Key Takeaways

  • Soil mix for lavender in pots should be 30% coarse sand/gravel and 70% organic compost/potting soil with 1 tbsp garden lime to raise pH for an alkaline soil mix.
  • Lavenders prefer low-medium fertility, well-draining, alkaline, sandy/gravelly soils with open soil structure for optimal growth and blooming.
  • Pot size should ideally be 16 inches across and proportionally deep with a layer of gravel at the bottom for proper drainage, and soil should not be firmed around the lavender when planting to allow for root establishment.
  • Well-draining soil and watering frequency are important factors for lavender growth and blooming, and lavenders prefer a porous soil structure with high sand/gravel content for effective water drainage and oxygen supply.

Soil Mix Recipe

We’ve found that the perfect soil mix for growing lavender in pots is a combination of 30% coarse sand/gravel and 70% organic compost/potting soil, with the addition of 1 tablespoon of garden lime to raise the pH to an alkaline level between 7-8. Using garden lime helps to balance the pH of the soil mix, which is crucial for optimal lavender growth.

Lavenders thrive in alkaline soil, and a pH level between 7-8 replicates the optimal soil conditions of their natural Mediterranean range. Coarse builders sand is essential for maintaining optimal soil structure and preventing root rot. It is superior to fine sand for lavender growing as it provides the necessary balance of nutrients, drainage, and texture.

Organic compost mixed with sand/gravel also provides the necessary balance of nutrients and texture for lavender growth. A porous soil structure with high sand/gravel content is imperative for effective water drainage and oxygen supply. The right soil mix, with proper pH balance, is a crucial factor in lavender growth and blooming.

Pot Size and Planting

Let’s talk about the ideal pot size and planting techniques to ensure our lavender thrives and establishes a strong root system for optimal growth and health.

The optimal pot size for lavender is 16 inches across and proportionally deep, which provides enough space for root establishment and insulation during winter. Here are some tips to keep in mind when planting your lavender in a pot:

  • Layer a few inches of gravel at the bottom of the pot to help keep the drainage holes clear.
  • Do not firm the soil around the lavender when planting to allow for root establishment.
  • Fill the pot with a mix of organic compost and coarse sand/gravel to provide the balance of nutrients, drainage, and texture that lavender needs.
  • Evenly mix the compost and sand throughout the pot to create an open soil structure that allows for effective water drainage and oxygen supply.

By following these planting techniques and using the optimal pot size, you’ll be giving your lavender the best chance to grow strong and healthy, with a well-established root system that can support its growth and blooming.

Remember, the key to growing lavender in pots is to create the ideal soil conditions and environment that mimic the plant’s natural Mediterranean range.

Watering and Maintenance

To keep our lavender healthy, it’s important to understand the right watering and maintenance techniques. Lavenders are drought-tolerant plants and prefer infrequent but deep watering. Overwatering can lead to root rot, which is a common cause of lavender death in pots. To water our lavender correctly, we need to check the soil moisture level before watering. The top inch of soil should feel dry to the touch before we water our plant. We can also lift the pot to check its weight. If the pot feels light, it’s a sign that our lavender needs watering.

When watering our lavender, we should water at the base of the plant to avoid wetting the leaves. Wet leaves can lead to fungal diseases, which can harm our lavender’s health. We should also avoid using hard water or water that contains high levels of chlorine, as it can affect the soil pH and damage our plant’s roots. In addition to water, we should also consider fertilizing our lavender to promote healthy growth and blooming. However, we should be cautious not to over-fertilize, as it can lead to leggy growth and fewer flowers. Lastly, we need to prune our lavender regularly to maintain its shape and promote bushy growth. Pruning in the spring before new growth appears can encourage more blooms. When pruning, we should remove the dead wood and cut back one-third of the plant’s overall size. Pest control is also important in maintaining our lavender’s health. We should inspect our plant regularly for pests like aphids, spider mites, and whiteflies and treat them immediately to prevent damage to our plant.

Watering Fertilizing Pruning
Water infrequently but deeply Fertilize in spring with low-nitrogen fertilizer Prune in spring before new growth appears
Check soil moisture level before watering Avoid over-fertilizing Remove dead wood and cut back one-third of the plant’s overall size
Water at the base of the plant Use caution not to over-fertilize Inspect regularly for pests and treat immediately

Frequently Asked Questions

How often should I fertilize my potted lavender plant?

Fertilizing our potted lavender with organic fertilizer benefits its growth and blooming. Identifying nutrient deficiencies in the plant is crucial. Applying fertilizer every 4-6 weeks during the growing season can help maintain optimal soil conditions.

Can I grow lavender in a plastic pot or does it need a clay pot?

Plastic vs clay pots: which is best for lavender? While both work, clay pots are preferred for their porousness and ability to regulate moisture. Tips for watering lavender in pots include providing well-draining soil and allowing it to dry out slightly between waterings.

What is the best location for my potted lavender plant – full sun or partial shade?

Full sun is best for potted lavender, but ensure the soil is well-draining and low-medium fertility. To prevent root rot, use a soil mix with coarse sand/gravel and avoid overwatering.

Is it necessary to prune lavender plants and if so, how often and when?

We prune our lavender plants annually to promote fullness and prevent woody growth. Timing of pruning depends on your climate and when the plant blooms. Prune after blooming and never cut into old wood.

Can lavender plants survive indoors or do they need to be grown outdoors?

Lavender is like a wild horse, thriving in open spaces. Yet, with proper care, it can adapt to living indoors. Growing lavender in small spaces requires attention to soil mix and adequate light. Outdoor growing is ideal for best results.
