Anything else that cause fruit drop on Meyer Lemon? - Knowledgebase Question

Hello again -

My lemon gets more than 6 hours sun, the soil is consistently moist, it has been fertilized all-purpose fish emulsion and is producing lovely green growth. I know that a young tree will take a few years to set fruit while it develops its canopy but my tree is about 5-6 years old now and last year produced a couple dozen lemons. The only thing it is suffering from right now is a bout with citrus leafminer.
Do I need to change my fertilizer? Higher phospherous?

Thanks for all your help!

It sounds as though your tree is receiving all the necessary elements to keep it healthy and happy. Your fertilizer is just fine - I wouldn't change a thing. Leafminers shouldn't affect the fruiting ability. If your tree produced fruit last year but dropped all the fruit this year, I wonder if it has gone into a cycle of alternate bearing. Alternate bearing (fruiting every other year) can become a problem for some types of citrus. Trees that alternately bear normally crop lightly (10 to 25 percent of normal crop) following years when crops are heavy. Wish I knew for sure! Your tree should flower again this year. Let's hope it holds its fruit!
