Central Sierra: Tech Can Help You Build a Smart Home Garden
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.

Central Sierra: Seed Starting Using the Winter Sowing Method
Central Sierra: Take Advantage of Winter Dormancy for a Gorgeous Spring Bloom
Winter Dormancy: Gardening For the Fourth Season
The winter holidays are just around the corner, and hopefully you have your garden in order. Spring bulbs are planted. Garlic and potatoes are in the ground. Your garden has been “put to bed.” Tools have been sharpened and put away. Tender plants are mulched and waiting for the anticipated winter rains. Most plants are entering their dormant cycle and you, no doubt, are ready to join them.
Not so fast! Winter in the garden is a time for planting, pruning, and planning.
Take advantage of winter dormancy with bare-root plants
Now is the time to take advantage of winter dormancy. From December through March, your local nursery will have bare-root plants. These are plants that are dug while they are dormant, and they will have their roots exposed. Often, they are more affordable than containerized plants, and they are easier to handle.
You’ll find fruit trees, cane berries, asparagus, artichoke crowns, rhubarb, kiwi, strawberries, grapes, roses, and vines available as bare-root plants. Check with your local nursery early and after the first of the year. This gives you an opportunity to plan your location, prepare the planting hole when the ground is pliable but not soggy and get ready to welcome some new plants into your garden.
Understand the best time to prune
Mark your calendar: January is time for winter pruning, but you’ll want to plan and space your tasks between bouts of precipitation. Perennials that weren’t cut back in fall should be pruned in January. This is also the time to prune cane berries.
Fruit trees require pruning to shape the tree and open the tree center for the spring growth. If you already have fruit trees, January is the time to apply horticultural oil to control scale, mites, aphids, and other insects. Once again, check the weather and make certain that there are at least 24 hours of dry weather around the application.
Design with plant rotation in mind
Now before you relax and reach for the seed catalogues, grab a sheet of paper and make a quick drawing of last season’s vegetable and annual garden. Note where you planted each plant family and think about where you can rotate your plantings for the upcoming year. Plant rotation is an important step in sustainable gardening. Plant rotation builds and sustains helpful soil microbes, reduces the spread of soil-borne disease, helps plants take in more nutrients, and makes for a healthier garden.
The goal with plant rotation is to avoid planting the same plant families in the same location year upon year. Ideally, you will rotate plant families from one bed to another over at least a four-year period.
Planning is important before you shop those seed catalogues, because you don’t want to plan for too many tomatoes or melons if you haven’t set up a good rotation. Learning to identify which plants belong to the same family is your initial task. Tomato, pepper, eggplant, and potato belong together. Cucumber, melon, squash, pumpkins and gourds are related. Cabbage, broccoli, Brussels sprouts, kale, cauliflower, radishes are another family.
Once you have your families grouped and a rotation schedule established, you can finally kick off your shoes, surround yourself with your seed catalogues, and slip into the gardeners’ relaxed winter dormancy and dream of spring.
