Taking cuttings in water is a simple technique to multiply your plants but it doesn’t work for all plants. It is best to choose the end of the stem which has no flowers, then cut it under a knot as that is where the new roots will sprout. Remove a portion 10 centimetres long, or longer if you want to put it in a taller jar. For it to succeed, choose a wooden branch which is not completely formed, as this will help the cutting to insert itself.
The best time for this operation is between April and September, whether for a herbaceous cutting or not. Once the cutting is removed, get rid of the leaves at the bottom of the stem and leave only 2 or 3 at the top. If these are big leaves, cut them in half to limit evaporation.
Fill a clean recipient with rainwater and add a small piece of charcoal to ensure that the water remains clear. If you don’t have charcoal, change the water every 15 days. Then insert your cuttings, leave the recipient in a bright place and wait! The amount of time needed for the appearance of roots varies with the type of plant. If you notice the leaves falling and the cutting starts to rot, take it out of the water – it hasn’t worked this time.
When the roots have grown to 2 or 3 cms., put the cutting in soil. Choose a light soil so that the cutting can adapt rapidly to its new soil and growing conditions.
Taking Papyrus Cuttings
This can be done in water but the method is a bit different. Cut the umbel of your Cyperus and plunge it upside-down in a jar filled with water. Roots will form on the extremity. Then replant the cutting in a flower pot.
