My inga,the last one left ,looks chlorotic,grows a leaf then dies,then grows another leaf and it always have just a single not too well developed leaf.
I moved it to a bigger pot made from a bucket to see if she makes a come back.
The guamuchil thogh ,grows soo well that i started to trim them to form the crown.No fertiliser needed for them.
The mimosa tree outdoor grew 2 meters in a season ( 6 foot) after i fed her somme cow manure.
The cow manure its actually nitrogen negative if its dry.Instead of adding nitrogen to the soil it actually depletes the soil a little of nitrogen because its needed to getting decomposed.Just like wood chips so i either use verry fresh cow manure,diluted or i add nitrogen to it if its dry.
Dry one should be perfect for nitrogen fixers because it lacks nitrogen.
