Dahlia Labyrinth

During their growth, Dahlias need moderate but regular watering. The soil should be moist, but not waterlogged, to prevent the tubers from rotting. Regarding fertilization, it is best to start with fertilizers higher in nitrogen to support foliage growth. Just before the buds form, switch to a fertilizer with a higher potassium content, which will ensure vibrant colors and rich flowering.

Dahlias cannot tolerate frost, so plant the tubers outside only in May or early June, when there is no longer a risk of late frosts (often waiting until after the 'Ice Saints'). Place the tuber horizontally in the ground at a depth of 10 to 15 centimeters so that the eye, or stem germ, is pointing upward. Then, cover it with about 5 centimeters of soil. When planting, keep a spacing of 30 to 50 centimeters; you can expect to fit 1 to 4 plants per square meter.

No, Dahlias are not frost-hardy in our conditions and would not survive in the ground. As soon as the first autumn frosts burn the above-ground part of the plant, it is time to carefully dig up the tubers with a spade. Clean them of soil, let them dry thoroughly, and then store them in a cool, dark, frost-free room. It is ideal to place them in a crate with sand or sawdust. Check them occasionally during the winter to ensure they are not starting to mold or, conversely, drying out too much.

Yes, sturdy support is an absolute necessity. The 'Labyrinth' variety is very tall, reaching an impressive height of 80 to 160 centimeters. Furthermore, it produces heavy, full blooms that could easily snap in rain or strong wind. It is ideal to drive solid stakes into the ground early and use twine to securely tie up the entire bush.

Certainly! Starting them indoors is a great way to speed up the blooming of this beauty. You can plant the tubers in pots at home as early as March and place them in a bright, frost-free location at room temperature. You can then transplant them outside to the flower bed, complete with their root ball, in May; by then, the plant will be strong and will delight you with its first flowers much sooner.

Yes, we highly recommend pinching. As soon as the young plant has several pairs of true leaves, pinch off the terminal shoot. This will force the plant to create side shoots, resulting in a compact, bushy plant. During the season, don't forget to regularly remove faded flowers. This prevents the plant from wasting energy on seed production and encourages the development of many new buds.

In general, Dahlias love full sun. Choose a spot for them that receives direct sunlight for most of the day. In the shade, the plant will not bloom well and will stretch out in search of light. The soil should be very nutritious, rich in humus, and at the same time well-drained so that water does not stand in it for long periods.

Growing in containers is possible, but the 'Labyrinth' variety is a major challenge due to its height of over one meter. It requires a truly large and heavy container so that the plant, along with its support, does not tip over in strong winds. Furthermore, the substrate in a pot will dry out much faster, so much more frequent watering and more diligent fertilization are necessary. Although shorter cultivars are better suited for containers, with good care, this plant can manage it too.

There are two proven methods. Tuber division: Simply divide a large clump in the spring before planting. It is essential that each separated piece of tuber has a 'neck' with an 'eye' (bud) from which the new plant will grow. Let the cut surfaces dry or treat them with charcoal. Cuttings: In February or March, place the tubers in a warm spot to sprout. Once the shoots are 5-8 cm tall and have two pairs of leaves, cut them off, dip the end in rooting hormone, and stick them into a light, moist substrate, where they will root beautifully with regular misting.

The 'Labyrinth' variety is absolutely phenomenal for cutting in both wedding and autumn bouquets. Harvest the flowers when they are about three-quarters open, as they will not develop further in a vase. Check the back of the flower, where the petals must be firm. For maximum longevity, which is usually around one week, immerse the ends of the stems in hot water at 70 to 80 °C for 15 minutes after cutting.

It could be the much-feared mosaic virus. This disease causes leaf deformation, significant color changes, stunted growth, and dwarfing of the entire plant. Unfortunately, this viral disease is incurable, so you must immediately dig up the infected plant along with its tuber and dispose of it completely. Never put it in the compost, as the infection could spread. The virus is often transmitted by pests such as thrips, so check your plants preventively.

Slugs and snails absolutely love young Dahlia shoots and can destroy the plant right at the beginning of the growing season. Keep a close watch on your plants. If regular manual collection in the evening or standard mechanical barriers around the bed do not help, it is often best and gentlest to reach for eco-friendly products based on iron phosphate, such as Ferramol.

This stunning variety produces huge, beautifully structured flowers. You can look forward to an indescribable blend of pink and orange shades, specifically transitioning through tones of vibrant bubblegum, light pink, deep salmon, and apricot. For many gardeners, this variety beautifully symbolizes autumn, and its blooms are beloved by florists as a centerpiece for autumn wedding bouquets.

There can be several reasons for this, but the most common are a lack of sunlight or an excess of nitrogen in the soil. If you use fertilizers with a very high nitrogen content in the summer, the plant invests all its energy into growing huge leaves but neglects flowering. Before buds form, it is therefore necessary to switch to fertilizers with a higher potassium content in time. Regular deadheading of faded flowers also plays a role.
