Oak Tree Lacks Acorns
19 Answers
There’s an old oak tree near me that usually at this time of year is awash with acorns. This year not one! I’m sure this has happened in previous years too
Is it normal for them to ‘fruit’ every year or just alternate years?
TIA

Heavy downpours wash the pollen out of the (wind pollinating) flowers, before it has a chance to float off on the Breeze and mix with other flowers.
I've noticed that the oaks that border my garden, had a bumper crop last year, but virtually zero this year, I worried that this will affect the jay population, as Acorns are a large part of their diet.

you'll know them if you tread on them, APG. Horrible mutant thingies with sharp edges (which I think are the actual "galls").

Knopper galls are parasitic, and grow out of the acorns (destroying them), so if there is no acorns, you won't see any knopper galls.
Interestingly, another type of gall, is the currant gall, which resemble red currants, and attack the flowers, oak apples and spangle galls are two other examples, commonly seen on oak.

Here's the best I can find. Looks like their prediction was correct ...

Oak trees usually start flowering from the end of April to mid-May. Oak flowers are wind pollinated, and with the wet weather we’ve had this May we might expect acorn yields to be lower this autumn due to poor pollination conditions this spring. It’s likely to be a big contrast to autumn 2020 when there seemed to be a bumper crop of acorns which were seen carpeting the floor in many areas. We’ll have to wait and see.
