- Browning – leaves turning brown and fall off
- Undersized leaves – leaves that are smaller than usual
- Limited shoot growth – the tree does not show much sign of growth in the summer
- Wilted leaves – leaves are small and shrivelled
- Upward rolling of leaves – leaves curl upwards and start to look cylindrical
- Scorching – leaves look like they have been burnt by the sun
Prevent stress by watering young trees correctly
Give your trees a good soak
You want your young trees to develop a strong, deep root system that anchors them firmly and enables them to access deeper water reserves from the soil. Try to avoid frequent light watering as this encourages the formation of a shallow root system and makes the trees less drought resistant. Just don’t let the soil dry out completely because then it becomes harder for the water to soak deeply into the soil. As soon as the tree shows signs of stress, increase the frequency of watering.
Too much of a good thing can be a bad thing for young trees. Overwatering your trees can be as damaging as underwatering, so if your trees are not wilting and show no signs of drought stress, then they are getting enough water. Remember that even when the top of the soil dries out, the ground below the surface can still contain moisture.
