Polka is a very easy to grow Weigela that adapts to most soil types provided they are well-drained. Give this plant plenty of sun.

To plant, dig a hole no deeper than the root ball and two to three times the width of the root ball and fill it with water. If the hole drains within a few hours, you have good drainage. If the water is still standing 12 hours later, improve the drainage in your bed, perhaps by establishing a raised bed or mound. Turn and break up the soil removed from the planting hole. If the native soil is heavy clay, mix some organic compost at a 50/50 ratio with the soil removed from planting hole. Remove your plant from its container and, if root bound, loosen the exterior roots a bit. Set the plant into the hole you've prepared, making sure the top of the root ball is slightly above the soil level. Pull your backfill soil mixture around the root ball in the hole, tamping as you go to remove air pockets. Then water thoroughly and cover with a one to two-inch layer of mulch.

I fertilize Weigela one time a year with a well-balanced shrub & tree type fertilizer after they've bloomed in spring.

I've seen no serious insect or disease problems with Polka Weigela. These are quite tough, long-lived shrubs. Consistently wet or soggy soil could cause problems with the roots.
