Propagation methods
P. indicus may be propagated by seed, which germinate in 8-100 days, but the initial growth of seedlings and saplings is relatively slow. Propagation by cuttings is preferred, especially for ornamental planting. P. indicus is unique among big timber trees in that the capacity for rooting of stem cuttings is not lost with age. Stem cuttings can be taken from trees of any age and size. Cuttings of diameter 6 cm or larger will root better than cuttings of smaller diameter. Young leaf-bearing stems will not root at all. For roadside planting, the cuttings used are in the form of stakes 15-3 m long and as much as 10 cm diameter. Such stakes produce up to 10 radiating shoots at the top, making a symmetrical crown very quickly, above pedestrian height. Few species can match P. indicus in the ability to produce well-crowned instant trees within one or two years. If large stakes fail to root, it is usually because of water-logging or accidental movement of the stakes during the tender rooting period. These problems can be avoided by rooting the stakes in loamy soil in large well-drained containers, while tied securely to a simple supporting framework. The stakes root in about 3 months and can be reduced to as short as 10 cm length, but such cuttings would take longer to develop into trees.

Thanks Seaburngirl, I think whoever looks after the gardens at the local hospital grounds may notice me taking 2 meter long 60cm branches, I will see how I go.

Ah yes. I just assumed you had your own tree to begin with. You could always ask the grounds man if they have the smaller 6cm wide prunings. obviously itll take longer but worth a try. good luck.

Again, my thanks, the 60cm was a typeo, I am use to dealing in mm's. I have buds coming on a 12mm cutting I took 2-3 weeks ago. I will keep you informed if roots take.

that makes sense Alan and actually the cm doesnt really exist as a scientific measurement anyway. I'm still happy day to day in ft/inches but have had to use SI units at work.

Buds sounds promising but dont be tempted to tip pot out to see if you have roots will you. I learnt the hard way many years ago. :o) I will be interested to see how you get on.

Update. We have roots on the 12mm hardwood cutting, leaves with I believe roots to come out the bottom of the 8 inch pot with cuttings as small as 6mm and even some sucess with leaf-bearing stems. Have heaps of shoots coming on the 250 + cuttings taken with 20mm Dia being the bigest.

Thanks for your help Seaburngirl, Success has been achieved.

thats brill news Alan. well done you. :o)
