Both indoor and outdoor plants require a certain amount of water to grow healthily. If you often forget to water your plants or will be away for a few days, self-watering systems are available to keep your houseplants alive and thriving. Automatic watering systems for indoor plants are also convenient because you don’t need someone else to come over and check on them.

Buying Guide for Automatic Plant Waterers

To find the best automatic watering system for your plants, it’s important to consider factors such as capacity, timing mechanisms, and water flow. Here’s a brief description of each factor.

Capacity

Consider how many plants you need to water, as well as the size of the plants and how much water they usually take. While a single watering globe can only water one plant while you’re gone, a complete irrigation system could water 10-20 plants at a time.

Timers

Some automatic plant waterers have digital or programmable timers to control the frequency and duration of watering. Digital plant watering timers generally include more features and configurations, allowing you to conveniently set the unit and forget about it. Waterers with mechanical “timers,” such as water globes, provide users with more of an estimation as to how long the water will last. However, waterers with mechanical timers are often cheaper and require little installation.

Water Flow

Your plants will suffer if too much water is dispersed into the soil at once. If the water flow is too little, your plants will dry up. A system with an easy-to-adjust water flow is ideal if you’re not sure exactly how much water to give your plants.

Automation

All plant waterers in this review are designed to consistently disperse water when your plants are unattended. However, some systems can be connected to a spigot to continuously water your outdoor plants. Other products, like watering globes, can only hold a limited amount of water. Consider the watering schedule of your plants and how much automation is necessary for the best results.

How To Care for Your Plants While You’re Away

Watering your plants regularly is critical to keep them alive. However, there’s more you can do before you leave home to make sure you return to lush and healthy houseplants or outdoor plants. Here are some tips to care for your plants while you’re gone.

  • Set up your automatic plant waterer several days before you leave home. This gives you time to adjust the waterer to ensure your plants are receiving the appropriate amount of water.
    • You can use a moisture meter to gauge the soil moisture of your plants.
  • Orient your plants so that they receive the appropriate amount of sunlight while you’re gone. Keep in mind that the more sunlight your plants receive, the more water they’ll consume.
  • Prune any dead or dying foliage, as well as buds or flowers.
  • If you regularly fertilize your plants, skip the fertilizer until you’re home.
  • If using a self-waterer isn’t an option, “shower” your plants thoroughly before you leave. Many houseplants can survive just fine for a week or longer with one thorough watering.
    • When in doubt, too much water is usually better for plants than too little water.

Frequently Asked Questions About Automatic Plant Waterers

What is the best automatic plant watering system?

The best automatic plant watering system is one that works best for the type of plants you have, as well as the number of plants you have. If you have an outdoor garden, an automatic drip system that connects to a garden hose may be the best solution. Conversely, a simple watering globe could be best for a single houseplant, such as a pothos.

What are the different types of automatic watering systems for plants?

There are many ways to keep your plants watered while they’re left alone, although plant watering globes and spikes tend to be the most popular for casual plant owners due to their simplicity. Here are some other types of automatic plant waterers:

  • Drip watering systems
  • Self-watering mini plant pots
  • Self-watering plant pot reservoirs
  • Stackable self-watering planters
  • Vertical herbal garden walls

What are the pros and cons of an automatic plant waterer?

The pros of automatic plant waterers include their inexpensive price tag, configuration, ability to water multiple plants at a time, and simply keeping your plants alive while they’re unattended. The cons of using an automatic plant waterer include the potential for your plants to die if they receive too much or too little water.

How long do automatic plant waterers dispense water?

Automatic plant waterers tend to dispense water anywhere from one to two days or as long as multiple weeks. Systems connected to a replenishing water source may be able to water your plants continuously. No matter which automatic plant waterer you choose, each product is designed to only dispense small amounts of water at a time based on how porous the potting soil is.

What is a drip irrigation system?

A drip irrigation system uses a network of small tubes to send water to your plants from the source. The source could be a large bowl of water or a garden hose spigot.
