As the plants are a diverse group, there are a wide range of conditions that they will grow under. The following generalized statements regarding the cultivation of grevilleas would apply to a majority of the plants in cultivation. Grevilleas flower best in sunny, dry locations although they will also grow in light shade. Plant in well-draining soil and be very careful of any fertilizers applied to these plants; many Grevillea, especially Western Australian species, are highly sensitive to phosphorus and the use of fertilizers high in this element can be fatal to these plants. They also do not like excessive watering and garden water tolerance or ability to grow near lawns will be exceptions rather than the rule. Regular pruning after flowering is recommended to enhance and rejuvenate flowering and plant growth. Most varieties are drought tolerant, as well as frost hardy down to 20 º F.
