20 DIY Self-Watering Planters That You Can Craft Today

Plants don’t normally require a lot of care and are great to have around for numerous reasons. However, there’s a problem. What will you do with your plants if you have to go away for a few days or more? They’re like quiet pets which you can’t take with you on trips and which have to be watered on a regular basis. The solution is quite simple: DIY self-watering planters. Yes, there are quite a few fancy self-watering planters available in stores as well but they tend to be pretty expensive whereas these ones are super cheap and easy to make.

DIY Self-Watering Planters

There are so many benefits to using a self-watering planter, especially for indoor gardeners looking to save time caring for their plants. The overflow hole helps to prevent root rot, which can sadly kill off your houseplants. This hole also helps to empty excess water that accumulates, minimizing the risk of this occurring. They also offer a much more efficient use of water and will avoid water wastage. Some self-watering planters offer users a moisture-wicking system, which can help to further improve efficiency.

Water delivery using any of these devices on our list today will be more targeted than using your regular watering can or spray bottle. You’ll find it’s far less wasteful as you aren’t spraying water around that doesn’t make it near your plant. Self-watering planters also give even moisture levels, and the water will go straight to your plant’s roots. These methods also help to minimize the risk of fungal diseases, making houseplants live longer. You won’t oversaturate the leaves, which is a top reason that plants develop these diseases.

You can also use any of these self-watering planters to feed your plants nutrients or food as well as water. The slow-release of these nutrients can help them to thrive for three or four weeks. If you live in an area that experiences a lot of hot weather, you’ll want to be careful that the water doesn’t evaporate after you’ve made your new self-watering planter. This sort of defeats the object of the device, and makes it difficult to use if you are traveling or away for a while. They also aren’t ideal for all types of plants but are great for tropical plants and vegetables. However, species that need to be kept in very moist soil will struggle with a self-watering planter.

A lot of the DIY self-watering planters on our list are made from recycled bottles. The tutorial from craftyourhappiness shows how you can make such a planter out of nothing but a plastic bottle and a piece of string. Cut the bottle into two sections, make a hole in the cap and run the string through, put a few stones and soil into the top section, add the plant and then place this upside down into the bottom half of the bottle which is filled with water.
