Begonia 'Martha Stewart' is a strong grower. Although most rhizomatous begonias are grown for their interesting leaves, they also display clusters of small lovely blooms that grow like clouds above the foliage. The flowers range in color from blush to pink. And also white – so many of them are blooming right now.
Begonias dislike wet feet. Between waterings, let the soil dry out slightly. When the growing season begins in early spring, start feeding the plants with an organic 3-3-3 fertilizer. For the best results, place pots in a warm room with bright indirect light. For unusual varieties, go to Logee's and Glasshouse Works.
The plants themselves are manageable in size and can be housed in shallowish pots (just six to eight inches deep); they thrive in bright indirect sunlight.
Moderate feeders when grown under high light. Fertilize with fertilizer per gallon of water once a week during the summer or when actively growing.
For growing begonias indoors, use a soil-less mix – one that is mostly peat-moss based with additional perlite and/or vermiculite to improve aeration around the roots.
