Are you helping to look after a local street tree? Below, we’ll cover everything you need to know about street tree watering.
Why does watering NEW treeS matter?
As temperatures rise over spring and summer, and the air is drier, regular watering is crucial for newly planted street trees.
During their early years, street trees face many challenges adapting to their urban environment. Sufficient water during this period will help them to grow strong.
Local councils do their very best to water newly planted trees, but many can’t support the level of watering they really need. This means that new trees run the risk of dying during very dry spells, or simply not developing anywhere near their full potential.

How much water does MY TREE need?
Young street trees need a minimum of 50 litres of water weekly to thrive, and even more during dry summers.
What we ask of you, is simply that you top them up with a couple of watering cans full every week. A standard watering can hold around 5 litres of water, so if you can manage a couple every week, it will really make a difference.
What can I use to water my tree?
Repurposed containers
You don’t have to have a watering can to water the tree. Street trees are happy to drink from plastic bottles, buckets or whatever container you have on hand. Opting for reused plastic bottles keeps a tree hydrated and helps the environment!
Making the most of greywater
Did you know you can use greywater from your washing up, baths and showers to water trees? While you can get very technical and set up diverter valves on your drainpipes, there’s an easy way to start. Just save the water from your dishwashing and use it to give your tree a drink – no need for anything fancy!
Using a hose
Hoses, while sometimes controversial and subject to restrictions during water shortages, can be a practical option for watering street trees. What’s more, as you can control the flow of water you can minimise water waste.
During hot or dry spells, hosepipe bans may be enforced so we recommend checking with your water provider to see if your area is affected.

How do I water my tree?
If the tree has a watering tube
If your tree is fitted with a watering tube, pour half the water down the tube, and the other half around the tree trunk.
Here’s Tom from our parent charity, Trees for Cities, demonstrating how to water a tree with a tube:
If the tree has a watering bag
The tree may be fitted with a watering bag. It will feature slits near the top, often located under a label, for pouring water. This double-lined bag retains water and releases it gradually.
Also, it’s a good idea to water the area around the tree’s base.
If the tree has no accessories
Simply water around the trunk slowly. Ensure that whatever amount you give the tree can soak away within 10 minutes to avoid leaving puddles behind.
tree watering dos and don’ts
- Do water at the right time: Water in the morning or evening, when it’s cooler, to maximise absorption of water before it evaporates in the sun.
- Do water efficiently: If the tree has a watering pipe, pour half of the water down the pipe and the other half on the ground around the tree trunk. If the tree has a watering bag, simply fill that. There is a small slit near the top as the bag is double lined, and it will gradually release the water – giving the soil time to soak up.
- Do build a routine: Get into the habit of regular watering. Join in on our #WateringWednesday campaign, or water on a particular day of your choosing. Consistency is the key.
- Don’t rush watering: If watering all at once, take your time and allow the tree to absorb the water slowly, ensuring effective hydration and preventing runoff.
