After the previous description, – about propagation- let’s list how lavender can be nurtured from a seed.
The multiplication of lavender, part 2:
Right in the beginning we can make clear, that this is the slowest and a less certain method of multiplication, because lavender germinates and sprouts in a protracted way and in a low ratio, however new specimens can be successfully nurtured by seed sowing, as well. Seed sowing is only possible in the case of lavandula angustifolia, which is the genuine, also called English lavender. Since the other hybrid lavender, known as an ornamental plant and also used for industrial production, lavandula x intermedia, being a hybrid doesn’t nurse seeds, so seed sowing is out of the question.
The hybrid lavender doesn’t nurse seeds
If we wish to sow lavender seeds in the spring, it’s worth using a trick, to achieve that the little lavender seeds sprout in a higher percentage ratio. We have to imitate a little winter, and this is not a joke. Snow is not necessary, only the other concomitant of winter, the freezing cold. So let’s put the seeds into the fridge for a few days.
Well, our test seed sowing, which took place in the beginning of a hot summer, was a complete failure. We didn’t try the freezing back then, yet. It also isn’t clear to us if during the freezing we need to put the seeds in the 0 F (-18 degree) deep-freezer, or just in the fridge. I think in the spring we will need a new trial, testing seed sowing with several versions. If we sow the seeds in the autumn, we don’t need to worry about the freezing procedure. It will relentlessly come during the winter. We should sow the seeds in a very shallow depth, in the spring 0,4-0,6 inch (1-1.5 cm), in the autumn 0,2-0,4 inch (0.5-1 cm) deep. It is worth leaving 6-8 inch (15-20 cm) distance between the rows, if we are sowing a larger area. We should condense the soil well, before and after sowing.
The autumn sowing will sprout very-very slowly in the spring until the end of April. If the sprouting came out dense, we should thin it out, when there are quite a few leaves visible on the little lavenders (we should replant the plucked out specimens). After the sprouting let’s not forget about watering. The little specimens with 4-5 leaves should be replanted, spread out for their further development, at least 2 inch (5 cm) away from each other, and when they reach the height of 6-7 inch (15-18 cm) we should prune them back by about half, so bushing can begin.
Even though our seed sowing wasn’t successful in the first round, we were surprised to find a little plant, that sprouted spontaneously from 5 seeds in the vicinity of one of our bushes in the rock garden, which we had replanted in the spring. So, it spouted by itself from scattered seeds, which were laying there even during the winter. So, if it was able to sprout without any help just ”by itself”, then the seed sowing should work, as well.
