QUICK ANSWER
Water propagation roots a stem cutting in 1 to 2 weeks and lets you watch the roots form before potting up.
Soil propagation skips the water-to-soil transition and roots in 2 to 3 weeks under high humidity, with stronger roots that handle repotting better. Division of a mature pot-bound clump gives you instant flowering plants in 1 to 2 weeks.

You'll need
Healthy patchouli stem with 3 to 5 leaf nodes
Sterile sharp scissors
Clear glass jar
Filtered water (or tap water left to sit 24 hours)
Bright indirect light
Small pot with potting mix for transplant
1
Take a 4 to 6 inch tip cutting
Cut a healthy non-flowering shoot just below a leaf node with sterile scissors. The cutting should have 3 to 5 leaf pairs. Take the cutting in the morning when the plant is fully turgid.
2
Strip the lower leaves
Remove leaves from the bottom 2 inches of the stem. Submerged leaves rot fast and foul the water. Leave the top 2 to 3 leaf pairs in place.
3
Place stem in water
Set the cutting in a clear jar with enough water to cover the stripped nodes. Place the jar in bright indirect light at 70 to 80 degrees Fahrenheit. Patchouli loves warmth and roots fastest in summer.
Change the water every 3 to 4 days or when it looks cloudy. Fresh water is the single biggest factor in preventing stem rot.

4
Watch for white roots at week 1
Tiny white roots emerge from the submerged nodes within 5 to 10 days. Wait until roots reach 1 to 2 inches before potting up. Patchouli roots grow fast once they start.
5
Pot up in moist potting mix
Move the rooted cutting into a 4 inch pot of regular potting mix. Water immediately and keep the mix consistently moist for the first 2 weeks while the water roots adapt to soil.
WATCH FOR
The submerged stem turning brown or mushy. That is stem rot, usually from water that was not changed often enough or a contaminated jar. Re-cut half an inch above the damage with sterile scissors, rinse the jar, and start over with fresh water. Patchouli recovers well from a single re-cut as long as you catch the rot early.

You'll need
Healthy patchouli stem with 3 to 5 leaf nodes
Sterile sharp scissors
Rooting hormone (optional)
4 inch pot with drainage holes
Light potting mix or 50/50 potting mix-perlite
Clear plastic bag or dome
1
Take a 4 to 6 inch tip cutting
Cut a non-flowering shoot just below a node. The cutting should have 3 to 5 leaf pairs. Strip leaves from the bottom 2 inches of stem.
2
Dip the base in rooting hormone (optional)
Patchouli roots without hormone, but a quick dip pushes success from 80 to nearly 100 percent and shaves a few days off the timeline. Tap off excess powder.
3
Stick the cutting into moist mix
Push the cutting 1.5 inches into pre-moistened light potting mix. Firm the soil around the stem. Water gently to settle the mix.
Patchouli rots in heavy waterlogged soil but stalls in bone-dry mix. Aim for evenly damp like a wrung-out sponge.

4
Cover with a humidity dome
Tent the pot with a clear plastic bag held off the leaves with sticks, or use a clear dome. Keep at 70 to 80 degrees Fahrenheit in bright indirect light. Mist the inside of the dome once a day.
5
Vent the dome at week 2
Open the dome for 1 hour the first day, doubling daily for a week. By the end of week 3, give a gentle tug. Resistance and small new leaf growth at the tip mean the cutting has rooted.
6
Care for the rooted cutting normally
Once the cutting is rooted and the dome is fully off, treat the new plant like any other patchouli. Bright indirect light, evenly moist soil, and a balanced fertilizer at half strength once a month.
WATCH FOR
Wilting that does not recover overnight after a watering. That usually means the cutting rotted at the base before roots formed. Lift it gently, examine the buried portion, and re-cut above any black tissue with sterile scissors. Restart in fresh mix with a fresh hormone dip. Yellow leaf drop without stem blackening usually means low humidity, mist the dome more often.

You'll need
Mature patchouli with multiple stems sharing a root mass
Sterile sharp knife or pruners
Two 6 inch pots with drainage holes
Fresh potting mix
Bucket of water
Bright shade for first week
1
Water the parent plant the day before
A well-hydrated root ball separates more cleanly than a dry one. Soak the pot deeply 24 hours before dividing. The soil should be moist but not muddy on the day of.
2
Unpot and tease apart the root ball
Tip the pot sideways and ease the plant out. Brush off enough soil to see where individual stems connect to their own roots. Patchouli usually has several distinct shoots, each with its own fibrous root system.
3
Cut the divisions
Use sterile pruners or a sharp knife to slice between the shoots, giving each division at least one strong stem and a portion of the fibrous root mass.
Each division should have enough roots to support its top growth. If a division has under 3 inches of root, it usually struggles.

4
Pot up each division
Settle each division into a 6 inch pot of fresh potting mix at the same depth it was growing before. Press the soil firmly around the roots. Water in deeply.
5
Recover in bright shade
Place the new pots in bright shade for 7 days. The divisions wilt slightly the first day or two, that is normal. New leaf growth at the tips by week 2 means each division has settled in.
WATCH FOR
Whole stems wilting and not recovering after a deep watering. That signals the division was too small for its top growth. Cut each affected stem back by half and shade the pot for another week. Patchouli regrows quickly from cut-back stems as long as the root mass is alive.
