Understanding Soil Basics for Herbs

An ideal soil environment is like the engine of the herb’s growth. Of course, watering, location, feeding, etc. are important, but the soil is also paramount. It is like any ecosystem where the herbs will dwell.

To understand it more, you should know that soil’s texture and quality depend on its composition. Any type of soil has minerals, organic matter, living organisms, gas, and water. The minerals are formed from three sizes – clay, silt, and sand. The percentage of these particles gives a unique texture to the soil.

For example, a sample can have 1% to 5% minerals that can be:

Sand 0.05 – 2.00 mm in diameter ( acidic and drain quickly)

Silt 0.002 – 0.05 mm in diameter ( fertile, well-draining, and has moderate moisture-holding capacity)

Clay < 0.002 mm in diameter ( fertile, hold moisture, less drainage)

This percentage of each mineral and its unique characteristics will decide its holding capacity, drainage, and other factors. Also, organic matter can be 1% to 5%. It is derived from dead plants and animals. High organic matter means the soil is fertile and has a holding capacity.

So, identifying the sand, silt, clay, and organic matter in the soil will help you determine its suitability for herbs. Therefore, you should check the soil to see if it’s well-drained, moist, rich, loose, and has a pH of around 6.5 for maintaining the best soil for herbs.

Types of Soil Suitable for Herb Gardening

Here are top soil suitable for herb gardening:

The best soil suitable for herb gardening is loam soil. It is a mixture of mineral types with excellent drainage and quality. It has perfect mixtures and ratios of sand, silt, and clay (40-40-20%), which means it is fertile, well-drained, and best.

Depending on the mineral elements, it can be clay loam or sandy loam. The sandy loamy is best for herbs as it works best in winter and summer. However, enriching it with some organic matter would be best to increase its quality. Overall, it’s the right soil for your herbs.

Potting Mixes: Tailoring to Container Herbs

You can create or opt for potting mixes to make the best soil for herbs. Especially when growing herbs in pots, they need rich, well-draining, and supporting soils. So, you can create potting mixes with various ingredients like peat moss, vermiculite, and perlite.

Also, these potting mixes are available both online and offline. One classic example of making potting mix is:

  • part coconut coir or peat moss
  • 1 part compost
  • 1 part perlite
  • 1 part topsoil

Also, you need to add fertilizers; this creates a nutritious layer of soil that boosts healthy growth. The potted herbs may dry out fast as they can’t draw ground moisture. So, place them south or west-facing, and water regulate for optimal growth.

Well-Draining Soil for Mediterranean Herbs

A sufficient draining soil is good for all herbs. But Mediterranean herbs like rosemary, thyme, oregano, etc., require exceptionally good drainage. This is because the roots of Mediterranean herbs can dry out in very moist soil.

To ensure good drainage in herbs, you can:

  • Pick ideal locations for plantations that are high and have good drainage.
  • Create a raised soil bed with ideal soil to maintain drainage.
  • You can add gravel, sand, compost, or organic material. They have air pockets that initiate good drainage. Also, you can add perlite, which boosts drainage.
  • Try mulching near the plants.
  • Place lots of coarse materials at the bottom of the potted plants.
  • Grow potted plants at sufficient depth and distance and get large pots.
  • It would be best if you used a potted mix for herbs.

Acidic Soil for Woodland Herbs

Woodland herbs like blueberries, cranberries, sorrel, etc., require slightly acidic soil for growth. The range is 4.5 and 6.0. So, test your soil for this. If this is not the range of the soil, you can add organic matter, which helps maintain the acidic nature of the soil.

Plus, the pine needles, oak leaves, or pine bark mulch are acidic, helping get acidic soil. Also, you can add fertilizer for acid-loving plants. These steps and regularly checking the pH will help a lot.

Rich, Moist Soil for Moisture-Loving Herbs

The right soil for your herbs depends on the individual nature of the plants. Some moisture-loving herbs, like mint and chervil, prefer moist soil. But remember, moist soils don’t mean waterlogging.

Some of the tricks to retain moisture:

  • Pick a location that is low-lying and has more moisture.
  • Create a top soil with compost, coconut coir, manure, etc., to improve moisture hold.
  • Try mulching. It helps to retain moisture by avoiding evaporation.
  • Always check the composition of the soil and fix it accordingly.
  • Also, avoid excess sun, which can lead to soil drying.
  • Ensure adequate watering. Too little or too much is not suitable.

Alkaline Soil for Lavender and Other Herbs

Herbs like lavender and sage require alkaline soil. So, test the soil pH first before choosing the locations. Also, you can add farming lime to raise the pH. You can gradually add oyster shells, crushed limestone, or wood ash to increase the alkaline nature. Also, the water, fertilizer, and mulch must not be acidic. This will ensure that the soil remains alkaline.

Therefore, you can make or get various herb-loving composts for the best potting mix for herbs or ground.

Mulching: Guarding Against Weeds and Moisture Loss

Mulching is adding layers of organic matter around the plants. They are excellent for herbs as they create barriers between herbs and environmental factors like sun and wind. This reduces evaporation and retains moisture.

Also, this is an ideal technique for weed suppression. They block the weed seeds from getting sunlight, which prevents their growth. Hence, there is no competition, and herbs are grown in their territory. It also helps in decreasing soil erosion, improves temperature, enhances soil structure, and looks great. For example, you can try straw, wood chips, leaves, etc., for creating soil suitable for herb gardening.
