Sandwich biscuit with succulent soil

The "sandwich biscuit method" with succulent matrix means that the whole basin soil is divided into three layers, and each layer plays a different role. The core idea is to ensure that the permeability and drainage of the matrix is as strong as possible, to prevent rotting roots, after all, to save the life of meat, "keep Castle Peak is not afraid of firewood."

The three layers are the surface layer (pavement layer), the middle layer (nutrient layer) and the bottom layer (drainage layer).

20% of the surface layer is pavement. This layer of red jade, river sand, sea sand (must be thoroughly washed and removed salt), cinder, the proportion can be matched at will according to personal preferences, as paving stone, as long as to ensure air permeability and certain water retention.

The function of paving stone:

First, decoration and beauty.

The second is to ensure the air permeability of plant roots and prevent rotting roots.

Third, the paving stone can drain and dry quickly to ensure that the branches and leaves of the plant do not come into contact with wet soil (as pictured below) and remain dry all the time.

Fourth, the role of fixing and supporting the plant, sometimes the plant grows crooked because of the positive relationship, therefore, through the addition of stone fixed way, to help the plant properly righted.

In addition, it is worth noting that perlite, pumice and iridescent stone should not be used as paving stones, because the density of these two substrates is very small and is better than water. So when watering, it is easy to let them surface alone (as pictured below) and flow out of the basin, affecting beauty and causing waste.

60% of the middle layer is the nutrient layer. It is also the best "cream layer" of "cookies". The main function of this layer is to provide nutrients for plants and maintain roots while ensuring water retention, drainage and air permeability. The principle is to match nutritious materials and breathable granular materials in an one-to-one way. Such as rotten leaf soil, granular peat, peat, plant ash, etc. all belong to nutritional materials; red jade soil, gold plant stone, cinder and river sand belong to breathable granular materials. (PS: although it is granular, the king of flowers should use it as a nutritional material.)

To give some examples:

The collocation of "Gao Fu Shuai" is as follows: 25% red jade soil, 25% 25%WITH rotten leaf soil, 15% granular peat and 10% coconut bran.

The collocation of "ordinary house": 15% red jade soil, 20% cinder, 25% perlite 15%WITH rotten leaf soil, 15% granular peat, 10% coconut bran.

The collocation of "loser": cinder 30%, river sand 20%WITH rotten leaf soil 25%, granular peat 15%, coconut bran 10%.

The above example is to make a reference, as long as a good grasp of nutritional materials and breathable granular materials to one-to-one. You can DIY according to your preferences and economic level.

The following picture shows a middle soil of the King of Flowers, with a proportion of

Red jade soil: rainbow stone: perlite: coconut bran = 2Rd. 2Rd. 2Rd. 2Rd 4. In addition, shell powder is added to supplement trace elements.

The bottom 20% drainage layer. This layer is also red jade, river sand, cinder at will, to ensure air permeability and certain water retention is good OK. In addition, perlite and pumice can be used in this layer, because they will not float to the surface because of the density.

Finally, it is worth noting that when configuring succulent soil, you can also add a little bone powder, shell powder (providing calcium and other trace elements), carbendazim (sterilization), dicyclovir (insecticidal), rooting powder (to help rooting).

The following picture shows the drainage layer of river sand and red jade soil matched by the king of flowers.

The pavement layer is made of sea sand with red jade, and the nutrient layer is red jade soil: rainbow stone: perlite: coconut bran = 2purl 2purl 4, drainage layer river sand with red jade.
