Why are the leaves on my grevillea are turning yellow on the tips and then going brown and dying

They aren't growing or flowering very much either.

Hi Judy,

Grevilleas like free draining soil and prefer a low pH. You may need to test the soil and alter the pH if required. If too much fertiliser is applied the plant tends to push it to the ends of the leaves. Have you applied fertiliser recently? There also may be an imbalance in the trace elements. Is the soil clayey? Add some compost to try and improve the soil. If sections of the grevillea die back Anti Rot can be applied to help stop root rot developing.
