I live in CT and love snapdragons. I bought a flat and put some in a container and some in the ground. I fertilize both weekly with diluted liquid Miracle-Gro. The ones in the container are green and lush (but crowded) and the ones in the ground are thin and yellowing at the bottom. I snip them to try to make them not so lanky and I like snapdragons in the house. What should I do?

If both groups of snapdragons are getting the same exposure to sunshine and are watered and fertilized as needed about the only obvious difference in the growing conditions is the soil. It may be that the soil in your garden is not as rich as the potting soil and the roots are not growing out into the soil enough to produce strong and healthy plants. I don't know that there is much you can do to improve the soil now that the plants are in the ground but as you remove them and before you replace them with new plants, take the time to work some compost or other organic matter into the planting bed. Organic matter will loosen the soil for good root penetration, will help hold moisture near the root zone and will provide a constant source of nutrients as it breaks down in the soil. Best wishes with your plants!
