Before planting your garden, it’s important to take some preparatory steps, especially if you’re growing high-maintenance plants. Even if your soil is in good condition, there are still things you can do to improve it. In the next section, we’ll cover some helpful soil techniques, such as double-digging a garden bed.
Soil is the foundation of a successful garden, and creating the loose, nutrient-rich soil seen in magazines and on TV takes some effort. Soil types vary widely, from dry, sandy soil to heavy clay that becomes slick and sticky when wet. Most soil falls somewhere in between these extremes, but few homeowners start with the ideal “rich garden loam.” Fortunately, soil can be amended with sand or clay, and organic material like leaves, twigs, and manure can improve its texture and structure.
To make the most of the soil in your area, start by having it tested to identify its specific conditions. Then, use the tips that follow to improve your soil and encourage better plant growth.
Soil testing is important before adding any fertilizers or amendments to your garden soil. It helps to determine the type of soil you have, such as light and sandy, moderate and productive, or heavy clay. Getting a soil test from your local Cooperative Extension Service will provide you with information on nutrient levels, pH, and organic content. These factors are important for the overall health of your plants. To get accurate results, follow the instructions precisely and interpret the numbers carefully. If the percentage of organic matter is under 5 percent, your garden needs extra compost. Ratings below 7 are acidic soils, while above 7 is alkaline or basic soil. If necessary, adjust the pH of your soil to make it more moderate and productive. It is always best to choose plants that thrive in the pH of your existing soil. Add only the nutrients your soil test recommends, as too much of any one nutrient can actually harm your plants.
If you have acidic soils, use ground limestone to raise their pH. This natural soil sweetener can neutralize overly acidic soils, but it’s important to add it in the fall to allow enough time for it to dissolve and work its magic. The amount of limestone you use will vary depending on your specific soil conditions, so it’s best to follow the guidelines on the package or get a professional soil test. Adding too much limestone randomly can lead to overdosing the soil. If you have limey or other high pH soils, you can lower their alkalinity and increase fertility by adding cottonseed meal, sulfur, pine bark, compost, or pine needles. These soil amendments gradually acidify the soil while improving its texture. Garden sulfur is particularly effective when added as recommended in a soil test. However, maintaining a new and improved pH is an ongoing project that requires regular soil pH checks and amendment as needed.
To check your soil texture, fill a jar with soil and water and add a little powdered dishwasher detergent. After shaking the jar for a minute, let it sit undisturbed and mark the level of settled particles one minute later (sand), five minutes later (silt), and after an hour or so (clay). Soil with high percentage of sand is well aerated but needs frequent watering and fertilization. Soil with high percentage of clay retains moisture well and needs less watering but requires compost to break up the density. Soil with equal percentages of sand, silt, and clay is generally suitable for gardening. Finally, testing drainage is also important for maintaining healthy soil.
To test the drainage of your soil, dig a hole and fill it with water to see how fast it drains. This simple project is more effective than any soil test and will indicate whether the soil is too dry or too soggy, both of which are not ideal for plant growth. If it hasn’t rained for a week, dig several 1 foot deep and 2 feet wide holes and fill them with water. Keep track of how long it takes for the holes to empty and compare your findings to the following scale: 1-12 minutes indicates sharply drained and likely dry soil, 12-30 minutes indicates ideal drainage, 30 minutes to 4 hours indicates slow but adequate drainage for plants that thrive in moist soil, and more than 4 hours indicates poor drainage that needs improvement. While these soil tests may seem like a lot of work, they are necessary for optimal plant growth.
| Pay attention to the weeds in your garden as they can give you important information about the soil. Weeds are opportunistic and will grow anywhere they can, but different weeds thrive in different kinds of soil. Dandelions, for example, prefer fertile soil. A soil test can determine what kind of soil you have and what nutrients it may be lacking. If there are few weeds, the soil may need work, and if they are stunted and discolored, there may be a nutrient deficiency. Weedy areas are likely to be moister and better for seed germination. |
Once you know your soil’s characteristics, you can amend it to suit the plants you want to grow. There are many ways to improve soil, but the following tips and techniques can help. If your soil test indicates a lack of certain nutrients, organic fertilizers can be used if the imbalance is slight. Inorganic fertilizers are the better choice for quick results or if the nutrient imbalance is great. A combination of both kinds may be a good compromise. Chemical fertilizers usually contain nitrogen, phosphorous, and potassium, and the numbers on the bag indicate the percentage of each nutrient in the mix.

Preparing Soil
It’s important to know the nature of your soil before amending it. Follow the recommendations of the soil testing company if necessary. Organic fertilizers are slowly released into the soil and are inadequate for fast results or major nutrient imbalances. Inorganic fertilizers are better for these situations. Use quick-feeding commercial plant foods first, then follow up with slow-feeding organic fertilizers in subsequent years.
The NPK ratio can be found on every package of organic fertilizer, with lower percentages of each nutrient compared to inorganic fertilizers. Thus, more organic plant food is needed to achieve the same results. In case of a single nutrient deficiency, it is possible to purchase fertilizers separately. If unsure about fixing nutrient deficiency issues, consult with your garden center staff or Cooperative Extension office. Although fertilizers are convenient, there are other methods to enhance soil quality such as adding sources of organic matter like compost, livestock manure, shredded leaves, and more.
your hand. If it forms a ball that crumbles easily, it’s loam. If it forms a ball that is hard to break apart, it’s clay. If it won’t form a ball at all, it’s sandy.
If you’re looking for local compost, check with your city or town hall service department. They may offer compost made from leaves and grass clippings. The compost may be free or at a reasonable price for residents. You can also try contacting the nearest Cooperative Extension Service or landscapers and nurseries, who may compost fall leaves or stable leftovers for their customers. Bulk soil dealers may sell straight compost or premium topsoil blended with compost. Don’t give up if you can’t find local compost right away; someone near you may be composting yard scraps.
If you plan to add bulky organic soil amendments, such as compost, manure, and leaves, by the wheelbarrow-load to improve the soil, keep in mind that the soil level will temporarily rise. As the organic matter decays, the soil level will lower. If soils rich in organic matter drop to expose the top of a newly planted shrub or tree roots, add more soil or organic matter to keep the roots under cover.
When planting around existing trees, shrubs, and perennial flowers, avoid covering the crown with organic material to prevent disease problems. Till or spade a thick layer of compost into lightly moist soil before planting a new garden. If you’re starting with hard, compacted soil, spade the soil first to break it up. Go over the area, removing weed roots and other unwanted vegetation as you go. Then go over the soil with a rototiller. After the first pass, go over it again crosswise until you break the soil into reasonably small pieces.
To maintain the desired texture of your soil, add a 4- to 6-inch-deep layer (more if soil is very poor) of compost to the soil and work it down until it’s 10 to 12 inches deep. The soil will become darker, moister, and spongier. This conversion is a result of the addition of organic matter. As long as the organic matter remains in the soil, the soil is likely to stay loose. However, you’ll need to continue to add organic matter such as compost, mulch, or shredded leaves to maintain the desired texture.
Try spading or no-till systems to preserve the texture and organic content of thriving garden soils. Loosen rich soil before planting by turning the surface shallowly with a shovel and breaking it apart with a smack from the shovel backside. Very loose soil can be made ready for direct seeding by combing it with a hoe or cultivator.
To check your soil texture, squeeze some lightly moist soil in your hand. If it forms a ball that crumbles easily, it’s loam. If it forms a ball that is hard to break apart, it’s clay. If it won’t form a ball at all, it’s sandy.
The crucial thing is to assess your soil’s quality by touch both before and after adding amendments to determine the degree of alteration. Extract a small quantity of slightly damp soil from a few inches beneath the soil’s surface. Compress it into a ball in your hand and observe the outcome when you stretch out your fingers.
Sandy soil has a rough texture and easily crumbles, but can be improved by adding a layer of compost and a small amount of clay. Once enriched, the soil will hold together better. On the other hand, clay soil has a slick texture and forms a tight ball that is difficult to break up. Adding compost and coarse sand can help to lighten the soil and make it easier to work with.
Techniques for Preparing Soil
To create a beautiful rose garden, it is important to have the right soil preparation techniques. Begin by marking the boundaries of the flower bed with pegs and string or a garden hose. Use a spade to cut through the sod along the marked lines and remove it from the entire bed. If the area is rocky, it is important to remove as many stones as possible during digging.
If the soil is sandy or loamy, you can use a rototiller instead of turning it by hand, but clay and rocky soils need to be dug by hand first. For a small planting area, you can dig and break up the soil manually or with a spade. Once the soil is turned, rototilling is possible. If you don’t own a tiller, you can rent one for a day or hire someone to do it by the hour. Spread the necessary fertilizer, soil conditioners, and pH-adjusting chemicals over the area after turning the soil. Ideally, you want to loosen and improve the soil to a depth of more than 6 inches. If the area is too small for a rototiller, you can turn and loosen the soil by hand with a spade. Fertilizers, soil conditioners, and pH-adjusting chemicals will be added at different times of the year for best results.
Now is the perfect time to install a mowing strip around the garden bed, such as patio squares or slate pieces. The mowing strip must be deep and wide enough so that grass roots cannot tunnel underneath or travel across the top to reach the flower bed, and the top of the strip must not extend above the level of the adjacent lawn. Allow the soil to stand unplanted for a week or more if possible. Stir the surface every three to four days to eradicate fast-germinating weeds.
Double-digging is a tradition in many beautiful British gardens, and it’s necessary for high-performance gardens with deep-rooted plants. Double-digging requires manual labor, but you can do a little at a time or hire a professional landscaper if you have health restrictions. Start with vacant soil that is stripped of grass and other vegetation. Remove a strip of soil a spade’s length deep and a spade’s width wide, and put it in a wheelbarrow. Turn the soil below it with a shovel and break it up. Alternatively, you can jab a garden fork into the hard lower soil and rock it around until the soil breaks up. Add organic matter to the lower level if needed.
To create raised beds, one can choose to either add organic matter to the existing soil or start from scratch. If starting from scratch, construct the beds with pressure-treated wood, reinforced concrete, or mortared brick, stone, or blocks. The beds can be any length, but make sure they have a soil depth of at least 6 inches for good root penetration. To fill the beds, pile dug-out earth on a tarp instead of on the grass when digging a hole for planting or excavating a garden pool. This way, excess soil can easily be dragged away and used to build a waterfall or fill the raised bed.
One way to provide optimal soil conditions for a variety of plants is to fill some beds with a rich loam mixture and others with a sandier, well-drained mix. While this may seem expensive at first, the beds can last for years and prove to be a worthwhile investment. Vegetable gardens can simply be mounded up into 6-8 inch high planting rows that are 2-3 feet wide. Permanent or decorative gardens can be raised in attractive frames made from timbers, logs, rocks, or bricks that range from 4 inches to 4 feet high. It’s important to seek professional help for larger building projects that require sturdy structures. If using pressure-treated wood, it’s not recommended to grow herbs or vegetables in the raised beds due to the risk of toxins. Adding mulch to the garden can improve soil health and enhance landscaping appearance. Covering garden beds with mulch can reduce the growth of annual weed seeds and decrease water evaporation. Dark-colored organic mulches made of bark or compost offer a natural appearance while bright gravel can add a pop of color. Straw is a great option for utilitarian gardens like vegetable gardens. Fine-textured mulches like twice-shredded bark, compost, or cocoa hulls work best for thin layers while coarse-textured mulches like straw or bark chunks are better for thicker layers. It’s important to avoid applying fine-textured mulches like grass clippings in thick layers that can suffocate the soil.
The article suggests various ways to improve the quality of soil in your garden. One method involves using newspaper and compost or mulch to kill off unwanted vegetation and add organic matter to the soil. Woody mulch, on the other hand, requires additional nitrogen to prevent the decay process from consuming soil nitrogen that is necessary for plant growth. Mulching new plants with straw or chopped leaves can protect their roots from damage during winter and promote continued root growth. Adding a thick layer of mulch can also improve the soil of existing gardens by releasing minerals and humic acid that fertilize plants and make the soil lighter. Another important reason to mulch is to prevent frost heaving in winter by keeping the soil frozen until spring. Evergreen boughs or straw can also be used to protect evergreen perennials and ground covers from winter burn. Finally, the article notes that snow is the best mulch of all, and can enable you to grow plants that may not survive in areas without snow. With a little effort and the right soil amendments, your garden can thrive.
