Plant your Dahlia in a container in April
Dahlias are easy to take care of. It does not really matter in what kind of soil you plant them. They can be planted either in the garden or in a pot. Do make sure that excess water can easily drain away. Dahlia’s do not like having wet feet!
Dahlia’s do not like frost. They do not withstand it very well. That is why we plant the cuttings only after mid-May (after the so-called Ice Saints day). It takes a while for a Dahlia tuber to ‘wake up’ from its hibernation. How long that takes depends on the temperature and moisture levels (usually it takes between 5-15 days). So you can start by putting a Dahlia tuber in the soil. And then all you need to do is wait…Our advice
In April, plant your Dahlia tuber or cutting in a container and keep it inside below your window or in a greenhouse. It’s great to see from up close how the plant is growing. After a short while, your Dahlia will reach approximately 10 cm high. To let this grow into a plant that has a beautiful, broad shape, you can choose to pinch your Dahlia. Very simple: just cut back the tip of the plant and you’re done.
Dahlias require a fair amount of water. Especially the large, dark green varieties evaporate a lot of water. When you see soft and limp leaf or a hanging flower, don’t worry. Make sure you immediately water the plant once, and once again later. When you pay attention to this, your Dahlia will return the favor by producing masses of flowers!
Dahlias appreciate being fed regularly. Not too much, not too little. When you feed your Dahlia, make sure it contains kalium oxide (K2O) – this is important! When you give too much food (especially food that contains NO3), your plant will grow too tall and limp, which is not something you want. We also advise to use gardening or potting soil that already consists basic fertilizer.
