Prune at the Right Time

This shop has the most fantastic, healthy, gorgeous plants. I am a repeat customer and have never been disappointed. In fact the plants have always exceeded my expectation and plants are often much larger than expected. Packaging is some of the most professional I've seen, with not one leaf damaged. I'll be back for more.
