Actually, the French lavender impresses with its extraordinary flowers. But what to do if there is no flowering? We have advice for you.
The French lavender (Lavandula stoechas) attracts attention with its colored, large bracts at the top of the spike-shaped inflorescence and is a delight in the home garden. Different varieties cover a wide color spectrum that includes white, light pink, purple, blue and violet. It clearly distinguishes itself from many other types of lavender by its floral decoration and thus secures its place in the bed or on the balcony. And it actually blooms abundantly and for a long time. Until August or even September, it delights with its blooms. In the following, we explain what can be the reason if there is no flowering.
The French lavender is actually known for its lush flowers. But sometimes he just doesn't want to and only a few, small or none of the decorative inflorescences appear. This can have various reasons and is quite avoidable. Here's a little analysis of why the lavender doesn't bloom.
French lavender not blooming: The wrong location
In contrast to most other types of lavender, French lavender prefers sandy soils that are poor in lime. If the subsoil is too calcareous, this can lead to stress and reduced flowering power of the French lavender. Then there is no real alternative other than transplanting. The French lavender also grows well in pots: mix organic herb and seed soil with sand in a ratio of 4:1 and keep the substrate evenly moist, but not wet - in a sufficiently large container, this ensures lush growth and rich flowering of the French lavender.
French lavender not blooming: too few nutrients
The French lavender does not need much fertilization, but if there are too few nutrients available for the mint family, this can be at the expense of the flower. However, a short-term re-fertilization can help and theGet blooming going again quickly. However, in order not to risk the lack of flowering in the first place, we recommend fertilizing with our primarily organic Plantura organic universal fertilizer, which makes frequent re-fertilizing unnecessary thanks to its long-term effect.
French lavender not blooming: Too little pruning
If the French lavender has not been pruned for a long time, the shoots are very woody and several years old, this can be a reason for few inflorescences. If the optimal time for a shape cut with the new growth in spring was missed, a summer cut can also be carried out until July. The shoots should be cut off a few centimeters at the top. The newly emerging shoots are young and fresh. Here the colored inflorescences of the French lavender form earlier and in greater abundance.
Tip: Remove the dead lavender inflorescences immediately - this can prolong the flowering period.
