When to plant
Plant begonias in spring, once the danger of frost has passed and daytime temperatures reach around 15 °C or higher. In mild climates, tubers may also be planted in late winter with protection.
Where to plant
Choose a spot with filtered light, partial shade, or bright indirect light. Begonias dislike full scorching sun, which can scorch leaves. Whether in garden beds, containers, or indoors, ensure good airflow and avoid damp, stagnant sites.
Preparing the soil
Use a light, well-draining mix rich in organic matter. Loosen the soil to about 15–20 cm and enrich with compost or peat to improve moisture retention without waterlogging. If your soil is heavy, add perlite or coarse sand to improve drainage.
Planting the tubers / rhizomes / plants
For tuberous types: place the tuber horizontally, covering it with about 2–4 cm of soil, leaving the “neck” or growth point just below the surface. For rhizomatous types: set the rhizome right at soil level, lightly covered. Plant with spacing of 20–30 cm in beds, or closer in containers for a full effect.
After planting
Water gently to settle the soil around the planting. Keep the soil evenly moist—not soggy—especially while the plant establishes itself. Avoid overwatering, which invites rot.
During growth & blooming
As leaves and flowers emerge, maintain moderate moisture and avoid waterlogging. Fertilize lightly with a balanced fertilizer every few weeks during active growth. Remove spent flowers to encourage further blooms and prevent pests.
After flowering / end of season
Let the plant rest if growth slows. In colder climates, lift tubers after foliage dies back, gently clean them, and store them in a cool, dry place for the next season. For rhizomatous or cane types, protect them from frost with mulch or move containers inside. Trim away dead foliage to maintain plant health.
Extra tips
Begonias thrive with humidity—mist leaves or use pebble trays (without soaking roots). Provide filtered light rather than direct sun. Avoid watering overhead, especially on variegated or delicate leaves. Rotate containers for even growth. If pests or mildew occur, prune affected parts and improve airflow. With correct care, begonias reward gardeners with long-lasting blooms and foliage beauty.
