Trialling Yates Waterwise Drought Shield Spray
I finally have one...yes one...very healthy, bushy green and flowering hydrangea. It is a big achievement for me as every hydrangea I have ever grown has never survived the harsh summers in my Adelaide suburban garden.
Hydrangeas is my part of Adelaide need to potted and never directly planted straight into the garden, so that they can be moved on extreme weather days. The Adelaide Hills provides a completely different environment altogether, and can be easily planted out permanently in the garden.
I normally move delicate pot plants such as hydrangeas inside on very hot days, but there are times when I under estimate the suns intensity on slightly less hot days. And that's when plant sun burn can strike!
So this month I am trialling a product from Yates called Waterwise Drought Shield ($9.95 at Bunnings) to help me through this summer.
Drought Shield also helps to protect against light frosts. Yates recommends that plants be sprayed in early autumn for best protection against frost, and reapplied every 30 days until the risk of frost has passed.
Yates Waterwise Drought Shield claims to protect plants from heat, water loss, drying winds, frost and transplant shock.
Yates does warning that some plants such as bromeliads and ferns may be sensitive to the spray, so always do a test spot on a leaf first and inspect the next day to see if it is suitable for your plants.
I shall be keeping a keen eye on my plants this season to see how good Drought Shield performs.
UPDATE February 2014
Two and a half months later, did the Yates Waterwise Drought Shield work?
As you know I was trying this product out on two hydrangea plants at different ages.
The older one definitely responded well and coped through the hotter days although not unscathed. There were some leaves with burns, but it is now starting to bloom again and that is in a strong heat wave. I have moved it in doors on the days that are above 35ºC. I still take my precautions. But the bounce-back rate on those hotter days have really improved dramatically.
The younger hydrangea unfortunately did not like the Drought Shield and died. But the packaging instructions do warn that not all plants will tolerate the spray, the younger plants in particular.
Here's my survivor. She is ready to show her next blooms!
