Planting and Care Tips for Coastal Windbreak Trees
Creating an effective coastal windbreak involves more than just selecting the right trees. Proper planting and care ensure your trees thrive and provide maximum protection. Here are a few tips to help you get started:
Planting Tips:
- Spacing: Ensure adequate spacing between trees to allow for healthy growth. For Cupressus leylandii 'Better Green', space them around 2-3 meters apart. For wider trees like Banksia integrifolia and Waterhousia floribunda, space them around 3-4 meters apart to avoid overcrowding.
- Soil Preparation: Coastal soils are often sandy or lacking in nutrients. Amend the soil with organic matter such as compost to improve its structure and water retention.
- Wind Protection: While your windbreak trees are established, consider providing temporary wind protection, such as windbreak netting, to shield young trees from strong gusts.
- Mulching: To retain moisture and suppress weeds, mulch around the base of the trees. An ideal layer of 5-7cm of organic mulch is perfect.
Care Tips:
- Watering: Ensure regular watering, especially during the first few years of establishment. Coastal conditions can be drying, so consistent moisture is essential for growth.
- Pruning: For trees like Cupressus leylandii 'Better Green', periodic pruning is recommended to maintain a neat shape and encourage dense growth.
- Fertilizing: In spring, apply a balanced, slow-release fertilizer to promote healthy growth. Be cautious not to over-fertilize, particularly in sandy soils.
