We call Purslane various plants belonging to very distinct families. This vernacular name therefore designates, among others, this famous Purslane (Portulaca oleracea) with yellow flowers and small fleshy leaves that give it a succulent plant appearance. However, it is not. Widely used in herbal medicine for its many benefits, garden purslane is also widely used in cretan diet. But he is so intrusive that gardeners consider it a weed. Let’s see what are the best solutions to eliminate it.
Where does Market Purslane or Porcelane grow?
This Purslane is a annual plant from the family of Portulacaceae very frequently found in gardens in all of our regions, but even more common in temperate and warm regions of the planet, so obviously in the south of France. This herbaceous plant has an annoying habit of developing without limit on heavily trampled soils and uncultivated areas of the vegetable garden. A hard earth by dint of being trodden in no way discourages this Purslane which, on the contrary, shows itself particularly invasive on bare, hard and dry ground.
Based on this principle, the gardener can largely limit the development of Purslane by keeping uncultivated areas of his land cool, and by asking his children to temporarily suspend ball games there. To do this, rather than regularly watering this uncultivated area, which represents an unnecessary expense and promotes the waste of natural wealth, it is preferable to put a thick mulch mineral in place and ensure that the soil remains sufficiently loose.
What effective solutions to get rid of market purslane?
It is necessary avoid chemicals that can put ecosystems at risk. There are solutions much more respectful of the environment and health to overcome (or almost) the purslane of the garden. The preferred actions are as follows.
Manual removal of Purslane
Nothing better has yet been found to eliminate Purslane without harming the environment. This method, requiring only a little free time and elbow grease, could not be more ecological and economic. However, it can prove to be particularly time-consuming on large grounds where market gardening purslane is very comfortable, and therefore ubiquitous.
Never mind, remove the Purslane stems manually gives excellent results when you show perseverance. If you have a large plot covered with Purslane, it takes several days to several weeks to overcome it.
Weed Purslane before going to seed
The advice applies to all the unwanted grasses and local plants that you do not want to keep for fear of seeing your garden invaded in a short time. We preferably proceed the morning, when it is very early and the dew has not yet evaporated. The earth is then sufficient humid to facilitate the uprooting of Purslane. We use a weeder, ideal tool for uprooting the roots of the plant.
Eradicate purslane with a thermal weed killer
Many gardeners have attempted the thermal weed control to eliminate Market Purslane from their garden because they could no longer be invaded by this plant. Using a thermal weed killer can give good results on condition that you treat very young feet as soon as they appear because they are less tough than adult feet. At the same time, it is essential to strictly respect the principle of this type of weeding, namely to expose a plant to a Thermal shock.
Recall that the intense heat diffused by this device can only be effective if the plants are directly exposed to it for 1 to 2 seconds, never again. The goal is to detonate cells plants, not to burn the external parts because in the latter case, regrowth is assured. Moreover, it suffices to observe nature to see, for example, that after a fire, multiple plants that were thought to be dead reappear. If the plant regeneration is favored by rains, and is possible after such conditions because many seeds buried in the soil survived the fire.
Prevent germination of Purslane seeds with synthetic mulch
Some seeds are able to wait months or even years in the soil to germinate at the best time. For fight against proliferation of garden purslane, must therefore control the germination of its seeds.
To do this, nothing very complicated: we can ask a synthetic mulch cloth of very good quality on the bare areas of the garden. The seeds will then lack light and heat, two essential conditions for them to germinate and for the seedlings to develop. In absolute darkness and a soil not warmed by the sun’s rays, they can no longer grow.
The mulch cloth and geotextile are two separate products that can be used for weed control. The first is used to avoid frequent manual weeding in cultivated areas. As to geotextile, it also prevents weeds from developing but it is preferably placed under a layer of earth or stones.
Can we use market purslane as a ground cover plant?
It is an excellent alternative in the fight against Purslane because it is ultimately a useful plant. We can therefore without any problem keep the Purslane market garden in ditches, along the garden path or down the garage. This ground cover prevents earth flows during heavy rains. It can also find its place at the foot of large species of perennial plants which will benefit from the freshness that Purslane allows the soil to retain in summer.
If you want to use Purslane as a ground cover, however, you have to be careful because there is no question that it covers the entire ground! Full control of its proliferation is essential by hand weeding as regularly as possible, so as to keep only a few feet in strategic places if desired.
