Plant early – to get container plants off to a good start, you have to plant early. You cannot expect to plant them in the winter and see them thrive. According to expert gardeners, container plants need at least a month of warmer weather. It is good to start them in the autumn so that they can establish their roots before freezing weather sets in.
Pick the right pots – there are many pot types you can pick from. Resist the urge to go with beautiful clay or concrete pots. These absorb a certain amount of moisture, which can freeze in low temperature and thus crack the container. Plastic and resin are much better in that regard since they retain no moisture and those will not break or crack in the winter weather.
Don’t forget to water potted plants – winter damage most frequently occurs due to desiccation (drying out). You must not forget to water containers when they are dry, especially before you expect a hard freeze. It is best to water in the morning because that is when the soil is warming up.
Plants need good drainage – when you water plants, you have to ensure the water drains properly. Otherwise, it will accumulate, expand and possibly break the container. The planters need to have drainage holes and well-draining potting soil. Also, don’t let plants sit in a tray of water, as most winter plants don’t like soggy conditions.
Pick your plants wisely – container soil can get colder than ground soil, so it is important to select plants that do well at least one zone colder than the area you are located in.
Placement is essential – although sunlight is rather weak in the winter, you should still locate your potted plants in the sunniest possible spot. Also, make sure they are away from any strong winds that can dry the plants or topple over the pots.
Protect pots – group your pots together for better protection and place them against a sheltered location. You can also wrap them in burlap if you suspect winter weather can cause them some damage.
Feed them slowly – one thing you should know about plants in the winter is that they actually absorb fewer nutrients then. Don’t even try to overwater and overfeed them – it won’t help them one bit. What you can do for them is use enriched soil and a well-balanced organic fertiliser when you plant them. This will give them a good supply of nutrients for the winter.
