Setup and Installation
Follow these steps to assemble and install your LaLaGreen planter boxes:
- Prepare the Inner Planter: Insert the water level indicator into the designated slot in the inner planter. Ensure it is securely in place.
- Insert Inner Planter: Place the assembled inner planter into the outer planter box.
- Drainage Plug (Outdoor Use): For outdoor use, locate the drainage hole at the bottom of the outer planter. Remove the rubber plug to allow excess water to drain, preventing root rot. Keep the plug in for indoor use to prevent water leakage.
- Assemble Brackets: The metal brackets are adjustable to accommodate different railing sizes. There are two ways to install the handles depending on the thickness of your rails:
- For thinner rails, screw the shorter portion of the handle into the bracket.
- For thick and wider rails, screw the longer portion of the handle into the bracket.
Additionally, an adjustable metal part needs to be screwed into the bottom of the bracket to ensure proper alignment and positioning of the planter on the railing. Adjust this part to match the gap needed for your specific railing.

- Attach Brackets to Planter: Securely attach the assembled brackets to the designated slots on the back of the outer planter box.
- Hang on Railing: Carefully hang the planter box onto your deck or fence railing. Make any necessary adjustments to the brackets to ensure a snug and stable fit.
- Add Plants and Water: Once the planter is securely in place, add your desired plants and soil to the inner planter. Then, fill the outer planter with water up to the optimum level indicated by the water level indicator.

Operating Instructions (Self-Watering System)
The LaLaGreen planter features an efficient self-watering system to keep your plants hydrated:
- Water Reservoir: The outer planter acts as a water reservoir. Water is drawn up to the plant roots in the inner planter as needed, through capillary action.
- Water Level Indicator: Monitor the water level using the integrated indicator. Fill water when the indicator reaches the 'minimum' mark. The 'optimum' level is recommended for regular watering, while 'maximum' indicates a full reservoir. The indicator also includes a 'fertilizer reminder' section.
- Watering Frequency: Depending on the plant type, climate, and size, watering may be required every 1-3 weeks. Regularly check the water level indicator.
- Outdoor Drainage: If using outdoors, ensure the drainage plug is removed from the bottom of the outer planter to prevent overwatering during rainfall.

A detailed inset displays the water level indicator, marking minimum, optimum, and maximum water levels, along with a fertilizer reminder. It also shows the drainage plug for outdoor use.
Maintenance
To keep your LaLaGreen planters in excellent condition:
- Cleaning: Periodically clean the planters with mild soap and water. The inner planter can be easily removed for thorough cleaning.
- Water Level Indicator: Ensure the water level indicator moves freely. If it becomes stiff, gently clean it to remove any mineral buildup.
- Bracket Inspection: Regularly check the metal brackets and screws for tightness, especially after heavy winds or if the planter is moved.
- Winter Care: In freezing climates, it is recommended to empty the water reservoir and bring the planters indoors or store them in a sheltered area to prevent damage from ice expansion.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Plants are wilting/dry | Low water level in reservoir | Refill the outer planter with water up to the optimum level. |
| Plants show signs of overwatering (yellowing leaves, soft stems) | Excess water, especially outdoors | Ensure the drainage plug is removed for outdoor use. Reduce watering frequency. |
| Planter is unstable on railing | Brackets not properly adjusted or tightened | Re-adjust the bracket handles and the bottom alignment piece to fit your railing snugly. Tighten all screws. |
| Water level indicator stuck | Mineral buildup or debris | Remove the inner planter and gently clean the indicator and its slot with water. |
