How to Grow a Lavender Plant

Step-by-Step Process (Recommended by Urban Farmer):

  1. Soil & Location: Lavender prefers well-drained, slightly alkaline soil, Lavender can be grown both indoors and outdoors. If you're planting it in pots, make sure the pot has enough holes at the bottom to let water drain out, so the plant doesn't get too much water. An easy hack for home gardeners is to mix crushed eggshells or banana peels into the soil to improve its potassium content, which benefits lavender’s root development.
  2. Planting Method:
    • Outdoor: Plant lavender in a sunny spot where it gets at least 6-8 hours of direct sunlight daily. Space the plants 18-24 inches apart to allow for air circulation and to prevent fungal diseases.
    • Indoor: If you’re growing lavender indoors, place it near a sunny window. Use pots that allow proper drainage. A simple home tip is to add gravel or sand at the bottom of the pot to enhance drainage. This will prevent root rot, which is common in lavender.
  3. Watering: Lavender prefers slightly dry conditions, making it a low-maintenance plant in terms of watering. Water the plant only when the top inch of soil is dry. Overwatering is the most common mistake with lavender, especially in pots, so it's better to be careful. A quick home trick is to stick your finger into the soil; if it feels dry at 1-inch depth, it’s time to water. Use a watermatic stake to water the plant easily.
  4. Temperature & Humidity: Lavender thrives in warm conditions, with ideal temperatures ranging from 15°C to 21°C. While it can tolerate high heat, it struggles in excessive humidity. For home gardeners in humid climates, consider growing lavender indoors during the monsoon season or in well-ventilated areas to avoid mildew and fungal growth.
  5. Fertilizing: Lavender doesn’t need heavy feeding. Use a balanced, slow-release organic fertilizer in the spring to promote healthy growth. Avoid over-fertilizing, as it can reduce the essential oil content and make the plant leggy. For a homemade fertilizer, you can bury banana peels or onion peels in the soil to release nutrients slowly over time.
  6. Propagation: You can easily propagate lavender through cuttings. Simply cut a 4-6 inch stem from a healthy lavender plant, remove the lower leaves, and plant it in moist soil. Keep the cutting in a shaded area until it starts rooting.

Common Problems, Pests, & Diseases

Urban Farmer’s Solutions for a Healthy plant:

  1. Root Rot: This is caused by overwatering or poor drainage. Root rot symptoms include yellowing leaves, wilting, and mushy or decayed roots. To prevent root rot, ensure the soil is well-drained and avoid watering the plant frequently. To prevent or cure, mix 5 gm or half spoon of organic fungicide Tricho Shield per liter of water and drench 50 ml of the solution near the plant's stem. Repeat it 7 days after the first drenching for the best results.

  2. Aphids and Mites: Aphids and mites suck the cell sap from the leaves and make the plant weak. These tiny insects can be controlled by spraying the plant with neem oil 2 ml or 20 drops per liter of water. Neem oil is particularly effective for managing a range of pests while being safe for plants.

  3. Powdery Mildew: Lavender can develop powdery mildew in areas with high humidity. Powdery mildew appears as white or grayish powdery spots on the leaves, stems, and buds of plants. Improve air circulation around the plant by spacing it well and pruning regularly. Spray organic fungicide Tricho Shield 5 gm or half spoon per liter of water. Repeat the spray 7 days after the first spray for the best results.

  4. Yellowing Leaves: If the leaves start turning yellow, it’s often a sign of poor drainage or overwatering. Adjust your watering habits, ensuring that the soil dries out between watering sessions.

Best Practices for Growing Lavender

Urban Farmer’s Expert Tips for Lavender:

  1. Pruning for Health: Pruning is an essential practice for lavender as it encourages bushy growth and prevents the plant from becoming too woody. After the blooming period, trim about a third of the plant’s length. This not only keeps the plant compact but also promotes better flowering next season. Make sure to use clean, sharp pruning shears to avoid damaging the plant.
  2. Sunlight Requirement: Lavender needs plenty of sunlight to thrive. If you’re growing lavender indoors, rotate the pot every few days to ensure the plant receives sunlight evenly. Placing the plant in a location with 6-8 hours of direct sunlight is ideal for both flowering and maintaining its fragrance.
  3. Pest Control: Sticky traps can be used around lavender plants to catch aphids and whiteflies. A DIY hack is to make your own sticky traps using yellow cards and applying a mixture of sugar and water. This can help monitor insect populations without the use of chemicals.
  4. Mulching for Healthier Growth: If you’re growing lavender outdoors, mulch with gravel or coarse sand to reflect sunlight back onto the plant and keep the soil dry. Avoid organic mulches like straw or wood chips as they can retain moisture, leading to root rot.

  1. Fertilizers:
    • Balanced Fertilizer: Add one Flora TAB or Bion (Amino Acid) 2 ml or 20 drops in a liter of water and spray on foliage every 20 days at the time of flower initiation. It helps in boosting flowering in plants.
    • Slow-Release Fertilizer: Insert one Bloom stick fully into the soil, 2-3 inches away from the plant stem. Repeat it after 60 days. A single application of one stick provides your plants with a steady supply of nutrients for up to 2 months.
  2. Pesticides:
    • Neem Oil: Neem oil is a natural pesticide that controls aphids, spider mites, and other common pests. Spray neem oil 2 ml or 20 drops per liter water every 20 days or as needed to prevent infestations. It’s safe for use on lavender and won’t harm beneficial insects like bees.
