Reasons For Guava Trees Not Fruiting
In this article we are assuming that you were successful in planting a guava tree but it is not fruiting or you have a grown up tree that you trying to find suitable growing conditions for it so it can bear fruits.
Lack of Pollination: Guava trees are big fans of pollination when it come to bearing fruits. If your tree is blossoming then you are on the right way. The next step is to fertilize those blossoms. Although guavas are self-fruitful, however, leaving the tree on its own will yield only 15%, don't be surprised. This improves to 40% if you hand self-pollinate or even higher if cross pollination is possible. The major pollinator of guavas is the honey bee. So for indoor trees make sure you use your hands to help.
Soil Conditions: Well-drained soil is necessary for this plant to thrive. The roots like moist conditions but not drowning. In hot climates you can use mulch to preserve the moisture. Water every other day when the tree recently planted to 2 months old then at least once weekly provided that the soil is always moist. If planting in a pot, choose a 15 gallon planting pots with drainage to ensure root growth and abundance of nutrients. Manure is recommended as a natural soil amendment. If not available then a medium N-P-K ratio fertilizer will do the trick. This can be applied every 2 months in the first 2 years then every 3-4 months later on.
