Regularly observing your soil is an essential step in determining how frequently to water your plants. Environmental factors such as weather conditions can impact your watering schedule, so it's important to remain vigilant. One quick way to assess soil moisture is by using your finger to feel the top layer of soil. You can also use a soil moisture sensor with probes to accurately measure the moisture level. In addition, water-saving accessories like self-watering planters and trays can simplify the process and include water level indicators to alert you when it's time to water. By utilizing these techniques and tools, you can effectively manage your watering schedule, conserve water, and promote healthy plant growth.
