Q.Why doesn’t my calamondin tree bloom or fruit?
This calamondin tree was planted from the orange seed of the first orange tree I had, which flowered and bore fruit normally. The seedling tree is now 10+ years old, 9 feet tall in the pot, lush green leaves, hardy, lots of 2 inch spiky thorns on it, and will not flower or fruit. I’ve withheld water, and that doesn’t work. Will it ever flower or fruit, or is it just a genetic dud because it was grown from a seed? How much longer do I wait?
I have several other citrus trees, including other calamondin, which I bought. They flower and fruit normally. I know what to do to take care of the trees, so it’s not a health or care issue with the seedling tree.
Thank you for the help!

Typically, they are true from seed. Depending on The growth of these (They are treated very differently at a nursery than one could possibly treat them from home)they may be reluctant to flower for quite a while. They will flower much faster from cutting, so taking a branch of your fruiting trees will give you fruit in about 3 years. From seed, you will have to be patient. It could be a bit before you see flowers.
