If the drainage is poor then grevilleas can quickly suffer from root rot diseases, like phytophthora. Typically the grevillea will look thirsty with leaves quickly turning brown and usually clinging to the branches. Extra watering doesn’t fix the problem and the plant usually dies in a short period of time.
Can you prune a grevillea?
