Patchouli: how to plant, cultivate and maintain it

Patchouli is that scent we know so well. It is the aromatic essence of patchouli, rich in sesquiterpenes, which is used by the largest luxury perfumeries. But this woody smell is double-edged: either you love it or you hate it. We reassure you, the plant does not smell that scent. This is a perennial plant that is not at all hardy. That’s why it’s best to grow her in pots in our latitudes. Patchouli can grow up to 1 meter tall and its fragrant leaves resemble those of mint. Come and find out how to grow patchouli in a pot!


1) When to cut your succulents and cacti?

Succulents have the ability to retain water in their tissues, which allows them to cope with the hot weather or lack of watering. The cactus strongly resembles them with the difference that spines and areolas adorn their structure.

It is better to make your cuttings in late spring or early summer, when the weather is hot enough without being in a heatwave.

Gardening with the moon

Following the lunar calendar is, for some, one way to get good results for their garden. It must be said that this is an ancestral method that allows you to follow the seasons. So, effectiveness or not? We explain to you.

The influences of the moon - which revolves around the Earth - have real impacts on our planet. This is especially noticeable with the flow of the tides and even the growth of hair! Could plants and plants, made up of water, also have this action exerted by this satellite? Following the rhythm of the moon for gardening is, in any case, an ancestral technique that is coming back to the fore with organic and ecological plantations. Thus, following the lunar calendar is like referring to the ascending and descending movements of the star. Some believe that the ascending period is suitable for harvesting because this is the time when the sap rises up in the stem. Conversely, during the descending period, the sap goes back down to the roots, so it will be necessary to weed, prune and add compost and fertilizer. There is also a bad time that should not be overlooked: when the moon is at the furthest point from Earth. Better to avoid taking any action during this unfavorable time. While this is not scientifically proven, the fact remains that following the rhythm of the moon will allow you to acquire strict discipline which should, however, do your garden good! All you have to do is download a lunar calendar and roll up your sleeves! Convinced?

Ascending and descending moon VS waxing and waning moon It is not always easy to understand the lunar calendar properly. Some vocabulary bases to know and differentiate:
New moon: ideal for germinating seeds
Descending moon Harvest the root vegetables (in root day). Plant, transplant, prune, multiply (cutting at the beginning of the waning moon, dividing, layering), to be used with the favored part of the plant. Work the soil, bury green manures. Sow.
Rising moon Harvest the aerial parts (in fruit, flower or leaf day depending on the part harvested), take the grafts and graft (in fruit or flower day). Sow.  Waxing moon / waning moon The waxing and waning phases of the moon have little influence on crops in the garden.
