Plants don’t mind a lot of sunlight, but rather if it is combined with dry air - dry strong wind and at the same time insufficient watering for unprotected roots. The plant can protect itself by dropping leaves, going to sleep prematurely, getting heatstroke, or it can even dry out - die.
Under such conditions, I would try to enclose the planting against the wind all around, protect the roots from drying out and, in case of dry wind, irrigate sufficiently, including around the plants, and at the same time also occasionally water the leaves on the bushes - the entire bushes.
Cultivation in 90L containers on sawdust and ash also proved very useful for me, which I also published. They can be moved and the substrate can be kept sufficiently moist. I have already experimentally planted about 20 plants in this way, and the majority are Auroras.
I came up with the effect with a layer of ash under the roots of the plants by accident. My seedlings were constantly dying in the corner of part of the plot. Then I decided to do it by applying a shovelful of ash under the roots and watching what happens. Since then, the plants have really started to grow and not just grow. They bore a tremendous harvest of large fruits. Since then, I don’t plant any other way. I also applied this knowledge in containers where I plant on sawdust, where there is a 3 cm layer of ash.
The result is that on small annual plants, I have grown shoots more than 1 m long, with a thickness of 1 cm. Something stunning that I didn’t even expect. I published the parentage of the two-year-old shrub, and specifically it was the Vostorg variety. I expect that the two-year-old Auroras in containers will also be covered in fruit, because the branches are full of flower buds. I’ll let you know how the Auroras turn out.
