Q.8 yr old lemon tree gives 3-4 lemons about every 3-4 months. It is fertilised and enough water, but very few lemons..thank you
The lemon tree gets adequate fertilizer I think and enough water. I give 7 litres twice a week. Sorry I don’t have a photo; the tree is lovely and green and it gets the flowers, but very few fruit. thank you. Diane Bremner

Being in Washington, I am assuming that these are in container, and are brought in during the winter. The most common factor with low fruiting is light, Windows filter quite a bit out, and will not allow for proper fruiting alone. A horticultural grade light of 200 watts or greater will be required for any significant fruit set.
Other factors can include fertilization, which should be done with a citrus specific fertilizer once or twice per year.
