Why is my Thuja browning at leaf tips?
Thuja needs regular watering and the soil needs to be moist (but not soggy) at all times. A plant that is under 3 years needs to be watered every other day for lush green foliage.
My thuja is growing too big, what do I do?
If not pruned, the Thuja will grow unchecked into a conical shape, but it loves a good pruning. Prune it at the end of summer, start of spring, or the end of August. While spring pruning (April) will increase growth, fall pruning (August) will slow down its growth for a while.
What are the pests that attack Thuja?
Although majorly pest free, it does get occasional scale, rust, or fire blight infestation that can be damaging.
