All new growth on my rose bush is pale green, almost white on some shoots. Why?

Question

I moved into a new home with a rose bush in the garden. Initially there wasn’t this problem but in the past 6-8 weeks the new growth has been pale. I live in Malta (hot & humid summer) and water 2-3 times a week.

Answer 1

Roses need 1 to 2 inches of water per week. You may be overwatering if the soil does not dry out between waterings. A couple deep waterings a week should be more than enough in the absence of rain. Poor drainage also can cause those leaf problems but since it is a new occurence makes me think it could be the watering schedule.
