PLANTING and AFTERCARE GUIDE

Best Planting Time

• Spring: Plant Salvia rosmarinus in spring when the soil has warmed. This gives the plant time to establish its roots before active growth begins.
• Autumn: Alternatively, plant in early autumn to allow Salvia rosmarinus to settle before the dormant period, ensuring a strong start the following growing season.

Site Selection

• Sunlight: Salvia thrives in full sun. Choose a location that receives at least 6 hours of direct sunlight daily to encourage healthy growth and abundant flowering.
• Soil: This plant prefers well-drained soil. Incorporate organic matter like compost or grit to improve drainage, as Salvia rosmarinus does not tolerate waterlogged conditions.

Planting Instructions

1. Prepare the Hole: Dig a hole twice the width and the same depth as the root ball. This allows room for the roots to spread easily.
2. Soil Preparation: Enhance the soil with compost or organic matter to provide nutrients and improve texture. This is especially important for Salvia rosmarinus, as it thrives in nutrient-rich yet well-drained soil.
3. Planting: Place the plant in the hole, ensuring the top of the root ball is level with the surrounding soil. Backfill the hole gently, firming the soil to eliminate air pockets.
4. Watering After Planting: Thoroughly water after planting to help the roots settle. Ensure proper drainage to prevent standing water around the roots.

Watering Requirements

• Growing Season: Once established, Salvia rosmarinus is drought-tolerant. Water deeply but infrequently, allowing the soil to dry out between watering sessions.
• Dormant Season: Reduce watering significantly during the dormant season. Salvia prefers minimal moisture during this time.

Feeding

• Spring: Apply a balanced fertiliser in early spring to promote lush foliage and flowering in your Salvia rosmarinus.
• Mid-Summer: A light feeding in mid-summer can encourage continued growth and keep the plant looking vibrant. Avoid over-fertilising, as this can reduce the essential oil content in the leaves.

Pruning

• Regular Maintenance: Prune your Salvia lightly after flowering to maintain its shape and encourage bushy growth.
• Hard Pruning: In early spring, cut back any dead or woody stems to rejuvenate the plant and stimulate new growth. Avoid cutting into older wood, as it may not regrow.

Mulching

• Spring Mulching: Add a layer of organic mulch, such as bark chips or compost, around the base of the plant in spring. This helps retain moisture, suppress weeds, and regulate soil temperature.
• Winter Mulching: In colder months, mulching provides an extra layer of protection for the roots, especially in exposed areas.

Supporting the Plant

• Natural Habit: Salvia rosmarinus generally has a sturdy growth habit and does not require staking. In particularly windy spots, you may consider providing light support to prevent damage.
