Technology for the Home Gardener 

Technology can help the home gardener in myriad ways. Technology applies scientific knowledge for practical purposes to solve problems and make life better. Technology is a tool for the garden and gardeners. We can use it to complete routine tasks or tackle more complicated matters, all in an effort to accomplish our gardening goals. 

Technology for the garden much of the time comes in the form of an app, short for computer application, which is software designed to perform specific functions. Apps are downloaded to computers and other electronic devices. Many apps use artificial intelligence (AI), a system that performs tasks without significant human effort or oversight. 

Smart weather stations give us timely, detailed information about our weather by tracking temperature, barometric pressure, wind strength and direction, rainfall, and UV rays. Originally, SMART stood for Self-Monitoring, Analysis and Reporting Technology, but today SMART is also a broad range of intelligence and advanced technology.  

A comprehensive smart garden integrates technology to streamline gardening processes to make them more efficient and sustainable. 

There are solar-powered smart irrigation systems that utilize our garden’s current weather data, using past microclimate temperatures and humidity. There are weather-based sensors that can help us apply proper irrigation to prevent over- and under-watering. The sensors are automated and can be adjusted for a plant’s age, the current weather and the condition of the soil. There is an app that tracks sunlight. 

Healthy garden soil is essential and there is technology that can determine soil texture. With that information, we can learn about our soil’s water drainage and retention, workability, and nutrient retention. Also available are soil monitors that can measure soil moisture content, pH, temperature, and natural nutrients. 

With a detection app, we can know when a critter visits our garden. Early detection may prevent damage. There are apps to determine whether it is a pest or a beneficial. If it is a pest, we can utilize a pest management app and / or visit the UC Master Gardeners of El Dorado County website to learn about research-based management, control, and treatment for natural solutions to create a more sustainable garden. 

There are many plant recognition apps that operate from our photos of a plant’s leaf or flower or a succulent, cactus, or mushroom. Utilizing again our own photos, there are apps to identify and diagnose plant needs, problems, and diseases. 

Living in the foothills, we might want to use an app that will alert us of an upcoming temperature drop. We can plan our garden with a planning app to place the right plant in the right place, that will strengthen the likelihood of a thriving garden. There is technology for all facets of composting. Robots can assist in producing and weeding vegetable gardens and can mow our lawn. 

We would be wise to use the tools of technology that were developed specifically to help us have beautiful and healthy gardens.
