For larger Citrus Fruit
« on: July 09, 2024, 05:10:27 PM »
This week is the time to foliar spray your citrus trees with low biuret urea.  Doing so will produce larger sized fruit.

Because it is a fertilizer, it will work to some ability but I don't know of any research on that.

Does it also help keep the fruit on the tree? My potted Morton drops the fruit every year so far the last 3 years. I pollinated flowers with Ichang, Calamondin, and Meyer and only the x Meyer fruit is left

Vnomonee, Yes low biuret Urea does a good job helping a tree to retain fruit.  However, research has found to accomplish fruit retention low biuret urea has to be sprayed in march or April.  This is because once the opportunity to increase flower number has passed, later applications of low biuret  urea will increase the retention of abscising reproductive organs (fruit).

I can find urea here but it never says anything about low biuret (or biuret at all). Is it vital that it is low biuret (as opposed to high? or none at all?).

Urea fertilizers that  are high in biuret can cause leaf burn.  if your urea does not show a biuret content you could spray a small portion of leaves and see if there is any  leaf burning affect.  If not then the biuret content in the product will be OK.

Fantastic advice, thanks a million.
