Double Begonias are native to South and Central America, Africa, and southern Asia, liking the moist climate of a sub-tropical or tropical environment. This means that although the begonia is a simple plant to care for, choosing the right location and watering them properly (moist soil, but not too wet) is essential to success. Double Begonias have bronze or green foliage, and the double-flowered rosette blooms typically come in whites, reds, and pinks. Begonias grow well in containers.
General Growing Tips For Your Rooted Cutting Liner
For best results with Double Assorted, we recommend using a constant feed program of 200 ppm N. Maintain a pH between 5.5 - 6.2. Allow soil to dry slightly between watering.
Pinching
We recommend that you pinch Double Assorted 5-10 days after transplanting to your final container. Additional pinches every couple of weeks may be required to shape your final pot. Remember to give your double begonias 4 weeks from their final pinch to reach bloom stage.
Spacing
Begonias should be spaced adequately to allow airflow and light penetration between the foliage. Usually 2’ centers on baskets will be enough.
Height Control
In our experience, plant growth regulators will stop growth completely in double begonias (keeping them from ever growing again). Proper pinching is the best way to control height.
Pests
Aphids may be a possible pest problem with Begonias.
Disease
Double Assorted are not prone to many diseases, but watch for botrytis and plant rot while the days are short. Botrytis is a grey rot usually associated with wet or humid conditions. You can prevent it by allowing the plant to dry out between waterings, allowing for good airflow in your greenhouse, and spacing to allow the sun to penetrate to the soil level. The most common chemicals used to treat botrytis are Medallion and Banrot. Use them as a drench according to each label’s instructions.
Planting Double Assorted Liners
1. We recommend planting 4 starter plants per 10 inch basket. Use a well-drained soil in your baskets and plant your starter plants deep, allowing the ellepot to be completely covered by the soil. If you are planting 4” pots, 1 plant per pot should be sufficient. Plant it directly in the middle of your pot.
2. Pinch Double Assorted 5-10 days after transplanting to your final container. Additional pinches every couple of weeks may be required to shape your final pot.
Rooted Cuttings
Cuttings vary in size between different plant families. These rooted starter plants will arrive ready to be transplanted in to your final container. If they are to be used in a landscape application, you will need to establish them in a 4 inch pot or an 1801 before planting outside.
