Here in the Riverland the weather has been like adelaide, only add about 4 degrees each day and no sea breezes.
My first year pride of Boston has 3 bines that have gone up to about 6 foot then across in various directions another 4-6, the first side branches that came off at 6 foot have headed off towards the north and are growing bigger than the "main" vine they came from, so much for controlling where she goes!
I was unprepared for this much success. I'm a stay at home gardener so she gets watered atleast 4 times a day, and fed every couple of days, there are somewhere between 500-1000 cones forming, quite a shock considering what I was told about first year flowering.
This was until the heat wave though, and some of the thinner newer vine section have browned and wilted, leaves have gone crispy.
I was bragging for weeks how hardy hops are in the sun, after the beetroots, herbs, cucumbers, eggplants, chillies tomatos all wilted one after the other as the days got hotter and the sun got harsher over the last 3 weeks.
So i've run a length of 50% shade cloth across the top of the veggie garden (runs the width of my backyard about 10-15m), and despite 46oC yesterday and 48 a few days before, damage has stopped and recovery has begun.
At first I thought the issue was just water, roots drying out or something, so I set up my mashtun to gravity drip drip drip all day and mos of the night, but the crisping continued so I'm convinced its the effect of the full sun radiating and burning the leaves. Does this fit with your experiences in Adelaide and Melbourne folks?
The tip about infrequent deep watering has been noted, will try to exercise restraint from time to time, though I'm only renting and having a shallow root mass sounds like a good thing if I'm moving again soon.
