In this article we will talk about immersion irrigation, the most recommended for those plants that grow in pots with little substrate, such as bonsai or epiphytic orchids, and for those that are suffering from lack of water.
What is immersion irrigation?
It is a type of irrigation that It is based on introducing the plant in a container with water until all the soil has been well soaked. Normally, the period of time you need to do this is about 15 minutes, but if it is very dry and has compacted so much that it has become a kind of substrate block, it may be necessary to keep it longer.
When can it be used?
Immersion irrigation is one of the most delicate. Plant roots, with the exception of aquatic and those that live on the banks of rivers, they do not want to have excessive contact with water. If they had it, they would simply die asphyxiated since they are not prepared to absorb a large amount of liquid, and less quickly.
Therefore, Only those that are having a hard time due to lack of water should be watered by immersion, as well as those that are growing in pots with little soil. It is also highly advisable to use this type of irrigation to keep the substrate of the seedbeds slightly humid, because if we watered them with a watering can, as the seeds are so small, they could move.
