About Castilliano Violet, Lavender Seed, Lavender Seed

Castilliano Violet Lavender (Lavandula stoechas) is a stunning variety known for its rich, deep violet-blue flowers and aromatic, fragrant foliage. These seeds produce hardy, bushy plants that thrive in full sun and well-drained soil, making them perfect for garden borders, herb beds, or even containers.

Before Planting

Before planting Lavender, select a full-sun site with light, well-drained soil and good air circulation. Loosen compacted ground and incorporate only modest compost, since overly rich or wet soil can weaken lavender growth and flavor. Prepare a clean, fine seedbed or a freely draining container mix, and avoid fresh manure.

Planting

Start lavender indoors 10–12 weeks before the last spring frost; cold-moist stratification can improve germination for many seed lots. Sow in a free-draining medium around 65–70°F and keep it lightly moist, never saturated. Expect slow, uneven emergence. Provide strong light, pot seedlings up when sturdy, and harden gradually before transplanting after severe frost danger passes.

Watering

Allow the soil around lavender to dry somewhat between deep waterings. Avoid frequent shallow irrigation and wet foliage; established plants generally need supplemental water only during prolonged dry weather.

Fertilizer

Use minimal fertilizer on lavender, guided by visible growth and soil tests. Avoid high-nitrogen products, which encourage excessive foliage, weak stems, and reduced aromatic quality.

Harvesting

Lavender may be cut repeatedly once vigorous growth begins. Use clean shears, harvest before flowers fully open for best leaf quality, and collect seed heads only after they turn dry.

Tips

Keep lavender compact by harvesting or pinching often. Container plants may need occasional repotting, while tender perennials can be moved indoors before frost for continued growth.

Pests & Diseases

Phytophthora and Pythium root rots are lavender’s greatest disease risks; Septoria leaf spot and Botrytis appear in humid growth. Sudden wilt in wet soil seldom improves. Remove affected plants, improve drainage before replacing them, keep mulch off woody crowns, and prune lightly for airflow without cutting into bare old wood.

Lavender may attract aphids, spider mites, caterpillars, slugs, or beetles. Inspect before harvest, use physical removal first, and avoid persistent broad-spectrum products on foliage intended for use.
