Planting the dahlia
Properly planting a dahlia is important because this step determines the good growth and flowering of your plant.
Planting dahlia bulbs:
This is the most common, easiest and fastest planting technique for beautiful dahlia flowers.
- The tuber (bulb) of the dahlia is ideally planted in April and May , after all risk of frost.
- The dahlia likes rather rich and well-drained soils.
- Plant them at a depth of about 10 cm, respecting a spacing of 80 to 100 cm between each tuber, because the dahlia needs sun and likes to be at ease!
- The shoot should be directed upwards.
If you think your soil is poor, do not hesitate to enrich the soil at planting with an organic amendment or compost.
The sowing of dahlia is quite possible but this technique requires a certain know-how reserved for insiders.
- In sowing, prefer sowing in a terrine from the month of March, transplant in April and put in the ground in May.
- Multiplication by division of dahlia tubers in spring.
Once in place, the dahlia requires relatively little care even if a few gestures will allow you to prolong or improve flowering.
- Remove faded flowers as you go.
- Once the stems are completely faded, cut as short as possible.
- Dahlias resist temperatures of around -5 to -10°.
The dahlia is quite resistant but will gladly appreciate being watered in periods of prolonged drought.
Take care that the dahlia bulbs are never flooded, no standing water, because they could rot.
Well-drained soil is the guarantee of avoiding this kind of unpleasant surprise.
- Water the dahlias without wetting the foliage. This will avoid any risk of illness.
- Water preferably in the evening to avoid evaporation and also save water.
Making dahlias bloom longer:
It is possible to extend the flowering of dahlias beyond summer, sometimes even until the end of October.
- Apply fertilizer for flowering plants once a week until the end of flowering.
- Remove faded flowers as you go to avoid exhausting the dahlia and encourage the arrival of new flowers.
Dahlia in winter
While dahlias can be left in place over winter in areas with mild winters, they cannot withstand severe frosts .
If you live in a region where the temperature frequently exceeds -5°, you must at all costs bring in the bulbs before the first frosts.
- Wait until the foliage is completely withered and cut 10 cm from the ground.
- Pull out the rhizomes and let them dry.
- Clean them with a brush.
- Keep them cool, dry and protected from light.
- Replant them after all risk of frost, in the spring.
In other regions, simply protect your tubers with a mulch of dead leaves, for example.
