HOW TO KEEP YOUR CONSERVATORY WARM IN THE WINTER
Low heating is the obvious one, but make sure it is consistent. If temperatures fluctuate too much, with sudden bouts of dry air, house plants will suffer. To combat the dry air, many plants need misting regularly, or pebble trays can increase humidity.
Double glazing solar glass is a great way to regulate the temperature of your conservatory, particularly when there is no central heating.
Draft-proof your conservatory by making sure vents can be covered while windows and doors are sealed properly for the winter period. A lot of plants will not tolerate drafts, particularly in the winter months, so consider the placement of them.
Flooring in your conservatory will have an impact in overall temperature, so if you wish to increase the temperature without strong central heating, then invest in rugs or carpets to treat it more like a room in your house. If the floor is cooler, then plant stands are a great way to raise them off the cool floor.
Blinds will add a level of heat protection, but also shield your plants from harsh rays, if you have picked plants that do not tolerate full sun.
