How much fruit does the Pineapple guava/feijoa yield? Is it possible to sterilize the Pineapple guava/feijoa so it does NOT yield fruit? It would be next to the walk to the front door and I don't want the mess.
It can be very difficult to predict the yield of this tree, as it depends on the conditions of the area. You can help reduce the crop by pruning the tree often, and removing blooms after fading.
