First, in using Treadwell Perennials, remember a few rules:
1. Pick the right plant for the right spot. Sun vs. shade, part-sun vs. full sun, etc.
2. Gauge how much foot traffic: light (occasional); moderate (once or twice a day); and heavy.
3. Consider the amount of drainage the area you have in mind has. Keep the site as level as possible.
4. Water well after first planting and maintain a regular watering schedule until they are established, just like all newly planted plants.
5. Determine how many to plant: tight spaces between paving stones would allow you to split up a bushy plant, while larger areas would benefit from planting the whole plant.
So, if you need a plant that is durable, dependable, and tough, consider using a Treadwell to meet your landscaping requirements.
