How can I plant silk flowers for outside use?

I have just stuck artificial flowers in the dirt of the planter....make sure there is good drainage..... Cover with small stones or moss if you want to.

I often use spaghum moss, any compost, or straw or hay—even Easter “grass”. The foam is great, but if the container is full of rocks and dirt, I just stick the stems in the ground. When I use silk flowers I chose for a specific color, I use spray polyurethane to help water/sun proof the flowers, but even in the Texas sun, they always last one season, and most of the time, a whole year. Best jonquils I’ve ever grown!

Silk although not really waterproof, does take well to:

A. Polyurethane or Weather Sealant

B. Weathering, As long as you wash them regularly, and expect to replace them each 3 years or so.

Avoid: Paint, Stain, Lacquer or FlexSeal as those will prone to crack.

My mother sticks artificial flowers right into the ground. As long as the stems are long this works well. If they're in the sun there will be fading over time, but the flowers are easily replaced.

Agree with Jewell about spraying them with a clear poly UV spray. We also spray our outdoor wreaths on both sides with clear UV poly spray. Makes everything last longer. You can find good buys on end of season silk flowers and bushes. Have fun!
