Hey everyone! I'm very much new to gardening outdoors, have plants inside but outside is a whole new ball game! I have 2 raised planter boxes in front of my house that get full sun facing West so I'm planning on filling them with lavender, some succulents and other whimsical drought tolerant plants! My wife was amazing and bought a bunch of Miracle Gro Garden Soil All Purpose For In Ground Use. I know this isnt ideal for the plants I want to plant so I was wondering if anyone could recommend what I can mix with this to make it the perfect soil for my plants! Thanks so much :)
