To do what specifically Japon?

These are two very different fertilisers. Bonemeal has very little notrogen whilst chicken pellets are very high in nitrogen. Nitrogen is the fertiliser that promotes green leaves so is good for cabbages etc; for flowering plants you don't want lots of big leaves so you don't give nitrogen.

Thanks Bulb......Bonemeal it is then.

Hi, interesting Bulb, cos I wondered earlier - is it ok to put chicken pellets on shrubs which have flowered early (specifically chaenomeles, japonica or quince(!)growing in a pot) and are now producing their new leaves....
thank you, jeanette
