It is known for its compact mounted habit and tolerance of hot sunny conditions.The hardiest begonia, by far, is the tuberous Begonia grandis (USDA zones 6-10; Sunset zones 3-24) from China and Japan. Several clones are now in cultivation. The typical form has large round leaves with a pale green reverse, or with red veins, and pale pink or white flowers.Hardy begonia (Begonia grandis) can thrive as a perennial in USDA Hardiness Zones 6-9, returning each year. However, in Zones 5 and below, these plants struggle to survive outdoors with winter’s extremely cold temperatures. Ideal for shade gardens, hardy begonias grow into a 2-to-3-foot mound of lush, green leaves.
Do tuberous begonias need sun or shade?
Tuberous begonias should be grown in bright shade (too much sun will burn them and too little will make them leggy) and watered only when the soil dries out completely. We can easily love them to death,” Sanchez said. The biggest problem with tuberous begonias is operator error in the form of overwatering. If you are planting your begonias in a garden bed, make sure to choose a spot with the right amount of light and well-drained soil. If you are growing them in pots, use a high quality, humus-rich growing mix. Pots must have drainage holes on the bottom, so the roots can breathe, and excess water can drain away.To overwinter tuberous begonias, lift the tubers in autumn when the leaves start to yellow, remove the foliage, allow the tubers to dry, and store them in a cool, dry place over winter. Replant in spring after the risk of frost has passed.Top dress in ground-grown begonias once a month with a balanced (20-20-20) slow-release granular fertilizer once a month during their blooming period. Fertilize container-grown begonias every other week with a weak solution of a balanced liquid fertilizer.Habit and size: Tuberous begonias are tuberous perennials with a bushy or cascading growth habit, typically reaching around 12-18 inches (30-45 cm) in height and spread.
What month do you plant tuberous begonias?
Begonias are tender bulbs and require protection from frost. For best results, start them off in temporary pots in a greenhouse in March or April to give them a head start. They can then be transplanted outside in May. Begonia tubers can also be planted directly outside into borders or containers in May. One of the best ways to keep begonias happy and flowering is to plant them in well-draining soil. They also need the right amount of sunlight, moisture, and nutrition. Read the label on your plant to determine if it can handle full sun or shade conditions before choosing a spot to plant it.Coleus: Known for their striking, colorful foliage, coleus plants work well as companion plants for begonias, especially in containers or mixed borders. Both plants appreciate similar growing conditions.Soil: All begonias like evenly moist, well-draining soil with some added organic matter. For container-grown begonias, use a well-draining potting soil with added organic matter to help retain moisture without becoming soggy.Watering: How Often Should I Water My Begonias?

Which begonias come back every year?
Do begonias come back every year? Some begonias, such as hardy begonias (Begonia grandis) come back if grown within their hardiness range, in this case Zone 6-9. However, like other tuberous begonias, you may need to dig up the tubers and store them indoors to replant them the following spring. Unlike potato tubers, you can’t cut begonia tubers into pieces to produce more plants. Although some growers divide begonia tubers, they must make the divisions when the plant is actively growing, and the tuber pieces often become diseased and rotten.If roots grow against the edge of the pot, you may want to repot your plants to enable more growth. Watering correctly is very important to good results. The American Begonia Society says that some growers soak their tubers in water or a sterilizing solution before potting them, which helps initiate growth.Tuberous Begonias thrive in soil that is evenly moist but well drained. Soggy soil can cause the stems to snap off at the base. Fertilize plants once a month with a balanced (20-20-20), water-soluble fertilizer mixed as directed.Begonias make excellent container plants. They prefer to be slightly root bound rather than given room for their roots to sprawl. Let the soil dry out between watering and add a balanced liquid fertilizer every few weeks during the growing season.A: To encourage begonias to bloom, give them 3-4 hours of bright, indirect light and plant them in a well-draining soil mix. Regularly feed them with a balanced liquid fertilizer during the growing season. Water your plants consistently but ensure the soil doesn’t get soggy.
What is the lifespan of a begonia?
Generally, begonias grown as annuals will last for one growing season before dying off. However, some perennial begonia species can last for several years with proper care. Indoors, potted begonias can last for several years with the right environment, care, and maintenance. They prefer a rich, well-drained, neutral to slightly acidic soil. Most begonias dislike direct sun and will provide the richest color in your shadier—but not completely dark–corners.Begonias are perennial in frost-free regions and annual in colder climates unless they are brought indoors for the winter.The bedding plant fibrous begonias, Dragon Wing Begonias and Bonfire Begonias handle full sun best.
