lemonade tree not producing flowers
Hi, I planted our lemonade tree approx 4 years ago and it produced an abundance of flowers the first year, I trimmed the tree prior to it producing fruit (as it was growing very fast) and inadvertently trimmed most of the flowering branches. The tree has grown quite considerably since then and is now approx 10 to 12 feet high but has all but failed to flower there is one top branch with 4 or 5 flowers on it but that is all. How do I encourage the tree to flower?

If you are feeding it, then check and make sure that it contains enough phosphorus and potassium. Feed with too much nitrogen will half flowering.
If you do not feed it, then it is likely that it doesn't have enough phosphorus and potassium in the soil.

Alternatively, if it were pruned too heavily when it was young, you could have lost the top graft, leaving you with only the rootstock. Most commonly the rootstock is 'Flying Dragon' which is hardy but will not fruit. On the rare occasion that it does fruit, they are not edible, at all.
Make sure to check and make sure that all growth comes from ABOVE the graft knot close the the base of the tree. If any of these shoots come straight out of the ground, then they are likely the rootstock and not the tree that you purchased.
