Quick Tips to Propagate Hydrangeas
- Take cuttings from a healthy plant (non-flowering stem)
- Use clean tools to avoid infections
- Choose a moist and warm location
- Use rooting hormone (optional but helpful)
- Be patient – rooting takes 2 to 4 weeks
How to Propagate Hydrangeas from Cuttings
This is the most common and successful method to grow new hydrangeas. I’ve done this many times and most cuttings root very well if kept in the right condition.
Step-by-Step Process
1. Choose the Right Cutting:
- Select a healthy green stem (non-flowering)
- It should be about 4 to 6 inches long
- Make sure it has 2-3 leaf nodes
2. Prepare the Cutting:
- Use a sharp knife or scissor
- Cut just below the leaf node
- Remove the lower leaves, keep only top 2 leaves
- Optional: Dip the cut end in rooting hormone
3. Prepare the Soil:
- Use a mix of cocopeat and garden soil
- Make the soil moist, not soggy
4. Plant the Cutting:
- Insert the cutting about 2 inches deep
- Press the soil gently around it
5. Provide the Right Environment:
- Cover the pot with a plastic bag to maintain humidity
- Keep it in bright indirect light
- Water lightly every 2–3 days
6. Rooting Time:
- Roots develop in about 3–4 weeks
- After that, you can transplant to a bigger pot
My Tip: I always keep the cuttings in a shaded area with good air flow. Avoid direct sun or windy spots.
How to Propagate Hydrangeas in Water
Water propagation is my personal favorite method. It’s easy, clean, and you can see the roots growing day by day.
Step-by-Step Process
1. Take the Cutting:
- Same as soil method, use a 4–6 inch stem
- Remove lower leaves and keep 2 leaves at top
2. Place in Water:
- Use a clean glass jar or bottle
- Fill with filtered or boiled-cooled water
- Make sure the leaf node is underwater
3. Change Water Regularly:
- Change water every 3–4 days
- Clean the jar if it gets dirty
4. Root Growth:
- Roots appear in 2–3 weeks
- Wait until roots are 2 inches long
5. Transplant into Soil:
- After rooting, gently move the cutting to moist soil
- Keep in indirect sunlight for 1 week before full sun
My Tip: Always keep the jar in a bright spot but away from direct heat. I place it near a window with light curtain.
How to Propagate Hydrangeas in Pot with Plastic Cover
This method is a variation of soil method, but the twist is – you cover the entire pot to create a mini greenhouse. I tried this method during monsoon and got excellent results.
Steps to Follow
1. Prepare Potting Mix:
- Use light soil mix – cocopeat + compost + perlite
- Make sure it is moist but not wet
2. Insert the Cutting:
- Same type of cutting – 4–6 inch, green, no flower
- Insert into moist soil
3. Cover the Pot:
- Use a transparent plastic bag
- Make small holes in it for air exchange
- Tie it around the pot so it stays humid inside
4. Placement and Care:
- Keep in indirect light
- Do not water often – the humidity stays inside
- Open the cover once in 2 days to check moisture
5. Rooting and Growth:
- Roots develop within 3 weeks
- After rooting, slowly open the bag for a few hours daily
- Then remove the cover fully after 1 week
My Tip: I used this method during rainy season when humidity is already high. The cuttings didn’t dry out and rooted very fast.
Aftercare Tips for Propagated Hydrangeas
Once your hydrangea cuttings have rooted and been planted, follow these simple care tips:
- Water regularly but avoid overwatering
- Keep in indirect light for 1–2 weeks after transplant
- Use liquid fertilizer once a month
- Trim the plant to promote bushy growth
- Protect from direct sun and wind in the beginning
