You can plant during a heatwave and drought, but the challenge of keeping the root zone damp will be extra difficult. A plant needs moist soil to become established and spread it's roots. Waterwise and drought tolerant plants need time and water to send out their wide and deep network of roots before they can handle heat and lack of moisture. Also, if you are experiencing water restrictions, keeping the water going for a new planting might not be possible. Fall and spring are better for plant establishment. Hopefully, some rainstorms and cooler temperatures will help. Use the hot times of summer to prepare the garden by weeding and mulching.
