The soil for your Calathea Triostar should drain well but also keep some wetness.

Feeding your Calathea Triostar is an important part of Calathea Triostar Care because it gives the plant the food it needs to grow and keep its leaves looking amazing. Here are some fertilizing tricks for your Calathea Triostar:

  1. Frequency: Feed your Calathea Triostar every 4-6 weeks during the growing period, usually from spring to early fall. Don’t feed during winter because the plant’s growth slows down.
  2. Plant Food: Use a balanced, mix-with-water plant food that’s high in nitrogen, phosphorus, and potassium. Your Calathea Triostar likes plant food with a 3-1-2 or 3-2-1 N-P-K mix.
  3. Watering Down: Before feeding your plant, water down the plant food to half the suggested amount. This helps stop the plant food from burning, which can harm your plant’s roots and leaves.
  4. Application: Sprinkle the watered-down plant food around the plant, being careful not to get it on the leaves or stem. Water the plant after feeding to help the plant food spread around evenly in the soil.
  5. Other Options: To give your Calathea Triostar nutrients, you can also use natural plant food like fish emulsion, worm poop, or compost tea.

When feeding your plant, always follow the maker’s how-to and don’t give too much plant food because it can harm the plant. Your Calathea Triostar will keep growing and being happy with the right feeding and care, showing off its gorgeous leaves for many years!

Repotting a Calathea Triostar is pretty straightforward, and you gotta do it every 1-2 years when you spot the roots starting to poke out from the pot’s bottom. Make sure to use soil that drains well when repotting, ’cause the Calathea Triostar digs moist but not super wet conditions.

You can get to the repotting either in spring or early summer. When shifting the plant from one pot to another, handle it with care to avoid hurting the roots. Best time to repot is when the soil has dried up a bit. If the soil feels damp, let it dry a bit more before you go ahead with repotting.

Trimming is super important for taking care of your Calathea Triostar ’cause it helps to boost healthy growth, make it look good, and prevent diseases. Here are some tips on how to trim your Calathea Triostar:

Calathea Triostar Care Common Pests & Common Problems

Common Pests

Usual bugs bugging Calathea Triostar include spider mites and aphids.

  • Spider mites are tiny eight-legged creepers that munch on plant juice. They can cause yellow spots or speckles on the leaves, as well as webs between the stems.
  • Aphids are squishy-bodied bugs that munch on plant juice too. They can make leaves turn yellow, stunt the plant’s growth, twist leaves into weird shapes, or leave sticky, sweet goo on the surface of the leaves.

The best way to deal with these bugs is by getting them off physically with a cotton bud dipped in isopropyl alcohol. You can keep them in check with a spritz of neem oil or a splash of gentle garden soap.

If the bug party gets too wild, bug sprays or mite killers might be needed. It’s crucial to treat only affected plants and take the right safety steps when using any type of bug spray.

Common Problems

Like any other indoor plant, it needs the right care and attention to thrive. Here are some of the most common issues that might pop up when caring for Calathea Triostar:

  • Leaves curling up: This means the plant isn’t getting enough moisture. Increase the humidity around the plant by misting the leaves or using a humidifier regularly.
  • Leaf tips turning brown can indicate not enough moisture or too much fertilizer. To dodge this issue, mist the leaves often and don’t overdo it with the fertilizer.
  • Leaves turning yellow can be caused by giving too much or too little water. Water your plant only when the top layer of soil feels dry, and keep the right drainage in place to avoid waterlogged roots.
  • Leaf damage: Calathea Triostar can’t stand harsh sunlight, which can lead to leaf damage or scorching. Keep the plant in a shady spot away from direct sun.
  • Roots rotting is a fungus problem caused by giving too much water or lousy drainage that makes the roots rot away. To dodge this issue, keep the soil well-draining and only water the plant when the topsoil is dry.

If you love plants with cool patterns and gorgeous colors, then a Calathea Triostar is the perfect plant for you! With the right care, your Calathea Triostar will thrive and add life to any room in your home.
