The Dahlia
Below you will find some general information about the range, cultivation and certification.
For a complete overview, please see our catalog.
These Dahlia are tremendously important for the insects. Bees and butterflies go nuts about dahlia’s! The more compact varieties are well equipped for the potculture and all are great for borders, public greens, municipal gardens , schoolgardens etc.
These dahlia will develop flowers continuously, I have selected them for just that… And, mostly from own breeding!
This Group of Dahlia are super and especially selected for the cutflower grower.
They will flower deep into the fall en have a good vase life.
We propagate our dahlias ourselves using completely organic methods. We are a rare breed of dahlia growers. The first to be a 100% organic on a professional scale! Our bee- and butterfly-friendly dahlias are bred in-house and are organic from seed to tuber!
The cuttings we take are heel cuttings, which include a small piece of the mother tuber’s collar. This ensures good tuber formation, resulting in beautiful, healthy plants. This contrasts with plants you find at garden centers: these are often taken from a top cutting and produce a tuber of inferior quality, or none at all.
The quality of the mother tubers is monitored by the Flower Bulb Inspection Service (BKD).
The SKAL inspector annually checks whether we meet the requirements for certified organic production.
Growing cut flowers is slightly different from growing tubers, and each grower approaches this slightly differently.
Of course, the important thing is: when do you top the plants? Some growers do this at two pairs of leaves, others at four.
The density of plants also varies considerably: from 23 plants per m² to 12 per m². Planting thicker makes the plants taller. This makes cutting easier and allows for a higher number of stems to be harvested.
Growing dahlias in pots is also different from growing them in open ground. You start with a potting soil with an EC of 1. The trick is to maintain this EC level. The nutrient mix is, of course, important. During the vegetative phase, the plant requires a relatively high amount of N (nitrogen), later requiring a higher percentage of K (potassium).
To limit insect damage, first ensure healthy growing plants. Additionally, spray plant strengtheners (compost tea, herbal extracts) and insect repellents such as neem oil and essential oils.
Healthy soil is the key to success here. Mulch the soil and fertilize where necessary. The nutrient mix is, of course, just as important in potted plants.
Unlike potted plants, the nutrient buffer is larger in the garden, making cultivation somewhat easier.
SKAL (organic cultivation certification). Skal annually inspects the input of the cultivation methods and resources used at the nursery.

BKD (plant health/plant passport). The Flower Bulb Inspection Service annually inspects the tubers we use for propagation (the supporting tubers) for health.

NAK (plant health AM-free certificate). Every flower bulb in the Netherlands must be grown on soil free of potato fatigue. A certificate is issued by the NAK, which is then inspected by the BKD.
Tip!
Plant a dahlia in a pot (tuber or cutting) in April and place the pot on your windowsill or in your greenhouse! It’s fun to watch this growth process up close. After a while, a plant will have grown to about 10 cm tall.
To obtain a beautiful, spreading plant, you can choose to top the dahlia. Simply pinch out the top and you’re done.
