Strawberry saxifrage produces plantlets on runners, with its roots needing a balance of moisture and air in the pot. Keep young plantlets supported while they establish instead of letting their runners pull at the parent.
Recognize the runners
Strawberry saxifrage, Saxifraga stolonifera, produces thin runners carrying young plantlets. These are part of its spreading habit, not roots that must all be cut away. Keep the botanical label because the plant is also sold under misleading begonia or geranium names.
Give the leaves protected light
Choose bright filtered light or a suitable shaded outdoor position. Introduce stronger exposure gradually and protect foliage from scorching heat. Natural pale veins and reddish undersides are features of the leaves, not necessarily symptoms requiring feeding.
Maintain gentle, even moisture
Use an airy medium with drainage and water when the upper layer starts drying. Keep the root ball from becoming repeatedly desiccated, but empty surplus from the outer pot. Dense foliage can conceal damp debris around the crown.
Root plantlets before separation
Set a developed plantlet onto a small pot of suitable medium while it remains attached where practical. Separate it after roots establish, handling the fine runner carefully. Young pieces need protected conditions and consistent moisture rather than strong fertilizer.
