“I have a lemon tree that’s five, or six, years old. I was wondering how old they have to be to produce fruit, and if there has to be two of them, or is cross-pollination not necessary?” Question from Royce of Texas
Answer: A lemon tree should be fruitful by five years of age. Most lemons are self-fruitful and do not require cross-pollination, but they do require bright sunlight and good care to flowering and fruiting. Has your tree begun to flower? If so, give it good care and it should begin fruiting for you. For care instructions, I recommend you read our article titled Growing Lemons, Oranges and Other Citrus Indoors (click here to view the article). It will give you all the information you need to encourage your indoor lemon to fruit.
Happy gardening!
