Perennials: tree comes down, shade turns to full sun. Help!, 1 by Badgertalk

I had a problem like this in part of my garden. In 2007 we had a drought and at the same time the electric company cut down a tree next door so the garden when from lots of sun to nuclear furnace. Nearly everything died. I moved a few things into "holding pens" - temporary raised beds that were shaded by fences or buildings.

I found a gazebo someone was giving away on Craig’s List and I made a shade cloth cover. I positioned the gazebo so that it lets in morning sun but shades the area in the afternoon.

You might try something like this.
This is a photo of the gazebo.
