FAQs
When is the best time to sow Noel Sutton Sweet Peas?
You can sow indoors or outdoors from January to April and again from September to October. Autumn sowing typically results in earlier flowering the following year.
How tall do these sweet peas grow?
As a Spencer type, they are vigorous climbers and require support up to approximately 1.8 meters (6 feet).
Do I need to feed these sweet peas?
Yes, regular feeding with a suitable plant fertilizer, especially during the flowering season, will help ensure continuous blooming.
Can I grow these in pots?
Absolutely. They are ideal for large containers, provided they have adequate depth, drainage, and support.
How far apart should I plant them?
Space the plants about 20cm (8 inches) apart when planting out.
Why should I pinch out the seedlings?
Pinching out the tips of young seedlings (when they are 7-10cm tall) encourages the plant to branch out, resulting in a bushier plant with more stems and flowers.
When do they typically flower?
Flowering usually occurs from May through August, depending on sowing time and local conditions.
Troubleshooting
Seeds not germinating
Ensure consistent moisture and temperature (around 15°C). Try pre-soaking or using the moist kitchen roll method. Check seed viability if old.
Seedlings are leggy and weak
Provide more light and cooler temperatures after germination. Ensure adequate spacing between plants.
No flowers or few flowers
Ensure plants are receiving adequate sunlight, water, and nutrients. Pinching out the tips encourages more flowering stems. Regular harvesting of blooms also promotes further flowering.
Plants falling over
Ensure adequate support (canes, netting) is installed early and plants are tied in as they grow. Check that the support is stable.
Yellowing leaves
This can indicate overwatering or nutrient deficiency. Check soil moisture and consider a balanced liquid feed.

Setup, Compatibility & Care
Sowing Indoors:
- Place seeds on moist kitchen roll in an airtight container and keep in a warm room until they swell or sprout.
- Alternatively, soak seeds overnight and sow immediately.
- Sow seeds individually in rootrainers or 8cm pots, 1cm deep.
- Water lightly after sowing and keep at around 15°C until germinated.
Growing On / Planting Out:
- Once seedlings reach 7–10cm tall, pinch out the tips to promote bushier growth and more flowers.
- Keep plants in a cool, bright location. Autumn-sown seedlings should be protected in a cold frame, greenhouse, or under a cloche.
- Plant out seedlings 20cm apart from late March onwards, once the weather is milder, in a sunny position. Avoid disturbing the root system during transplanting.
Sowing Outdoors:
- Choose a sunny spot and pre-water the soil, enriching it with compost.
- Sow seeds 2cm deep and about 7cm apart.
- Keep the soil consistently moist until seedlings emerge.
- Thin seedlings to approximately 20cm apart once they are more established.
Aftercare:
- Support: Provide sturdy support such as canes, netting, or a trellis reaching about 1.8m high. Tie stems to the support regularly as the plants grow.
- Watering & Feeding: Water regularly, especially during dry spells, and feed with a suitable plant food to encourage continuous flowering.
- Harvesting: Pick flowers frequently to promote the plant to produce more blooms.
