Watering, Watering, Watering!!! Climate on trees

Climate on trees
Our climate is changing, evident in wetter winters and drier summers. The effect of this climate on trees means that February saw the UK's wettest month on record, followed by a March with rainfall reduced to 47% of the average, and May with only 6.7mm compared to a long-term average of 52.8mm.
This shifting climate significantly impacts trees, particularly during dry summers. Even trees planted two years ago struggle without regular watering.
Watering is crucial for tree establishment and root system development. Many overlook the need to water newly planted or transplanted trees, assuming it's unnecessary, perhaps due to their size.
Our trees are sold with root balls, resulting in smaller root systems than those found naturally. Coupled with the changing climate's effect, this hampers their ability to absorb adequate water from the ground, necessitating regular watering even after rainfall.
Tree roots are delicate and take several years to reach full size. Therefore, regular watering is vital during the initial years after planting to ensure survival.
How to water:
To retain water around the tree's base, create a rim of soil approximately 20cm tall. This allows for thorough soaking with a hosepipe, preventing water runoff and ensuring absorption into the tree's roots.
