How to Grow Primulas Indoors

In early winter, cheery pots of primulas begin to arrive on store shelves. The fragrant, colorful flowers bloom on upright stems above the foliage, which is often hidden beneath the bountiful blooms. Resist the temptation to buy plants in full bloom; instead, choose those with lots of buds that are just beginning to open. Primulas last less than six months indoors, but you can transplant them into the garden after the flowers fade to enjoy them again next year.

Scissors (optional)
Liquid house plant fertilizer
Insecticide

Instructions

- 1
  Place the plant in a location with bright light but no direct sunlight.
- 2
  Keep temperatures between 50 and 70 degrees Fahrenheit. The flowers only last a couple of days in warmer temperatures.
- 3
  Keep the soil constantly moist. The leaves wilt quickly when the soil is allowed to dry out.
- 4
  Cut out the flowers at the base of the stems once the blossoms fade. Use scissors, or pinch them between your thumbnail and finger.
- 5
  Fertilize with liquid house plant fertilizer mixed at one-quarter strength.
- 6
  Pick off faded flowers to keep the plant looking neat and blooming longer.
- 7
  Watch for spider mites. These tiny pests are difficult to see, and the first evidence of an infestation is usually webbing on the undersides of leaves or yellowing leaves. Spray the plant with insecticidal soap or a house plant insecticide that contains neem according to the label instructions if you find spider mites on your plant.
