These three indoor potted plants were given to me. They have bloomed and are now beginning to go wild and lose leaves. With the lily, how do I transition these to clay pots? Do I place them outside or keep them inside in clay? They look as if they are beginning to die. They are wilted and losing leaves. The Rose bush is the only one still flowering, but I'm afraid it will begin to follow after blooms die.
The lily and the tulip are just following their natural life cycle. This article will help with them:

What fruit producing vines can be grown in a container garden? Are there any vegetable producing vines that can be grown in a container?
Any plant can be grown in a container, as long as you provide enough water, light and nutrients. Almost all vegetable vines do well in containers and are easy to care for. Fruit vines tend to grow quickly and are perennials, so the need plenty of water and nutrients, but are still rather easy to care for.
Each time I put in new plants in my yard, they seem to die. I use potting mix and vitamin E on them. Should I first dig in chicken manure or some other type before planting? Also, I buy six plant containers. Should I loosen or cut off some of the roots before planting?

Can I plant a small tree in a container that is sunken into the ground, so as to contain the roots?
While you could attempt this feat, it may not be a good idea, as the tree may eventually outgrow the container and require digging up to repot--quite a task for in-ground potted plants. The following articles should be of some help to you: https://www.gardeningknowhow.com/special/containers/how-to-grow-container-trees.htm

I have heard about three major ingredients (peat moss, vermiculite and perlite) in soilless potting mix. What are they? How do they help in plant growth? How does one check for the right qualities of these products? If not available locally and easily, could they be replaced with the other materials (i. e. could a good potting mix be made out of organic composts, manures, oilseed meals, newspaper/white paper shreddings, natural mineral rock powders [limestone, rock phosphates, dolomite], etc) for making homemade potting mix? I shall appreciate the tips on homemade potting mixes without the use of moss, vermiculite and perlite.
