Rising temperatures and dry spells are leading to an increasing loss of new street trees, but the nation can do its bit urges tree groups.

The Arboricultural Association is joining forces with the Woodland Trust and local authority tree officer associations to rally the UK public to water their new street trees using recycled rainwater or grey water, such as washing up water. 

According to the Met Office 2022 was the warmest on record and the UK's total rainfall persistently below average for the year creating challenging conditions for newly planted and younger trees to thrive.

Catherine Nuttgens, head of the Woodland Trust's urban tree programme, explained: "Trees are crucial to our well being by cooling our towns and cities and improving air quality so we need to not only plant more but look after those we already have."

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

John Parker, chief executive of the Arboricultural Association added: "Planting a tree is just the start of the story. The health and survival of new urban trees is threatened by increasingly dry weather. It is recommended that newly planted trees are given 50 litres of water per week during the summer months, for the first three years. You can help ensure healthy trees for the future over the summer months by watering trees near you."

Since setting up the annual watering campaign in 2020, the Arboricultural Association has brought on board an ever expanding list of groups to take up the challenge.

To help spread the message wider, the Woodland Trust has this year come onboard. 

Catherine Nuttgens concluded: "The challenging conditions presented by living in more built up environments means trees in our streets and urban areas need a bit more TLC . It's a fun job to do with the kids or make it a post tea time routine to water the trees . It can rally community spirit too if estates or streets club together."

Watering should ideally be carried out in the early morning or evening.

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.
