The first three years
To avoid accidental damage, make sure to communicate to all those involved in maintaining the space are aware of the trees you have lovingly planted.
Watering is one of the most important things to ensure successful establishment after planting a tree. Whips planted will require little additional watering, however the bigger the tree planted the more watering is required. Be mindful that newly planted trees do need watering, even if it has been raining!
A newly planted tree should be watered when planted in the autumn or winter, at the point of bud burst in the spring and should be watered throughout the spring and summer until the leaves have fallen in autumn.
During summertime, newly planted trees should be watered at least 2-3 times a week with at least a full watering can. Watering is advised for the first 2 summers after planting, after this the tree should be able to get enough water from the surrounding soil.
Where possible use a watering can with a rose attachment on the end or another method that will administer water slowly and at a low pressure, mimicking rainfall. If regular watering using this method is not possible, tree watering bags can be purchased from many nurseries which help by releasing water slowly.
