The loquat is normally pollinated by bees. Flowers of the early and late flushes tend to have abnormal stamens and very little viable pollen. Thinning of flowers and young fruits in the cluster, or clipping off all or part of flower and fruit clusters is sometimes done to enhance fruit size. Under most conditions the loquat tends to develop an alternate-bearing pattern, which can be modified somewhat by cluster thinning in heavy production years. For the highest quality fruit the clusters are sometimes bagged to protect from sunburn and eliminate bird damage.
Loquats are wind tolerant and grow best in full sun, but also do well in partial shade.
The round headed trees can be used to shade a patio. Loquats also make attractive espaliers. Loquats grow well on a variety of soils of moderate fertility, from light sandy loam to heavy clay and even limestone soils, but need good drainage. Loquat trees are drought tolerant, but they will produce higher quality fruit with regular, deep watering. The trees should be watered at the swelling of blossoms and 2 to 3 waterings should be given during harvest time.
