If you already have a greenhouse system, Strawberry production is a very logical way to increase your revenues and lengthen your season. Greenhouse growing Strawberry has many advantages and benefits such as increased yield, relatively easier pest management, as well as better fruit quality and quantity. The temperature of about 15°C must be maintained until the strawberry plants start to flower.

Types/Varieties for Growing Strawberries in Greenhouse

Depending on your needs and goals for growth, you should know that there are different many types of plants to choose from. Even if you grow strawberries in a greenhouse, it will never change the bearing times of the plants much. Therefore, picking or selecting the right type of plant is crucial for your year-round strawberry supply. If you just want to extend the picking season of the plant, you still may use seasonal plant types. They are listed below:

  • June-bearing strawberries

June bearers are just amazingly common and affordable. They provide the highest strawberry yields and you can easily achieve it over two to three weeks. They are commonly divided into Early Season, Midseason, and Late Season.

Early Season strawberries usually start fruiting in the late spring. Early Midseason strawberry varieties start fruiting around five days after Early Season varieties. Midseason strawberries start bearing fruits nearly in eight days after Early Season varieties. Late Midseason strawberry varieties will start fruiting in about ten days after Early Season varieties. Late Season strawberry varieties will produce their berries approximately 14 days after the Early Season varieties.

  • Everbearing strawberries

Everbearing strawberries do not bear the fruits endlessly. They usually allow only two harvests every year. It is also likely for a few of them to supply three harvests under excellent conditions. They put out very fewer runners than the June bearing varieties. They’re set using the hill system or in areas where space is brief.

  • Day-neutral strawberries

Day-neutral strawberries are unique. They’re going to produce a healthy harvest within the first year. They flower and fruit as long because the temperature is between 35°F to 85°F. Outside they will bear fruits from April until October. A greenhouse, however, can provide the right conditions for them to offer you a year-round supply. The main disadvantage of this variety is that they produce smaller berries than June-bearing and everbearing strawberries. These berries also are planted using the hill system a bit like the everbearing ones.

  • Strawberry runners

Strawberry runners also are called stolons. They’re parallel stems that spread above the bottom and make brand-new clone plants at nodes spaced with alternating intervals. This is often the rationale why strawberries are recognized as stoloniferous. The long and leafless stems between the mother plant, the plant-growing nodes, and therefore the growing point of the stolon are called internodes.

Adventitious roots give strawberries a plus over other plants. Strawberries are capable of propagating themselves through runners. This may let them discover better soil or spots with sufficient sunlight. Since strawberries never stop sending out runners, their beds need to be constantly thinned to take care of a healthy production

Suitable Soil for Growing Strawberries in Greenhouse

Strawberries do very well in nutrient-rich, well-drained, acidic soils that have high concentrations of high organic matter. You can fertilize your strawberry plant twice a month with well-balanced, organic compost throughout the growing period. The optimal and ideal pH should range between 5.5 and 7.0. You need to combine a layer of straw or mulch throughout the surface to keep the roots cool and free from moisture. Switch to a high potash liquid fertilizer right after they start to bloom out. This may maximize its fruit-bearing ability.

Suitable Temperature for Growing Strawberries in Greenhouse

Strawberry plants love to flower in cool to warm weather or climate. The temperature must not go over 25°C because higher temperatures can negatively impair the growth of the plant and kill the pollens. Keep the greenhouse temperature around 18- 25°C until they start flowering. Once you have picked the strawberries from the plant, you need to decrease the temperature inside your greenhouse so that it stays cold throughout the winter. A cool phase is more important to stimulate them to flower the next season. This is only matters if you choose June-bearing or everbearing strawberry plants.

In the first eight months or so, pick off all the blossoming flowers so the strawberry plants do not fruit. If you want to start growing strawberries from runners, make sure that to maintain proper humidity levels because runners are usually more sensitive to warm and hot temperatures than grown berries.

Red stele plant disease is caused by Phytophthora fragariae. It’s one of the foremost severe fungus diseases of strawberries within the U.S. This organism invades plants throughout winter until springtime. It’s very harmful in heavy clay soils soaked with water.
