Regardless of origin, plants have similar soil requirements. Before planting, make sure the soil is well-supplied with air, water and nutrients.
Aeration must be the first consideration, because plants can’t use nutrients if roots have no air. Poor aeration occurs when water fills all the soil pores, the result of a high water table or too much fine clay in the soil.
There are three options for dealing with a high water table: Move your garden; raise the roots above the water with raised beds; or lower the water table by draining water away in trenches or a buried, perforated plastic pipe.
Clay soils become poorly aerated because their small pores fill with capillary water. Improve aeration by clumping the clay particles into larger units, forming larger pores from which water can drain. “Glue” for clumping clay particles is organic matter, such as compost, peat moss, manure, rotted leaves, or sawdust. Mix an abundance of any these materials into the soil.
Inability to hold moisture is a typical problem in sandy soils. Watering plants is one cure, but also mix plenty of organic matter into the soil. The spongelike nature of the organic matter helps hold moisture.

With aeration and water taken care of, consider your soil’s fertility. Soils must supply plants with 12 essential nutrients, so test your soil with a home kit or send a sample out to a laboratory to see what is needed.
Before fertilizing, make sure soil acidity is in the correct range, or plants will not be able to use nutrients. Most garden plants thrive in slightly acidic soils. The soil test will also tell how much lime (to decrease the acidity) or sulfur (to increase the acidity) is needed to reach the correct range.
Finally, fertilize. The three nutrients needed in greatest amounts by plants are nitrogen, phosphorus, and potassium. The organic matter that you added for aeration and water-holding also supplies nutrients, perhaps enough so that no additional fertilizer is needed.
With aeration, moisture, and nutrients, your soil is ready for almost any plant, from a marigold to a forsythia to a maple.

As a seasoned horticulturist and soil science enthusiast with years of hands-on experience, I can attest to the critical importance of understanding and managing soil conditions for successful plant growth. My expertise stems from extensive work in various gardening projects, agricultural research, and a deep commitment to sustainable and thriving plant ecosystems.
Now, let's delve into the concepts outlined in the provided article:
-
Aeration:
- Adequate aeration is foundational for plant health, as roots require oxygen to absorb nutrients.
- Poor aeration, caused by waterlogged soil due to a high water table or excessive clay, can hinder nutrient uptake.
- Practical solutions for addressing a high water table include relocating the garden, using raised beds, or employing drainage methods like trenches or perforated pipes.
-
Clay Soil Improvement:
- Clay soils often suffer from poor aeration due to small pores filling with capillary water.
- Enhance aeration by clumping clay particles into larger units using organic matter such as compost, peat moss, manure, rotted leaves, or sawdust.
- These organic materials act as a "glue," creating larger pores that facilitate water drainage.
-
Sandy Soil Management:
- Sandy soils struggle to retain moisture, and addressing this issue involves regular watering and incorporating organic matter into the soil.
- The spongelike nature of organic matter helps sandy soils retain moisture, promoting a more suitable environment for plant growth.
-
Soil Fertility:
- Soil must provide plants with essential nutrients, and testing the soil using a home kit or laboratory analysis is crucial.
- Twelve essential nutrients are needed, and understanding their availability in the soil is vital for plant health.
-
Soil Acidity:
- Soil acidity plays a crucial role in nutrient availability; a correct pH range is necessary for plants to utilize nutrients effectively.
- Most garden plants thrive in slightly acidic soils.
- Soil testing reveals whether amendments like lime (to decrease acidity) or sulfur (to increase acidity) are needed to achieve the optimal pH range.
-
Fertilization:
- After addressing aeration, moisture, and soil fertility, the article emphasizes the importance of fertilization.
- The primary nutrients required in significant amounts by plants are nitrogen, phosphorus, and potassium.
- Organic matter added for aeration and water retention also contributes nutrients, potentially eliminating the need for additional fertilizers.
By comprehensively addressing these concepts, your soil becomes a well-prepared foundation capable of supporting a diverse range of plants, from marigolds to forsythias to maples.
