Lavandula Hidcote Blue Seedling Tray

For best results with Lavandula Hidcote Blue, plant one seedling plug per 4- or 6-inch container and three per 10-inch container. Use a well-drained soil with a pH of 5.9-6.2, temperatures of 65-75 daytime and 55-65 nighttime, light intensity at 5,000-8,000 fc, and light feed (125-150 ppm N). Pinch once in 4- and 6-inch containers and twice in 10-inch containers. This plant doesn't require PGRs. Watch for thrips, whiteflies, aphids, and fungus gnats. This plant can develop root rot in overly wet conditions.

Blue-purple flower spikes bloom in summer.

Pinch once in small containers, twice in large containers.

Space containers for adequate airflow and sunlight penetration around the base and foliage of each plant.

This plant doesn't need PGRs.

Scout for aphids, whiteflies, thrips, and fungus gnats as part of your Integrated Pest Management plan. Prevention is the best method of treatment for pests.

Aphids are small, soft-bodied insects that cause damage by sucking sap from plant tissue. They reproduce quickly and are particularly attracted to young growth. Curling and yellowed leaves, stunted growth, and stickiness on leaves are signs of an infestation. These insects also spread diseases and reproduce rapidly. Use biological controls or horticultural oils to discourage and kill aphids.

Whiteflies are small, winged insects that eat plant sap and cause yellowed leaves and stunted growth. Severe infestations can lead to plants dying. Prevent infestations by sanitizing surfaces and tools and removing debris. Introduce natural predators and use sticky traps to control populations. Insecticidal soaps and oils are also effective against this pest.

Thrips are tiny insects that eat plant tissue and can transmit viruses. Watch for silvery-white streaks or black spots on foliage and distorted growth. Use natural predators (like predatory mites), insecticidal soap, neem oil, and sticky traps to control infestations and prevent spread.

Fungus Gnats are small, dark flies that lay eggs in damp soil where larvae feed on plant roots, causing damage and death. Watch for adult gnats flying around the plants and check for larvae in the soil. Prevent infestations by allowing the soil to dry between waterings and controlling humidity in the greenhouse. Fungus Gnats thrive in moist conditions. Catch adult gnats with sticky traps to prevent them from laying eggs. Use beneficial nematodes or apply Bacillus thuringiensis.

This plant isn't prone to disease but root rot can develop in overly wet conditions. Prevent disease by watering at the base of each plant in the morning and allowing the soil to dry out between waterings. Provide good airflow in your greenhouse. We recommend using horizontal airflow fans. Grow your plants in full sun, spacing containers so sunlight can penetrate to the soil level of each plant.

Root Rot occurs in poorly drained or overly wet soil, which becomes the host for several types of fungi. It causes stunted growth, wilting, and root system decay. Prevention is the best treatment, and you will avoid most root rot problems by using clean, well-draining media, appropriate containers, and good watering practices for finishing seedling plugs. Inspect plants for signs of disease regularly. Repot infected plants in well-draining soil, adjust your watering schedule, provide better airflow, and use a fungicide if needed.

Plant one seedling plug per 4- or 6-inch container and three per 10-inch container. Use a well-drained soil and completely bury the ellepot centered or evenly spaced in your container.
