The cuttings I started about 2 months ago in Styrofoam boxes were ready to be moved into pots.
Apart from noticing new growth, the easiest way to tell when they're ready is to give them a little tug. Resistance means there are roots.
Cordylines produce root quickly. They are one of the easiest plants to propagate.
The shadehouse is starting to look quite full already and I still have lots more to pot up. Lucky I've saved lots of old pots.
Now that the weather is starting to cool down, cuttings will not strike as readily, so I'll be moving my efforts to different methods of propagation - division of roots and clumping plants. Gingers, cannas and heliconias will grow from a piece of root. Liriope, spiderlily, mondo grass and rhoeo (Tradescantia spathacea) divide easily to make new plants.
The greenhouse will be overflowing by the time I finish.
