Despawn from Cactus#929

I have a cactus farm, with this there is the problem of the infinite stacking of cacti, the despawn timer is reset again and again, which means the cacti are somewhere in the farm on a fence and collect all the cacti that would not normally land there and so on comes down less and less. So my question is there any possibility to cancel the stacking with the cactus or that the timer is not reset?

It sounds like your farm design is just bad…

Use a collector.
