So that the blood flower can develop well and receive sufficient nutrients, you must repot it occasionally. When is the best time to do this and what do you have to consider when repotting blood flowers?
When and how should you repot a blood flower?
Repotting a blood flower should be done in early spring when the bulbs have taken over the pot or roots are growing out. Choose a suitable pot, use compost-based potting soil and place the onion tops uncovered in the substrate. Do not fertilize for several weeks after repotting.
The Best Time to Repot Blood Flowers
It's time to repot when the bulbs of the blood flower have taken over the entire pot or roots are already growing out of the top of the container.
Repotting takes place in early spring.
The right pot
The new pot should not be too big, as the blood flower will then put all its energy into forming new bulbs. There should be three to four centimeters of space between the onion and the edge of the pot.
If the current pot is still sufficient for the size of the bulbs, you should remove the top layer of the substrate and fill the container with fresh soil. This means the onions are protected and do not have to recover from repotting.
Which substrate is suitable for the blood flower?
Compost-based potting soil (€12.00 on Amazon) is suitable as a substrate. The pH value should be around 6.
Repotting the blood flower properly
- Carefully remove the onion from the old pot
- if applicable. Share onions
- Shake off substrate
- prepare new pot
- insert onion
- cover with soil
- Leave onion tip uncovered
- pour on
- warm and bright
Plant the blood flower bulbs so that the tip still sticks out of the substrate. Do not completely cover them with soil.
After repotting, you must not fertilize the blood flower for several weeks, as the fresh substrate provides it with optimal nutrients.
Don’t share onions too often
If you repot the blood flower, it is a good idea to divide the bulbs to grow offshoots. To do this, carefully separate the small onions.
When dividing, only choose onions with the strongest possible shoots.
You must not share the blood flower too often. The shoots then remain weak and no flowers form. Therefore, wait three to four years before dividing the blood flower again.
Tip
The blood flower cannot only be propagated by dividing bulbs. Propagation is also possible by sowing. You can harvest germinable seeds from existing blood flowers in spring.
