|This is normal fruit drop in apricot. The fruit was mature|
and ready to be picked and a good wind came along
and blew them off of the tree during the night.
Q. Our Pepper tree is losing it’s leaves and they are dropping like crazy. Can you tell me what I can do or is this normal this time of year? Also the fruit is dropping off apricot tree.
A. Leaf and fruit drop can be from very similar causes, usually some form of stress. This stress can come from temperature extremes, irrigation and soil moisture extremes or wildly fluctuating soil moistures. Unlike leaves, for fruit to stay on the plant or tree the flower needs to be pollinated and the environment should be fruit-friendly.
Even though flowers are modified forms of leaves for fruit to develop then it must include the transfer of pollen from male parts of a flower to female parts of the flower. During this transfer it is best done by insects like bees in those trees and plants requiring pollination by insects (most fruit trees and vegetables).
During pollination (which can cover a period of a couple of weeks in cool weather because the flowers don’t all open at once) it is best if the weather is friendly to pollinators (good temperatures, good humidity and normal winds) as well as pollination. So when the flowers are open you hope for warm weather free from rain and storms. When these conditions vary further and further from ideal then the amount of fruit set may be diminished.
|Early almond drop in May due to lack of pollination. The |
yellow almonds have not been pollinated so no nut has
formed and the whole nut drops from the tree two months
Without pollination many fruits cannot develop more than just its juvenile stage and then drop. The fruit tree thins itself in this manner but not enough for our pleasure. This can be normal but should not be all of the fruit. This is called “June drop” which happens in our climate earlier, sometime in late April or early May usually.
|Plum fruits, if they do not get pollinated, will grow for awhile|
but eventually yellow and drop from the tree early while
pollinated fruit (green here) will continue on to maturity.
With your California pepper it is most likely irregular or having a streak of hot weather that the plants were not prepared for. Make sure if you get hit with hot weather out of the norm to run them through an irrigation cycle ahead of schedule.
