Around 2014 several fig trees were planted in the chicken yard. Some of the fig trees died and had to be replanted. The original ones, and the new ones have barely grown.
One of the original trees has barely put on any growth in four years.
In the past I had tried stuff like Miracle Grow plant spikes, and some Miracle Grow plant food. All that stuff is is a low grade fertilizer. Nothing I tried with Miracle Grow spikes or plant food helped the fig trees.
For 2018 I decided to try something different. I picked up some 6-7-7 fertilizer and put a cup around the base of each tree. This was done right before a rain. To benefit the plants the fertilizer has to be worked, or washed, into the soil.
