For those who want to learn how to control pests and diseases that affect citrus trees, Bigastro is organising a 12 hour course.
The course for 25 students will be run by professionals from the Valencian Institute of Agricultural Research and will take place between the 23rd and 26th April in the Municipal Auditorium Francisco Grau - 7pm until 10 o’clock.
I would like to know why my lemon trees have yellow leaves in winter and why they only produce a small crop of fruit. However with only two trees and with insufficient Spanish to understand all that is being said, I’ll probably have to look elsewhere for an answer.
Actually, a friend of mine did point me in the right direction last year. He noticed that my trees were surrounded by limestone chippings and explained that lemon trees are not lime tolerant.
His solution was to remove the chippings and to feed the trees with some acidic material. He suggested collecting vegetable waste and old tea bags, let them rot well down and then spread the mix around the base of the trees.
A further suggestion was to add sulphur to the soil because that will loosen it and reduce the ph level.
