Get garden soil. Mix half native soil and half purchased soil to fill in around a new plant. Cover the top of the garden with mulch. Think of mulch like long term fertilizer. The soil's microorganisms break it down and turn it into food for your plants. Mulch twice a year about six months apart. Mulch also regulates soil temperature and holds onto water in a beneficial way for your garden. Be aware of the quality of light your plants need and where in you place them. It matters. Morning light is generally better than intense afternoon light. Some plants are tolerant of that intense light, but not all. Be aware that you may need bug killer down the road. It takes time to build up native soil to be good for planting. Keep on nourishing it. If the garden doesn't take hold that first year, take heart. You're building up the soil for the next year. New plants generally need more water for the first week or so, then tapers off. Give yourself a break with planting. You're learning. Experiment
Mix in anything organic.it will help break up the clay.
I would recommend going into the IFA store... They'll have some people there who will tell you what to mix your soil with. Not being a garden expert, I know they recommend a compost, peat moss, or manure additives to help the soil. I know there's a new IFA store in the American Fork /Lehi area in case you don't want to go to Provo.
