String of Pearls Care & Growing Guide

1. Light Requirement

The String of Pearls grows best in bright light, including sunlight.  It does best when it in is or near a window that faces south or west.  If you have limited natural light, you can use a fluorescent light.  Put the plant 6 to 12 inches under the light for 12 to 16 hours each day.

2. Water

One important thing to remember when watering your String of Pearls plant is that in a pot with no drainage holes make sure that you do not overwater it.  This is a plant that does not need to be watered frequently.  The leaves retain moisture quite well.  

You will only need to water them one or two times a month.  In the winter, watering should be reduced to once a month, because during the winter they are not actively growing and do not need as much water.  Before watering, let the soil become dry.

3. Climate

This plant does best in hardiness zones 9 to 12.

4. Soil

The best soil in which to plant your String of Pearls is a well-draining succulent or cactus potting mix.  This type of soil is different from your houseplant soil.  This potting mix will facilitate drainage faster because of the sand and perlite that is added to the mixture.  This type of plant must have plenty of drainage through the drainage hole at the bottom of the pot.

Common String of Pearls Plant Diseases

The String of Pearls is prone to several diseases, including:

  • Root rot—this can happen if you water them too frequently.
  • Pests—generally they are not vulnerable to pests but can sometimes be infested with aphids, fungus, and mealy bugs.  You can use a cotton ball dipped in 70% rubbing alcohol and rub it on the leaves.

Conclusion

  • If you have a pot with no drainage holes, add a layer of perlite or small pebbles in the bottom of the pot before putting in the potting mixture.  This layer of drainage will keep the roots from sitting in wet soil.
  • Remember to water them as directed because if you wait too long to water them, it can affect the leaves.  The leaves can wilt or shrivel/flatten if the soil becomes too dry.  Good watering can revive the plant as long as it has not been too dry for too long.
  • They do not need to be fertilized but during the active growing season, which is spring/summer, you can use a houseplant fertilizer that has been diluted.
  • If you want them to appear fuller, stick the ends of the stems back into the soil so it makes a little loop.
  • To propagate String of Pearls, take three to four-inch stem tip cuttings, making sure to remove any leaves from the bottom and put in the potting mixture.
  • To help encourage flowering in the spring, move the plant to a cooler area of the house during the winter months.  The best temperature for this process is around 60 degrees Fahrenheit.
  • Do not let the String of Pearls grow long enough to touch the floor, especially if you have children or pets because they are very toxic if ingested.  Keep them out of reach of children and pets.
