conferance pear tree just developed a brown rash on lower leaves any suggestions or cures chris



Potash or magnesium shortage might cause leaves to go brown. Epsom salts for magnesium deficiency. Diluted and watered in. Nitrogen shortage yellow/brown, iron more yellow. Growmore scattered and forked in may help. Repeat in springtime. Look at what you have in shed by way of fertiliser. Look at formula and follow instructions (save buying any more) Local chemist may have epsom salts.
