In autumn, it's very important to keep the proper light, because lavender has high requirements for light, which can neither be too weak nor too strong. Therefore, avoid direct too strong light in the early autumn. At the end of autumn, sufficient light should be provided. Even in the coming winter, it is possible to provide all day light
Lavender itself likes a slightly dry environment and is afraid of waterlogging. Therefore, when replenishing water in autumn, we should pay attention to wait for the soil to dry before pouring. Note that each time pouring, do not half through, it is better to fully through, but do not water.
The most suitable range is 15 to 25 degrees. The temperature should not be too low at the end of autumn. Lavender will be dormant under zero.
Lavender flowers mainly in summer, so autumn may be at the end of its flowering. So it's best to trim it once in this period. In addition to cutting off all the remaining flowers, it is also necessary to properly prune the unsuitable branches, such as those with diseases and pests, dry branches or those affecting the overall ornamental. Pruning is not only helpful for the growth in autumn, but also for the winter.
There may be root rot and other diseases or other insect pests. You should use carbendazim to irrigate the roots every month to prevent them, especially in the early autumn.
