  • Neutral to Slightly Alkaline pH: Aim for a soil pH ranging from 6.0 to 7.5, as hardy geraniums typically prefer slightly alkaline conditions and can thrive in neutral soil as well.
  • Soil Amendments: Incorporate organic matter such as compost or well-rotted manure when planting to enhance the soil structure, fertility, and moisture retention capabilities.

By attending to the soil requirements and ensuring favorable soil conditions, gardeners can lay a solid foundation for the successful growth and development of Geranium ‘Tanya Rendall’.

Pruning

Proper pruning practices can help maintain the attractive appearance of Geranium ‘Tanya Rendall’ and promote its overall health and vigor. Consider the following pruning guidelines for this cultivar:
