Why is my lemon tree not growing any branches?
I have two lemon trees on my balcony, about 1,5 year old that grew out of seeds (found sprouting seeds inside of a very large lemon from someones lemon tree). It was fun to watch them grow but I realized that they are not growing any lateral branches. One tree is about 4 feet tall and the other one is very small for some reason. What should I do to have them start growing side branches and hopefully bloom someday??I am new to gardening and only planted these lemon seeds because they were sprouting and I thought it would be fun to have lemon trees and see if they would actually grow out of those seeds. Now I am much more involved and would like to take a better care of them.
Thank you for all responses and advices:)
Here is a picture of my young lemon trees. Maybe it will help:
