How to Grow Rex Begonias


Joy Logee Martin always grew her Rexes in an east bay window and would only water them when they cried for water.


Growing Tips

• Place in good light; some direct sunlight is needed.

• Accurate watering – Bring plant to a slight wilt between waterings.

• Moderate fertilizer once a month.

• Stop fertilizer in the winter. 

• Keep humidity above 50%. 

• Keep night temperatures above 60-65ºF.

• Growth cycle slows and stops for 2-3 months in the winter.  Plants can lose some leaves during this resting period. This is normal.  Continue normal watering.

• Use terra cotta or clay pots.

• Keep an eye out for mildew to which Rexes have some susceptibility. 


Treating Mildew

• Identify - Appears as a white powder on the surface of the leaves, usually at the change of seasons.

• Treatment - Apply a baking soda solution -1Tbl/quart with a dribble of dishwashing detergent. 

• Application - Spray at first signs and reapply every other day for 4-5 applications.

• Prevention - Spray once every 3 months. 

**Pure Neem Oil is effective on mildew
