Maintenance Tips for Rock Gardens
- Watering: Most rock garden plants are drought-tolerant, but it is important to water them regularly during their establishment phase. After becoming established, they usually require minimal watering. Check the moisture level of the soil before watering.
- Weeding: Keep weeds at bay to prevent them from competing with your rock garden plants for nutrients and water. Regularly inspect the garden and remove any unwanted plants or grass.
- Pruning and Deadheading: Some plants benefit from regular pruning to maintain their shape and appearance. Deadheading, the removal of faded flowers, encourages new blooms and prevents seed production.
- Soil Preparation: Before planting, ensure that your soil is well-drained and free from excess organic matter. Mixing in coarse sand or small gravel can improve drainage in heavy clay or compacted soils.
- Fertilizing: Most rock garden plants do not require regular fertilization. However, you can use a slow-release fertilizer during the growing season to provide essential nutrients.
