For those with brugmansias, here is an easy way to increase your stock.
Any large plants outside, now look a bit sad. If you cut them down like a buddleja, it reduces the size of the plant to overwinter(frost free) The bits you cut off make cuttings which will root over the winter, stood in a jar of water in a windowsill.
This is a three year old plant which has been in the flower bed all summer. The root spread mean it is not feasible to lift it, so I cut it down and let the frost have it.
Last years cuttings, potted into 6 inch pots in march, have flowered and provide ideal cutting material.
Cut down to overwinter in greenhouse.
Cuttings trimmed up from the prunings.
Coffee jars filled with water, and the cuttings stand in these on a windowsill for the winter. They will develop white nodules below the water line, from which roots will grow. The water may need to be topped up from time to time. In March, I pot the rooted cuttings into 6 inch pots.
Cutting ready for next size pot.
Potted into 15 inch pot in May. Feed and water well for it to flower well in the summer. At the end of first year, cut down and make new cuttings.
