Tips to Provide Optimum Light & Temperature

  • Rotate your plant occasionally to ensure all parts receive equal light throughout.
  • If you live in a darker apartment without enough sunlight, you can use fluorescent light to grow them.
  • Give your plant 10-12 hours of grow light during winter to ensure sufficient sunlight.
  • Use heating pads or frost blankets in winter to keep them warm.

2. Watering & Humidity

Peperomias don’t like sitting in the pool of water and will not thrive underwatering either.

Therefore, watering Mini Watermelon Peperomia will be efficient once the top inch of the soil dries out or once a week during spring or summer with a humidity of 40-50%.

3. Soil & Fertilization

Mini Watermelon Peperomias foliage will grow lusciously if provided with a good soil mixture.

Mini Watermelon Peperomia grows well in a standard potting mix that is well-draining, moisture-retaining, good air circulation, and has a pH of 6-6.6.

However, root burn, leggy, and spindly growth are the signs of over-fertilization.

On top of that, the plant shows symptoms like slower growth, pale yellow foliage, and a frail stem when it suffers from under-fertilization.

Tips to Provide Proper Soil & Fertilization

  • Thoroughly water before and after applying the fertilizer to your plant.

  • As a final treatment, apply malathion solutions or Neem oils to control the pest infestation.

5. Frequent Repotting 

Mini Watermelon Peperomia prefers repotting once every three years in a slightly larger pot than the current one during spring or summer.

Propagating the Mini Watermelon Peperomia by stem cutting is one of the simplest methods.

So, let us begin the propagation via stem cutting, shall we?

Step 1: Get the Cuttings

  • Identify and choose one of the healthy stems for propagating.
  • Ensure the selected stem has a healthy leaf on top of it.
  • Cut off the stems neatly at a 45° angle, leaving 2-3 inches of stem to stay right up when planted in soil.
  • Make sure there are no leaves on the bottom part but leave the top leaves.

Step 2: Rooting in Water

  • Place it in a glass or vase with a wide neck to easily transplant if needed.
  • Fill the container with clean water and submerge the cutting only halfway.
  • Use rooting hormone for better growth of the roots.
  • Change the water weekly or when it starts to get dirty.
  • Place the jar in a warm place with sufficient ample sunlight.
  • When the roots grow an inch, you can transfer them to the soil.

2. Propagation via Leaf Cuttings

You can use the broken leaves or cut healthy leaves straight from the plant. Use a seedling tray or rectangular water-filled container if you have many leaf pieces.

Follow the steps to propagate it easily.

  • Cut the leaf in half above the petiole with a clean cut using a sharp scissor.
  • Prepare potting soil consisting of compost, peat moss, and perlite.
  • Place the half leaf with the petiole in the soil, but it will also propagate if it is just above the soil.
  • Water the plant lightly or use a mister to avoid overwatering.
  • To create humidity and retain moisture, wrap the plant in plastic wrap or use a container with a lid.
  • Place it in a spot where it gets warm indirect sunlight.
  • Roots will form within 2-3 weeks.
  • Remove the lid or plastic wraps after roots start forming.
  • When the plants are big, place the plant in a regular pot without damaging the roots.
