Lavender propagation, my 3 methods:
- in a heated propagator inside;
- in pots with cutting soil outside on the terrace;
- and directly into the soil on the land.
See my see my previous blog. It is time for the results.
Lavender propagation indoors in a propagator
Lavender propagation with the propagator inside was not a success. Very soon it started to get mouldy. I turned off the heating and removed the lids, but the remaining cuttings didn’t like it either. Of the 100 or so cuttings, three are left. After a while I put them outside because it was clear that they craved light. They became long and thin while the outside specimens looked a lot sturdier. I carefully let them get used to outside and after a while they also became firmer.
Lavender propagation outside in pots
The planters with the cuttings outside on the terrace were in the shade with only a little sun in the morning with just like the cuttings inside a carefully chosen mix of cuttings soil clearly did better, but at least half did not root. The ones that survive don’t look very good compared to the ones on the land.
Lavender cuttings directly in the ground
The big winner is cuttings directly into the ground. In my case in Spain with a shade cloth that blocks 70% of the UV radiation. That soil was tested beforehand as relatively poor and therefore suitable for lavender. Except that the PH value at that time was not yet increased with lime. From March the cuttings suddenly started to sprout a lot. Not all the same, but per type of lavender. Apparently one goes faster than the other. I haven’t exactly kept track of it, but I think about 90% is doing well to excellent. Soon I hope to plant them out, I think around May. I’m curious how they will experience the summer sun in Spain, that’s why I bought some extra shade cloth just to be sure.
New spring lavender cuttings
Last week I pruned the plants and made cuttings again. Now only directly into the ground in the same way as last time. The fourth week of April is a bit later than I had hoped and that’s because the temperature in my region has been relatively low in recent weeks. While northern Europe was already almost in summery atmospheres we got an unprecedented amount of water. That is fantastic for the nature. But I thought it would be better for the cuttings to start a little later.
Update: early April 2022
Early spring is cold again in Spain. And we finally had rain! Soon I will take cuttings from my very best lavender plants again. Taking cuttings in April and planting them out in November seems to lead to the best results here in Spain. Plants planted in spring are clearly less vigorous than those planted in autumn. Not surprising really. Soon after planting, they start to flower. This does not seem to me to be conducive to root growth.
What are your experiences with taking cuttings from lavender? When do you plant out the young plants?
