This is the first season ever that I let self sown Velvet Beans (Mucuna pruriens), a potent nitrogen fixer, grow all around my 13 year old avocado seedling.....and its growth suddenly has been very rapid! Until last season I grew veggies in 8 container gardens beneath it, but this year it grew SO much and put out so much shade nothing would grow in them! So I've begun sawing off the long horizontal side branches to re-admit sunlight so I can garden there again. Quite a thing to witness. John
