Growth Tips | Inkberry holly is not drought tolerant, and does best in soils with consistent moisture. Can tolerate occasional periods of wet soil. If you wish to prune, do so after it blooms in late spring. Inkberry hollies make an excellent native alternative to boxwood. However, they are not quite as shade tolerant nor as deer resistant as boxwood is, so should be treated accordingly. Nothing special is required in terms of fertilizer - one application of a granular (not liquid) fertilizer formulated for trees and shrubs in early spring is sufficient. May be fertilized monthly from early spring through late July if desired.Squeeze Box inkberry holly is a male variety. It will not develop fruit, but if planted within 50'/15m of a female inkberry holly like Gem Box or Strongbox, they will develop berries. Squeeze Box can also be enjoyed on its own as a specimen, hedge plant, or garden plant. Its upright habit makes a great structure for holiday lights, too. |

Understanding Plant Pot Sizes
When you’re choosing plants, you’ll often see sizes listed as #1, #2, or #3 containers. These numbers refer to the volume of the pot, not the age of the plant.
#1 Pot – Holds about 1 gallon of soil. These are small starter plants, great for tight spaces or filling in around larger features.
#2 Pot – Holds about 2 gallons of soil. A medium size that balances affordability with faster establishment in the landscape.
#3 Pot – Holds about 3 gallons of soil. These larger plants give more immediate impact and tend to establish quickly.
Bigger pots generally mean more mature root systems, but the right choice depends on your project goals, timeline, and budget.
