Need help on how to plant Cactus Dahlias? In this blog, we’ve compiled a guide full of tips and advice on planting, arrangement, and aftercare for your Cactus Dahlias, to allow you to get the best performance from your plants.
This special, eye-catching variety of Cactus Dahlias are distinctive by their unusual shaped summer flowers, which look fantastic planted together for colour bursting garden displays and borders, as well as when planted as a standalone item. They can flower until Autumn and have a wide range of interesting varieties, all with very showy flower shapes and rich colour shades.
Dahlia tubers can be planted 10cm deep in fertile well drained soil, outdoors in spring when the frost has disappeared. If you plant before the frosts are over, they may get frosted and die, so pot in March or early April for flowering in early July. They prefer to be in a sunny location and spaced at approximately 45cm apart.
Dahlias start blooming about 8 weeks after planting, starting in mid-July.
Some gardeners start tubers indoors in containers a month ahead to get a jump on the season.
In this video tutorial, our resident gardener Jeff covers how to plant Cactus Dahlia tubers in to pots and shares helpful tips and advice on how to achieve the best results out of your Dahlia plants.
There’s no need to water the soil until the dahlia plants appear; in fact, overwatering can cause tubers to rot. After dahlias are established, provide a deep watering 2 to 3 times a week, preferably more in hotter, dry climates.
In areas where there is extreme cold, dig up dahlias and store in a cool peat over the winter and then replanted the following year.
Apply a high potash fertiliser every few weeks in the summer to help growth and they can be dead headed when necessary.
Fritillaria are a stunning accompaniment to any garden display with their elegant drooping bell-shaped flowers that are particularly effective when grown in groups, as well as being versatile enough to add charm to rockeries, borders, flowers beds or even on the patio in pots. Our extensive range of Fritillaria includes smaller varieties such as Fritillaria Meleagris, which produce a mixture of white and purple flowers, and taller varieties such as Fritillaria Imperialis and many bi-colour favourites such as Fritillaria Uva-VulpisandMichailovski.
Our beautiful Fritillaria bulbs flower between April and May in the spring, and our bulb sizes vary between 5cm up to 24cm, with certain varieties growing up to 120cm. They can be planted at 8-10cm deep and 10-15cm apart in well drained/light and moist soil. They can be planted in areas with full sun access or preferably with partial shade, and can be left to naturalise in grass, borders or even cold greenhouses. Fritillaria are very hardy and are an excellent choice for border displays, rockeries or for woodland areas, where their elegant drooping bell-shaped flowers are likely to add that little something different to your garden.
In this simple how-to video tutorial, our resident gardening expert Jeff shows you how to plant Giant Fritillaria with tips and tricks for getting the best results out of your bulbs!
When established in the right environment you can easily begin to see fritillaria plants multiply. In good growing conditions crown imperials will readily form large clumps. If a well-established colony begins to flower poorly then lifting in early autumn when dormant, thoroughly improving the soil and replanting, or moving to a new site may be enough to restore satisfactory flowering. The bulbs may take a year or two to re-establish.
