How do you control Scale on Grass Trees?
We have an Australian Grass tree which has been infested with what appears to be scale. The tree is in its original pot when purchased and then that placed in a larger pot and elevated allowing for plenty of drainage from both pots.
Scale pests are common on Grass Trees. Spray with Yates Nature's Way Citrus & Ornamental Spray at least once a week until the last sign of the pest has gone. Some of the dead Scales may still remain on the plant, these can just be wiped off with a rag.
Feeding your Grass Tree with Yates Dynamic Lifter Liquid Concentrate will also help with pest and disease resistance and resiliency.
