Growing lavender in Idaho can be a rewarding venture, both for personal enjoyment and potential profit. The beautiful purple flowers, fragrant aroma, and versatility of lavender make it a sought-after plant for gardens, culinary uses, aromatherapy, and even crafting. This guide will provide you with all the necessary steps to successfully cultivate lavender in Idaho’s unique climate.
Before diving into the growing process, it’s essential to understand what lavender is and its various species. The most commonly grown types are:
In Idaho, English lavender is often the preferred choice due to its ability to thrive in colder climates.
Idaho’s climate presents both challenges and advantages for growing lavender. The state generally enjoys warm summers and cold winters, which can be favorable for lavender. However, certain areas may experience higher humidity or excessive rainfall that could affect the plant’s growth.
Sunlight: Lavender requires full sun exposure for at least 6 to 8 hours a day. Choose areas in your garden that receive ample sunlight.
Soil: Well-draining soil is crucial. Lavender prefers sandy or gravelly soils with a pH of 6.5 to 7.5. Avoid heavy clay soils that retain moisture as this can lead to root rot.
Watering: Once established, lavender is drought-tolerant but requires regular watering during its initial growth phase. Ensure the soil dries out between waterings.
Temperature: Lavender thrives in temperatures ranging from 70°F to 85°F during the day and cooler nights around 60°F to 70°F.
Choose a location that offers full sun and has good air circulation. Avoid low-lying areas where cold air can settle in winter, leading to frost damage.
Testing Soil: Conduct a soil test to determine its pH level and nutrient content.
Amending Soil: If your soil is too acidic, you can add lime to raise the pH. For heavy clay soils, mix in sand or gravel to improve drainage.
Tilling: Till the soil to a depth of about 12 inches to ensure aeration and mix in any amendments you’ve added.
Creating raised beds can greatly improve drainage and make it easier to control soil conditions. They should be at least 12 inches high and filled with a mixture of native soil, sand, and compost.
While starting lavender from seeds is possible, it requires patience as seeds can take several weeks or even months to germinate. Most gardeners prefer using transplants or seedlings for faster results.
Purchase healthy seedlings from local nurseries or reputable online retailers specializing in lavender plants suited for Idaho’s climate.
Spacing: Space plants about 18 to 24 inches apart to allow for airflow and prevent diseases.
Depth: Dig holes that are slightly larger than the root ball of your transplants and plant them at the same depth they were growing in their pots.
Watering After Planting: Water them deeply right after planting but avoid waterlogging the roots.
During the first year, water your lavender every two weeks if there hasn’t been adequate rainfall. Once established, reduce watering; typically, once every three weeks is sufficient.
Lavender doesn’t require heavy feeding; too much nitrogen can lead to less fragrant blooms and weaker plants. Use a low-stakes fertilizer or organic compost once in early spring as needed.
Prune your lavender plants annually after flowering ends but before new growth begins in late summer or early fall. This encourages bushier growth and improves airflow around the plants.
Lavender is relatively pest resistant but occasionally suffers from aphids or whiteflies. Handpick pests when possible or use insecticidal soap if infestations occur. Additionally, ensure good air circulation around plants to prevent fungal diseases.
Harvest lavender flowers when they are fully open but before they start to fade; typically from mid-summer onwards (July-August). Early morning is the best time for harvesting as oils are most concentrated at this time.
Use sharp garden shears to cut long stems above the leaves while leaving some foliage intact for continued growth.
