What is the Best Soil for Growing Plants in Containers?
So, what is the best soil for growing plants in a container garden? Containers are designed to provide easy access to the roots of the plants you are growing. They are not designed to provide a good, deep, loamy soil that supports roots well. So when choosing a good soil, container gardening is not the best choice for heavy, dense, greeneries like those of trees. Instead, pot gardening is the best choice for these types of plants.
There are three basic kinds of soil: silt, sand, and clay. Clay is usually an even blend of all three. In shallow containers, you probably want to use silt. However, if you have a lot of plantings, it might be better to use either silt or sand in the potting mix. Clay is generally not the best medium for growing plants, as it does not hold moisture well.
If you are growing very large plants, such as tulips or sunflowers, a good potting medium is medium clay. Clay soils hold onto water well, are free of nitrogenous plant roots, and contain a higher level of oxygen than do other soil types. However, if you are growing plants of a medium size, such as sunflowers or herbs, it may be better to use silt instead of clay, especially when they are being grown in containers. It will take longer to root in silt-based mixes, but it will hold onto the water better and will also provide the plants with a higher level of nutrients.
Soil that contains a medium fluffy texture will work well for most plants, although you can add some sand to the mixture if needed. Loam soil has the benefits of being relatively loose and not very compacted. It tends to drain easily and will hold onto water well. Loam soil can be used in all kinds of growing conditions, including the more extreme tropical environments. But the benefits of this soil type are greatly improved by the addition of a medium-appearing fertilizer that contains more nutrients.
Sandy soils are similar to clay, except they have a finer texture and tend to drain more quickly. They work best when they are mixed with sand or silt. These kinds of soils also tend to have higher levels of dissolved solids. Because of this, they are a great choice for container gardens.
A good combination of sand, silt and loam soil will produce the best results if you are trying to grow plants that are a bit larger than your average family. When using these types of soils, it is important to provide your plants with an adequate amount of sun, whether or not they prefer full sunlight or shade. In the best cases, the plants will do very well even in direct sunlight, but if that is not possible, keep the extra light that the plants will need on the shade side.
Loose sand and clay provide excellent drainage, but they also require regular water. This is because both types of earthy mediums are somewhat water absorbent. If you plant plants that love moisture, these two combinations are perfect, but if you are planning to use different kinds of fertilizers, be sure to mix them up regularly. One application of each should be enough.
In any case, it is important to check with local nursery sales or garden centers for the various soils that they carry. The cost of this type of material can vary greatly, so it is necessary to comparison shop carefully. You may find a bargain at the nursery that you cannot find anywhere else, so it pays to stay alert. Your soil will thank you for your diligence when you begin to grow a large number of plants that require similar conditions. For example, if you need clay for your soil, your best bet is probably sand, unless your climate is extremely hot.
