citrus trees unhealthy for months
im trying to figure out what is wrong with my two citrus trees. One is a couple years older than the other and theyre planted 3-4 ft from each other. They have been looking like this for months - they both receive water from buried drop lines. Ive tried increasing and decreasing the amount and consistency of the water they get, to no avail. The leaves look sick - not really falling off, but yellowing and eventually turning brown or getting holes in them. Ive fertilized them with citrus fertilizer at the start of the spring (around 2 months ago) and nothing changed except it encouraged blossom production i think. Someone help me out!
