About Gryphon, Begonia Seed, Begonia Seed

Gryphon Begonia is a striking foliage plant known for its large, deeply lobed leaves that feature a silvery-green color with dark green margins and veins, creating a bold, tropical look. It typically grows up to 12–18 inches tall and wide, making it ideal for containers, shaded garden beds, or as a houseplant. Gryphon Begonia thrives best in bright, indirect light or partial shade and prefers well-draining soil kept evenly moist but not soggy. For optimal care, avoid direct sun, provide moderate humidity, and feed monthly during the growing season with a balanced fertilizer.

Before Planting

For begonias, sanitize trays and fill them with a fine, sterile seed-starting mix. Arrange bright filtered light, bottom warmth, and a clear humidity cover before sowing the extremely small, light-requiring seed.

Planting

Start begonia indoors 12–16 weeks before the last spring frost. Surface-sow the extremely fine, light-requiring seed on a sterile medium, maintain 70–75°F, and keep humidity high without saturating the mix. Provide bright light immediately after emergence. Thin or transplant tiny seedlings once they can be handled, then harden gradually before moving outdoors after frost.

Watering

Bottom-water or mist gently so seed and young roots are not displaced. Keep humidity high only until germination, then ventilate gradually; mature plants like even moisture but suffer in saturated mix.

Fertilizer

Begin quarter-strength soluble fertilizer after seedlings have several true leaves. Increase gradually during active growth, using a balanced feed; rinse salts from containers and stop feeding dormant tuberous types.

Harvesting

Begonias are usually enjoyed on the plant rather than harvested. For floating or short-stem displays, take freshly opened, unblemished flowers during cool conditions. Remove faded blooms at the base. Collect seed only from completely dry capsules, handling carefully because the seed is dustlike.

Tips

Pelleted seed is easier to space. Delay transplanting until seedlings are large enough to handle by their leaves, acclimate them slowly to lower humidity, and protect all begonias from frost and harsh midday sun.

Pests & Diseases

Begonias are prone to Botrytis blight, powdery mildew, bacterial leaf spot, and Pythium or Rhizoctonia root rot. Gray mold, white coating, water-soaked spots, or blackened roots often follow crowding and excess moisture. Start with clean media, keep leaves dry, improve airflow, sanitize tools, isolate affected plants, and discard severely rotted specimens.

Thrips scar begonia flowers, spider mites stipple leaves, vine-weevil larvae damage container roots, and slugs chew outdoor plants. Inspect flowers and leaf undersides, quarantine new plants, and check roots when an otherwise moist plant wilts. Handpick slugs and adult weevils after dark.
