Planter Reservoirs

Add a self watering reservoirs to window boxes, pots and planters, and ensure plants are always hydrated just the right amount. In container gardening a planter reservoir is an easy way to cut down on manual work while improving the health of roots. Each water reservoir insert featured below is its own self watering conversion kit that turns regular containers into nourishing plots for favorite arrangements.

Even though it's just an insert, reservoirs are really self watering conversion kits for containers. Make any vessel a self watering planter with reservoir inserts designed to provide the perfect amount of water to root balls while leaving room for soil. A gravity fed capillary is at work between the water volume and soil volume, making each self watering reservoir a well of nutrients for plants to draw on as needed, irrigating for weeks at a time depending on climate and plants used. Buy self watering planter reservoirs online, or call weekdays for assistance choosing the right size for your containers.

How to Use Self-Watering Reservoirs in Planters:

Step 1: Place a thin layer of gravel at the bottom of the planter. This will provide emergency drainage in case of over-filling.
Step 2:
Place 1"-2" of soil over the gravel, and then place the self-watering reservoir on the soil base. For very large planters, connect multiple reservoirs with linking units.
Step 3:
Insert the fill tube into the reservoir and trim so it is 1/2"-1" above the top of the planter.
Step 4:
Fill the planter with soil to the desired level. Tamp it down but do not pack it firmly.
Step 5:
Add plants as usual. You can hide the fill tube if desired, but make sure you can easily pour water into it.
Step 6:
Water the soil thoroughly and add water to the fill tube until the reservoir is full.
Step 7:
As time passes, add water to the fill tube as necessary. Usually, it will take the plants 1-2 weeks to use all the water in the reservoir.
Step 8:
Enjoy your plants as they grow healthy and strong without worry of over- or under-watering!

Different types of reservoirs

DIY Self Watering Planters Made Possible with Our Reservoir Inserts

Get a self watering conversion kit to maximize the efficiency of pots and window boxes. Container gardens thrive when on a schedule, and a self watering reservoir helps to achieve that consistency. With a planter reservoir insert safely housed beneath a layer of soil, root balls are able to drink through a gravity fed capillary process. This is a very natural way for plants to hydrate and thrive!

Existing container gardens are easy to repot using a planter reservoir and the benefits are immediate. As soon as window boxes and other planters are fitted with a self watering reservoir they can begin to absorb liquid as needed. This process of "drinking up", so to speak, also creates a means for plants to store excess moisture that runs off from rains, only to be nourished with it at a later time.

Provide Gallons of Water for Plants, Sub-Irrigated

Use a planter self watering conversion kit for all your favorite outdoor arrangements, and for indoor plants as well. Each reservoir insert acts like a miniature water tank that can be easily removed and adjusted for different seasons. This method of self-sufficient watering can also prove invaluable for hard-to-reach second story window boxes or hanging plants. With a variety of sizes and shapes available there are planter reservoirs to match most any container. Our reservoirs hold generous amounts of water lasting weeks between refillings, unlike lesser products on the market which use small, flimsy PVC pipe that requires refilling daily. Each of our reservoirs reaches up to 9" past each end. Meaning, a 31.5"L Reservoir is recommended for window boxes up to 49.5" interior length.

Plants in containers and window boxes are more prone to drying out than ground plants because of their removal from the natural system of ground water and rain. A self watering conversion kit ensures that at-risk plants receive adequate levels of moisture to mimic a more natural watering cycle. All the gardener has to do is monitor levels and replenish as needed.

Insert self watering reservoirs into pots and planters and immediately begin regulating the amount of water your plant receives. Simply fill the reservoir and surround with soil, plants and flowers. Each planter reservoir is capable of providing moisture to roots planted within nine inches, so keep this in mind when selecting a size. Once in place, occasionally refill reservoirs and allow the sub-irrigation system to work its nourishing magic.
