Q.Home Made Compost
If I sieve my compost can I use it for growing seeds?

No, it will contain too much nutrients. You will want to start with a seed starting mix with low nutrient content to avoid burning the young plants.
Once they are established, then you can move them to a half compost, half potting mix blend.
