1.What should I do now with plants potted in containers? Is adding
standard 15-15-15 fertilizer enough for that?

There are a lot of variables to picking the right fertilizer - the
type of soil, average temperature, amount of rain, how many years you
have been fertilizing the same garden, etc. I have started using the
slow release type, adding about 1/2 cup to each hole before putting in
the plants. The slow release type prevents burning the plant and feeds
over a longer period of time.

2. When next time I prepair soil for containers. I usually mix half a
soil from the ground and half the compost I got from the dump. Should I
mix 2 parts compost to 1 part soil?, So I do not have to add fertilizer
right away after planting?

The primary purpose of adding compost is to keep the soil loose so that
air & moisture can reach the roots. If the soil is already loose,
adding more compost does not provide much benefit.

Just my two cents worth. Go for fish emulsion or seaweed extract. Just
follow the directions on the bottle. They are nearly fool proof, which I
personally find a great advantage. Make the teensiest little mistake
with chemicals, and it's "ciao baby" for your plants (they're toast).
The next time you pot, or re-pot, you might try dog or cat fur. Put in
some potting soil, place the fur on it, put your plant on top of the
fur, fill in the edges with potting soil, and your good to go. It's
solid protein (nitrogen compound) that breaks down slowly, for long,
slow, continous feeding.
