Heat Stress

Post by Pup »

The next few days Victoria is going to get Temps that I and a few others here Experience on a regular basis.
So I thought a few tips might help. If you put old carpet or shade cloth mats over your pots. News Paper watered and waited down helps.
A few buckets of water or bigger receptacles around your Bonsai area to create Humidity.
I have shade cloth over my trees for Summer.
I take it down over winter. I have for the last 15 years since I moved to the southern suburbs of Perth.
:) I hope this helps some of you get through this period with out too much stress on you or your trees. Good luck Pup

Thanks Pup, yep, my babies are going to need all the help they can get. I have about 30 or so, so not a lot compared to others. So I tend to put them all on the ground in shade over days like these. A few days in shade, especially at 40 is not a question for me, even the sun lovers sitting in their pots on these days simply cook.

I'm lucky, I have a few trees that shade some of them nicely, very convenient for me. But, not enough for all of them, so I take some down off their stands and stick them around the house too, just in dark corners for the few days.

It's a bit of work taking them down again and gain, however, i'd rather they lived than died.

When I water I let the watering can drench them and the ground around them to try to help keep it humid, so the grass and the dirt on the ground helps moderate the temp a little.

Poor things, we're getting about 4 days or more of 40. not good. I know other places such as Perth and especially Adelaide get this more often that us...

Wise advice! I heard that the temp in Melbourne is in the 40's today! Wouldnt like to be on centre court for 2 or 3 hours in that! Aparently the temp on centre court is about 8 degrees hotter! Stay cool all you people down there.

Great tips Pup.

On Saturday the temperature at my office (Rosehill NSW) reached 48 degrees!!! To help my plants cope I cut lots of leafy bamboo canes from some clumps I have and lightly covered my bonsai. 100% success with no burnt leaves at all. It's good to be able to make do with what you have around.

Today it is cool and drizzling - just what I and my garden/bonsai need!

Regards,
Steven

Guys remember water and mist if you have too, but at the same time do it carefully so little is wasted.

I use a yates product called stress guard. Helps a lot up here as it reduces water loss through the leaves.

Remember maples will burn even out of the sun in this heat, but if they have a humid surround the burning wont be as bad. I have my shade house misted twice a day and the humidity sits at about 50% and I have had no burning since.

After coming home from work today, about all my plants were looking very bad... about the only ones that weren't were the pines... however, even some of my toughest were wilting badly... we got 42 or 43 today, 43 tomorrow and similar to ADL, a long hot week still to come.

I'm worried, even in the shade, there is no hiding from this heat. A few more days like this, i'm predicting a few fatalities,i think it will be inevitable... :cry:

I'd be stacking them in the house as much as possible. On Sydney's 45 degree day two years ago I was home, watered fully four times, get 3 pm shade on the major benches and still had some damage and lost a couple. And that was just one day! My fingers are crossed for all you in those heat areas. Our $2 shops are flogging long, narrow, black trays for $2 and they make great water trays. If you're working it could be a possibility to pay for those people who tend pets and plants at home to come around a couple of times during the day to water. Other suggestions above are very good.

My thoughts are with you.
