When I asked her why this was she explained that in her experience strong sun and wind can be very hard on new transplants, and, despite her careful and plentiful watering, they could not recover from the stress. However, those amaranth plants that she had re-planted during a cooler, cloudier day were looking much healthier.

I tried to find some information online and there wasn’t much about this the best times of day to perform your garden transplants, though there were plenty of resources on how to reduce transplant shock in general.
