Why tea growers use cuttings instead of seeds

Why do so many modern tea farms grow new plants from cuttings?

If a grower wants to plant Yabukita, for example, they can take a cutting from a Yabukita mother plant and let it develop roots. The cutting grows into a new tea plant with the same genetic makeup as its parent. This is what we mean by a clone.

This method helps preserve the traits the producer has chosen: the shape of the plant, how it grows, the character of its new shoots, and other useful qualities.

What happens when we plant seeds?

Tea seeds form through the plant's flowers. Tea plants have a strong tendency to reject their own pollen, so pollination between different plants plays an important role.

When this happens, genes from the two parents combine and are rearranged. The seedlings are genetically diverse. They do not all grow into copies of the mother plant.

Put simply, if we sow a handful of tea seeds, we may get plants that grow to different sizes and at different speeds. Some put out new shoots earlier than others. Their strength and resistance to disease may differ too.

Why does this matter to a tea grower?

In nature, this diversity is useful. It gives plants more opportunities to adapt to different conditions. On a commercial tea farm, the same diversity can make the work more difficult to manage.

Cuttings help growers keep the characteristics of a selected cultivar, manage the field, and work towards more consistent quality.

This is one of the ideas behind a field planted with a single tea cultivar. A producer can select a mother plant with suitable qualities and grow many plants with similar characteristics. Their growth is easier to plan around, which can make the farm more practical and economical to manage.

So behind those even rows of tea plants is a decision about how to preserve the qualities a producer wants to work with.
