6 Best self watering Spikes in 2021 – The Buying Guide & Reviews

When you are planning to be away from home for a few days, one of your worries would be that you might return to a garden of wilted or dead plants. You would typically request a friend or a neighbor to perform the task of watering your plants for you during your absence.

How convenient would it be if you had a way of making sure that your garden does not miss its daily quota of water, without your having to entrust the responsibility to someone else?

There is a solution that can enable you to do this and it is called drip irrigation. It is a slow-release mechanism that drips water into the soil to keep your plants consistently hydrated over a period of time. When small areas are irrigated with low rates of water flow and pressure, it is termed micro-irrigation.

This is the concept that is used by self watering spikes to maintain a sustained supply of water to a home garden.

How do self watering spikes work?

To set up a drip irrigation system for a collection of potted plants or a garden of flower beds, self watering spikes are inserted into the soil and intermittently filled. Inserting them in the soil makes it possible for the watering system to directly access the root system and guarantee effective hydration with minimum water wastage.

A few different models of watering spikes are available, but they operate on the common principle of trickle irrigation.

  • Some of them come equipped with a receptacle for the water and some are watering spikes for bottles, which require you to mount a bottle of water onto them;/li>
  • The spikes could be made from plastic, with a hole for the water to drip through, or they could be made from porous terracotta or ceramic, through which the water seeps into the soil;
  • Some spikes come equipped with a hose that is connected to a water supply or reservoir and some have a valve that can be used to adjust the drip-rate.

Whichever type of spike you use, it will help keep your plants watered in an efficient and targeted manner over an extended period of time, with minimal or no intervention from you.

A few models of watering spikes are a cut above the rest in terms of popularity. The main features of these watering spikes are discussed below.

This is one of the best self watering spikes for outdoor plants as well as indoor plants. It comes outfitted with a few extra features that prevent some common issues with a basic model of self watering spikes.

  • The spike is inserted into the soil at the desired depth, and a bottle of water is secured to it upside down so that the water flows into the spike and is released into the soil in drips;
  • You can repurpose used glass or plastic bottles as water reservoirs. It is compatible with bottles of varying sizes and shapes;
  • An additional shorter stake or spout provides added stability so that the spike does not keel over due to the weight of a heavy bottle. But the main purpose of the stake is to prevent drip stoppage from the main spout by being an additional outlet for the water;
  • An anti-tilt bracket at the mouth of the spike also prevents the system from leaning under the weight of a large bottle;
  • A valve helps you set the drip-rate. Some plants may need more water or more frequent watering than others. Through trial and error, you may test the drip rate of the spout and set it up to water your plants accordingly. This helps you customize the system for specific plants for targeted watering. It also helps you set it up for a specific number of days within the range of two to fifteen days;
  • This spike is relatively inexpensive and good value for money;
  • Its compact size and design make it a versatile choice that can be used in pots of varying sizes, hanging baskets or beds.

Self watering terracotta spike. Made of terracotta or clay, this slow-release watering spike releases water through its porous surface. It can be fragile but effective in keeping your plants hydrated and the soil moist to the optimal degree.

  • Terracotta watering spikes operate according to the law of osmosis. If the surrounding soil is dry, the water they contain wicks into the soil through the porous clay barrier in an attempt to equalize the moisture content on either side of the terracotta surface;
  • Conversely, if the surrounding soil is too wet, the terracotta surface will absorb the excess moisture. Due to this property, terracotta spikes are naturally self-regulating water release devices that prevent over-watering;
  • Long-neck bottles like wine bottles are the ideal reservoirs for these spikes since the long and narrow bottlenecks fit comfortably and securely inside the mouth of the spike;
  • The ideal depth to which you should insert the spike into the soil is up to 7/8 of its length. But if the bottle is heavy or full, it is advisable to push the spike all the way down to its brim for better stability;
  • The spike does not have a regulating valve but it can typically water a plant for seven to ten days using one liter of water;
  • It is environmentally friendly since it is made from a biodegradable material like clay.

Plant watering spike. Made from ceramic, this watering spike is also naturally self-regulating like terracotta. Water seeps out of it or back in depending on the moisture content of the surrounding soil, thereby maintaining a balance on either side of the ceramic barrier.

  • The device has a simple and easy assembly consisting of a ceramic spike and a cap;
  • The cap is designed to securely fit the mouth of most average-sized bottles;
  • The spike and cap have to be immersed in a bowl of water, filled and closed underwater after air bubbles are knocked out;
  • Piercing the top of the bottle to make an air hole ensures an uninterrupted flow of water from the bottle to the spike;
  • The long spike allows you to choose the ideal depth at which to affix the spike. For tropical plants, which require moist soil and more water, you can insert the spike at a shallow depth so that more water flows out of it due to gravity. For plants like cacti, which need drier soil, you can insert the spike deeper.

The spike is made from terracotta, so it is advisable to soak them in water for an hour or so before they are inserted into the soil. This pre-treatment will help open their pores and ensure that they do not pull too much water at once from the reservoir due to their dryness;

  • Long-neck bottles like wine bottles are the ideal choice as they will comfortably fit into the spike far enough to keep the entire setup stable and balanced;
  • The spike will water your plants for seven to ten days on average;
  • Plastic bottles may be a better choice when compared to glass bottles. Plastic bottles are lighter and will bring down the overall weight of the reservoir. A lighter reservoir will safeguard the clay spike from breakage.

Self watering spikes buyer’s guide

How do watering spikes work? Most spikes operate according to one of the two principles of osmosis or drip. Since a variety of designs are available, you can choose the spike that is most suited to the needs of your garden.

  • For plant beds and large pots, consider buying longer spikes. When the reservoir needs to be large and contain a large amount of water, a longer spike can be driven deeper into the soil to better support the reservoir and keep the setup stable;
  • If you have plants with very specific watering needs, consider buying a spike with a regulating valve to set the drip-rate. With an adjustment valve, you get greater flexibility and can manage the irrigation to a finer level of detail;
  • For plant beds and larger plants that require more water, or for extended irrigation periods, consider buying a spike onto which you fit a large bottle. It is a better alternative than an attached bubble reservoir, which will hold significantly less water;
  • Spikes with attached reservoirs are more suitable for pots, hanging baskets and shorter irrigation periods, as they hold less water.

In conclusion, a self watering spike is a simple, inexpensive way to automate the watering of your plants so that it takes the burden off you to an extent, especially in your absence. It is a worry-free way of ensuring a steady supply of moisture to your plants.

It is also a good solution to the problem of keeping your plants hydrated when you need the surface of the soil to be dry and treated with pesticides.

Apart from water, the spikes can also be used to supply nutrient solutions to the roots.

It is an eco-friendly way of maintaining your garden and keeping it lush, verdant and colorful.
