Lemon Tree

Question

I bought a lemon tree from Bunnings 2 years ago. It has grown to 2m high, and it looks very healthy. It’s a great looking tree, but it has not flowered. I have used a seaweed granular fertilizer and a spray on citrus fertilizer. The lime trees planted in the same area have flowered and fruited well. What can I do to make this tree flower and fruit?

Answer 1

It may have too much nitrogen. Give it some high phosphorus fertilizer to counter any nitrogen overload the plant may have. All well rounded fertilizers will contain nitrogen, phosphorus and potassium. However, plants can sometimes have a bit of trouble balancing out their fertilizer. If you leave it alone, the plant will naturally use up the nitrogen (which is for healthy leaf growth) and should balance itself back out. But, if you want to speed things along, a little bone meal, which is a high phosphorus fertilizer, will move things along quicker.
