Lavender Plant Seeds for Beginners: A Step-by-Step Guide

Starting with lavender plant seeds can be a bit daunting, but don't worry, I've got you covered.

First, make sure you're using high-quality seeds that are specifically designed for your region and climate.

Lavender seeds are typically small, measuring around 0.2 inches in length, and have a distinctive shape that's often described as oval or egg-shaped.

To begin, prepare a seed starting mix by moistening it with water, but be careful not to overwater, as this can lead to poor germination.

Sow the seeds about 1/8 inch deep and 1 inch apart in a container or tray.

You can start lavender seeds indoors or outdoors, and the timing depends on your location. Count back from the last date of frost according to the seed packet when starting seeds indoors.

The best approach is to start lavender seeds indoors, as it's the preferred method. Planting seeds outdoors is also an option, but it's essential to time it right.

Direct sowing outdoors should happen in the spring, as soon as the ground can be worked. This allows the seeds to get a head start on the growing season.

If your winters are not too cold and wet, you can also plant lavender seeds outside in the fall.

To plant lavender seeds indoors, you'll need a seedling tray with good drainage, potting medium or compost, a mist spray bottle, and plastic wrap or a plastic ziplock bag. Cold stratification is recommended before planting, which involves leaving the seeds in a cold environment for three to six weeks.

For optimal germination, keep the soil temperature around 70°F (21°C). You can use a heating pad or grow lights to achieve this. Seedlings may take up to a month to germinate, so be patient.

To care for your lavender seedlings, continue to mist them lightly each day and keep them warm. Make sure they're getting at least six hours of direct sunlight or light from grow lights per day. Don't add fertilizer, and avoid fertilizing your lavender plants in general.

Here are some key things to keep in mind when transplanting your seedlings to larger pots:

Once your seedlings are about three inches tall and daytime temperatures consistently remain above freezing, you can start hardening them off by placing them outside for increasing amounts of exposure to the outdoor environment. Start by putting them outside in a shady area, then increase the amount of time in the sun each day, but bring them inside at night. After all danger of frost has passed, the seedlings can be planted in the ground in well-drained soil with full sun.

If you're new to growing lavender, you'll be happy to know that there are several types to choose from. English lavender is a popular choice, and it's relatively easy to grow from seed.

One of the most common varieties of English lavender is 'Hidcote', also known as 'Hidcote Blue'. I've found this variety to be quite hardy and well-suited to North American climates.

Another low-growing option is 'Munstead', which is often planted as a hedge. Its compact size makes it a great choice for smaller gardens.

If you're looking for a dwarf lavender, 'Lavender 'Lady'' is a great option. Its flowers have a milder fragrance that's perfect for using in baking and cooking.

For a more dramatic look, consider 'Fathead', a Spanish lavender with beautiful grey-green foliage and long spikes of showy flowers that bees love.

If you want to add some extra visual interest to your garden, you might consider 'Ellagance', a variety that comes in both purple and white. The purple variety has vivid purple-blue flowers, while the 'Snow' variety has spikes of bright white flowers.

To grow healthy lavender plants, it's essential to provide them with the right conditions.

Lavender seedlings need at least six hours of direct sunlight or light from grow lights per day. If you don't have a sunny spot, consider using grow lights.

Keep the soil temperature above 60 degrees Fahrenheit, and ideally between 65-75 degrees Fahrenheit, to promote healthy growth.

Lavender seedlings are susceptible to fungal conditions like damping off, so make sure to provide ample air circulation and allow the surface of the growing medium to dry slightly between waterings.

Water your lavender seedlings lightly, and avoid overwatering, which can lead to root rot.

Once your lavender seedlings have two sets of leaves, start watering them with a balanced plant fertilizer mixed at half-strength.

Transplant lavender seedlings to a larger planter or directly into the garden when they reach 3-5 inches in height.

Before planting outside, seedlings need to be hardened off by gradually exposing them to outdoor conditions.

Lavender plants require 6-8 hours of full sun per day and need to be planted in well-draining locations.

Here are some popular types of lavender you can grow from seed:

Growing lavender seeds requires patience, but with the right conditions, you can successfully germinate and grow these beautiful plants. Sow seeds indoors 6-12 weeks before the traditional outdoor planting time, using a commercially-sterilized soil with a pH between 6.7 and 7.3.

Keep the soil temperature around 21°C (70F) for an optimum germination rate, and lightly water the soil to keep it damp but not soggy. Once the seeds sprout, give them plenty of light, ideally 16-18 hours per day under a growing light.

After the seedlings develop their second set of leaves, begin watering with balanced plant fertilizer mixed at half-strength to promote healthy growth. It's essential to provide ample air circulation and allow the surface of the growing medium to dry slightly between waterings to prevent fungal conditions.

Transplant lavender seedlings to a larger planter or to the garden once they reach 3-5 inches in height, and harden them off before planting outside. This will help them adjust to life outside and reduce the risk of shock.

Growing lavender from seed requires patience and the right conditions. To start, sow seeds indoors 6-12 weeks before the traditional outdoor planting time, using a commercially-sterilized soil specifically formulated for starting seeds.

For an optimum germination rate, keep the soil temperature around 21 degrees Celsius (70F). You can achieve this by placing the seed trays on a heating pad.

Lightly water the soil, keeping it damp but not soggy. Water the seeds in the morning so that the soil can dry during the day. Soil that is too damp and cool will invite fungus to grow.

Once your seedlings develop their second set of leaves, begin watering with balanced plant fertilizer mixed at half-strength. Lavender seedlings are particularly susceptible to fungal conditions, so provide ample air circulation and allow the surface of the growing medium to dry slightly between waterings.

Here's a quick rundown of the ideal growing conditions for lavender seedlings:

Seedlings will need to be hardened off before planting outside. This involves gradually exposing them to outdoor conditions over the course of 7-10 days.

To increase blooms, patience is key - it can take until the 2nd or 3rd year for a lavender plant to reach its full bloom potential.

Make sure your lavender plants are getting a full day of sun, as they need all that sunshine to grow flowers.

Adding too much fertilizer, especially nitrogen, can actually encourage more plant growth, not more flowers.

Harvesting lavender is a rewarding experience, especially when you've grown your own plants from scratch. Gather lavender in June, July, August, and September on sunny days before the flowers open.

Cut the stalks and tie them into small bundles. Hang them to dry upside down in a dark warm place. If you want to collect all the seeds, place a paper bag over the bundles so that the seeds will fall into the bag.

Lavender can self-sow if you let the flowers keep growing.
