It can be frustrating when trees and shrubs fail to establish well. The main symptoms of poor establishment are yellow or brown leaves and shoots dying back. There are steps you can take to remedy the situation, but it is better to try and prevent these problems happening in the first place.
In most cases trees and shrubs will establish well, with no problems as long as root health, weather, soil conditions and the aftercare provided are favourable.
If one or more of these factors are unfavourable, trees and shrubs may fail to establish, often within the first two years after planting.
Although they may show some signs of growth, the foliage of trees and shrubs that are struggling to establish may begin to deteriorate, often in early summer, with leaves turning yellow or brown, shrivelling and falling. This can take place over several months or quite suddenly.
Although larger sized specimen trees and shrubs can be perfect for making instant impact or screening, they are naturally more prone to poor establishment. This is because the root system is invariably undersized compared to the amount of top growth. They will require greater aftercare than smaller plants, especially with attention to watering.
Expect it to take two or even three seasons for specimen trees and shrubs to be fully established.
