All About Lavender
Lavender, also known as Lavandula, is a perennial plant that belongs to the mint family.
Native to the Mediterranean region, lavender is now grown in many parts of the world and is prized for its fragrant flowers, which come in shades of purple, pink, white, and blue.
Lavender is also used for its essential oils, which are known for their calming and relaxing properties.
When to Plant Lavender
The best time to plant lavender is in the spring or fall, when temperatures are mild and the soil is warm.
Lavender prefers well-drained soil with a pH between 6.0 and 8.0, and it thrives in full sun. If planting in the spring, it is important to wait until after the last frost date in your area.
When planting, space the lavender plants at least 12 inches apart to allow for proper airflow.
Lavender Plant Care
Light & Temperature
Lavender is a popular herb that requires full sun to thrive, which means it needs at least 6-8 hours of direct sunlight per day. This is because lavender is a Mediterranean plant that thrives in bright, sunny environments. Therefore, it's essential to choose a planting location that receives plenty of sunlight throughout the day.
In addition to full sun, lavender also prefers cooler temperatures and can become stressed in hot, humid weather. If you're planting lavender in an area with hot summers, consider planting it in a location that receives partial shade during the hottest part of the day. This will help protect the plant from the intense heat and humidity, which can cause the leaves to wilt and the plant to become stressed.
It's also important to note that lavender prefers well-draining soil and doesn't like to be overwatered. Plant lavender in a location with well-draining soil, and water only when the soil feels dry to the touch. Overwatering can lead to root rot and other issues that can harm the plant.
In summary, planting lavender requires a sunny location with well-draining soil, and watering only when the soil is dry to the touch. If planting in an area with hot summers, consider providing partial shade during the hottest part of the day to protect the plant from heat and humidity stress.
Water & Humidity
Lavender is a drought-tolerant plant, which means it's adapted to survive in dry environments with limited water availability. Therefore, it prefers to be watered deeply but infrequently. This means you should water the plant thoroughly, allowing the water to soak deep into the soil, and then wait until the soil is almost dry before watering again.
Overwatering lavender can lead to root rot and other issues, so it's important to allow the soil to dry out between watering. This is especially important in humid climates, where the soil can become waterlogged and the roots can suffocate. In such cases, it's necessary to reduce the frequency of watering to prevent water from accumulating in the soil.
It's important to note that lavender prefers well-draining soil, so be sure to plant it in a location where excess water can drain away easily. Additionally, adding a layer of mulch around the base of the plant can help to retain moisture in the soil and keep the roots cool during hot weather.
In summary, lavender is a drought-tolerant plant that prefers to be watered deeply but infrequently. Overwatering can lead to root rot, so it's important to allow the soil to dry out between watering. In humid climates, it may be necessary to reduce the frequency of watering to prevent waterlogging.

Soil
Lavender plants require well-draining soil to thrive, which means the soil should not be too heavy and retain water. A pH range of 6.0 to 8.0 is ideal for lavender to grow healthy and strong. However, if you're planting lavender in heavy clay soil, you can improve drainage by adding sand or perlite to the soil.
Additionally, lavender benefits from the addition of organic matter, such as compost or aged manure, to the soil. Organic matter can improve the soil structure, making it easier for the roots to grow and absorb nutrients. It can also increase the fertility of the soil, providing the necessary nutrients for the lavender plants to thrive. A layer of compost or aged manure added to the topsoil before planting lavender can significantly benefit the growth and health of the plants.

Fertilizer
Lavender is not a heavy feeder, which means it doesn't require a lot of fertilizer to grow well. However, a light application of a balanced fertilizer, like a 10-10-10, in the early spring can benefit the plants. This type of fertilizer contains equal amounts of nitrogen, phosphorus, and potassium, which are essential nutrients for plant growth.
It's important to avoid over-fertilizing lavender, as this can cause excessive growth and reduced flowering. Over-fertilization can also lead to weak stems, making the plants more susceptible to pests and diseases. It's best to follow the instructions on the fertilizer packaging and apply it sparingly. In general, it's better to under-fertilize than over-fertilize lavender plants.

Repotting
Lavender does not typically require repotting, as it prefers to grow in well-drained soil. However, if you do need to repot, do so in the spring before new growth begins. Use a well-draining potting mix and choose a pot that is only slightly larger than the current container.
Propagation
Lavender plants do not usually require repotting because they prefer to grow in well-draining soil. However, if you notice that your lavender plant is becoming root-bound, or the soil is not draining properly, you may need to repot it. It's best to do this in the spring before new growth begins, so the plant has enough time to establish itself in the new container before the hot summer months.
When choosing a new pot for your lavender plant, it's essential to select one that is only slightly larger than the current container. A pot that is too large can cause the soil to stay moist for too long, which can lead to root rot. A good rule of thumb is to choose a pot that is about 2 inches larger in diameter than the current pot.
It's also important to use a well-draining potting mix when repotting lavender. You can make your own by mixing equal parts of sand, perlite, and peat moss. This will help ensure that excess water can drain away from the roots, preventing them from becoming waterlogged. Finally, be sure to water your newly repotted lavender plant thoroughly and keep it out of direct sunlight for a few days to allow it to adjust to its new environment.
Pruning
Pruning is an essential part of maintaining healthy and vibrant lavender plants. The best time to prune lavender is in the spring, just as new growth begins to emerge. Pruning at this time will help ensure that the plant grows vigorously throughout the growing season.
To prune your lavender plants, start by removing any dead or damaged branches. Next, prune back the previous year's growth to within a few inches of the woody stem. This will help to prevent the plant from becoming too woody and leggy, and encourage it to produce new growth from the base. Be sure to use clean, sharp pruning shears to avoid damaging the plant.
In addition to shaping the plant, pruning also helps to promote healthy growth by increasing air circulation and sunlight penetration to the center of the plant. Proper pruning techniques can help your lavender plants produce more blooms and stay healthy for years to come.

Troubleshooting Lavender Problems
While lavender is generally a hardy plant, it can be susceptible to a few problems. Here are some common issues and how to address them:
Growing Problems
If your lavender plant isn't growing well, it may be due to poor soil, lack of sunlight, or overwatering. Ensure the plant is in well-draining soil, receives full sunlight, and is watered properly.
Pests
Lavender plants can attract aphids, spider mites, and whiteflies. To control these pests, spray the plant with a solution of water and insecticidal soap. Be sure to spray both the top and bottom of the leaves.

Diseases
Lavender is susceptible to root rot if it's grown in soil that's too wet. To prevent root rot, ensure the soil is well-draining and avoid overwatering.
Frequently Asked Questions
Does lavender come back every year?
Lavender is a perennial plant, which means it can come back every year if it is well-cared for and protected during the winter months.
To ensure that your lavender plant comes back each year, it's important to plant it in well-draining soil and choose a location that gets plenty of sunlight. Lavender also prefers dry soil, so be careful not to overwater it. In colder climates, lavender may need extra protection during the winter months, such as covering it with a layer of mulch or bringing it indoors.
