A few trees became a nuisance with volunteers growing in huge amounts under them. I may not have planted them if I had known this.
Fairchild #2 canistel... I miss a lot of drops and the seeds quickly establish themselves in the mulched understory. The fruit is worth keeping the tree as is my Julie seedling "Juicy Lucy" whose seeds erupt into seedlings easily in mulch.
I've pulled Coffee due to the hundreds of seedlings it produced, and my lemon drop mangosteen is on the list to go.
Any other noteworthy trees which need a lot of seedling removal work?
