Thanks very much for your question. It is normal for the flowering stalks of Anigozanthos to turn brown and dry up towards the end of summer. The leaves, however, should still be green. If the whole plant has turned brown, it may be that it was over watered or in soil that did not drain well or that it was too dry. They also do not like fertilizer with Phosphorous. Here is a check list to keep the plants alive:
- Plant in a sunny location. If you live where there is frost, plant under the eave of a house or high tree canopy
- Give excellent drainage (lots of compost or sand/gravel)
- Where it is dry in the summer, they need regular water
- Do not feed heavily and avoid Phosphorous (middle number)
- After the flowers have died, remove the stalks and leaves to almost ground level. Each "fan" of leaves only flowers once. Be careful not to cut or damage new fans that are forming. These will flower next year.
I hope this helps. As always feel free to visit any of our stores for more expert advice!
