Garden planting
When planting plants, the first and most important problem is the soil, which you may have encountered in the design of the garden.
At present, many new garden soils are directly construction waste, and many gardens have been planted for many years without taking measures to protect and increase soil fertility.
The better the soil fertility, the more conducive to the growth of plants. If the topsoil of plants is ok, but the subsoil has basically lost its fertility and needs to be replaced, it must be buried with organic fertilizer, and the more the better.
When I say organic fertilizer, I mean fully decomposed mixed fertilizer or manure, as well as mushroom compost and multipurpose fertilizer. All these fertilizers can not only increase soil nutrients, but also bond light and sandy soil and loosen heavy soil.
In addition, the pH of the soil must be determined, because different soil qualities will determine what kind of plants it is suitable for. Acid soil is suitable for the growth of Ericaceae plants, such as azaleas and camellia. Alkaline soil is suitable for the growth of clematis, Buddleja and Carnation. Neutral soil can be used to grow all kinds of flowers. To determine the pH of soil, you only need to buy some test materials.
Another big problem is that irrigation water has different pH values in different places, unless you have a bucket (because rain is neutral), which every gardener will encounter. My suggestion is to choose suitable plants according to local conditions and soil properties, so that nature can play its role. It is unwise to let plants struggle to survive in unsuitable soil environment.
