Q.Lavender
I have Lavender in the garden, it is angustifolia. The last years it stayed upright and looked good. This year I had cut it in spring and after that the plant exploded. It is right under a tree. Now the stems are very long and they tend to lie on the ground. Was it wrong to cut it or what is the reason for it? What can I do?
Another question: can I use a foliage to prevent weeds? Or is it bad for the roots of lavender? Is it possible that the colour of the blossoms (Lavender) is fading? Has it something to do with the nutrition?
Best regards

Cutting lavender in the spring is a good thing to do, so that's not the problem:

If you added any fertilizer to the lavender, especially nitrogen fertilizer, that could be the culprit. Nitrogen promotes fast and often weak growth in many plants. Strong wind could also cause plants to flop over.
If not, the plant is probably healthy but just a fast grower. You could harvest the lavender more often, then use the stems for decoration or for their pleasant scent.
If the blossoms are fading, that may just be the end of the season coming on.
