Hi! I have air layered kumquats, a couple of ponderosas and a yuzu lemon all attempting to flower - each one is less than 5 months old from the time I cut them off the mother tree and put them in their own 3 gal pot. Should I pinch the flower buds off now or wait til they form microscopic fruits and then pinch those? Mother plants are all 6 years and upwards (owned by a friend) and I was told by the owner that his plants are setting fruit about now.
