Why is my Moss Rose not blooming?

Moss Rose needs specific conditions to produce its vibrant flowers. If your plant is green but lacks buds, it is likely missing out on the intense light it craves.

Check these first

  1. Check if the plant gets at least 6 hours of direct sun.
  2. Look for signs of stretching or leggy growth.
  3. Review your recent fertilizing schedule.

Likely causes

  1. Insufficient Light

    Most likely

    How to tell: The plant looks stretched out and has very few or no flower buds. It is likely sitting in a spot that gets partial shade.

    What to do: Move your plant to a location that receives full, direct sun for at least 6 to 8 hours a day. Moss Rose will not bloom well in the shade.

  2. Too Much Fertilizer

    Possible

    How to tell: The plant is very leafy and lush but produces no flowers. This often happens when the soil is too rich in nitrogen.

    What to do: Stop fertilizing for a few weeks to let the plant focus on blooming. If you must feed it, use a low nitrogen, high phosphorus fertilizer.
