Strawberries are a fruit which can be grown in a variety of different ways including greenhouses, hydroponically, in pots and in hanging baskets. Strawberries do best in moist soil well amended with organic matter and in areas of full sun. In a greenhouse, this light is supplemented by indoor garden lighting. Strawberries in greenhouses grow best in temperatures of 17.7 to 25.0 degrees C. A number of strawberry varieties have been identified as the most flavourful and productive for growing in greenhouses.
Jewel strawberries are cited as among the best strawberries for growing in greenhouses by the Cornell University Extension. The plants are compact with dark green foliage, and produce bright red, uniformly developed wedge-conic shaped fruit. Jewel is from the group of June-bearing, or early season, strawberry varieties. The plants produce high yields consistently, and the fruit displays a strong resistance to after-harvest fruit rot.
Tristar strawberry is one of the varieties which produces the highest yields and most flavourful strawberries in greenhouse production, according to the Cornell University Extension. These ever-bearing type plants produce large, juicy fruit throughout the year. Tristar strawberry plants do not stop their fruit production even during the colder and shorter days in spring and fall. The variety is one of the best for greenhouses since plants keep producing fruit straight through the winter in an optimal controlled temperature. Tristar plants continually set off sturdy runners and daughter plants as well, which flower and fruit even when they are not rooted in soil.
Guardian strawberries compare very highly with the quality and flavour of jewel in greenhouse production. Guardian strawberries are firm and large and plants produce prolifically. The strawberries are also resistant to a number of diseases common to strawberries. The plants grows to a mature height of 1 to 1 ½ feet, and have a moderate growth rate. Plant in moist soil in the greenhouse and ensure adequate lighting for optimal growth.
