You can fertilize your tree right after root pruning, but it's largely a useless thing to do. The roots aren't going to be using most, if any, of the fertilizer right after the root pruning operation. It will take at least a couple of week before the plant's damaged roots will be able to use fertilizer. However, if the tree wasn't root pruned that drastically and there smaller feeder roots left, fertilizing could help push things along.

I would recommend that you don't fertilize a newly root pruned and potted tree for at least 4 weeks. Then commence fertilizing starting with a weak solution of liquid balanced fertilizer progressively increasing to a normal feeding regime that is appropriate for the tree.
Spirit_Helper: - I give my newly potted trees a weak solution of Seasol (liquid seaweed extract) straight after transplanting the tree. Seasol contains little or no nitrogen but is loaded with trace elements and stimulates root growth.

You can read what W. Pall thinks of not fertilizing a tree after cutting its roots on his blog
BTW, there are scientific studies that show that fertilizing a tree after rempotting actually improves the speed at which new roots are formed.

G'day Stephen...
You tell us "...don't fertilize a newly root pruned and potted tree for at least 4 weeks..". Then, less than 3 lines later, you tell us "...I give my newly potted trees a weak solution of Seasol (liquid seaweed extract) straight after transplanting...loaded with trace elements...". Don't? Or is it DO? Is Seasol fertilizer? Or not? Trace elements...? I find that I have 12 or 16 trace elements in the fertilizer that I have been using for more than ten years. I'm confused. Pat

Pat,
I can see were my post could confuss some readers. Seasol is not a fertilizer so to speak. It contains very little NKP but is very rich in most trace elements. It acts as a stimulant to plant growth, especially root development. I find it very benefical to my trees to given them a dose of a weak solution immediately after repotting. here is an extract from the Seasol site: http://www.seasol.com.au "Seasol is a dynamic growth stimulant and plant tonic, it is not by definition a fertiliser. Seasol contains plant growth regulators (auxins and cytokinins) which have a profound effect on the vegetative and reproductive capacity of the plant. In other words, Seasol promotes growth by stimulating the plant on a hormonal level, rather than by providing nutrients as a fertiliser does."

Vit. B 1
I have heard that Vitamin B1 is almost essential in transplanting, repotting and root prunning. I have not heard of anyone using it much on this forum. Has anyone had tremendous success with it?

What importance a title
|
Mark,
I use B1 when transplanting and occasionally as a drench on stressed trees. I use to buy super thrive and gave up on it do to its cost and outrageous claims. I did dilute the fact that it had B1 and that I could obtain that ingredient elsewhere for much cheaper. I crush 6 tablets up to a fine powder and mix it with a gallon of warm water. You know if you got it right as the aroma is a kin to Superthrive. Use the same soaking procedure you would for any other transplant soak.

Many people say not to fertilize after repotting. Walter Pall says that's a myth, at least in the spring. My impression is that strong chemical fertilizer could be harmful, but how about mild soluble or granular organic fertilizers? Are there good studies that support one or the other of these positions?
