Since lychee flowers are functionally unisexual, fruit set can occur only if pollen from male flowers (M1 and M2) is transferred to the stigma of F flowers. Lychee flowers are entemophilic and pollination is usually performed by insects, one of which is the honeybee (Free, 1993; King et al., 1989; McGregor, 1976).
Do lychee trees need cross pollination?

Are lychee seeds poisonous?
Lychee seeds are poisonous, and unripe lychee can also be toxic. Avoid eating the pit or the fruit if it’s not ripened.

Do lychee trees need pruning?

Select branches are pruned from the center of young trees to open up the canopy to good air flow and reduce wind damage. When pruning a lychee tree, always use clean, sharp tools to avoid the spread of disease.
Can lychee self pollinate?
Self-pollination may occur in lychee, however, flowers are generally recognised as self-sterile and require insects to transport pollen from anther to stigma for fruit to set (Badiyala and Garg 1990; DuToit 1994; McGregor 1976).

Lychees have a reputation as drought tolerant, but you need to irrigate newly planted lychee trees regularly during the first few seasons. After the trees mature, however, irrigation can reduce flowering. Stop water the trees during the fall and winter until they bloom. This usually produces more flowers.
Why we should not eat lychee?
