Use a light fertilizer in 2 weeks for healthy growth of the plant. When the plant is about 6 inches tall, you should pinch about ¾ inch of each branch, as it helps in promoting blooms and bushier plants. After they reach a height of a foot, do the pinching process again. Remove all the buds except the top ones.
Caring for the Plant
You should remove the dried and wilted leaves of the plant. This helps in providing the nutrients and energy to the healthy plants. The plant should be pruned, when it is about 6 inches tall. You will find that your plant is covered with mulch or straw after each blooming season.
