I rescued the final Mother's Day Hydrangea at my local Walmart. It was in a small pot and the blooms were wilted, but a lovely purple color. I have always admired hydrangeas but don't know much about them...I don't have the greenest thumb so I tend to admire plants from afar but am too afraid to try growing them myself. Anyway, I took pity and bought this one. I immediately put it in a larger pot with some hummus, manure, and potting soil mix and gave it some miracle grow. It looked good the next morning, but by evening the buds were droopy again. I thought maybe it got too much of the hot afternoon sun, so I moved it to the front porch area which gets sun until around 1 and gave it some more water. It did the same thing yesterday, the buds looked good in the morning but drooped by late afternoon. My mom thought that hydrangeas needed a certain type of nutrient (she thought maybe nitrogen?) but I can't find anything about that online. Do they need nitrogen? I have some Milorganite (for my daylilies, which I can't kill so I love), would that be better to put on this hydrangea? Is there something else I should do for it? I should note that I don't plan on leaving it in the pot forever, but it will probably have to stay there most of the summer since I don't have a permanent spot and I don't want to uproot and rearrange my daylilies just as summer is kicking off...

I think it wants shade - probably the most full shade you can give it in Missouri. Submerge the entire pot in water (with water totally covering the pot) and leave it for an hour. It still may have drooping leaves by night time as it has to get used to a new pot and new soil. Now is not the time to try out various foods - it's in the recovery mode. No Milorganite, no food, just water.

Thank you Arlene. Should I submerge the pot everyday? If so, for how many days in a row will I need to do that? I should also say that I left the soil from the previous pot with it but gently broke up the root ball when I put it in the pot...same thing I do with geraniums or petunias when I plant them.

You did the right thing by breaking up the soil.

Try soaking it for an hour at a time for two days and let us all know your progress. Good luck.

I submerged it like this...

But the water is no longer over the rim of the pot after about 30 minutes...should I keep refilling it?

Also, these are the blooms...

Any idea what type of hydrangea this is?

Yes to refilling the bucket. You can help weigh down the hydrangea with a brick or two.

I think I have one similar but would rather wait until yours revives before I give out a name that's incorrect. Now I'm thinking of Ayesha (blooms either pink or blue depending on the soil acidity) but I'll wait for your photo .

Thank you so much @pirl for the great advice! My hydrangea looks so much better. I soaked it twice and moved it to an area with full shade. It may also help that we have had a couple storms with lower temps the past two days. Here's what it looks like now...

I am in love with the verigated colors of the blooms and the green interspersed. I hope this plant stays happy in my garden for many years Lovey dubby

So glad it turned out so well for you!

It will be happy for many years (I have a few that are over 60 years old) and won't want the sun your daylilies want. Give it a shady spot with a little morning sun, if possible.

I plan to leave it in the pot until the end of summer. I will take that time to decide which part of the yard it likes best. I need to rework my front garden area which gets morning sun but is usually shaded by 1. We'll see. Or it may just need a whole new bed in a shadier area, which will give me an excuse to buy other flowers to go with it Rolling on the floor laughing

Can you explain to me what submerging the pot does for it? I'm thinking it loosens the soil so the roots can reach out better but that's just a guess. Does submerging help other plants that are being transferred to bigger pots? I bought a palace rose (also purple) along with this hydrangea and wasn't sure if submerging would benefit it...?

Lastly, do you still think this is "Ayesha"?

The hydrangea may get stressed from being in a pot so long. I have had hydrangeas in the front in a former home and didn't like the "dead" look from November to May. Try for an east exposure.

This link explains the problem of trying to rehydrate any plant that has gone dry too long:

No, I doubt it's Ayesha but there are so many beauties that you can use a rainy hour (or day) to look at hydrangea sites to try and find a match.
