Polygala x dalmaisiana Care
Best is a sunny warm position Polygala x dalmaisiana is a remarkably hardy plant.
In containers use a good quality potting mix, in the garden grow in a humus rich moist but well drained soil. Water in with a liquid seaweed fertilizer. An application of general purpose slow release fertilizer in early spring and again in early summer seems adequate.
Water regularly through the first summer and lightly mulch around the plants to maintain some moisture and help suppress weeds.
Plants can be easily pruned back after the first flush of flowers to help maintain a bush habit.
