Gardeners frequently ignore the effect that soil has on the strength and health of their plants. While not the most exciting part of growing a garden, soil preparation is unquestionably one of the most crucial. Your garden won’t be able to grow to its full potential if your soil isn’t ideal.
“The soil’s quality is reflected in the quality of a garden. Gardens with lovely soil have a liveliness about them that we almost feel, claims author and landscape architect Jan Johnsen.
To acquire that vitality, you must comprehend the chemistry and composition of your soil and establish the best conditions for fruitful plant growth. The majority of the job will be done by your soil by itself if you take care of the fundamentals. Effective soil management is a never-ending effort.
Dig up a scoop of soil and examine its texture prior to planting. Is it heavy, hefty, and does it stick together when wet? Or is it fluid and unrestricted like play sand? It might be in the middle, feeling a little sticky but disintegrating readily, like a just-baked cookie.
Mineral granules, chiefly clay, sand, and silt, make up all soils. They frequently include more of one kind of particle than the others. Although it won’t make them poor growing media, it will have an impact on their density, rate of drainage, and ability to retain nutrients.
There are compromises with each type of soil. Here is a brief summary:
The greatest technique to improve your soil’s structure and give it a more loam-like texture is to add organic matter. Building a raised garden bed and filling it with a combination of well-balanced soil is an additional choice. Alternately, go for the straightforward route by cultivating plants that thrive in your particular soil type, such as selecting drought-tolerant plants for sandy soils. Any soil can support garden growth as long as the plant’s roots are used to the environment.
One of the most crucial elements in evaluating the fertility of your soil is its pH. The nutrients that are accessible to your plants can greatly vary depending on whether your soil is too acidic (pH below 5.5) or too alkaline (pH above 7.5).
Despite the fact that most plants can tolerate a wide range of pH levels, they prefer slightly acidic soils (with a pH of 6 to 7), as those environments enable the simple dissolution of essential components like nitrogen, phosphorus, potassium, calcium, and magnesium. Your plants may receive an excess of some nutrients and a deficiency of others in soils that are overly acidic or alkaline.
How is the pH of the soil measured? Here are your choices:
Take soil samples from various locations across your garden because even within a small backyard, the pH can vary considerably. Lime can be added to your soil to raise the pH if it is low (acidic). Add aluminum sulfate or powdered sulfur if it’s too high. Another option is to select plants, such acid-loving rhododendrons or azaleas, that will flourish at the soil’s natural pH level.
By adding organic matter, every type of soil can be made better.
Here are three typical modifications:
Organic matter enhances nutrient retention and water-holding ability in sandy soils. When applied to clay soils, it breaks apart the minerals that make the soil sticky when wet and hard when dry. Additionally, it provides all soils with an abundant supply of nutrients that gently release for your plants as well as food for beneficial soil organisms. A well-amended soil will eventually supply the majority of the nutrients your plants require, lowering the need for fertilizer.
The majority of soil supplements work best when introduced into the soil in the fall so they are thoroughly absorbed before planting the following spring, claims organic gardener Elizabeth Stell, author of Secrets to Great Soil. You can add soil amendments every season to vegetable gardens, which typically comprise annual or biennial plants. Before planting, perennial gardens should be adjusted to prevent uprooting the plants. Every few years, a lot of perennials need to be dug up for division, which is an excellent opportunity to work in more organic materials.
Don’t only consider soil to be dirt. Imagine it as a small world alive with a wide variety of species that give your garden life. Mother Nature’s recycling team, these critters in your soil ecosystem—earthworms, insects, fungi, and a wide variety of helpful bacteria—convert fallen leaves and plant matter into easily accessible nutrients. They also aid in aeration of the soil and humus formation from organic matter.
“Create suitable conditions to attract microorganisms. You’ll be doing your garden a double favor because these are the exact conditions that encourage optimal plant growth, according to Stell. She advises avoiding the use of pesticides and maintaining an even moisture and air circulation in your soil to promote soil life. Many of these are poisonous to soil life and the insects you’re attempting to eradicate, according to her. Avoid using concentrated fast-acting fertilizers as well, as these chemicals might hurt soil creatures like earthworms. Use slow-release formulations and less concentrated organic fertilizers as an alternative.
By simply spreading organic matter over the soil’s surface and allowing it to organically degrade, mulching enables you to add organic matter to the soil without upsetting plant roots.
Mulch also facilitates:
But mulch also has its drawbacks, particularly if you apply it too heavily and with the incorrect sort of mulching material. It has the potential to leak micronutrients that are bad for plants and alter the chemical makeup of the soil. In humid climes and damp soils, it can also produce circumstances that are perpetually moist and result in fungal diseases of plant roots.
Effective mulches can be made from a range of organic components. However, not all mulches are made equal in terms of how they affect the soil’s biological activity and how rapidly they decompose. See How to Mulch and Avoid Mistakes for further information on the benefits and drawbacks of mulching as well as the best mulches to use in home gardens.
Regarding the advantages of tilling, gardeners have a wide range of views. Many individuals believe that turning and breaking up the soil every year creates a good environment for their plants since it aids in incorporating organic matter and improving drainage. Others claim that tilling is useless and frequently produces the opposite of what is desired.
Tilling has a number of drawbacks. It may impede earthworms’ useful burrowing operations, which are the best source of unpaid work for aerating and removing loose soil. Additionally, it may obstruct the function of crucial soil microbes. Despite these drawbacks, tilling is still a practical choice if you need to incorporate organic matter and nutrients into nutrient-poor sticky clay soil or a freshly dug garden bed. Following that initial deep tilling, you may frequently let nature improve the soil structure on its own.
