Growing cyclamen outdoors will give you colour in late autumn when all your autumn flowering plants are starting to die back, some cyclamen varieties will flower all winter.
There are many cyclamen varieties, I opted for winter flowering ones to get some colour over the winter months. You can also buy indoor cyclamen varieties to keep as house plants, but this of for another article.
Cyclamen can be grown from seed or tubers, but it’s easier to buy a plant from your local supplier as they can be tricky to propagate.
If growing from seed, the seeds should be soaked overnight once collected. Immediately after soaking, they should be sown in the soil with a thin layer of compost to stop light from affecting germination. You must also be aware of the right temperature to prevent them from dying. The recommended temperature for cyclamen seed germination is around 16-18 degrees.
While germinating, you must cover your seed tray in a clear plastic bag to great some humidity, placing it in a cool dark location.
If you are looking to buy cyclamen plants, most good garden centres and nurseries will stock them. I bought mine at Shincliffe Mill Nursery (County Durham) during the autumn, they had a whole enclosure dedicated to them.
Outdoor Cyclamen Planting & Maintenance
Cyclamen are fantastic at thriving in the shade, I have a couple in pots in a very dark and damp spot in my north-facing garden. They receive very little light and have been flowering for months, hopefully, this will continue over winter.
Cyclamen also do well planted under trees as they don’t like heavy rain. In autumn I planted three under my cherry blossom, all have been flowering well so far.
Outdoor cyclamen are easy to maintain and do not require watering, as long as you receive some rainfall. Simply plant in your required location and add some compost around the base of the plant. If planting in pots and containers or hanging baskets, John Innes No 2 potting compost is recommended with some gravel/perlite to help drainage. You could also include some slow-release feed pellets to help them through the winter months.
Cyclamen will thrive with regular deadheading; flowers can fall and become rotten, which can affect the plant’s tuber.
Cyclamen Growing Problems
Just like other plants, you may encounter problems when growing cyclamen plants. Here are some of the problems we can expect to happen:
- Moulds and fungi can develop on these types of plants. Keep your eye out for a grey fuzzy mould which is cyclamen grey mould. It can spread to the stalks and leaves which can cause them to collapse. To avoid this mould, remove dead plant material regularly and ensure good airflow if kept in a greenhouse.
- Cyclamen plants are prone to rotting especially when they are exposed to moisture. Because of this, the temperature becomes cool and the air circulation becomes restricted. The rotting is usually observed at the base of stalks and spreads to the flower buds and leaves. When this happens, the affected areas should be removed ASAP.
- Plant pests such as red spider mites can cause problems if growing under glass. Although they are very small to be seen by the naked eyes, they can be observed when you notice yellow or deformed leaves. To avoid these pests, you must place the plant in a well-humidified environment.
If you fall in love with cyclamen, you can plan your varieties so you have cyclamen flowers all year round. Each variety has has its own colour ranged and flower shapes, all these below are considered hardy.
