About this plant
A small spreading sub-shrub with slender branches and linear dark green leaves that are sticky to the touch. It has small white rounded flowers with pale yellow centres that can completely smother the plant in early summer. A lovely plant for a gravel garden or a hot and sunny spot. Give it space to gently spread.

Spring
Spring - late · Outdoors
Feed young plants with slow release fertiliser
Spread a slow release fertiliser around the base of the plant to the edge of the foliage spread, so that it can feed the roots. It is helpful for this to be applied for several years.
This is a simple way to provide a nutrient boost until the plant becomes well established.
Spring-Autumn · Outdoors
Water in dry periods
Established plants in the ground can cope with 7-10 days of dryness, and shrubs often manage 2 to 3 weeks. Water one section of the garden thoroughly each day rather than a little everywhere. Check plants in pots more often, especially in hot weather.

Trim the plant
Trim the plant to give it a general tidy. This includes removing any lengthy or awkward shoots that make the plant look visually less attractive. Remove any spent flower heads at the same time.
Planting & general
Outdoor planting · Planting
Add root growth stimulant to the planting hole
Mycorrhizal fungi helps roots establish quickly, so they absorb water and nutrients more efficiently. It comes as a powder, granule or gel. Add to the planting hole or container, and to the plant's rootball before planting in the hole. For "bareroot" plants use a gel.
