This is a miniature orange that came from a tree growing in a greenhouse at the Dallas Arboretum. On Friday I was part of a group that went on a private tour of the growing and staging areas there. The greenhouse with the orange trees had the most amazing flowery sweet scent to it.
Jimmy Turner led the tour. He’s the horticulturalist in charge of the place, and I thought I would pass along three of his tips:
- The best containers for all over flowering are the kind sold at HangingBaskets.com. They far outperform coir in Texas heat. They are completely reusable.
- The best source for wire topiaries is Green Piece out of Canada. They are surprisingly inexpensive.
- Expanded shale is hands down the number one soil amendment for improving the clay soil in North Texas.
