Practical Tips for Growing Plants in Metal Planters

  • Watering Frequency

During summer, it’s crucial to monitor the watering needs of your plants. Metal planters can heat up, causing soil to dry out faster. Water your plants early in the morning or late in the evening to reduce evaporation. Make sure the soil is moist but not waterlogged.


Use a moisture meter to check soil moisture levels regularly. This tool can help you determine when your plants need watering, preventing both under and over-watering.

  • Using Shade Cloth

Protect your plants from intense afternoon sun by using a shade cloth. This can help reduce the temperature inside the planter and prevent the plants from getting sunburned.


Position the shade cloth to provide coverage during the hottest part of the day, usually between 11 AM and 3 PM.

  • Placing Away from Direct Sunlight

While many plants need sunlight, too much direct sunlight can be harmful, especially in metal planters. Place your planters in a spot where they receive morning sunlight but are shaded during the hottest part of the day. 


If you notice your plants wilting or showing signs of sunburn, consider relocating them to a less sunny spot or using garden umbrellas for temporary shade. 

  • Mulching

Add a layer of mulch on top of the soil to help retain moisture and keep the soil temperature stable. Organic mulch, such as bark or straw, works well and adds a decorative touch to your planters.


Keep the mulch away from the plant stems to prevent rot and ensure good air circulation.

  • Monitoring and Adjusting Soil

Metal planters can sometimes cause the soil to heat up quickly. Regularly check the soil temperature and, if necessary, add organic material or perlite to improve soil aeration and cooling.


Use a soil thermometer to monitor the temperature. The ideal soil temperature for most plants is between 65-75°F (18-24°C).

  • Regular Fertilization

Summer growth spurts mean your plants will need more nutrients. Use a balanced, slow-release fertilizer to provide steady nourishment.


Follow the manufacturer’s instructions on fertilizer application to avoid over-fertilizing, which can harm your plants.
