Flowers will appear within 3-4 weeks and because of the closed environment you will need to pollinate them by hand using a soft haired brush or even a feather, because there will not be any flying insects inside the greenhouse to pollinate the flowers naturally.The first fruits should be ripe by mid April – a full 6 weeks ahead of the outdoor season for strawberries.But you must be very vigilant in watering as there isn’t a great depth of compost for the plants to use. You can also use proprietary bags of compost – 60 and 80 litre are ideal – and simply cut holes in the bag yourself; because the volume of compost is greater than with growbags I often feel these are a better option although a little more expensive.Are a wonderful and novel way of growing strawberries!Additional advantages are that the fruits hang temptingly down over the sides of the basket – a most attractive sight – and they keep clean with no soil-splashes, bacterial and fungal diseases tend to be kept at bay because the air circulation is better, and the plants and fruits tend to be troubled less by slugs. You must be very vigilant in your watering, every day at least, or even twice a day, once in the morning and once in the evening, for really good results.Of course aerial containers such as this are very susceptible to drying out and the strawberries must have adequate moisture to develop the best, most plump berries, as well as to maintain the health of the plant.Is a good way of encouraging early ripening from established outdoor plants.
Any strawberry varieties will grow well in containers but to make recommendations I would probably discard those taller and more rangy growers as they will become very untidy in containers and the rich compost can actually encourage even taller growth!
Pot the plants individually in 10” pots, using a good proprietary general purpose compost, watering well of course and place them in a greenhouse with a heater thermostatically controlled to maintain a minimum 50 degrees overnight and a gently agreeable 60 degrees during the daytime.
The plants will start to make active new growth almost immediately and after 2 weeks or so start providing additional foliar feed.
Perhaps you wish to keep your strawberries close at hand, on the patio or terrace, or even by the door.
Practically any container can be utlized provided it has a minimum depth of around 12”.
