1.  Site: Most  perennials prefer six to eight hours of sun per a day. And some tall perennials need wind protection.

2. Planning: Think about the combinations of color, texture, height, etc. They look best when planted in "drifts" of several plants rather than as single plants or in rows.

3. Soil: Good water drainage characteristics is a necessity and needs incorporating of organic matter such as compost or peat moss aids.

4. Planting: Spring is generally is preferred, but it will depend on the grower.

5.Water: One inch  to one and three quarters inch of water per week is a general rule.

6.Fertilization: Application of a "starter" fertilizer may aid in more rapid establishment of a good root system and a handful of bone meal or super phosphate(0-19-0) worked into the soil about the plant in the spring can be beneficial.

7.Maintenance: Taller species may require staking and a mulch applied to the soil will help suppress weeds. Do not place mulch too close to the crown as this may hold excess moisture and result  in disease problems.

8.Winter protection: Perennials can be damaged by cold temperatures and frost. Mulch about three inches thick is helpful. Apply winter mulches after the ground freezes, usually in late November.

9.Dividing and Transplanting: Most perennials can be divided. Some of them need to be done annually or every three to four years. Remove the root damage and remove diseased parts. Replant the new divisions as soon as possible.Take care to replant the division at the proper depth. Water well and protect the plant from the sun on bright, warm days.
