Video Guide

Arboricultural Association Technical Director John Parker runs over some important basic young tree maintenance.

Watering young trees in dry weather
Please Water Me

Newly-planted trees need to be watered regularly over the summer months if they are going to become established and thrive.

If you have a tree outside your house, or one that you pass on your daily walk, then you can help.

Requirements vary depending on a number of factors such as species and location, but a general rule is that they should receive at least 50 litres of water per week in May, June, July and August:

Please water regularly during dry periods with as much as you can – Every little helps

Watering should ideally be carried out in the early morning or evening.
It is good practice to water trees for the first three years after planting.
Where possible, water should be sustainably sourced. Harvested rainwater is ideal, but bath water, or water which has been used for the washing up, is also suitable.
If the tree has a watering pipe, then half of the water should be poured down the pipe and the other half on the surface of the tree. If the tree has a watering bag, then fill that.

More information about tree watering can be found in the London Tree Officers Association (LTOA) publication Sustainable water management, available for free download at

Reporting Pests & Diseases

Learn how to report signs of dangerous tree pests and diseases.

Cases of ill health found in trees across the UK and Ireland should be reported through:

For the UK the Forestry Commission’s TreeAlert which can be found at:

In Ireland and Northern Ireland use TreeCheck which can be found at:

There are many invertebrates like mites and nematodes, bacteria, phytoplasmas, water molds, plants (mistletoes) and viruses that can cause damage and need to be avoided through biosecurity measures.
