Self-sterile or self-infertile means that another tree of a different cultivar or variety is needed to set fruit (cross-pollinate). This is the case with most apples. Monoecious (from Greek meaning 'one household') plants have their female and male parts on separate flowers both together on the same plant.
Just so, what is a self sterile apple tree?
Self sterile – cannot pollinate themselves. Most apples are self sterile, as are all pears, many plums and quite a few cherries. These trees need to be pollinated by another tree of the same Genus / type, ie apples pollinate apples, Pears pollinate pears, but by another variety NOT the same.
Additionally, do you need 2 apple trees to pollinate? Most apple varieties do not pollinate themselves or any flowers of the same apple variety; this requires planting at least two different apple tree varieties close to one another so that the bees can pollinate. (There are actually some self-pollinating apple tree varieties if you are really short on space.
Keeping this in view, can you self pollinate apple trees?
Pollinating Apple Tree Flowers Like all fruit trees, apples need to be pollinated if they are to set fruit. While some varieties of apple are able to fertilize themselves (trees described as 'self-fertile'), others require pollen from another tree to do the job – a process known as cross-pollination.
What apple trees are compatible for pollination?
All varieties of apple trees require some cross-pollination for fruit set.

Can you pollinate apple trees by hand?
Most apples (Malus domestica) depend on pollinating insects, especially honeybees, to transfer pollen from flower to flower to set fruit. Hand pollination is a time-consuming but effective means of ensuring fruit growth for limited numbers of trees, although some commercial growers in Asia use it.How close do apple trees need to be to pollinate each other?
50 feetWill a plum tree pollinate an apple tree?
Other fruit trees, like most apple, plum, sweet cherry and pears are cross-pollinating or self-unfruitful. They need another tree for pollination, and not just one of the same variety, but a different variety of the same fruit. Fruit trees form their flower buds in the fall.What does it mean when a tree needs a pollinator?
Pollination of fruit trees is required to produce seeds with surrounding fruit. It is the process of moving pollen from the anther to the stigma, either in the same flower or in another flower. In fruit trees, bees are an essential part of the pollination process for the formation of fruit.What does self sterile mean in fruit trees?
Self-sterile or self-infertile means that another tree of a different cultivar or variety is needed to set fruit (cross-pollinate). This is the case with most apples.How do you self pollinate fruit trees?
Pollinate by hand.- Fluff up a cotton swab by pinching the end and pulling. (A small paintbrush can work as well.)
- Dip the swab onto the pollen of a flower.
- Carry the pollen to a second flower and brush it onto a stigma, or sticky female area.
- Remember to transfer pollen between two different, compatible cultivars.
