Maintenance Notes:

"Feet in the shade, head in the sun" - that's the old saying to remember for success with clematis. Plant this vine where the leaves get plenty of sunshine while the roots enjoy cool shade. Mulch is one way to do this; you can also plant a clematis where the roots are shaded by a low-growing, evergreen shrub.

'Viva Polonia' clematis blooms on both old wood and new wood. To get the best performance and best appearance, cut it back to about 3' (.9 m) each early spring.

Grower Tips:

Grow plants cool early in the season to prevent top growth from outpacing root development, which complicates maintenance later. Lower fertility also helps with this issue.

Should be grown in larger, rather than smaller, pots, with a bamboo trellis or similar structure placed in the soil. Use a light, fast-draining growing media.  Pinch/prune 2-3 times to encourage branching and minimize plants growing into each other.

Plants benefit from manual training of vines onto support structure, which results is less maintenance and a more appealing plant at retail.

Once flower buds have set, grow plants drier to prevent clematis wilt. Spray with thiophanate-methyl fungicide as a preventative.

Top-dress with rice hulls or something similar to minimize weeds, algae, liverwort, etc., since leaf coverage of soil is minimal.

Should be last plants to be moved outdoors.

Potting a 2 ¼” liner directly to a 3 gallon can is not recommended.

Additional notes on Happy Jack® Purple and 'Diamond Ball': One of the easiest varieties to ship in bud and bloom.

Additional notes on 'Sweet Summer Love': Late bloom makes shipping flowering plants tricky. Being pot-bound seems to encourage blooming on this variety.
