1. Bud formation can be observed on new growth on the plant (early winter)
2. Flower buds clearly formed and leaves start to develop (early spring, ? 3 months)
3. Flowers fully develop and are pollinated by wind or insects (early spring, ? 3½ months)
4. If successfully pollinated, flowers die back and incipient fruit can be observed; leaves have quickly grown to provide tree with food and energy from photosynthesis (mid-spring, ? 4 months)
5. Fruit is well developed and continues to grow (late spring, ? 5½ months)
6. Fruit fully ripens to an edible form to encourage spreading of seed contained within by animals (midsummer, ? 7½ months)
