Hi, just got a three rhubarb plants about a month ago and they are on a raised bed with lots of organic material. However despite the crowns continuing to develop ‘buds’ The foliage is full of holes as you can see from the picture. It’s been very dry but I’ve regularly water to avoid drying out. Any ideas what’s wrong? Thanks in advance

The problems appears to be overwatering. Unfortunately, if the soil does not have a chance to dry out between waterings, it will cause root suffocation and rot, as you see here.
You may try these in container, so that you can better control the moisture content of the soil. Make sure that these have a chance to dry out a little between watering.
During the heat, you will need to place in the shade, rather than supply extra water. It may not be possible to grow in your area, if it remains too warm.
