Growing lavender in pots is a simple and rewarding project, perfect for anyone, even if you don’t have much space or your garden soil isn’t ideal. This guide will walk you through everything you need to know to successfully grow thriving lavender in pots.
Quick Answer:
Growing lavender in pots is easy! Choose a sunny spot, use well-draining soil, and water carefully. Select a pot with drainage holes and a lavender variety suited for containers. With proper care, you’ll be enjoying fragrant blooms in no time!
Why Grow Lavender in Pots?
Lavender, with its silvery foliage and soothing scent, brings a touch of Provence to any space. But why choose to grow it in pots instead of directly in the ground? There are several excellent reasons:
Limited Space: If you live in an apartment, condo, or have a small yard, pots are the perfect solution for growing lavender.
Poor Soil: Lavender thrives in well-draining, slightly alkaline soil. If your garden soil is heavy clay or acidic, pots allow you to create the ideal growing environment.
Mobility: Potted lavender can be easily moved to follow the sun or be protected from harsh weather.
Control: Growing in pots gives you more control over watering and fertilization.
- Aesthetics: Potted lavender adds a touch of elegance and charm to patios, balconies, and entryways.
Choosing the Right Lavender Variety for Pots
Not all lavender varieties are created equal, especially when it comes to container gardening. Some grow much larger than others, making them less suitable for pots. Here are some excellent choices for growing lavender in containers:
English Lavender (Lavandula angustifolia): This is a classic choice known for its sweet fragrance and compact size. Popular varieties include ‘Munstead’ (compact and early blooming), ‘Hidcote’ (deep purple flowers), and ‘Baby Blue’ (smaller and more compact). These are generally quite hardy, so more forgiving for beginners.
French Lavender (Lavandula dentata): This variety has distinctive toothed leaves and a slightly different scent. It tends to bloom for a longer period.
Spanish Lavender (Lavandula stoechas): This lavender is easily recognized by its distinctive "ears" or bracts at the top of the flower spikes. It blooms prolifically but can be less cold-hardy than English lavender. ‘Otto Quast’ is a good choice.
- Goodwin Creek Grey Lavender: This variety is not technically a true lavender, but it’s a hybrid that is drought tolerant and thrives in containers. It has beautiful silver foliage.
When selecting your lavender, consider:
- Size: Choose a variety that stays relatively compact.
- Hardiness: Select a variety that is suited to your climate.
- Fragrance: Pick a scent you enjoy.
- Appearance: Consider the flower color and foliage.
Selecting the Right Pot for Lavender
Choosing the right pot is crucial for the health of your lavender. Here are some important factors to consider:
Drainage: This is the most important factor. Lavender needs excellent drainage to prevent root rot. Make sure your pot has plenty of drainage holes.
Material: Clay or terracotta pots are ideal because they allow the soil to breathe and dry out more quickly. Plastic pots retain more moisture. If you use a plastic pot, be extra careful not to overwater.
Size: Choose a pot that is at least 12 inches in diameter and 12 inches deep. Lavender needs room for its roots to grow. As the plant matures, you might need to repot it into a larger container.
- Shape: Wider pots are generally better than tall, narrow pots, as they provide more surface area for drainage and root growth.
The Best Soil for Potted Lavender
Lavender needs well-draining, slightly alkaline soil. Regular potting soil is often too heavy and retains too much moisture, which can lead to root rot. Here’s a recipe for a good lavender potting mix:
- 1 part potting soil
- 1 part coarse sand or perlite
- 1 part compost
You can also add a handful of horticultural lime to help raise the pH of the soil.
Make sure to mix the ingredients well before filling your pot. Avoid using soil from your garden, as it may contain pests, diseases, or excessive clay.
Planting Lavender in a Pot: Step-by-Step
Now that you have your lavender variety, pot, and soil, it’s time to plant!
Prepare the Pot: Place a layer of gravel or broken pottery at the bottom of the pot to improve drainage.
Add Soil: Fill the pot about two-thirds full with your prepared potting mix.
Remove Lavender from Nursery Pot: Gently remove the lavender plant from its nursery pot. Loosen the roots slightly if they are root-bound.
Plant Lavender: Place the lavender plant in the center of the pot. Make sure the top of the root ball is level with the soil surface.
Fill with Soil: Fill the remaining space with potting mix, gently firming the soil around the plant.
Water Thoroughly: Water the lavender deeply until water drains out of the drainage holes.
- Add Mulch (Optional): Add a thin layer of gravel or pea stone mulch to the surface of the soil. This helps to improve drainage, retain moisture, and prevent weeds.
Caring for Potted Lavender
Once your lavender is planted, it’s important to provide proper care to ensure it thrives.
Sunlight
Lavender needs at least 6-8 hours of sunlight per day. Place your potted lavender in a sunny location where it will receive plenty of light. If you live in a hot climate, afternoon shade can be beneficial to prevent the plant from getting scorched.
Watering
Watering is crucial for healthy lavender, but overwatering is a common mistake. Lavender prefers to dry out between waterings.
How to Water: Water deeply when the top inch of soil feels dry to the touch. Water at the base of the plant to avoid wetting the foliage, which can encourage fungal diseases.
Frequency: The frequency of watering will depend on the weather, the size of the pot, and the type of soil. In general, you will need to water more often during hot, dry weather.
Signs of Overwatering: Yellowing leaves, wilting, and root rot are signs of overwatering.
- Signs of Underwatering: Dry, brittle leaves and stunted growth are signs of underwatering.
Fertilizing
Lavender is not a heavy feeder and does not require frequent fertilization. Over-fertilizing can actually harm the plant.
When to Fertilize: Fertilize once in the spring with a balanced, slow-release fertilizer.
Type of Fertilizer: Use a fertilizer with a low nitrogen content. Too much nitrogen can promote leafy growth at the expense of flowering.
- How to Fertilize: Follow the instructions on the fertilizer package. Be careful not to over-fertilize.
Pruning
Pruning is essential for maintaining the shape of your lavender plant and encouraging new growth and flowering.
When to Prune: Prune lavender after it has finished flowering, usually in late summer or early fall.
How to Prune: Cut back the stems by about one-third, being careful not to cut into the old wood. Remove any dead or damaged stems.
- Why Prune: Pruning helps to prevent the plant from becoming woody and leggy. It also encourages new growth and flowering in the following year.
Winter Care
Lavender is relatively hardy, but it can be susceptible to cold damage in harsh climates.
Protect from Frost: In areas with freezing temperatures, protect your potted lavender from frost by moving it to a sheltered location, such as a garage or shed. You can also wrap the pot in burlap or bubble wrap to insulate the roots.
Reduce Watering: During the winter months, reduce watering significantly. The plant will need less water when it is not actively growing.
- Monitor for Pests and Diseases: Check your lavender regularly for pests and diseases.
Pests and Diseases
Lavender is generally resistant to pests and diseases, but it can be susceptible to certain problems, especially in humid conditions.
Root Rot: Root rot is a fungal disease that is caused by overwatering. Prevent root rot by using well-draining soil and avoiding overwatering.
Fungal Diseases: Fungal diseases, such as leaf spot, can occur in humid conditions. Improve air circulation by spacing plants properly and pruning regularly.
Aphids: Aphids are small, sap-sucking insects that can infest lavender plants. They can be controlled with insecticidal soap or by hand-picking them off the plants.
- Spider Mites: Spider mites are tiny pests that can cause yellowing and stippling of the leaves. They can be controlled with insecticidal soap or by increasing humidity around the plant.
Harvesting and Using Lavender
Harvesting lavender is a rewarding experience. You can use the flowers to make sachets, potpourri, teas, and other crafts.
When to Harvest: Harvest lavender flowers when about half of the buds have opened.
How to Harvest: Cut the stems with sharp scissors or pruning shears.
Drying Lavender: Tie the stems together in small bundles and hang them upside down in a cool, dry, and well-ventilated place. It usually takes a few weeks for the lavender to dry completely.
- Using Lavender: Once the lavender is dry, you can strip the flowers from the stems and use them in a variety of ways.
Common Problems and Solutions
Even with the best care, you might encounter some problems when growing lavender in pots. Here are some common issues and how to address them:
Yellowing Leaves: This can be caused by overwatering, underwatering, nutrient deficiencies, or poor drainage. Adjust your watering habits, fertilize as needed, and ensure good drainage.
Lack of Flowers: This can be caused by insufficient sunlight, over-fertilizing, or improper pruning. Make sure your lavender gets enough sun, avoid over-fertilizing, and prune after flowering.
Leggy Growth: This is often caused by insufficient sunlight or improper pruning. Move your lavender to a sunnier location and prune regularly.
- Root Rot: This is caused by overwatering and poor drainage. Repot the lavender in fresh, well-draining soil and avoid overwatering.
