Lavender is a popular perennial plant known for its beautiful purple flowers and soothing fragrance. It’s easy to grow lavender in pots, making it a great choice for those with limited garden space. To ensure that your lavender plants thrive and produce abundant blooms, it’s important to provide them with the right nutrients. In this article, we will discuss what to feed lavender plants in pots to promote healthy growth and vibrant flowers.

Why is Feeding Lavender Plants Important?

Feeding lavender plants in pots is essential as they rely on the nutrients available in the soil to grow and develop. The right balance of nutrients will help your plants establish strong roots, produce more flowers, and improve overall plant health. Inadequate nutrition can lead to stunted growth, weak plants, and poor flower production.

Choosing the Right Fertilizer

When it comes to feeding lavender plants in pots, it’s important to choose the right fertilizer. Look for a well-balanced, slow-release fertilizer specifically formulated for flowering plants. Avoid using high-nitrogen fertilizers, as they promote excessive foliage growth at the expense of flower production. Instead, opt for a fertilizer with a higher phosphorus and potassium content, which are essential for promoting flower development and overall plant health.

Applying Fertilizer

When feeding lavender plants in pots, it’s important to follow the instructions on the fertilizer packaging. Generally, it’s recommended to apply fertilizer in early spring, just as new growth begins. You can also apply a second round of fertilizer in midsummer to encourage continuous blooming. Be sure to water the plants well before and after applying the fertilizer to prevent root burn.

Here are some tips for applying fertilizer to lavender plants in pots:

  • Use a liquid or granular fertilizer, depending on your preference and the product instructions.
  • Measure the recommended amount of fertilizer according to the size of your pot and the specific product instructions.
  • Spread the fertilizer evenly around the base of the plant, avoiding direct contact with the stems or leaves.
  • Gently work the fertilizer into the top layer of soil using a small hand rake or trowel.
  • Water the plants thoroughly after applying the fertilizer to help it dissolve and reach the roots.

Organic Fertilizer Options

If you prefer to use organic fertilizers, there are several options available for feeding lavender plants in pots. Organic fertilizers are derived from natural sources and are free of synthetic chemicals. They provide a slow and steady release of nutrients, promoting long-term plant health.

Some organic fertilizer options for lavender plants in pots include:

  • Compost: Mix well-rotted compost into the potting soil before planting or use it as a top dressing around established plants.
  • Manure: Use composted manure from herbivores, such as cows or horses, to provide a nutrient-rich boost to your lavender plants.
  • Seaweed or kelp extract: These natural fertilizers are rich in micronutrients and growth-promoting hormones. Dilute them according to the product instructions and apply as a liquid fertilizer.

Other Nutritional Needs

In addition to fertilizer, lavender plants in pots also benefit from regular watering and adequate sunlight. Lavender plants prefer well-drained soil, so make sure your pots have drainage holes to prevent waterlogging. Water the plants deeply and allow the soil to dry out slightly between waterings to avoid overwatering, which can lead to root rot.

Lavender plants thrive in full sun, so place your pots in a sunny location where they will receive at least 6-8 hours of direct sunlight per day. Insufficient sunlight can lead to weak plants and reduced flower production.


Feeding lavender plants in pots is important for promoting healthy growth and abundant blooms. Choose a well-balanced, slow-release fertilizer with higher phosphorus and potassium content. Apply the fertilizer according to the product instructions, ensuring even distribution and watering before and after application. Consider using organic fertilizers such as compost, manure, or seaweed extract. Remember to provide adequate water and sunlight for your lavender plants to thrive. By providing the right nutrients, you can enjoy the beauty and fragrance of lavender in your pots for years to come.
