What Are Self Watering Planters?

Self watering planters are innovative gardening containers that automatically deliver water to your plants through a built-in reservoir system. Unlike traditional pots that rely on top-down watering, these planters use capillary action or wicking systems to draw water from a reservoir directly to the plant roots as needed.

How Self Watering Planters Work

The magic of self watering planters lies in their use of capillary action – the same principle that helps trees draw water from their roots to their leaves. Here’s how the process works:

1. Water Storage

The reservoir at the bottom stores water, creating a constant supply that’s separate from the soil compartment.

2. Capillary Action

A wick or wicking material draws water up from the reservoir through small pores or fibers, similar to how a paper towel absorbs spills.

3. Root Zone Delivery

Water is delivered directly to the root zone where plants need it most, ensuring efficient uptake and minimal waste.

4. Self-Regulation

Plants only take what they need, preventing overwatering while ensuring they never go thirsty.

Complete Setup Guide for Self Watering Planters

What You’ll Need

• Self watering planter
• High-quality potting mix
• Your chosen plants
• Water for reservoir
• Measuring cup
• Gentle fertilizer (optional)

1. Prepare the Planter

Clean your self watering planter thoroughly with mild soap and water. Rinse completely and allow to dry. Check that all components are present and functional.

Pro Tip: For new planters, soak any wicking material for 30 minutes before use to ensure proper water absorption.

2. Fill the Reservoir

Fill the water reservoir according to manufacturer instructions. Most systems can hold 1-3 cups of water. Use room temperature water for best results.

Important: Don’t overfill – leave space for air circulation and expansion.

3. Add Growing Medium

Use a well-draining potting mix that retains moisture without becoming waterlogged. Avoid garden soil, which can be too heavy and may clog the system.

• Fill to about 2/3 capacity initially
• Leave room for root growth
• Gently tap to settle, don’t pack tight

4. Plant Your Selection

Whether you’re growing tomatoes, herbs, or houseplants, plant at the same depth as their original containers. Water lightly from the top initially to help establish the root system.

First Week: Water from the top until roots establish contact with the wicking system.

5. Monitor and Maintain

Check the water level indicator weekly and refill as needed. Most self watering planters need refilling every 1-2 weeks depending on plant size and environmental conditions.

• Check soil moisture at surface
• Look for signs of over or under-watering
• Clean reservoir monthly

Troubleshooting Common Issues

Problem: Plants Are Wilting Despite Full Reservoir

Possible Causes: Clogged wick, air gaps, or root problems

Solutions:

• Check and clean the wicking system
• Ensure proper soil contact with wick
• Water from top initially to prime the system
• Verify soil isn’t too compacted

Problem: Fungus Gnats or Root Rot

Possible Causes: Too much moisture, poor drainage, or stagnant water

Solutions:

• Empty and clean reservoir thoroughly
• Improve air circulation around plants
• Use well-draining potting mix
• Add perlite or vermiculite to soil

Problem: Water Drains Too Quickly

Possible Causes: Drainage hole issues or soil problems

Solutions:

• Check for proper drainage plug installation
• Ensure soil mix retains adequate moisture
• Verify reservoir isn’t cracked
• Adjust soil composition if needed

Problem: Poor Plant Growth

Possible Causes: Nutrient deficiency, wrong plant choice, or environmental factors

Solutions:

• Add liquid fertilizer to reservoir (diluted)
• Ensure adequate light conditions
• Verify plant is suitable for self-watering
• Check temperature and humidity levels

Frequently Asked Questions

Do self watering planters actually work?

Yes, self watering planters are highly effective for most plants. They work by using capillary action to deliver water directly to plant roots as needed. Studies show they can reduce watering frequency by up to 75% while maintaining healthier plant growth. They’re particularly effective for vegetables, herbs, and most houseplants that prefer consistent moisture.

How often do I need to refill the water reservoir?

Most self watering planters need refilling every 1-2 weeks, depending on plant size, environmental conditions, and reservoir capacity. Larger plants and warmer conditions require more frequent refills. Always check the water level indicator and refill when it shows low rather than waiting for it to empty completely.

Can I use self watering planters for tomatoes and vegetables?

Absolutely! Tomatoes and many vegetables thrive in self watering systems. Tomatoes especially benefit from consistent moisture, which prevents blossom end rot and cracking. Other vegetables like peppers, lettuce, and spinach also perform excellently in these systems. Just ensure you choose planters large enough for root development.

Are glass self watering planters better than plastic ones?

Glass planters offer several advantages including better visibility of water levels and root development, no chemical leaching, and attractive aesthetics. However, plastic planters are more durable, lightweight, and often more affordable. Glass is excellent for indoor use and propagation, while plastic is better for outdoor and balcony applications.

What plants should I avoid in self watering planters?

Avoid plants that prefer dry conditions like cacti, succulents, and some Mediterranean herbs like rosemary and thyme. These plants are adapted to drought conditions and can suffer from root rot in consistently moist environments. Also avoid plants that need specific wet-dry cycles for flowering or dormancy.

How do I prevent algae growth in the water reservoir?

Prevent algae by keeping the reservoir covered and away from direct sunlight. Use opaque containers when possible, and clean the reservoir monthly with a mild bleach solution. You can also add a small amount of hydrogen peroxide to the water (1 teaspoon per gallon) to prevent algae growth without harming plants.

Can I use hanging self watering planters on walls?

Yes, hanging and wall-mounted self watering planters are excellent for vertical gardening. They’re perfect for small spaces, balconies, and creating living walls. Just ensure proper mounting hardware is used as these planters become heavier when filled with water and soil. Check weight ratings and use appropriate anchors for your wall type.
