How to care for hollyhocks during summer heat in Paris?
As someone who prioritizes sustainability in my landscaping, I'm excited to incorporate hollyhocks into my design. However, summer heat can be quite intense here, and I'm worried about their care during the warmest months. I’ve tried to incorporate xeriscaping principles in my garden, but I'm unsure how to balance that with the water needs of hollyhocks. How frequently should I water them during peak summer? And are there any specific tips for keeping them healthy without over-watering? I'd like to hear from anyone who has successfully managed this in similar climates.
