Q.lemon tree no fruit
I have had a Lemon Tree for 15 years and in that time no fruit. I was considering having it taken out. Talked about it with my gardener, stopped watering the tree now, after a couple of months it is flowering, why is that?
Water is vital to citrus tree health.
Water stress can be seen in fruit reduction, leaves turn a dull green and will curl inwards. Continued water stress and the leaves will began to dry and die.
Leaves will fall first, followed by any fruit.
Here is the surprise. Citrus will bloom about 1 month after being drought stressed.
It's important to continue to water your tree if you want it to continue to grow.
