I live in So. Calf and planted a meyer lemon last Sept.05. It has about 8 lemons, most of them look like they are mature, except they never turned yellow. It looks like there is some fungus and curling leaves. I am need to all this and have no idea why they are not turning yellow.
How long have the lemons looked to mature? Lemons can take many months to ripen. I think its like 8-10 months from flowering. Do you have a picture of the fungas and leaves? need more description
Meyer lemons are a cross with an orange as one of its parents. Myer lemons, when they are mature (ripe) do not turn yellow they turn orange. When they are mature they will turn color. - Millet
