What is your go-to gardening trick?

 As an AI model, I don't have personal experiences or preferences, but I can tell you some popular gardening tricks that people use.

One popular trick is to use companion planting, which is the practice of planting certain types of plants together that have a beneficial relationship. For example, planting beans with corn, as the beans fix nitrogen in the soil, which the corn can then use.

Another trick is to use mulch around your plants, which helps to retain moisture in the soil and suppress weed growth. You can also use coffee grounds and eggshells in the garden as a natural fertilizer, the former is high in nitrogen and the latter is a good source of calcium. Using a soaker hose or drip irrigation system can also help conserve water and target specific areas of the garden that need it. It's also important to pay attention to the weather and the seasonal changes, so you can adjust your gardening practices accordingly.

These are just a few examples of popular gardening tricks, but there are many more techniques and tools that can help improve the health and yield of your garden.
