I have a lemon tree that blooms flowers. The flowers turn into very small green lemons but after a while they turn yellow and fall off the tree. Is there something I can do so that the lemon will continue to grow?

There can be a few things happening that can cause the fruit to drop. The most common is that the flowers were not pollinated. If your tree is located in a place where pollinators can't get to it, you can hand pollinate it with a small paint brush. Just go from flower to flower and swirl the paintbrush inside the flower.
The second most common reason for baby lemon drop is a lack of water. Lemon trees need more water when they are in fruit and it is helpful to provide more water to them when they are in fruit.
The most likely problem is that the tree has too many fruit to support. You can pinch off some of the flowers, and you can also pinch off some (app. 3 out of every 4) fruits when they are still green, to see what happens.
