hi all. I grow a lot outdoors but am new to indoors besides orchids. My fiance ordered an indoor plant garden from proflowers for me it came with 2 calla lily plants and 2 mini rosebushes. I put the pot on my bar top counter because it gets good sunlight there. The next morning I went to my kitchen and noticed that a bunch of stems had fallen off of the calla lillies and the bottoms were slimy and some of the rose bush leaves had fallen off and the top of the stems were turning brown. I still hadn't watered the plants because the soil was moist still. I did notice that there were a ton of roots on the calla lily plants in the pot coming out of the top of the soil so I thought that maybe they need more room. So I found a square container that could fit all the plants and give it more room. I used miracle grow moisture control potting soil and transplanted the calla lillies and mini rosebushes into one bigger container with room for some growth. But still, the lillies are falling apart and the rosebushes have too. I have only put a small amount of water in this pot. I grow roses and veggies and all kinds of stuff outdoors but haven't ever had anything like this happen and am unsure what to do, if anything to save the plants. I sent pictures to proflowers and they sent me a new garden with 4 different kinds of plants but I only got those yesterday however they look yayyyy healthier than what I recieved before. Any help anyone could give me would be great! I'd really like to save them, if possible. I am also gonna try to post pics. I tried uploading but they are too big so I uploaded on photobucket. If they aren't working please let me know.

this was taken the morning after I got the plants.

this was taken yesterday, these stems had fallen off by the time I got home from work.

this was taken today. 8-17-17

this was taken today and is a pic of the replacement they sent, as you can see it looks soooo much healthier than the one I got before.
Thanks for any help anyone can give me. I really do appreciate it.
