It also seems that the apple tree needs a cold snap. not sure why.
Chill Requirement
Some fruit trees have a chilling requirement – a minimum number of hours, or “chill hours,” in temperatures of 45 degrees Fahrenheit or colder, to produce blooms. Anna, bred in Israel, is considered the ideal apple tree for mild climates because it requires only 200 to 300 chill hours. Apple tree roots, however, require the soil temperature to remain above 15 degrees Fahrenheit. _sfgate
So I guess it's a good thing for us here in Mililani that it's been quite cold, and that seems to have triggered something in the plant.
So in reading a little more, the question is if the Apple tree is 'self pollinating' or not. So we're breaking out the paintbrush and 'painting' the flowers ourselves. This has worked before, from bell peppers to cucumbers.
Found that the Apple Tree is listed as:
- Fertility: Self-sterile
- Meaning: Plants that cannot fertilize themselves are called self-sterile, a condition which mandates cross pollination for the production of offspring.
So far, only one area on the tree has the delicate flowers. We'll be looking for more flowers since it should flower in the Spring and the Fall
