Watering

Keep soil moist, flower bud drop off if soil is too dry before flowering.

Feeding

Feed every 2 weeks when in flower, with flowering plant fertilizer that has been diluted to half the recommended strength.

Germination

Sow seeds on surface of seed and cutting compost. Do not cover seed tray with newspaper. Seeds do not germinate all at once and don't discard the container until well over the time suggested. Primula Sinensis needs dark to germinate.

Propagation

Large plants can be divided every 3-5 years in late Summer. After flowering, remove plant from pot and shake soil from around roots. Gently pull root and stems apart. Plant in pot or in a shady place in the garden. Sow seeds in seed and cutting compost in late Spring or early Summer.

Cultivation

It is important that Primula Vulgaris be kept in cool and in good light. They cannot tolerate full sun in Summer. When the flowers eventually fade or the plant looks rather tired, it can be planted in the garden.

Tips

Keep the stems of cut Primulas from bending over, by inserting them in a tall narrow-necked vase, or tie the stems together below the flowers.

Care

In Spring remove dead and damaged leaves to prevent diseases. Yellowing of young Primula leaves may indicate a magnesium deficiency. To overcome this apply Epsom salts at the rate of 1/4 ounce in 2 pints of water.

Decorate

Primulas are good windowsill plants for cool, light position such as bedroom, kitchen or porch.

Humidity

Spray leaves in hot weather to help keep the plant cool. Stand the pot on a gravel tray or place it inside a larger pot filled with damp peat moss. Water the peat regularly but not to excess.

Soil

Potting compost.
