The old olive tree, in the South Bed, is just not thriving. It seems not to like neither the cold nor the heat. The other two olive trees are doing much better, growing bigger and faster.
So I took it out. We considered this possibility when we were excavating the south bed.
I dug down and took out the rock that was under it.
and then filled it back in with dirt and compost. The drip irrigation system in this area needed to be repaired.
and then 5 bags of mulch on top of the area to cut down on the weeds and evaporation.
