I've been having a hard time getting stuff to grow. Especially from seed. After about 15 to 20 experiments, only spring field peas took. (I tried about six kinds of clover, two kinds of vetch, peas in the fall, buckwheat, corn, beans ...) Usually, it gets about an inch tall and just sits there. A few days ago I saw a presentation on bamboo. The presenter was a consultant all over the world on planting all sorts of stuff. He showed us a slide of a site in Oregon where he planted a variety of things including bamboo and said that nothing would grow. It would just sit there. He said he had a soil test done and saw that the P levels were toxic. So he planted an alder tree next to each planting. The alder took off, sucked up heaps of P and then all the other plants took off. I have super high levels of both P and K. Is alder my only choice? Any suggestions on other things that might do the same thing?
