Planting Tips for Drought-Tolerant Trees
Selecting drought-tolerant trees is only part of the equation. Proper planting and care ensure your trees thrive, particularly in dry climates. Here are a few critical tips to get the most out of your investment:
- Choose the Right Location: Plant the trees in areas with well-draining soil. Avoid low-lying spots where water might accumulate.
- Watering: Even drought-tolerant trees need proper watering when first planted. Water deeply at the root zone and reduce frequency once the tree is established.
- Mulching: Apply a layer of mulch around the tree's base to retain moisture and protect roots from extreme temperatures.
- Pruning: Regular pruning helps maintain the tree’s shape and encourages healthy growth, particularly for species like Ficus Hillii.
- Fertilizing: Use a slow-release fertilizer that will provide consistent nutrients without promoting excessive growth, which can stress the tree in dry conditions.
