Considering that we British are hailed as being a nation of gardeners, its extraordinary that we seem to have forgotten the original reason for building a conservatory - to grow exotic plants. Nowadays, we tend to buy conservatories to provide an extra room so if you intend to keep plants in your conservatory, you need to let the supplier know.
The first thing that must be considered is ventilation. Conservatories can get hot; very hot. The best advice is to have ventilation vents in the apex of your conservatory, however, leaving the connecting door between the conservatory and the house open during the summertime will allow for air circulation. If you choose to do this, ensure that your conservatory door is securely locked.
The ideal temperature for a plant-conservatory is a winter minimum of between 7C and 10C, so slightly cooler than for a conservatory used as an extra room.
Temperatures in this range will allow you to overwinter summer garden plants, such as pelargonium, and grow flowering winter plants - cyclamen and azalea spring to mind. A conservatory is far more stylish than a window sill!
Ensure that your conservatory plants receive enough water by checking them daily; if the top soil feels dry, water the plant. And remember that just wetting the surface is not good enough, the soil should be moist right down to the bottom of the pot.
In the spring and summer months, your conservatory plants should be fed weekly, reducing to once or twice a month in the winter months. Make sure that you use the correct feed too - for instance, citrus trees do best if they are given a specific fruit and citrus food.
As winter comes to an end, check all your plants to see if they need repotting - which is best done in spring or summer. And if your plants are taking over or are not growing straight - prune them! The best time to prune is after flowering or in later winter/early spring.
Finally - think about pests. Winter fungal diseases can be a major problem in cool conservatories but can be kept at bay by using a small dehumidifying unit.
Next time, we’ll take a look at specific conservatory plants and how to get the best out of them.
