Common problems with the Magenta Triostar

Yellowing or pale leaves - overwatering or insufficient light

  • Symptom - leaves that are an off-white or pale yellow

  • Cause - the soil has been drenched or waterlogged

  • Remedy - aerate the soil, or simply hold off until the plant dries out a bit until the next watering. If it is very damaged, you may need to repot.

Yellowing, browning and/or crispy edges - underwatering

  • Symptom - edges that turn brown or yellow with a crispy touch to them

  • Cause - underwatered

  • Remedy - remove the plant from its decorative pot and give a good shower in the sink, allowing it to sit in a dish of water for a few hours before draining and returning to pot. These cosmetic damages won’t go away, but you can prevent them from happening more.

Withered and/or brown leaves - air is too dry

  • Symptom - wrinkly, withered leaves that may have some brown edges

  • Cause - the air is too dry

  • Remedy - regularly mist the Magenta Triostar to boost moisture levels. Also, make sure your plant is not too close to a heater or air conditioner.

How to maintain a beautiful and healthy Magenta Triostar

Take care of your Magenta Triostar and it will take care of you! Below are simple tips to continue caring for and growing your Magenta Triostar over time.

  • Pruning - remove unattractive or damaged leaves from the base of the plant with a clean blade. Never remove more than 30% of the plant at a time.

  • Trimming - if there is just a small portion of a leaf that was damaged such as the edges, trim off any discoloration or blemishes by following the natural lines and shape of the leaf.

  • Cleaning - regularly remove dust to ensure your plant can soak in as much light as possible. Use a damp cloth and gently wipe the leaf clean while supporting the under side with your other hand.

How to grow and repot the Magenta Triostar

  • Growing - in prime conditions, Magenta Triostars are fast growers, unfurling new leaves from the center base. After some time, if you don’t see any new growth, consider adjusting one of its elements. During spring and summer, use a diluted fertilizer to give your plant a vitamin boost.

  • Repotting - L&G Magenta Triostars come in 6” grow pots and only need to be repotted every few years if you notice the roots outgrowing the pot, or to refresh the soil and give it new nutrients. If you’d like your plant to grow larger, find a new grow pot that is 2” larger than its current pot. If you’re happy with the current size, you can reuse the same pot and simply change the soil.

    • Getting your hands dirty with or without a yard - spread out newspaper on the floor, remove the plant from the pot and shake off as much of the old soil as possible so that you have clean roots. At the bottom of the grow pot, and a layer of soil, then place the plant in the center of the pot and cover with new soil. Pat down firmly and water thoroughly. Place the plant in an area with bright indirect light. Your plant will take 2-4 weeks to settle from the shock and adjust to its new home.

How to propagate the Magenta Triostar

Propagating a Magenta Triostar plant is best done through division and during spring or summer.

  • Divide the roots - remove the plant from its container and determine which area you will divide to create new plants. Make sure there is at least one bud in each clump of tubers, aka their roots. Carefully untangle the roots and pull apart with your hands or cut through with a clean sharp knife.

  • Place in fresh soil - Place the new divisions in fresh soil, press soil firmly and water thoroughly.

  • Stabilize - Keep freshly repotted plants in a warm area with bright indirect light, and for Magenta Triostars the soil should be kept moist thought not drenched.
