Ficus Elastica soil, watering, separating question
Hi I have never owned a plant, and I just bought 3 Ficus Elastica in a 10" diameter pot that are about 11" tall from Home Depot. I have never owned a plant or tree before and have been researching how to take care of it for the last 2 days. So much more is involved than I thought! It's kind of addicting reading all the posts, but fun. I have a few questions. I'm in area 9 (85028)
First I bought it as a plant to go in my room. While researching I realized this was three trees in one small pot. I think once they get bigger it would be nice to plant them outside in the yard. Will waiting before separating them cause problems? I think I read in a post that it wouldn't be too much of a problem to cut the roots as long as they have a lot of vitality? A follow up question would be if they should be separated sooner rather than later, should I give it a little time to acclimate to their new home before separating them?
Second I asked at Home Depot when I bought it how to take care of it and they taught me how to put it into a pot and put new soil in it. Unfortunately they told me to put a drainage layer in it. So I put about 1/2" of gravel at the bottom of the pot and the soil is, "MiracleGro Moisture Control potting mix". The ingredients are sphagnum peat moss, forest products compost, coir pith fiber, perlite, a wetting agent, and a fertilizer. I got this because they said it would help me to maintain the correct amount of moisture since I am new to taking care of plants. After research, I see the benefits of making your own soil so that it can drain quickly. So the question is can/should I wait until it is time to repot it to change to a faster draining soil, or do I do it now?
The third question is about drooping leaves. I put it in the new pot and soil on the 25th (two days ago). I had it to the side of my west facing window. I read how Ficus Elastica love sun so last night I moved it directly in front of the window. I noticed that the leaves are drooping now. The soil is still somewhat moist, but I'm not really sure what the cutoff between moist and dry soil is either. Do you have any insight to why they are drooping and how to fix them?
That last question gave me a fourth question. Please correct my understanding if it is wrong. I am supposed to saturate and then also put extra water to flush the soil everytime I water? And I am only supposed to do this after the soil is dry so that the roots get air?
Thanks in advance for your answers.
