Phosphorus and Grevilleas
| | |
Posted by nada1712 Costa Blanca, Spain (My Page) on Fri, Aug 28, 09 at 9:07
I keep hearing/reading not to use phosphorus on Grevilleas but I am told to use Fish Blood and Bone or Blood and Bone on them. Both of these have phosphorus? I am confused.
Can somebody enlighten me please |

| Not sure about the fish blood but blood and bone release nutrients slowly inlucing phosphorous hence why you get away with it. Depending on what plants you have I question how necessary it is to apply fertiliser anyway. |

I would not choose fish blood. Some people use blood and bone, but a very small quantity only.
In Australia we can buy special fertiliser for native plants, with low phosphorus. Fertiliser for lawns is also low in phosphorus, but it is very strong, so use only a VERY little.
As Danili says, it might be better not to use fertiliser at all. Grevilleas grow naturally on very poor soil here, and it is easy to kill them with fertiliser.
Cheers,
