A successful way of bulb multiplication is by TWIN SCALING. This is particularly successful with Liliums. The bulbs you use must have a basal plate and must have scales similar to an onion.
The best procedure to follow is:
Start a few months before the planting time of the particular species you are using.
Sterilize the bulbs in a bleach solution (1 part bleach) [household bleach will do] to 10 parts of water for about five minutes.
- Then wash bulbs in clean water.
- Cut off a third (top) of the bulb.
- Cut the bulb down the centre, top to bottom, four times until you have four quarters.
- Separate two outer scales per section from the inner scales, without breaking them off the basal plate.
- Using a knife or scalpel, cut off two scales with some of the basal plate still attached.
- Keep doing this until you have many separated sections.
- Place the portions in a bleach solution (as described earlier) for about thirty minutes, stirring gently.
- Drain and dry off on paper or other material.
- Sterilise Vermiculite in the oven at 230 degrees Celsius for about 30 minutes and allow to cool.
- Add water to the cooled Vermiculite to moisten it (don't make it too wet) and put it in a plastic bag and add the cut pieces.
- Squueze as much of the air from the bag as you can.
- Put the bag in a cool, dark, place and keep temperature at about 22 degrees Celsius.
- After a period of time, bulbils and roots will have formed.
- Plant them and wait for them to grow.
Bulbs that can be twin-scaled are
- Lachenalia Veltheimia Narcissus
Many growers have successfully used this method.
It is not too technical and satisfaction can be achieved by this method.
A perfect way to increase your plant stock!
