One of the advantages in planting natives is that they ordinarily don't really need fertilizer, because they are already adapted to the climate, rainfall and soil where they are growing. Compost is a wonderful additive to the soil because it assists in drainage, but also helps to make vital micronutrients in the soil available to the roots. Since in Texas we mostly have alkaline soils, this is essential, as it is difficult for roots to access what they need in alkaline soil. If it would make you feel any better, you could certainly pick up an organic fertilizer at the nursery, only avoiding high nitrogen lawn fertilizers for blooming plants. Nitrogen promotes heavy leaf development, and is ideal for lawns, but if a plant puts too much energy into leaf production, the bloom quality and quantity can suffer. To further add organic material to your soil, try mulching with a shredded hardwood bark mulch. Not only will this hold moisture in your soil and protect the roots of your plants from heat and cold, but as it decomposes it will continue to improve the texture of the soil.
