We usually ship perennials to you in their dormant state, that is: bare roots, usually without leaves, in bags of loose peat moss. They may have some shoots beginning to grow. It is very important to plant these dormant perennials as soon as possible after you receive them. If it is absolutely necessary to store them for a short time before planting them, open the cartons and any plastic that is around the roots. If the roots appear dry, soak them for a few hours in warm water. Thereafter store in slightly moist peat moss in a cold, but not freezing location until you can plant. They can also be placed in pots of soil if planting will be delayed for more than 2 weeks. Use any packaged, peat-based potting soil and pots with drainage holes.
Trim off any stems that have sprouted on your bare-root clematis back to 12 inches if any longer than that have sprouted from the crown. This helps prevent breakage, gives new roots less plant to support while establishing and promotes branching once the plant starts to put on new growth. Soak your bare-root in a bucket of water for at least one hour. Fill a 1-gallon pot half full with moist potting soil.
Create a cone of potting soil in the bottom of the pot. Bare-root clematis establish better with their roots slightly constricted in a pot, than lost in a the wide-open soil, according to the International Clematis Society.Spread the roots around the the soil, adjusting the plant so the crown -- where the plant emerges from the roots -- will be 2 inches below the soil line, or about 3 inches from the pot's rim. Insert a bamboo stake just behind the plant and its roots in the pot to support any new growth. Water the plant in well. Place the pot in a protected area that receives morning sun. Provide 1 inch of water per week.
Once established plants generally have some drought tolerance and will only need to be watered if the season is hot and dry.
Prune early flowering clematis varieties with hand pruners immediately after flowering. Do not cut into woody growth. Late-flowering types are pruned immediately after flowering back to 2 to 3 feet tall, once mature. Cut back large-flowered types, which bloom on new and old wood, on late spring, by removing old wood and in summer by cutting the plant back to 18 inches tall after blooming.
