Oh, it must smell heavenly! I am so envious!
My potted Meyers lemon tree is now around 20 years old. I have kept it alive carrying it out side during the summer and bring it indoors in front of a sunny window in the winter time, but it does not look nearly as luscious as yours does. Every year it gets a handful of blossoms and many of the little green lemons that it does form fall off when they are still tiny. I am probably not caring for it properly but really don't know what else to do for the poor thing.
I will tell you the essential diet and tips for a lemon plant. Change the diet chart of your plant and then see that your plant will also start bearing lots of fruits.
First of all, make sure that the soil of your plant is dry and airy, and the drainage system should be perfect because if even a little water is stored in the pot, that plant will never bear fruit. Because the lemon plant hates to stay wet. So water the plant only when the soil is dry.
Apart from this, pruning is an important task as it helps your plant focus on nourishing only those parts which are necessary. Therefore, keep cutting the dry and new branches growing in the lower part of the main stem from time to time.
If it has been a long time since you repotted this plant, then it is possible that it needs repotting and root pruning as well. Because after a while in pots, the lower roots often start getting entangled with each other, due to which the plant does not get full nutrition. So, by repotting, you can give it a slightly bigger pot or prune its lowest roots.
Before flowering, dig the soil a little and mix bone meal, mustard cake, neem cake and vermicompost in it and also give it water mixed with diluted buttermilk 2-3 times a month and add a little sea salt to the water and spray it on its leaves.
Just do these things, and then you will be so happy and satisfied with your plant that you will not feel envious of anyone else. 🤗
