Ideal Conditions and Planting Advice

Getting the conditions right will help Lithodora thrive and give you a long season of stunning blooms.

Location & Soil:

• Prefers full sun for best flowering but can tolerate light shade.

• Requires well-drained, acidic to neutral soil. Avoid heavy clay or waterlogged sites.

• Ideal for alpine gardens, gravel beds, raised borders or the front of a sunny border.

Planting Tips:

• Plant in spring or early autumn while the soil is warm.

• Space plants around 30–40 cm apart to allow room for spreading.

• Add horticultural grit or sand to the planting hole if soil is heavy.

• A mulch of fine bark or leaf mould can help retain moisture and suppress weeds but keep it clear of the plant crown.

Top Tips:

• Lithodora does not like being moved once established; choose the planting site carefully.

• Protect from excessive winter wet by planting on a slight slope or raised area.

Ongoing Care and Seasonal Maintenance

To keep your Lithodora 'Heavenly Blue' healthy and looking its best, regular care is important, especially during its growing and flowering period.

Watering:

• Keep soil evenly moist, especially during dry spells in spring and summer.

• Avoid overwatering or waterlogged conditions, particularly in winter.

Feeding:

• Apply a light feed with a balanced, low-nitrogen fertiliser in spring.

• Avoid overfeeding, which can reduce flowering.

Pruning & Tidying:

• Lightly trim back after flowering to maintain shape and encourage bushiness.

• Remove any dead or damaged stems in early spring.

• Do not cut back hard into old wood.

Winter Care:

• Hardy in most areas but may need protection from harsh frosts, especially in exposed or wet sites.

• In colder regions, consider covering with fleece or growing in containers that can be moved.

Container Growing:

• Use ericaceous compost with added grit for drainage.

• Ensure containers have plenty of drainage holes.

• Keep pots raised off the ground in winter to avoid waterlogging.
