How to Improve Garden Soil With Amendments: 4 Quick Instruction

If you want to know how to improve garden soil with amendments then you are at the right place. Although garden soil appears to be simple, it is a complex mixture of organic materials, minerals, and other nutrients. 1 It supports the growth of plants by channeling water and air to their roots. There are two types of qualities that make for good garden soil: fertility and texture. 

Fertility is a combination of essential nutrients and a pH level in the soil that allows these nutrients to be absorbed by plants. Texture refers to the size of soil particles, the cohesiveness of the soil, and the ability of the soil to transfer water and air. There are steps you can take to improve the fertility and texture of your soil if it is poor.

When Should Garden Soil Be Amended?

When you’re first establishing a garden bed, it’s best to amend the soil. Soil amendments are typically an ongoing task in an existing garden, even if it’s as simple as digging in some compost prior to each year’s plantings. There is usually no need to touch the soil if your plants are growing well. However, if there is room for improvement, it’s time to learn more about your soil and take action.

How to Improve Garden Soil With Amendments: What You’ll Need

Below are some of the things that you need for improving garden soil: 

Equipment / Tools

  • Garden shovel or tiller
  • Gardening gloves


  • Lime or sulfur (as needed)
  • Fertilizer
  • Organic material like  compost, manure, or peat moss.

How to Improve Garden Soil With Amendments: Quick Instruction

Below are some some quick instruction on how to improve garden soil with amendments:

1. Examine Your Soil

The only sure way to know the quality of your soil is to have it tested. This service is most likely provided for free by your local Cooperative Extension Service. Many nurseries also conduct soil tests. The soil report you receive will provide you with a wealth of information about the texture, pH, and nutritional composition of your soil. It will even recommend which amendments to use and in what amounts to correct any deficiencies.

By observing the health of your plants, you can make an educated guess about the quality of your soil. If they’re doing well, don’t mess with what’s working. However, if your plants are yellowing or otherwise appear sickly, it may be worthwhile to test your soil. When it comes to amending your soil, it’s best not to guess because it’s difficult to determine exactly what it requires. For example, what appears to be a nutritional deficiency requiring fertiliser may actually be a pH issue. This is #1 instruction on how to improve garden soil with amendments.

2. Modify the pH of the soil

Soil pH is important because plants cannot properly absorb nutrients unless the acid/alkaline levels are within their ideal range. If a soil test reveals that your pH is off, you will be advised to add lime to raise it or sulfur to lower it. This should be done in stages in an existing garden to avoid shocking the plants.

It is generally advised not to add more than 5 pounds of lime or sulfur per 100 square feet of existing garden. If you’re starting a new garden, use the entire recommended amount. Rake the lime or sulfur over the garden, then thoroughly dig it in with a shovel or garden tiller. Check the pH of the soil every couple of years, as the sulfur or lime will be depleted and must be replenished. This is #2 instruction on how to improve garden soil with amendments.

3. Use Organic Material to Change the Texture of the Soil

Proper soil texture is required for roots to absorb moisture and air. Dense, clay-type soils can become overly moist, causing roots to drown, whereas sandy soils can drain too quickly, preventing roots from absorbing moisture.

The best way to improve soil texture is to add organic material, such as compost or peat moss. Organic matter that decays helps sandy soil by retaining water that would otherwise drain away. It also improves clay soil by loosening it so that air, water, and roots can all penetrate. Furthermore, it promotes beneficial microbial activity and provides nutritional benefits in all soils. This is #3 instruction on how to improve garden soil with amendments.

Organic materials commonly used to amend garden soil include:

  • Compost: Compost is a great amendment that is free if you compost your garden waste and kitchen scraps.
  • Manure: is frequently available from local farms and stables. Compost it until it becomes dark, crumbly, and odorless. Aside from the odor, fresh manure contains too much ammonia and can burn your plants.
  • Peat moss: Peat moss is inexpensive and effective at loosening soil. It’s also very dusty, so wet it first to make working with it easier.
  • Grass clippings: and other plant debris can be worked directly into a garden bed to decompose slowly. Make certain that whatever you put down is seed-free and has not been treated with pesticides or herbicides.
  • Cover crops: also known as green manure, are grown on unused soil with the intention of tilling them in and allowing them to decompose. The roots keep the soil loose, and the plants keep weeds at bay. Clover and vetch, both legume cover crops, contribute nitrogen to the soil. Cover crops are most commonly used in vegetable gardens.

4. Supplement Nutrients Based on Soil Test

Many garden soils provide excellent nutrition, especially if they are rich in organic matter. However, if a soil test or poor plant health indicates that more nutrients are required, you will have the option of using natural organic products or synthetic fertilizers.

There are some advantages to using synthetic fertilizer. It is usually less expensive than organic fertilizer and acts faster. It does not, however, amend the soil; it simply feeds the plants. Its high salt content may also harm the soil in some cases. Meanwhile, organic fertilizers gradually release their nutrients. You won’t get an immediate fix like you would with synthetic fertilizers. However, you will receive a longer, more consistent feeding.

The nutrients in fertilizers vary. Nitrogen, phosphorus, and potassium are the three primary nutrients found in a complete fertilizer. Plants have different nutritional requirements, but in most cases, a complete fertilizer will be used. A soil test can provide more specific fertilizer type and quantity recommendations. Follow the fertilizer label’s application instructions. Granular fertilizers are incorporated into the soil, whereas water-soluble fertilizers are applied with a sprayer or watering can. This is #4 instruction on how to improve garden soil with amendments.

Tips for Adding Amendments to Garden Soil

The simplest way to amend soil is to add compost or another organic material. A yearly application of compost may eliminate the need for all other types of amendments in some cases. Composts made from plants contain fewer salts than composts made from decomposed animal manure. These composts are better for improving soil texture, though both provide adequate nutrients.

A surface mulch is not a true soil amendment, but it can serve that purpose if dug into the soil after it has decomposed. An annual ritual of digging in old organic mulch before applying a new layer of mulch can result in excellent garden soil.

Why Should You Add Garden Soil Amendments?

We frequently hear that soil is composed of particles such as sand, silt, and clay, but this is only part of the story. Soil is a complex ecosystem that contains minerals, organic materials, microbes, and a plethora of organisms that differ from region to region and, in many cases, yard to yard. Soil not only holds plants in place, but it also provides water and nutrients. Building soil is essential for new gardeners, and experienced gardeners appreciate the dark crumbly compost that comes out of their backyard bins.

Gardeners use soil amendments to improve the growth of their vegetable plots and flower gardens. But what exactly do these materials do for our soil? Here are a few of the numerous advantages of implementing amendments:

  • To boost soil organic matter
  • To help the soil food web.
  • Increasing the soil’s ability to retain moisture.
  • To improve soil texture and structure.
  • to increase soil aeration
  • To encourage healthy plant growth and decrease plant diseases.
