You don't need to worry about it if you use the GA3 powder. It works great and will also make all of your fruit seedless.

here is a good thread about it.

Hello Jsvand,
I will have to look at the cost of the powder if it is cheap, I will buy the tree. If not I will go without.

It's pretty cheap. $12 and it is enough to pollinate hundreds of trees. Should also work on your keylime as well.

Jsvand,
I may just end up buyin it for the keylime. I have had two bloom flushes and no fruitset at all. It is strange to me the way these blossoms grow. Most citrus that I have grown open there blooms and then the individual petals fall off. The keylime(for me at least) drops the entire bloom at once. I tried pollinating a few random blooms tonight but I am not that hopefull. The tree is quite large now. It has grown over a foot since I bought it this summer and has has not stopped growing yet. I prune it every couple months and presto! More growth! I also think it may just be from being indoors and I know it is still small but I hope by this summer it will hold fruit. Thanks for your help.

Jsvand, Dose the GA3 works on kumquat? My tree had lots of flowers last year but only a few fruits were set. my yard seem to have no bees at all.

Not sure on the kumquats but I don't see why it wouldn't. Try asking on the citrus forum from my link. Lots of people there that know way more than me about citrus.
