What This Means for Your Garden
The dominant soil in Houston, TX is Clay soil. Clay soils are known for being heavy and dense. They hold nutrients and moisture well, which is great for plants during dry spells, but they can become waterlogged after heavy rain. Working organic matter into clay soil helps improve its structure and drainage over time.
The pH in your area ranges from 5.6 - 7.5, which is classified as Near Neutral. This near-neutral range is ideal for most garden plants, including tomatoes, peppers, lettuce, and the majority of common vegetables and flowers.
Your USDA hardiness zone is 9a, meaning winter lows can reach around 20 degrees Fahrenheit. This determines which perennials, trees, and shrubs will survive winter in your area. Check the plant recommendations below for varieties suited to both your soil and climate.

- Coarse Sand — Improves drainage when combined with compost
- Aged Bark Mulch — Adds organic matter gradually as it decomposes
