watering
Primrose plants (Primula vulgaris 'Kerbelcob' BELARINA COBALT BLUE) require well-draining soil and enjoy having consistently moist soil. Water these plants regularly and evenly – about once every week when temperatures are high. During the cooler months, these plants only need to be watered every 10-14 days. Be careful not to overwater, since this can lead to root rot or powdery mildew. In order to determine whether or not the soil needs water, take a finger and lightly touch the soil. If the surface of the soil is dry, then it's time to water. Finally, make sure that the plant is in a sunny spot and place water at the plant's base, avoiding the foliage.
sunlight
Primrose (Primula vulgaris 'Kerbelcob' BELARINA COBALT BLUE) prefers bright, indirect sunlight for 4 to 6 hours a day, which is best provided by placing it in a south or east facing window. It is important to make sure that the sunlight does not touch the foliage directly as it may cause burning. During the summer months, it may be beneficial to move the primrose to a lightly shaded spot during the afternoon and mid day sun, as this will help to avoid scorching or wilting. In the winter months, the primrose can remain in the same spot as long as it is receiving enough sunlight to keep its foliage looking healthy.
pruning
Primrose should be pruned annually. Pruning should begin in the spring when new growth begins to appear. To encourage a more compact shape, pinch back the top and sides of the new growth before it flowers. Deadheading should also be done to promote more blooms. Once flowering has finished, cut the stem back to just above where the leaves emerge from the stem. This will promote more compact growth. Additionally, if the plant has become leggy, then it can be cut back by up to 1-third to encourage new growth and prevent flowering.
