Pea Tendril Microgreen Seeds

Pea Tendril microgreens produce substantial green shoots with crisp stems, tender leaves and curling tendrils. They are grown slightly longer than very young pea shoots where more developed tendrils are desired.

What You Need

• Pea Tendril Microgreen Seeds
• A 25 × 50cm tray with drainage holes
• A solid lower tray for bottom watering
• Coco coir, quality soil-based microgreen mix or another supportive growing medium
• A clean soaking container
• Clean drinking-quality water
• A second tray for covered germination
• Bright natural light or suitable grow lights
• Clean scissors or a sharp harvesting knife

Seed Rate

For a standard 25 × 50cm microgreen tray, use approximately:

230–280g dry pea seed per tray

Measure the seed before soaking.

Peas are large seeds and require a substantially heavier sowing rate than small-seeded microgreens.

Spread the soaked peas into a dense, relatively even layer while avoiding deep piles or excessive overlapping.

Pre-Soak

Pre-soak for approximately:

6–8 hours

1. Measure the required dry seed.
2. Rinse thoroughly with clean drinking-quality water.
3. Place the peas in a large clean container.
4. Cover generously with cool water.
5. Soak for approximately 6–8 hours.
6. Drain thoroughly before sowing.

Peas absorb a substantial amount of water and expand considerably, so use a container with plenty of additional space.

Prepare the Growing Medium

Pea shoots develop vigorous root systems and benefit from a supportive growing medium.

Suitable options include:

• coco coir;
• fine seed-raising mix;
• quality soil-based microgreen mix;
• fine propagation mix; or
• another supportive, well-drained microgreen medium.

Add approximately:

2–4cm of growing medium

Level the surface and moisten it thoroughly before sowing.

The medium should be evenly damp without being waterlogged.

Sow the Peas

1. Drain the soaked peas thoroughly.
2. Spread them evenly across the prepared growing surface.
3. Aim for a dense, nearly continuous layer without creating deep piles.
4. Press the peas firmly into contact with the growing medium.
5. Mist lightly if required.
6. Apply a light covering of fine growing medium or vermiculite if preferred.
7. Place another tray on top during early establishment.

Good seed-to-medium contact is particularly important with peas because their large seeds sit above the growing surface more readily than small seeds.

Covered Germination

Keep the tray covered or stacked for approximately:

3–5 days

Light-to-moderate tray pressure can help maintain seed-to-medium contact while the roots establish.

Heavy compression is unnecessary.

Check the crop every day and uncover once the majority of germinated shoots are firmly rooted and pushing strongly upward.

For more information about covered germination, see Microgreen Blackout Explained.

Germination

Expect germination in approximately:

2–4 days

Roots usually develop first, followed by pale shoots.

Do not compensate for slower or ungerminated seeds by keeping the tray excessively wet.

Large hydrated pea seeds can deteriorate when kept continually saturated.

Temperature

Aim for approximately:

15–22°C

Pea shoots generally favour cool to moderate growing conditions.

Avoid warm, stagnant environments with very high humidity, particularly while the dense seed layer is covered.

Light

Once the shoots are firmly established:

1. Remove the upper tray or blackout cover.
2. Move the crop into bright indirect natural light or beneath suitable grow lights.
3. Maintain good airflow.
4. Rotate the tray where required for even growth.

The pale emerging shoots should quickly develop fresh green colour.

As the crop matures, leaves expand and curling tendrils become increasingly visible.

Watering

Once roots establish, bottom watering is preferable.

For detailed guidance, see How to Water Microgreens: Misting vs Bottom Watering.

When bottom watering:

• keep the growing medium consistently moist;
• avoid permanent saturation;
• do not leave standing water beneath the tray;
• minimise repeated wetting of leaves and tendrils; and
• maintain good airflow through the canopy.

Established pea shoots use considerably more water than many smaller microgreens.

Check the growing medium regularly rather than allowing the root mat to dry completely.

Tips for Best Results

• Use approximately 230–280g per 25 × 50cm tray.
• Measure the seed before soaking.
• Pre-soak for approximately 6–8 hours.
• Drain thoroughly before sowing.
• Press the peas firmly against the growing medium.
• Use light-to-moderate pressure during early establishment.
• Keep covered for approximately 3–5 days.
• Expect germination in approximately 2–4 days.
• Maintain approximately 15–22°C.
• Provide bright light once uncovered.
• Maintain good airflow.
• Bottom water once established.
• Allow extra growing time for more developed tendrils.
• Harvest while the stems remain tender.

Growing for More Pronounced Tendrils

Young pea shoots can be harvested before substantial tendrils develop.

If the aim is a more pronounced tendril crop, allow the plants additional time under good light.

As the crop develops:

• leaves become larger;
• stems become taller;
• curling tips become increasingly visible; and
• the canopy becomes more substantial.

Do not extend the growing period purely to obtain larger tendrils if the stems are beginning to become coarse or fibrous.

Natural Variation in Tendril Development

Individual pea plants do not always produce identical tendril growth.

Within the same tray, some shoots may develop:

• longer curling tendrils;
• shorter tendrils;
• more leaf development; or
• less obvious curling growth.

This natural variation does not necessarily make the shoots unsuitable for harvest.

Seed-to-Medium Contact

Large soaked peas benefit from firm contact with the growing medium.

After sowing, press them down evenly and use an upper tray during establishment.

This helps:

• improve moisture access;
• anchor developing roots;
• reduce movement of the large seeds; and
• produce a more uniform canopy.

Commercial microgreen guidance commonly uses stacking or tray pressure for pea shoots during germination.

Avoid Overwatering the Seed Layer

Soaked pea seeds already contain considerable moisture.

During early establishment:

• keep the growing medium moist;
• allow excess water to drain;
• avoid continually soaking the peas from above; and
• remove soft or deteriorating seeds when practical.

Persistent saturation around large pea seeds can encourage deterioration.

Root Hairs vs Mould

Peas develop vigorous white roots and fine root hairs that can sometimes look like mould.

Healthy root hairs generally:

• grow directly from individual roots;
• appear relatively evenly;
• become more visible as the root zone dries slightly; and
• become less noticeable immediately after watering.

Mould is more likely to:

• spread irregularly between pea seeds;
• form web-like patches;
• persist after watering; or
• occur with soft seed, slime or sour smells.

If you are uncertain, see Mould vs Root Hairs on Sprouts & Microgreens.

Discard crops showing clear signs of spoilage.

Harvest

Harvest approximately:

10–16 days from sowing

For a more developed tendril crop, harvest towards the later part of the range only while the shoots remain tender.

The crop is generally ready when:

• shoots are approximately 10–15cm tall;
• stems remain crisp;
• leaves are fresh green;
• curling tendrils are developing;
• the shoots have a fresh, mildly sweet pea flavour; and
• the crop has not become coarse or fibrous.

Cut cleanly above the growing medium using clean scissors or a sharp harvesting knife.

Harvest & Storage

Where practical, harvest when the foliage is relatively dry.

For more detailed guidance, see How to Harvest & Store Microgreens.

For refrigerated storage:

1. Keep harvested shoots as dry as practical.
2. Place them loosely in a clean container.
3. Refrigerate promptly.
4. Avoid crushing the stems, leaves and curling tips.

If washed before storage, drain and dry thoroughly first.

Culinary Use

Pea Tendril microgreens work particularly well in:

• salads;
• sandwiches;
• wraps;
• grain bowls;
• noodles;
• rice dishes;
• egg dishes;
• vegetables; and
• quick stir-fries.

When cooking, add the shoots near the end so they soften slightly while retaining some fresh texture.

Regrowth After Harvest

Pea shoots can sometimes produce regrowth when sufficient lower stem and growing nodes remain after cutting.

A second cut may be possible, but it is usually:

• less uniform;
• lower yielding; and
• slower than the first harvest.

For best quality, treat the first cut as the primary harvest.

Clean Growing / Food Safety

Use clean soaking containers, trays, fresh growing medium, drinking-quality water and clean harvesting equipment.

Pay particular attention to:

• thoroughly rinsing seed before soaking;
• complete drainage after soaking;
• avoiding standing water;
• maintaining good airflow;
• removing deteriorating seeds;
• using clean harvesting equipment; and
• refrigerating harvested shoots promptly.

Discard pea shoots showing visible mould, slime, rotting seed, abnormal discolouration, sour smells or other signs of spoilage.

Seed Storage

Store unused pea seed sealed in a cool, dry and dark place away from heat, moisture and direct sunlight.

For longer-term storage, refrigeration can help maintain seed viability. Keep refrigerated seed sealed while it returns to room temperature before opening to reduce condensation.
