How to Raise Greenhouse Strawberries

If you live in a cool climate or want to grow strawberries year-round, they thrive in a greenhouse or indoors with the right soil, plenty of sun and proper care. June-bearing plants fruit once a year during that month. Ever-bearing varieties flower and fruit anywhere from two times per year to year-round. Strawberries do well in hanging baskets or a high, raised greenhouse bed for simple harvest and maintenance. Stackable growing pots allow you to grow vertically to save space.

Instructions

- 1
  Purchase your bed soil. Strawberries need a pH level between 5.3 and 6.5. Consult your local nursery on choosing the right soil and a controlled-release fertilizer.
- 2
  Trim the plant's roots to about 4 to 5 inches long. Remove any damaged roots, old leaves and runners. Soak the roots in water for one hour before planting.
- 3
  Fill your planter three-fourths full with soil. Scoop out a hole. Place the plant in the soil, placing its crown even with the surface of the soil. Spread the roots out. Place only one plant per planter. They need 2 feet of space around them to discourage disease and grow to their full potential.
- 4
  Place your strawberry plant in an area of your greenhouse where it receives six hours of sun each day. Water so that the soil is always moist to the touch, but never wet or dry.
- 5
  Pinch or cut off blossoms for six weeks after planting. This gives the plant time to establish roots before spending energy fruiting.
- 6
  Fertilize your strawberry plant once a month, then every 10 days when it begins to flower until harvest. Use high-potassium fertilizer.
- 7
  Pick your strawberries when they're red in color and glossy. Pick them in the morning, around 10 a.m.
