It is important to follow the manufacturer’s recommendations regarding application rates and timing to prevent over-fertilization.

4. Soil

One of the key attributes of creeping juniper is its adaptability to various soil types, including sandy, loamy, and rocky soils. Well-draining soil is essential to prevent waterlogged conditions, which can be detrimental to the plant’s health. Additionally, the soil pH should ideally range from slightly acidic to neutral. If your soil is excessively compacted or poorly draining, consider amending it with organic matter or perlite to improve its texture and drainage properties.

5. Pruning

Pruning is generally minimal for creeping juniper, as the plant naturally maintains its low, spreading habit. However, periodic pruning can help remove any dead or damaged foliage, promote air circulation, and maintain the desired shape and size. This can be done in early spring before the new growth emerges. It is crucial to use sharp, clean pruning tools to minimize the risk of disease transmission and to make precise, clean cuts.

6. Propagation

Creeping juniper can be propagated through various methods, including semi-hardwood cuttings, layering, and seed propagation. Semi-hardwood cuttings are typically taken in late summer to early autumn, while layering involves encouraging a lower branch to root while still attached to the parent plant. Seed propagation, while possible, may result in variability in the offspring and is less commonly practiced for this particular cultivar.

7. Container Popularity

Due to its low-growing and spreading nature, creeping juniper is well-suited for container cultivation, particularly in raised beds, containers, and rock gardens. When grown in containers, it is critical to ensure proper drainage to prevent waterlogging, as well as to provide adequate sunlight and airflow to promote healthy growth.
