Newly installed trees are often monitored for water needs by several types of plants. Ajuga, impatiens, and coleus are excellent plant watering indicators. They are susceptible to water loss and will exhibit obvious signs such as wilting and browning of leaf tips. This will tell you the area is dry and you need to water. As any soil moisture meter can handle the looser potting soil used for indoor plants, the probe is a greater concern for outdoor plants. However, regardless of the meter type, it’s best not to thrust the meter into soil with a lot of force. If users detect considerable resistance in any soil type or texture, remove the meter and try a different spot.

While some gardeners may want the higher degree of accuracy that comes from a calibrated digital meter, the sturdiness and ease of use of the Xlux meter make it a winner in our book. Except for moisture meters that are designed for continuous monitoring of soil conditions, you should not leave your moisture meter inserted into the soil for more than a few minutes while you get your readings. Leaving the probe in the soil for too long can damage the device.

Most self-watering planters use a reservoir system to collect extra water and store it for later use. The plant takes in water by direct absorption from the soil and roots, or from a rope or other material to bring the water up. The reservoir's water capacity varies from a few ounces to more than half the size of the planter. The amount of time the water lasts depends on the plants and growing conditions, but most hold the water from a few days to a few weeks. For example, our best window box option, the Mayne Fairfield Window Box Planter, has a reservoir that can hold up to 3 gallons of water. The frost-free resin accounts for a higher price point, but this quality material should hold up for the long haul, so we think it’s still a great value. You should look forward to years of growing in this planter without having to worry about warping, fading, or other damage. It is styled to resemble copper but at a fraction of the cost and with the convenient addition of the self-watering feature.

The unit has a button on the front we could switch to select from the three functions, and the readings were near instantaneous, which was impressive. The only slight downside was that one of the copper probes seemed a bit loose, so we had to take care when inserting the probes in the soil. Accuracy is obviously of value in a moisture meter. For the most accurate reading, consider a digital moisture meter. Some digital meters show soil moisture levels to a decimal point or percentage, making them more accurate than an analog meter with a 1-to-10 scale. The indicator will tell you when your plant needs more water. A red window display means your plant needs water adding, blue means no water needed Water is vital to thriving plant life—plants would shrivel up and die without it—but ensuring that you provide the right amount of H2O can be difficult. Those new to gardening may often over- and under-water their plants, but even experienced green thumbs can mess up occasionally. Soil moisture meters are simple garden tools that include sensing probes that detect the level of dampness in soil. They’re touted as the best predictors for watering, so to see if they live up to the hype, we tested the most popular ones available. If you're looking to coordinate indoor planters with your decor, try the Bloem self-watering planters. They come in four colors: pebble stone, charcoal, misty blue, and merlot. All colors are muted and complement a variety of plants and decor styles.Hydroculture plant roots have been specially adapted to grow in hydrogranules, which creates a smaller, more fleshy and hardier root system. This results in mature plants being available in smaller grow pots than their soil based equivalents. How do I choose the correct sized decorative pot to fit my houseplant? Upon opening the box containing the Ecowitt Soil Moisture Tester, our first thought was how different the probe looked compared to all the other tester probes. Instead of a long round cylinder, the probe on the Ecowitt was flat and short—just 3 inches long.

To use this planter, simply fill the reservoir in the bottom before potting your plants. Once they are planted, water the plants, as usual. Any excess water collects at the bottom of the reservoir or drains out the drainage holes. The plant can access the collected water with its roots when needed. This is an indoor/outdoor planter but is particularly great for outdoor use, due to the included drainage holes. When it rains, and excess water abounds, it simply drains out the bottom after enough has been stored in the reservoir. Yamasaki, S.; Dillenburg, L.

There is no water level indicator, and the self-watering feature collects extra water, storing enough for just a few days of watering for most plants. We like this for indoor plants to take center stage. The planter does have UV protection, so you shouldn't need to worry about the color fading in bright sunlight.

Drainage: Traditional indoor plant pots have drainage holes and stand in saucers to allow excess water to drain freely. For modern decorative plant pots without drainage holes the grow pot could be stood inside the pot on a saucer, or in a pot liner for extra protection. Alternatively, for a professional design look, the plant can be repotted directly into a pot liner with a layer of hydrogranules to provide both a drainage layer and a reservoir for the plant. The roots above the granules will pull the water gently out of the granules (capillary action) to keep them moist but not wet. For instance, a house plant with dry soil and wilting leaves is a plant that needs watering. However, a plant with wilting leaves and very wet soil will most likely be suffering root rot from overwatering.Indicator plants that are used as a water indicator for plants can also pinpoint excess moisture in the area. Indicator plants must be common, easy to grow, hardy, and have a set bloom time. Plants which prefer to grow in arid area indicate the poor or very low moisture content in the soil. Sacchamm munja, Acacia nilotica, Calotropis, Agave, Opuntia, Argemone are such plants. Some plants grow in low soil moisture as Citrullus colocynthis. Eucalyptus lowers the water table. Echinops echinatus. Cassia auriculata are found in the area of deep water table. Typha, Phragmites, and Vetiveria grow in water-logged soil. Growth of Typha, Phragmites, Juncus and Carex indicates the swampy condition. Mangrove vegetation and Polygonum are found in water-logged saline soils.
