Twitter follower @Oolonggirl asked, "How often do you fertilize the tea plants?" Roy replies:
For spring harvest we do it once during the fall, after trimming. If we plan on picking a fall harvest, we fertilize after spring. For my tea farm in California I am not yet sure what we will do. The decision is farm specific; you decide what to do based on the land, varietal, and how much the tea is harvested. In general, fertilization is required to replenish the plant's energy so it can grow new leaves.
