My father has planted 3 apple trees in our piece of land in Nyeri,Kenya.The place is in the central highlands of kenya in Africa. The problem is that of the three 3-year old trees ,only one produces any flowers and they are not even many.Then the fruits that result are very small. What measures can I take to help him enjoy these rare fruits(apples are temperate in origin and therefore rare and expensive for most people here). I have no clue what variety they are. Although I have not seen it with my own eyes I do know that some people actually grow apples and pears here in Nyeri-and successfully.
