| Maintenance Notes |
These drought tolerant plants should be planted in well drained soils and would do well in sandier areas. Avoid overwatering and let the soil dry down a little in between waterings. If your plant begins to look a bit tired or leggy, use a sharp pair of scissors or pruning shears to trim back the plant to maintain it's shape and promote new growth. |
