โ๏ธ Pruning Methods for Shape and Health
Pruning should occur in late winter or early spring before new growth emerges. Focus on removing dead or damaged branches and shaping the plant to achieve your desired form.
๐ณ Ongoing Care for Outdoor and Container Growth
For container growth, ensure adequate drainage and watch for rootbound conditions. In outdoor settings, apply mulch to retain moisture and suppress weeds, promoting a healthier plant environment.
