  • Light: Bright indoor light is necessary for this plant to thrive. Too little light can lead to necrotic leaf patches and ultimately leaf loss.

    Temperature: 65-85 F

    Humidity: medium; avoid drafty areas

  • Water: Keep the potting mix moist but not soggy. Water when the top 1-2” of mix dries. Check moisture 1-2 times/week as begonias hate to dry down completely.

    Repotting: Repot every 2-3 years into a slightly larger container (1-2” increased diameter or depth). Use a general purpose potting mix.

    Fertilizing: Either…

    1. Water Application: Incorporate fertilizer into your watering cycle once per month March through September. Dilute an all purpose fertilizer (20-20-20) by half OR use your favorite fertilizer rated for houseplant use in your water.

    2. Slow Release: Incorporate slow release fertilizer pellets into the top inch of potting soil every 6 months. Apply the rate indicated for indoor plants on the label. If no recommendation for houseplants is present, apply 1/4 to 1/2 the listed rate.

  • The Begoniaceae family is quite large, claiming only two genera, but over 2000 species! There are MANY types of begonias out there in the wild to be enjoyed.

  • (Listed in order of commonality…)

    • Necrotic leaf spotting and leaf drop caused by low light levels

    • Root decay caused by soggy potting mix

    • Fungus gnats

    • Mealybugs

  • Begonias are often grouped by their growth habit—rhizomatous (horizontal stem) and cane (vertical stem). Begonia rex-cultorum and Begonia maculata are two popular rhizomatous and cane type begonias respectively.
