- Gardening gloves: These will protect your hands from thorns and sap.
Pruning Techniques for Japanese Holly Sky Pencil

When pruning Japanese Holly Sky Pencil, it’s essential to use the right techniques to avoid damaging the plant. Here are some tips to keep in mind:
Tip 1: Cut just above a growth node. This will help the plant to heal quickly and reduce the risk of disease or pest infestations.
Tip 2: Make clean cuts. Use sharp, clean tools to make precise cuts, and avoid tearing or ripping the plant’s tissues.
Tip 3: Prune in small increments. Remove small amounts of foliage at a time, stepping back to assess the plant’s shape and making adjustments as needed.
