Fertilising potted plum tree

Ii have a 4 year old Victoria plumtree,  it has always been in a very tall tub. I have purchased a top dressing fertiliser, how much do I need for pot.

    Fertilisers come in all different strengths so it's impossible to give you an accurate answer without knowing exactly what you have bought.  There should be instructions on the pack though - don't be tempted to exceed the stated dose as you can easily do more harm than good. 

    If it is fish, blood and bone, that is quite forgiving and I would sprinkle about an ounce (25g) onto a large pot of the type typically used for trees and gently work it into the surface.  Adding 2-3 cm of compost on top would do no harm, either.

    If the dosage instructions are for an amount per square metre, dividing that by 3 or 4 would likely be about right.


    A trowel in the hand is worth a thousand lost under a bush.
