Photinia pruning

Question: Photinia pruning

Hi 4days ago I pruned the photinias (put in winter and well developed they were 80cm high) I left them with three branches as big as a finger at 30cm only with the leaves without new branches ... now the leaves seem to dry out and I don't see new gems ... I didn't dry up ??? I'm giving him water to start them but I'm terrified that they won't leave anymore ... thanks in advance.

Answer: Photinia pruning

Dear John,
photinias are very vigorous evergreen shrubs, which usually respond quite well to pruning; these should be practiced after flowering, which occurs at the beginning of spring, in order to guarantee a denser and more compact development of the shrub, to make it grow round and not messy; after this more drastic pruning, you can actually practice other prunings, during the spring and summer months, but it is important that minor interventions remain, or the plant will not be able to quickly replace the hair you have removed, and will suffer very. The prunings made in spring give the best answers, faster and more luxuriant, because the plant is in full vegetative growth; Drastic pruning can also be done at the end of summer, when the plants begin to vegetate again after the summer drought and heat. When we prune a shrub very much, in order to favor the development of new more dense and dense branches, it is important that the plant is able to quickly replace the leaves we have cut, with new shoots, because the plants feed on chlorophyll photosynthesis; it is clear that if we have a large shrub, with a very wide crown, and we take most of the vegetation from it, the plant will temporarily have problems in keeping alive, as its photosynthetic capacity will be very small. By practicing the heaviest prunings in early spring, we know from the outset that the new shoots will appear over the course of a few days, and therefore the plant will remain "without food" for very little time. The drastic pruning carried out in the middle of June, on the other hand, risks causing the plant to suffer greatly, having just flowered and produced new leaves; For this reason it is clear that plants are now suffering a lot. The fact that even the leaves are drying up simply means that you have really pruned too much, practically removing all the foliage, and therefore the leaves, and therefore the plant's ability to produce sugars and "eat". Usually the photinias are able to recover even from this type of maltreatment, but if you have really pruned a lot it can also be that you have completely compromised them. Now it is important that you guarantee an unexceptionable cultivation, with watering to be provided only when the soil is well dry; avoid making other stress reasons, such as excess water or drought. Only when you notice the first shoots you can think of spreading slow release granular fertilizer at the feet of the plants.
