During the hottest months, you may need to water more frequently.
Be sure to provide good drainage, as these plants do not like to sit in soggy soil.
Fertilize every other week using a water-soluble fertilizer such as 20-20-20.
What Is The Best Soil For Iron Cross Begonia, And When Should You Transplant?
Iron Cross Begonia plants do best in soil rich in organic matter. You can mix your own soil or use a potting mix designed explicitly for begonias.
When transplanting your Iron Cross Begonia, be sure to do it in the early spring or late fall when the plant is not actively growing. This will help to prevent transplant shock.
When potting or repotting your Iron Cross Begonia, it is best to use a pot slightly larger than the one it is currently in.
This will help prevent the roots from becoming too crowded and make it easier to keep the soil moist.
Also, be sure to use a pot with drainage holes in the bottom to prevent root rot.
