1. When the temperature is over 90 degrees, foliage will wilt, but don’t confuse this with wilting caused by underwatering.
2. The old-school gardening advice with roses is to prune stems at a 45-degree angle away from the bud eye. But there’s no evidence that this is necessary.
3. Many of today’s garden roses can be planted in containers, but they perform best in pots 18 inches in diameter with a clearance of 18 inches in height.
4. It’s best to stop grooming roses six to eight weeks before your first fall frost date.

7. Four characteristics of garden roses:
- Naturally disease-resistant
