Pinching and Growth Regulators
B-9 is effective at controlling height and darkening foliage color. Prune or pinching soon after potting will produce a finished product that doesn't open up when it flowers. The key is to make the first prune at the level of the first set of leaves closest to the soil.

Pest and Disease Management
Aphids, Leaf Spot, Watch for Mildews

Grower Tips
Can be produced as a flowering greenhouse pot crop for Mother's Day H. macrophylla: Lower pH (5.0 to 5.5) will induce bluer flowers. Higher pH (6.0 to 7.0) will induce pinker flowers.
