Hi First Time
You did ok!
You made an open all purpose mix.
Open mix works better for me.
As far North as you are, it will help keep the winter rots
away with the gravel and bark by keeping the water moving.

What type of plants?

The perfect mix isn't as important as knowing what conditions your plants like and supplying them!

WHAT you use as a grow medium is extremely important in establishing the degree of satisfaction your growing experience will ultimately offer. The soil is the actual foundation of each of our plantings that utilize soil. In the same way we bring trouble upon ourselves by building a building on a weak or inadequate foundation, we can expect frustration to regularly be visited upon us in plantings grown in inadequate/inappropriate soils. Most of the troubles people write about on this forum can be blamed squarely on an inadequate soil - even things like insects/disease, soluble salts accumulation, diminished vitality - ALL, are more often than not, the result of a poor soil.
