Good to know about Begonias
Begonia is a very large genus with approximately 900 species. Tuberous begonia is a very popular and richly flowering summer flower available in many colours.
Planting
You will achieve the best results by pre-sprouting your begonia tubers in pots with good, light, moist potting soil in April.
Care
Around June 1st, depending on the weather, plant your begonia plants out in the garden, after which they will begin to flower. Flowering will continue until the frost sets in later in the season. Begonias thrive best in sun-partial shade, but can also be planted in slightly more shaded conditions.
Wintering
You dig up your begonia tubers in the autumn, where they should be stored frost-free. Store them either in dry sphagnum moss or in a paper bag.
Gladiolus
Worth knowing about Gladiolus
Gladiolus is a large genus, growing naturally in Africa, Europe, and Asia. Most and best known varieties come from South Africa. They are showy flowers in vibrant colours, most often seen in autumn bouquets.
Planting depth and soil
In Denmark, they are grown outdoors. Gladiolus corms are planted in good, porous, and nutrient-rich soil. They are planted in a warm location in the garden in May. Plant 20-30 cm deep.
Overwintering
The warm location can be central to overwintering. The better and warmer the location, the greater chance your corms have of overwintering in the garden. If you want to be completely sure to have them for several years, they should be dug up in September-October, placed in a bucket or box until the top dries out. Then, the dry top is cut off, and the corms are stored in a box with sand or paper bags over the winter in the basement until next spring.
Different gladioli
Depending on the weather, your gladiolus corms will take 80-100 days from planting to flowering. They are also considered deer-resistant. There are many groups of gladioli: large-flowered, butterfly-flowered, as well as nanus or colvillii hybrids which are shorter. Additionally, there is a species, Gladiolus byzanthinus, which grows wild in Southern Europe and North Africa. This is often found in our autumn assortment of spring-flowering bulbs.
Kanna, Canna
Worth knowing about Kanna
Canna is one of the most flamboyant summer plants in the garden. It originates from tropical and subtropical America and should be treated accordingly. Canna has beautiful exotic and brightly coloured flower spikes, either in solid colours, bi-coloured, variegated, or with dots and spots, with green or brownish, coppery leaves. It grows into bushes from 60 cm up to 2 meters or more in height.
Planting
Canna is pre-cultivated indoors from April and planted out in a sunny, warm bed or in pots around June 1st, depending on the weather.
Care
They should be well-watered and fertilized and must not dry out. They can tolerate slightly moist conditions near a garden pond or in a sunny bed in the garden.
Wintering
Around October 1st, the tubers are dug up. If they are potted in smaller pots, these can be brought indoors. Here, the soil should dry out and the plant tops wither. After withering, the tuber/pot is overwintered in a frost-free basement or a frost-free outbuilding.
