Best Fertilizer for Lavender: Top Picks for Healthy Plants

Lavender is a beautiful and fragrant plant that requires proper care and attention to thrive. If you’re looking to enhance the growth and health of your lavender plants, choosing the right fertilizer is essential.

With so many options available, it can be overwhelming to determine which fertilizers are best suited for your lavender. In this article, we’ll explore the top picks for the best fertilizer for lavender and provide insights on how to apply them effectively.

Whether you’re a seasoned gardener or are new to the game, this guide is designed to help you choose the perfect fertilizer for your lavender plants so that they can grow strong and healthy.

Understanding Lavender’s Nutritional Needs

Lavender plants have specific nutritional needs to thrive and produce the fragrant flowers they are known for. Understanding these needs is essential to selecting the right fertilizer for your lavender plants.

Lavender plants require soil that is well-drained and not too fertile. Over-fertilization can cause excessive growth and lead to weaker stems and fewer blooms. However, a lack of proper nutrients can result in stunted growth and poor flower production.

The primary macronutrients that lavender plants need are nitrogen, phosphorus, and potassium (NPK). Nitrogen is essential for leaf and stem growth, while phosphorus supports root development and flower production. Potassium strengthens stems and helps the plant withstand environmental stressors such as drought and cold weather.

In addition to these macronutrients, lavender plants also require micronutrients such as iron, magnesium, and zinc. These nutrients are necessary for healthy growth and development and are typically found in high-quality fertilizers specifically formulated for lavender plants.

It’s essential to choose a fertilizer that provides balanced nutrition without overloading the soil with unnecessary nutrients. Organic options, such as compost or well-rotted manure, can also provide the necessary nutrients while improving soil quality.

Factors to Consider When Choosing Lavender Fertilizer

Choosing the right fertilizer for your lavender plants can be overwhelming, considering the various products available in the market. However, there are essential factors to consider to ensure that you select the best nourishing lavender fertilizer that suits your plant’s needs:

  1. Lavender Nutritional Requirements: Lavender plants require a well-balanced fertilizer that contains nitrogen, phosphorus, and potassium in the ratio of 1:2:1. Nitrogen promotes green foliage growth, phosphorus aids in flower and fruit development, while potassium increases disease resistance and overall plant health.
  2. Fertilizer Formulation: Consider the fertilizer formulation type before purchase. Synthetic fertilizers provide a quick boost of nutrients to the plant, while organic fertilizers release nutrients slowly, resulting in more robust root growth and healthier plants.
  3. Fertilizer Type: There are several types of fertilizers, such as liquid fertilizers, granular fertilizers, and time-release fertilizers. Choose the fertilizer type that suits your gardening needs, depending on the plant’s growth stage and the fertilization frequency.
  4. Soil Type: The soil type significantly influences the choice of lavender fertilizer. For instance, if the soil is acidic, consider using a fertilizer that contains calcium, magnesium, and sulfur to balance the soil pH level.
  5. Fertilizer Application Method: Consider the fertilizer application method, depending on the fertilizer type and gardening preference. Liquid fertilizers require regular application, while granular and time-release fertilizers have recommended application guidelines.

By considering these essential factors, you can choose the best organic lavender fertilizer that provides your plant with the essential nutrients for healthy growth.

How to Apply Lavender Fertilizer

Once you have chosen the right lavender fertilizer, it’s time to apply it to your plants. Here are some important tips to keep in mind:

  • Apply the fertilizer in early spring before the plant starts actively growing, and again in late summer after the plant has finished blooming.
  • Water your lavender plant thoroughly before applying the fertilizer to avoid burning the roots.
  • Spread the fertilizer evenly around the base of the plant, being careful not to let it touch the leaves or stems.
  • Use a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium.

For an extra boost of growth, you can also use a liquid fertilizer designed specifically for lavender. Simply dilute the fertilizer with water according to the package instructions and apply it to your plants every two to three weeks during the growing season.

How to Apply Liquid Lavender Fertilizer

To apply liquid lavender fertilizer:

  1. Fill a watering can with the diluted fertilizer.
  2. Water the soil around the lavender plant until it is saturated.
  3. Increase the amount of fertilizer or frequency of application if you notice slow growth or yellowing leaves.

Remember to always follow the instructions provided by the manufacturer when applying fertilizers. Over-fertilizing can damage your plants, so it’s important to use the right amount and apply it correctly.

Additional Tips for Fertilizing Lavender

While choosing the right fertilizer is crucial for the health and growth of your lavender plants, there are a few additional tips you can follow to ensure they thrive:

  • Don’t over-fertilize: Too much of anything is harmful and the same applies to fertilizers. Over-fertilizing can result in weak and leggy growth, and may even lead to plant death. Follow the instructions on the packaging and refrain from adding more than what is recommended.
  • Apply fertilizer at the right time: Lavender plants should be fertilized during the growing season, which is typically from spring to fall. Avoid fertilizing during winter as this is a dormant period for the plant.
  • Water after fertilizing: To prevent burning the roots, water your plants thoroughly after applying fertilizer. This will also help the nutrients to penetrate deep into the soil.
  • Use a growth booster: If you want to give your lavender plants an extra boost, consider using a growth booster in addition to the regular fertilizer. This will promote healthy growth and help your plants produce more blooms.
  • Monitor your plants: Keep an eye on your lavender plants and observe how they respond to the fertilizer. If you notice any adverse effects, such as yellowing leaves or stunted growth, stop fertilizing immediately and adjust your fertilizer regimen.

By following these tips, you can ensure that your lavender plants receive the right amount of nutrients and grow into healthy, thriving plants.

Caring for Lavender Plants Beyond Fertilization

While fertilization is an important part of caring for lavender plants, there are additional steps you can take to ensure their health and longevity.


Lavender plants require well-draining soil and prefer to be watered deeply but infrequently. Watering once a week during the growing season should suffice, but be sure to check the soil moisture level before watering. Overwatering can lead to root rot and other issues.


Pruning lavender plants can help promote bushier growth and increase the overall lifespan of the plant. Trim back any dead or woody stems, and pinch back new growth when the plant reaches about six inches tall to encourage branching.

Pest Control

Lavender plants are generally pest-resistant, but certain insects like aphids or spider mites can sometimes be a problem. Use natural insecticides like neem oil or garlic spray to control infestations and avoid using harsh chemicals that can harm the plant.

Soil Maintenance

In addition to fertilization, soil maintenance is also important for keeping lavender plants healthy. Be sure to add compost or other organic matter to the soil to improve its structure and fertility, and consider using a mulch to help retain moisture and regulate soil temperature.

By following these tips, you can help ensure the health and vitality of your lavender plants for years to come.
