Good afternoon, my reader. Gardeners are still debating which soil is ideal for seedlings. Some people take it easy and buy ready-made potting mix from flower and garden shops. But all experts agree on one thing, that some components should not be in the soil in principle.

Clay
The main disadvantages of clay are that it makes the soil heavier and blocks air access. For young plants, this can end fatally, they do not have enough nutrients and moisture, so the seedlings risk dying. Although clay is rich in nutrients, most of them are not available to plants.
Sand (construction and quarry)
It is not necessary to add sand to the seedling soil. In its composition there are no useful and nutritious substances, there is clay that does not allow air to pass through. All these factors do not contribute to the correct growth of seedlings. If you do decide to add sand to the seedlings, then use clean river sand. It is lightweight and does not contain any clay impurities.
Fresh manure
Fresh manure in the soil gives off gases and heat, which are bad for the root system of plants. The roots of young plants are weak, they do not tolerate excess heat. Insect larvae and weed seeds can also be found in fresh manure. Fresh manure is especially harmful for plants that cannot tolerate acidic soil.
Compost
Among gardeners, there are diametrically opposite points of view: someone believes that compost must be placed without fail, someone is categorically against it. But there are several important factors supporting the second point of view:
- In the process of decay, the remains of leaves and stems are released heat, which has a detrimental effect on the roots.
- The dense structure of the compost does not allow enough air to pass through.
There are also points supporting the first point of view:
- Compost releases nitrogen and is essential for the growth of young plants.
- Compost mixes loosen the soil.
Experienced gardeners recommend using compost in moderation, but only good quality and mature compost should be taken.
Fresh sawdust
Sawdust is often used for seed germination. But they do not contain nutrients, so it cannot fully replace the soil. Sawdust-grown seedlings are generally weaker, have undeveloped roots and grow slowly.
Tea brewing
It is an alternative to peat tablets. It is used after a pick to help plants adapt and strengthen. But there are several drawbacks - in a state of active decomposition, the welding closes off access to nitrogen. To prevent this from happening, dry the infusion before use.
Coffee
It used to be believed that brewing ground coffee can enrich the soil with calcium, phosphorus, nitrogen and other nutrients. But alas, after heat treatment, ground coffee loses its beneficial properties, so it is not necessary to add it to the soil.
Straw
Straw is a versatile material for mulching, shelter from the cold, to increase soil fertility. But you should not use it for growing seedlings. The reasons are similar to using fresh manure - the heat generated during decomposition is bad for the roots.
Deciduous humus
In the fallen leaves there is a lot of silicon and fiber, in the process of decay, nitrogen and phosphorus are formed in it, deciduous humus can be compared with cow dung in terms of usefulness. It must be used wisely, do not take infected and moldy leaves and do not put deciduous humus that has not completely rotted into the seedlings.
