Hi! I wanted to plant a sky pencil holly in a large square container. Is it ok to put small to medium size river rocks on the bottom before adding the soil? I don’t want the planter to have a hole on the bottom because it’ll stain the concrete on my porch when watered. Please advice. Thank you in advance! Hope
This won’t work out well. As carefully as you might water, rain will likely saturate the soil and the plant will drown. Even if it somehow survives the summer it will die over winter. Repeated freezing and thawing won’t allow the plant to enter dormancy like it would if planted in the ground. That repeated freezing and thawing will kill the plant and will also likely crack or shatter the container.
