Is it a regal pelargonium? It appears to be planted in sand. Can you plant it into a suitable potting mix? And don't fertilise or attempt to give it anything other than water. It can't make use of any of that stuff until the roots are taking up water properly. It actually looks OK other than a bit of wilting which is not a surprise for plants which have come through the mail. How long has it been planted. It could be droopy for a week and still be OK. Get a better medium, water thoroughly once and then be patient. It doesn't matter that the medium fell off the roots but what do you mean by laying them ON the dirt? The roots should be IN the medium (not 'dirt') and backfilled to the original level.

Hello, thanks for responding. Yes, it's regal. The sand on the top is only a few inches of playground sand to prevent fungal gnats. The rest under that is a mix of peat moss, Arizona native sand and perlite. The wilted leaves have turned yellow and some fell off, but there is a bit of hope in the tips sprouting, even though some look damaged. it's been planted now for a week. The roots were planted in the medium described (sorry, meant to say medium) but the roots were so droopy and everywhere that they weren't fitting well in the hole made, sort of lying there and the plant was wilting already so that it wasn't nice and straight like the others, just lying there and I needed to give it some support.

When you plant a plant like this you don't make a hole and try to fit the plant into it. You part fill the container, place the plant on top of the mix spreading the roots out carefully and then add mix over the roots up to the original planting depth. Firm it in gently around the roots and water in. A 'few inches' of playground sand is far too deep. Did you actually have fungus gnats? They are usually a sign of excess moisture. It may be helpful to remember that pelargoniums are natives of S Africa where they are adapted to droughty conditions. They do not need damp medium.

Thanks for the tips. I think the plant is likely wilting between the shock of travel and the dirt of the root ball coming off. All other plants look fine. Yes, dealing with stupid fungal gnats for over 2 months. Didn't have any until brought an infested plant (mint)--didn't know until later-- and they were crazy for the opened bag of crappy Miracle Grow soil and soon they spread like wild fire. I put a couple inches of sand as suggested on some forums and watering once a week, they are less but it's a lost battle as these things make like 200 babies a day and the eggs remain dormant until the next watering.
