This is obviously a species specific feeding regime I am emulating from Bonsai Focus.
Instead of 0-10-10 I am going to use the earth juice bloom 0-3-1 with every watering.
Instead of a kelp meal,I am going to use Earthjuice Catalyst .03-.01-.10 weekly,which has a bit of nitrogen.
I can use a rather strong application of both fertilizers if needed.
Both fertilizers have kelp,especially the Catalyst.
Will add micro nutrients too.
I will give a couple shots of quarter strength 20-20-20 while the tree is beginning to leaf to start the tree in the right direction,which may seem counter productive with some species,but Zelkova always have very short internodes at base of stem during first flush no matter how much you fertilize.
So,I am going to test this approach.
Will defoliate at least once,maybe not so much as last year(three times).I hope to have less shoot growth with this feeding regime to maintain much smaller Zelkova and more compact trees,really no rush.
