The plant needs to be “pinched” back periodically to control its height and to promote a fuller plant. Keeping the humidity high and reducing light and heat stress after plants are pinched can help ensure all of the axillary branches develop normally. As poinsettias grow, and go through different developmental stages, their rate of nutrient uptake changes. Shortly after flower initiation, the plants go through a brief period of lower fertilizer usage. Keeping the humidity high and reducing light and heat stress can help all of the branches develop normally. However, I personally am no fan of phosphoric acid.
