The Secret Life of Herbs

Think herbs are just another plant in the garden? Think again! Each herb brings its own set of intriguing characteristics and needs.

While they're generally easy to cultivate, herbs thrive under specific conditions. Sunlight, water, nutrients, and the right temperature are their secret ingredients for success.

Did you know most herbs fall into two categories? Annuals like basil and cilantro live fast and die young, completing their life cycle in just one season.

On the other hand, perennials like rosemary and thyme are the marathon runners of the herb world, gracing your garden with flavor for years.

Let's explore how these fragrant plants can transform your garden and cooking!

1. Optimal Lighting

One of the most critical factors in speeding up the growth of slow-growing herbs is providing them with optimal lighting. Here are a few tips to help you achieve this:

Choose the Right Type of Light

You must know the different grow lights that offer various light spectrums, impacting herb growth differently.

High-Intensity Discharge (HID) lights, such as Metal Halide (MH) and High-Pressure Sodium (HPS), are effective choices.

MH lights are ideal for the vegetative stage with their blue spectrum, while HPS lights, emitting a red range, are better for flowering.

Additionally, LED grow lights are gaining popularity due to their customizable spectrum, allowing for specific adjustments to meet your plants' needs.

Provide Enough Light


According to The Pennsylvania State University, most herbs require six hours of direct sunlight daily. Herbs like mint, bay, rosemary, and thyme can tolerate indirect sunlight.

Lemon balm and tarragon even grow well in shallow light conditions. Herbs that don't get enough light will become thin, produce smaller leaves, and have a reduced aroma.

Consider Light Intensity

The size of your growing space dictates the necessary intensity of your grow lights. Too little light can slow growth, while excessive power might cause damage. Choose a light intensity that's appropriate for your setup.

2. Proper Watering

Watering your herbs correctly is essential for their growth and vitality. Here's how to get it right:

Timing of Watering

Water in the morning allows efficient water absorption and reduces evaporation throughout the day.

Use the Right Amount of Water

The key to healthy herbs is balancing moisture. Overwatering and underwatering are both harmful.

Water your herbs when the top inch of the soil feels dry, but the frequency and amount will vary based on the herb type, pot size, and environmental factors.

Use the Right Type of Water

Use room-temperature water left to stand for a few hours, allowing chlorine and fluoride to evaporate.

Consider using filtered or distilled water in areas with hard water to protect your herbs from potential harm.

Use the Right Watering Technique

Employ a gentle approach using a watering can or a hose with a soft spray nozzle.

Focus on watering the soil directly rather than the leaves to prevent fungal diseases and ensure the water reaches the roots without disturbing the ground or damaging the plants.

3. Nutrient-rich soil and Fertilization

The foundation of a thriving herb garden is nutrient-rich soil and proper fertilization. Here's how to ensure your soil is ideally prepared:

Test Your Soil

Begin by testing your soil to identify nutrient deficiencies. You can use a home testing kit or send a sample to a laboratory. You can amend your soil with the necessary nutrients based on the results.

Use Organic Fertilizers

Opt for organic fertilizers like compost, manure, or bone meal to enrich your soil. These natural fertilizers provide a balanced nutrient profile without the harsh chemicals in some synthetic options.

Apply Fertilizers at the Right Time

Apply fertilizers at strategic times for maximum benefit. The start of the growing season in spring is usually the best time.

Use slow-release fertilizers to provide a steady nutrient supply according to the package's instructions.

Mulch Your Soil

Mulch your soil with organic materials such as straw, leaves, or grass clippings. This helps retain moisture, regulate soil temperature, and prevent weeds.

As the mulch decomposes, it further enriches the soil with nutrients.

4. Pruning and Harvesting

Growing your herbs demands attention to detail in pruning, harvesting, and maintenance. Here are some essential practices to keep your herbs thriving and productive.

Prune Regularly

To encourage new growth and prevent woody stems, use clean pruning shears to trim away dead or damaged parts. Make clean cuts just above a leaf node to stimulate fresh growth.

Harvest Often

Frequent harvesting promotes new growth and prevents herbs from becoming too woody.

Use clean scissors to snip off leaves or stems ready for use in your cooking. Always leave enough foliage for the plant to continue growing.

Remove Flowers Promptly

If your herbs begin to flower, promptly remove the flowers. This redirects the plant's energy from seed production to producing flavorful leaves and stems.

Fertilize Regularly

Consistent fertilization is vital for healthy herb growth. Use a balanced fertilizer following package instructions. Options like 10-10-10 or 20-20-20 blends provide essential nutrients.

The Recap

In this article, you learned four tips to speed up the growth of slow-growing herbs. Remember, these tips are just a starting point. It would be best if you tailored them to the specific needs of your herbs.

For example, some herbs like basil and cilantro prefer slightly moist soil, while others like rosemary and thyme prefer drier soil.
