Emerald Harvest Sturdy Stalk's key ingredient—silica—fortifies your plants and enriches the internal structures needed to support top-heavy plants laden with flowers and fruits. Because silica strengthens cells, silica helps plants withstand environmental and other stressors, so that they spend more of their energy creating blooms and buds. This results in a productive, vigorous garden with heightened resistance to pests, insects and pathogenic airborne and waterborne diseases.

The other main ingredient in Emerald Harvest Sturdy Stalk, potassium, helps your plants get the most benefit from photosynthesis, no matter with what light or where your plants are cultivated. Equally important in outdoor and soilless gardens, potassium is essential for strong vegetative growth and yields.

Use Emerald Harvest Sturdy Stalk as a supplement to a base nutrient series for guaranteed professional results.

Tips & tricks:

  • Use as needed, rather than as part of a regular feeding schedule. For example:
    • It can bolster crops during stressful times in the crop life cycle, such as transition or transplanting.
    • It can support bulking buds during mid or late flowering.
  • Use on top of (not in place of) a quality bloom booster. Although Sturdy Stalk does increase flowering, it does not contain sufficient potassium to serve as a stand-alone bloom booster.
  • Use alone on a watering day or mix it last after other nutrients and then feed the nutrient solution to your crops immediately. The potassium silicate in the formulation is highly reactive with other nutrient ingredients.
