What is the growth process of blackberry?

Blackberries have extremely high requirements for planting land and environment. Soil moisture and fertility should be moderate, and its growth has the habit of creeping up. The arched stem has short, curved but sharp thorns. When the bent and drooping branches touch the ground, they will grow roots from the nodes at the top of the branches. Because of this characteristic and the rapid growth of blackberries, blackberries growing in woodlands, shrubs and hillsides can spread outward and occupy a large area of land in a short time. The prophase of blackberry can produce more drupes than anaphase. There are several possibilities for such symptoms: root failure, the number of reluctant pollinators, or slight changes in environmental conditions, such as rainy days or too hot weather, which make bees unable to work after early morning, leading to fewer visits by bees or fewer pollen grains passed to flowers, and ultimately reducing the quality of fruits. Drupe only develops near the ovule; Male gametes in pollen grains fertilize the ovule. The ripening time of fruit is mainly from the end of June to the beginning of August for more than one month, and it must be picked manually, which is a labor-intensive industry.
