It sounds like you are doing the right things. Can I assume your tree is in the ground. It can take 3 to 5 years before in ground trees start producing with any volume. do you have any pictures.

Thanks for the reply. I'm starting to learn it will take a couple years. I was thrown off by the fact that it immediately produced 4 lemons. But those were from the production the tree the graft came off of,i suppose. My ignorance. Yes it's in the ground. I'll post some photos.

Fruit trees in pots tend to produce fruit when their roots hit the bottom of the pot and fill it up. When it is put into a larger pot or in the ground, it often takes the energy used to make fruit to then make a larger root mass and more foliage and branches instead.

This usually means no or little fruit for a season or two/three depending on how much root room it has to fill. Think of it as a savings deposit for future rewards. ;)

Also just an fyi; Meyer lemons need more fertilizing than most other citrus. Monthly during warm weather is probably the best when it's in the ground. If it's a seasonal type fertilizer, then cut the amount accordingly and feed monthly. If you tell us the brand and the NPK ratio (those numbers with the hyphens between on the package, like 1-1-1 for example) we can see if that's a good food for you.

Glad to see this thread because I just moved to Napa serval weeks ago and bought a couple of small Meyer lemons and a lime tree and some other citrus plants to grow in pots on my patio. My Meyer lemons are blooming like crazy right now in mid April with about 20 to 30 bucks per plant. I'm glad to know I do not have to thin those.
