Click on links below to jump to that question.
It may be a pollination issue. Particularly with loquats. They can self pollinate, but do not do it well. If you add to that a lack of pollinators, the tree will not produce. I would recommend trying to hand pollinate some of the flowers with a small paintbrush the next time it flowers. If all the flowers produce, it is a general pollination issue and you will either need to hand pollinate the tree or make adjustments to attract pollinators. If only some of the flowers fruit, it is a cross pollination issue and you may want to consider planting a second tree.
This year leaves became yellow and falling down in big numbers. This is not a young tree, but I do not know the age. Some portion of roots extend from the soil level. Please give me advice.
There are many reasons a tree can get yellow leaves. This article will cover some of those reasons: https://www.gardeningknowhow.com/plant-problems/environmental/plant-leaves-turn-yellow.htm That being said, tree diseases are very hard to diagnose without seeing the tree, so I would recommend hiring a local tree specialist to come look at the tree and advise you on it.
It may be a fertilizing issue, likely a nitrogen/phosphorus inbalance. Too much nitrogen in the soil will prodcue healthy growth but limite flowering and fruiting production. Try adding some more phosphorus-rich fertilizer or bone meal to the soil to sncourage more flowering and fruiting.
We have a loquat that was that has been grown by my son from a seed to now 4 ft tall and potted. Recently something has started eating the leaves and new shoots. I removed a large grasshopper several weeks ago, but the damage is getting worse. What over the counter product can I use to treat safely?
