Where are you gardening? Rhodys are pretty hardy plants, once they are established. They need acid soil and half day shade, unlike your roses which need full sun. Don’t worry about the droop. They often droop when stressed. Did you apply transplant “shock” when you planted it? If not, you can apply some now.
We tilled an area around a shed in our backyard. It gets some sun during the day but shade as well. I didn’t know about a product named transplant shock? Can I get that at my local gardening center? The soil is definitely acidic since it is somewhat in an area with pine needles (drop offs from the trees about forty feet away). It was droopy in the pot before planting and just hasn’t “picked” up again.
