How to take basal cuttings of delphiniums in March
Taking basal cuttings of delphiniums in March is one of the most reliable ways to produce strong, true-to-type plants. It allows you to clone your best plants and maintain flower colour and quality year after year.
Early spring is the ideal time, as fresh new shoots emerge from the base of the plant.
Quick answer: how to take delphinium basal cuttings
To take basal cuttings from delphiniums, select young shoots from the base, cut them cleanly with a small piece of stem, and place them in free-draining compost. Keep moist, in bright indirect light, and allow them to root before potting on.
Step-by-step guide to taking delphinium basal cuttings
Step 1: Identify suitable shoots
- Choose young shoots (5–10cm tall)
- Take from the base of the plant
- Avoid hollow or flowering stems
Step 2: Take the cutting
- Use a sharp, clean knife
- Cut close to the crown
- Include a small piece of solid stem tissue
Step 3: Prepare the cutting
- Remove lower leaves
- Dip the base in rooting hormone (optional)
- Keep cuttings cool and fresh
Step 4: Plant in compost
- Use a free-draining mix (compost with grit or perlite)
- Insert cuttings around the edge of a pot
- Firm gently
Step 5: Create the right environment
- Water lightly after planting
- Cover with a propagator lid or plastic bag
- Keep in bright, indirect light
When to take delphinium cuttings
Basal cuttings should be taken:
- In March to early April
- When new growth is actively emerging
- Before plants begin rapid vertical growth
This is when shoots are strongest and most likely to root.
Best delphiniums for cuttings
- Pacific hybrids
- Tall, dramatic flower spikes
- Popular in borders
- Elatum group
- Strong, upright growth
- Large, vibrant blooms
Taking cuttings ensures you preserve the exact traits of your favourite plants.
Ideal conditions for rooting
- Light
- Temperature
- Cool to moderate (10–15°C)
- Compost
- Free-draining, low nutrient
- Water
- Keep lightly moist
- Avoid overwatering
Delphiniums prefer cooler conditions compared to many other cuttings.
Common problems
Cuttings collapsing
- Cause: hollow stems or incorrect material
- Fix: use solid basal shoots only
Rotting
- Cause: overwatering or poor airflow
- Fix: improve drainage and ventilation
Slow rooting
- Cause: low temperatures or weak cuttings
- Fix: ensure healthy shoots and stable conditions
Wilting
- Cause: low humidity
- Fix: cover cuttings to retain moisture
Climate and regional notes
UK & Ireland
- March is ideal as plants begin active growth
- Often done under cover or in a cold frame
Europe
- Similar timing in northern regions
- Earlier in milder climates
USA
- Timing depends on local spring conditions
- Take cuttings as new growth appears
Pro tips for better success
- Take cuttings early in the day for best hydration
- Avoid using hollow stems
- Keep cuttings out of direct sunlight
