Steps
Pick a plant that roots easily for your first tries. Roses, willows and many shrubs root well from cuttings, while some species are slow and fussy.
Take cuttings from healthy, firm stems, not soft new growth or old woody canes. Cut a stem about 15 to 20 cm long with several leaf nodes.
Make a clean cut just below a node with sharp, clean pruners. A ragged cut gives rot an easy way in, so wipe the blades with rubbing alcohol first.
Strip the lower leaves so only one or two remain at the top. This cuts water loss while the cutting has no roots to drink.
Fill a pot with free-draining mix and water it before you plant. Push the cutting in so at least two nodes sit below the surface.
Cover the pot with a clear bag or dome to hold humidity, but leave a small gap for air. Too much trapped moisture is a common cause of rot.
Keep the pot in bright, indirect light at around 18 to 24 C. Direct sun can cook a bagged cutting, and deep shade slows rooting.
Check moisture every few days and mist lightly if the mix dries. Remove any cutting that turns black or mushy so it does not spread rot.
Tug gently after four to eight weeks. A cutting that holds firm has roots, so you can move it to a larger pot and start hardening it off.
Tips and common mistakes
Most failures come from the growing environment, not the cut, so fix humidity and light before blaming your technique.
Cuttings that rot from the bottom up usually sat in wet, airless mix, so use a coarse mix and never let the pot stand in water.
Cuttings that dry from the top down need more humidity, so check that your cover is sealed and the leaves are not in direct sun.
Start with easy plants and simple methods before trying difficult species, and label each pot with the plant name and date.
Questions
Why do my cuttings turn black and mushy?
That is rot, usually from mix that stays too wet or from a dirty cut. Use a free-draining mix, clean tools and a cover with a little airflow.
How long until rose cuttings root?
Most take four to eight weeks in warm conditions. Test by tugging gently rather than pulling the cutting out to look.
Do I need rooting hormone?
Not always. It can help on slower plants, but clean cuts, good humidity and the right temperature matter more.
