Growing Sweet Peas from Seed Indoors: A Step-by-Step Guide

Sweet peas (Lathyrus odoratus) are one of the most beautiful and fragrant flowers to grow in a garden. Starting sweet peas from seed indoors gives you a head start on the growing season, resulting in stronger plants and earlier flowers.

Whether you’re growing annual sweet peas for fragrance or perennial sweet peas for long-term blooms, starting them indoors in winter or early spring is the best way to ensure healthy, robust plants.

In this guide, you’ll learn:

✔️ The best time to start sweet pea seeds indoors
✔️ How to plant and care for sweet pea seedlings
✔️ The importance of root trainers and pre-soaking seeds
✔️ How to transplant sweet peas outdoors successfully

Let’s get started on growing sweet peas from seed indoors like a pro! ??

1. When to Start Sweet Peas Indoors?

The best time to sow sweet peas indoors depends on how early you want flowers.

Recommended Sowing Times:

✔️ Autumn Sowing (October–November) – Produces stronger, earlier-flowering plants in spring.
✔️ Winter Sowing (January–February) – Ideal for an early start before spring planting.
✔️ Early Spring Sowing (March–April) – Best for direct planting in spring gardens.

Tip: The earlier you sow sweet peas indoors, the bigger and stronger the plants will be when moved outside.

2. How to Grow Sweet Peas from Seed Indoors (Step-by-Step Guide)

Step 1: Gather Your Materials

✔️ Sweet pea seeds (Choose fragrant varieties like ‘Cupani’ or ‘Spencer Mix’)
✔️ Root trainers or deep pots (For strong root development)
✔️ Seed compost (Light, well-draining soil)
✔️ Watering can with a fine rose (For gentle watering)
✔️ Grow lights or a sunny windowsill

Tip: Sweet peas have long roots, so deep containers like root trainers or toilet rolls work best.

Step 2: Pre-Soak Seeds for Faster Germination

Sweet pea seeds have a hard outer shell, which can slow down germination.

✔️ Soak seeds in warm water overnight (12–24 hours).
✔️ This softens the seed coat, helping them sprout faster.
✔️ If seeds don’t swell, gently nick the outer shell with a nail file.

Tip: Some gardeners don’t soak their seeds, but it can speed up germination by a few days.

Step 3: Sowing Sweet Pea Seeds Indoors

✔️ Fill root trainers or deep pots with seed compost.
✔️ Sow one seed per pot, pushing it 2–3 cm (1 inch) deep.
✔️ Cover lightly with compost and firm down gently.
✔️ Water lightly but evenly to avoid overwatering.

Tip: Avoid planting too shallow—deep roots help support strong growth.

Step 4: Provide the Right Growing Conditions

? Temperature: Keep seeds at 15–18°C (59–64°F) for best germination.
? Light: Place on a bright windowsill or under grow lights.
? Watering: Keep compost moist but not soggy.

Germination Time: ? 7–14 days (depending on variety and conditions).

Tip: Once seedlings appear, move them to a cooler place (10–12°C/50–54°F) to prevent leggy growth.

3. How to Care for Sweet Pea Seedlings Indoors

1. Pinching Out for Bushier Growth

✔️ Once seedlings reach 10 cm (4 inches) tall, pinch out the growing tip just above a pair of leaves.
✔️ This encourages stronger, bushier plants with more side shoots and flowers.

Tip: Don’t pinch out perennial sweet peas—they don’t respond well to it.

2. Watering & Feeding

✔️ Water only when the compost feels dry—too much water causes weak growth.
✔️ No fertilizer needed until seedlings are planted outside.

3. Providing Support

✔️ As seedlings grow, use small sticks or canes to train them.
✔️ This prevents them from tangling and encourages strong stems.

Tip: Sweet peas are natural climbers, so they attach to supports easily once planted out.

4. Transplanting Sweet Peas Outdoors

After 6–8 weeks, sweet peas will be ready for planting outdoors.

When to Plant Sweet Peas Outside

✔️ March–May – After the risk of frost has passed.
✔️ Harden off for 7–10 days before transplanting.

How to Harden Off Sweet Peas Before Planting

✔️ Move seedlings outside during the day for increasing amounts of time.
✔️ Keep them sheltered from wind and rain at first.
✔️ After 7–10 days, they’ll be ready for full outdoor conditions.

Tip: If a late frost is expected, cover young plants with horticultural fleece at night.

5. How to Plant Sweet Peas in the Garden

Once hardened off, follow these steps for successful transplanting.

✔️ Choose a sunny, sheltered spot—Sweet peas love full sun.
✔️ Improve soil with compost or well-rotted manure before planting.
✔️ Space plants 20–30 cm (8–12 inches) apart.
✔️ Water well after planting to help roots establish.

Providing Support for Sweet Peas

✔️ Use canes, trellises, or netting for climbing varieties.
✔️ Tie stems loosely to supports with twine as they grow.

Tip: Pinch off flowers regularly to encourage continuous blooming throughout the summer!

6. Common Problems & Solutions

Tip: Sweet peas are frost-hardy, but young plants still need protection from extreme cold.

7. Final Thoughts: Growing Sweet Peas from Seed Indoors

✔️ Start sweet peas indoors in autumn, winter, or early spring for stronger plants.
✔️ Use deep root trainers or pots to encourage healthy root growth.
✔️ Pre-soak seeds before sowing to speed up germination.
✔️ Pinch out young plants for bushier growth and more flowers.
✔️ Harden off seedlings before transplanting outdoors in March–May.

By following these step-by-step tips, you’ll enjoy beautiful, fragrant sweet pea flowers all summer long! ??
