The choice of soil is important for the life cycle of plants. The soil, made up of peat, compost and draining material, must guarantee the plant the correct exchange of oxygen and carbon dioxide, the supply of nutrients and the drainage of water in order to avoid water stagnation. Here, then, 4 practical tips to choose the right one.
Universal potting soil
Universal potting soil is a type of soil prepared in such a way as to be suitable for different types of plants .
It has a neutral pH, which makes it not too alkaline and not too acidic, and excellent water holding capacity. The universal soil, therefore, it is generally suitable to the plants flower and those aromatic. In addition, it is able to improve the quality of the garden soil and its composition can be enriched by the addition of other products.
The size of the vase
In choosing the soil suitable for your needs, you must take into account the size of the plant pot. The amount of draining material depends on it. A large pot needs large pieces of peat and large pebbles as the need to drain water is greater. A small pot will instead require smaller draining material.
The life cycle of the plant
One factor to consider is the life cycle of your plant. Annual plants, such as violets or geraniums, have a short life cycle and, therefore, the universal soil, much cheaper than the others, is the most suitable. In contrast, long-cycle perennials, such as jasmine or viburnums, need a grainy soil. In fact, thanks to the abundance of pebbles present, it will guarantee the correct drainage of water over time.
Potting soil for every type of plant
There are specific soils for the different types of plants. If you are going to grow citrus fruits then you will have to opt for a light one, with a high percentage of organic substance that will help retain moisture. If you love roses and orchids, however, you will have to use two different types of potting soil. In the first case, the specific one for the planting of roses is advisable, light and composed of vegetable humus with a high water retention capacity. In the case of orchids, choose a soil composed of plant or mineral materials, draining and able to dry quickly to avoid stagnant water.
The acidophilic plants, however, such as gardenias, hydrangeas and azaleas require a fibrous specific soil, rich in organic substances but poor in minerals, able to retain water. The succulents, finally, must be protected from waterlogging through a rich sandy loam and organic material by strong draining capacity.
