You can dig up the daisy, pot it up and move it to shade and keep it well watered, but frankly, transplanting it somewhere else in the garden when it's this hot is probably gonna do it in. Perhaps save it and reposition it in the fall?

I've done it but the plants took a lot of care with watering.
If you can wait until temps cool you will have an easier job and less stressful plant.

I bought a large! shasta the other day. I kept it watered and in the shade for about 4 days then about two days ago I planted it, submerged it in water first, filled the hole with water, then filled in with dirt and then watered twice that day. Next day one flower was kind of wilted but still looked good. I layed the hose nozzle with soak setting on next to it for about 10 minutes today. Just trying to baby it.

Two options:
Move it to the new location and rig up a shade over it (immediately & temporarily) until it takes root. Keep the soil damp and lightly mulched, but don't get water on the plant itself. Give it a diluted dose (a fix) of Miracle Grow in water. This will 'help' prevent wilt.

Or: Don't move it now. Rig up some kind of shade over it so that it is not in direct sunlight until this heat passes or Fall arrives. Give it a diluted dose of Miracle Grow in water to give it a boost. Move it in the fall.

I am having a similar problem with my fancy Shasta daisy that I just love. The soil where it is growing is pathetic and dries out way too fast, even when we're not having a drought. I hate that bed. I've added all kinds of amendments and still it is always dry. Blah!

Gotta find a better place for it...and my other flowers too.

Good Luck!
This heat is a MAJOR drag!

Thanks for all the useful tips. Annie, your Shasta daisy bed sounds like the bed where my roses are..we have admended that bed and it is always dry and always has such fiberous roots in it. Also the cable line is buried in there so I have to watch digging.
