Hey everyone! I'm gearing up to start my first flower garden this year in zone 7a and I'm really excited! But, I'm a bit confused about the different types of soil and materials like topsoil, compost, and mulch that I've been hearing about. I'll be creating an in-ground flower bed, so I plan to dig up the grass first. After that, what should I add to the bed to bring the soil level back up? My existing soil isn't great, so I'd love some advice on what I should use to get started!

So, here's the deal: Topsoil is basically just dirt, typically the first 6 inches from an undisturbed area. If you’re in a new build, a lot of that probably got stripped away. Compost is your organic gold — it’s made from decomposed food scraps, leaves, and even manure, giving your plants some serious nutrient boosts. Mulch can be anything from wood chips to grass clippings and is used to cover the soil around your plants.
For your flower bed, you'll want to mix in some good compost with topsoil after removing the grass. It helps keep the soil healthy and improves drainage!
Great questions! Topsoil is just that, dirt. It can even have peat or mulch in it, but make sure it's decomposed. Compost has a richer mix of nutrients, being made from stuff like manure and decomposed leaves. And beware of dyed mulches — stick with natural options.
When you dig up the grass, consider mixing about one part compost with two parts topsoil to raise the level. Mulch is awesome for helping with moisture retention and weed suppression too! Just make sure not to pile it too close around the stems of your flowers.
Label reading is key! Look for soil specifically meant for garden beds rather than indoor potting mix, which won’t work outside. Topsoil alone lacks nutrients, so definitely mix it with compost. When you dig up the grass, bring in a good garden soil mix that has some structure and nutrients.
After planting, a layer of mulch is perfect for retaining moisture and keeping temperatures stable. And don’t forget to add fresh compost in the fall and spring for ongoing nutrition to your flowers!
