I had a few cylindrical glass vases left over from our wedding (which held my bridesmaid's bouquets) and decided another project was in order.
I saw something similar being sold on Abbot Kinney (in Venice, CA) a few months back for an astronomical amount. I was able to recreate them for $5.50 each.
We'll see how they do! I left the root ball in tact and poured sand all around. I covered the plants with foil during the sand pouring process (after reading this tutorial) in order to try to keep the sand off the plant. Then, I used a long soft-bristled paint brush to wipe any stray bits (as best as I could) of sand off the plants.
I'm quite pleased with the outcome. We'll see how the first watering goes!
