Thank you Jean and Elaine.
I don't yet know how to post photos but will try.
Answers to your questions:
- The building is 25 years old
- I've planted gazania, butterfly bush, African daisy, salvia, Mexican heather, African iris, and a hardy type of small daisy
- The soil is being tested - am waiting for a reply.
The soil seems to me to be the problem because when the plants were thriving in containers they were still in the blazing sun.
What soil additives should I use? Black Cow? Fertilizer? Purchased compost ?
I'm going to put an umbrella for midday relief.
