I regularly add Osmocote slow release fertiliser and I water with Powerfeed and Seasol every other week. But I often wonder how much difference these products make.
So I decided to do a little experiment with 4 Japanese Maple seedlings, to test the impact of these products.
From left to right:
Seasol, Slow Release, Control, Powerfeed.
All 4 trees came from the same seed and germinated at the same time. They are all in the same size pot and have the same soil (approximately 60%/40% organic to inorganic).
The trees are all roughly the same size except the Control plant has a few more leaves, so has a bit of a head start.
I will water all plants daily and at least once a week I will apply Seasol and Powerfeed to the appropriate trees.
The Slow Release tree has a good layer of Slow Release fertiliser on the surface of the pot and 2 fertiliser baskets, which I will keep topped up.
The control will just get water.
I'll report back every few months.
