Anyone plan to spray GA3 on their jujube flowers this year? I was busy doing other things, the next thing I know, my jujubes are flowering. I will not be able to spray it until this Sat.
I don’t know if we should spray when trees are just start to flower or fully flower. Anyone know or has done it?
I have never really considered it. I have some trees that are very stingy with fruit and some that are loaded. My fruit set is better than last year. All the time my trees were blooming it was raining every day. I do t think any spray would have been effective anyway.
I kinda feel that my non fruiting trees need a correction of some sort but I’m thinking in soil pH. I have acid soil and I think they do better in a bit of alkalinity.
I wish I had your problem. My So from Burntridge set a few fruit on year 2 (the fruit were unimpressive). Since then, it has not set any fruit since then. It is 5 years old now.
My Shanxi Li has had tons of flowers every year but set a few fruit. Some of the fruit sized up a bit, turned brown and dropped. Probably it is a pollination issue but SC and HJ are 8 and 12 ft away.
I grafted 12+ grafts on it these past 3 years. Something will be the right partner for my Shanxi Li, I hope.
@mamuang here’s a pic of Honey Jar and Sihong seedlings from this year. They are in potting mix with Osmocote and we have had an over abundance of rain. Proof the jujubes like fertilizer and water.
@jujubemulberry photo of a seedling of Vegas Candy. Candy has been vigorous here and so is her offspring. Fruited last year also with small sweet fruit.
Those are in gallon pots. The stick is an 18” stick stuck into one of the pots so they are about 12” tall more or less. I make my own mix. A local company puts out a Landscape and Growers mix that is mostly small pine/cedar bark fines and they mix in a bit of peat and sand. I add perlite and Osmocote.
I sprayed GA3 in the evening 4 days ago. That was the beginning of a heat wave. I’ve noticed many flowers turned brown the following evening after a 90+ degree day.
I wonder whether or not those flowers were damaged by my spraying acid (GA3) on them.
@BobVance did you have a chance to spray GA3? If so, have you noticed the same browning of flowers?
I still can’t find my GA3 from last year and the replacement GA3 which was supposed to arrive on 6/23 is still in transit with USPS (ugh!). I checked out one tree (on my way to the mailbox to check for GA3…) and saw a few brown flowers, but not that many. I suspect that it has been hot enough recently (95F yesterday) to dry out any where pollination/set failed. If most of the flowers dry up that would be a problem, but I wouldn’t worry about a few.
