural exterminators of plant louse, such as ladybug and lacewings.
Reason 6. The stock and scion are incompatible.
At pear leaves redden, and bark on the place of inoculation peephole swims away? Most likely, there was serious trouble – the stock and scion were not combined. It happens if the planting stock was low-quality, the inexperienced gardener was engaged in inoculation.
What should I do? In most cases the tree with incompatible scion and stock should be grubbed out. Replace it. Choose saplings on seed stock. If from sunflower seed dichka to receive plant and to impart to it branch of any grade, the compatibility will be ideal.
Take saplings on clonal stock (from shank) only in farms with the checked reputation. There inspection of compatibility of stock and any given grade of fruit-tree has to be carried out with guarantee.
If you have correctly defined why leaves at pear redden, at least in the next season it will please you with abundant blossoming and fructification.
