HOW TO GROW SPINACH
Quick Beginner Tips
- Spinach grows best in cooler months.
- Use mulch to keep roots cool.
- Partial afternoon shade helps in warmer Australian climates.
- Choose bolt-resistant varieties for spring growing.
1. Choose a Variety
Easy Bigginer Variety:
| Variety | Features |
|---|---|
| Bloomsdale | Classic savoy type |
| Baby Leaf Hybrid | Fast-growing and tender |
| Tyee | Bolt-resistant |
| Space | Good for containers |
| Red Cardinal | Decorative red stems |
2. Growing Timeline
| Month | Growth Stage | Tasks |
|---|---|---|
| February | Preparation | Choose cool-season varieties, prepare soil with compost, improve drainage, plan planting area |
| March | Planting Begins | Sow seeds directly into soil or pots, keep soil moist, protect from hot days |
| April | Germination & Early Growth | Thin seedlings, mulch lightly, begin regular watering |
| May | Leaf Development | Harvest baby leaves, feed lightly with nitrogen fertilizer, watch for slugs/snails |
| June | Strong Vegetative Growth | Continue harvesting outer leaves, maintain moisture, remove damaged leaves |
| July | Peak Growth | Frequent harvesting, protect from heavy frost if needed, continue feeding every few weeks |
| August | Mature Harvest Stage | Harvest full-size leaves or whole plants, succession sow for continuous crops |
| September | Late-Season Growth | Watch for bolting as weather warms, provide afternoon shade |
| October | Bolting Risk | Harvest remaining leaves quickly, remove flowering plants |
| November | End of Main Season | Clear old plants, add compost, prepare for summer crops |
| December | Rest / Avoid Growing | Spinach struggles in heat; grow heat-tolerant leafy greens instead |
| January | Preparation for Next Season | Improve soil, collect seeds if desired, plan autumn sowing |
3. Growing Conditions
- Fertile, loose, well-draining (6.5-7.5ph).
- Full sun to partial shade
- Cool to mild (10–22°C). Light frost tolerant.
4. Planting
Best Planting Time in Sydney: Autumn, Winter – Excellent, Early Spring – Good.
0. Prepare soil:
- Mix compost and aged manure before planting
1. Planting Steps
From Seeds (BEST METHOD): Spinach is usually grown directly from seed because it dislikes root disturbance and transplants can bolt or stall.
- Prepare soil and remove weeds or stones.
- Sow seeds 1–2 cm deep.
- Space rows 25–30 cm apart.
- Water gently after sowing.
- Thin seedlings when they reach 5–7 cm tall.
- Germination takes 5-14 days.
2. POT Planting
Best Varieties for Pots
| Variety | Features | Best For |
|---|---|---|
| Space | Compact and productive | Containers |
| Baby Leaf Hybrid | Fast-growing tender leaves | Small pots |
| Tyee | Bolt-resistant | Warm climates |
| Bloomsdale | Traditional crinkled leaves | General growing |
| Red Cardinal | Red stems and attractive foliage | Decorative edible pots |
Pot Size Guide
| Spinach Type | Minimum Pot Depth | Recommended Width |
|---|---|---|
| Baby spinach | 15–20 cm | 20–30 cm |
| Mature spinach | 20–25 cm | 30–40 cm |
| Multiple plants | 20–25 cm | Wide planter box preferred |
5. Watering
| Stage | Watering Needs |
|---|---|
| Germination | Keep soil evenly moist daily |
| Seedlings | Light watering every 1–2 days |
| Mature plants | Deep watering 1–2 times weekly |
| Warm weather | Water more frequently |
Tips
- Avoid letting soil dry out completely.
- Mulch helps retain moisture.
- Water early in the morning.
6. Supporting & Pruning
Supporting:
- Spinach usually does not require support.
- Shade cloth may help during warm spring weather.
- Wind protection helps prevent leaf damage.
Pruning:
| Task | Purpose |
|---|---|
| Remove yellow leaves | Prevent disease |
| Thin crowded plants | Improve airflow |
| Harvest outer leaves regularly | Encourage new growth |
| Remove flower stalks | Delay bolting |
7. Feeding
| Stage | Recommended Feeding |
|---|---|
| Before planting | Compost or aged manure |
| Early growth | Nitrogen-rich fertilizer |
| Every 2–3 weeks | Liquid seaweed or fish emulsion |
Feeding Tips
- Too much fertilizer may create soft weak leaves.
- Nitrogen promotes leafy growth.
8. Pollination
- Spinach is mainly wind-pollinated.
- Pollination is only important if growing plants for seed collection.
- Most gardeners harvest before flowering occurs.
9. Common Problems
| Problem | Symptoms | Solution |
|---|---|---|
| Bolting | Flower stalks appear early | Grow in cool weather; use shade cloth |
| Slugs & snails | Holes in leaves | Use traps or hand-pick |
| Aphids | Curled sticky leaves | Spray with water or insecticidal soap |
| Downy mildew | Yellow patches, fuzzy underside | Improve airflow; avoid wet leaves |
| Leaf miners | White tunnels inside leaves | Remove damaged leaves |
| Poor germination | Sparse seedlings | Keep soil moist and cool |
| Bitter leaves | Tough strong flavor | Harvest young leaves regularly |
10. Harvesting
| Harvest Type | Timing |
|---|---|
| Baby leaves | 20–30 days |
| Mature leaves | 35–50 days |
| Whole plant | 40–60 days |
Harvest Tips
- Pick outer leaves first.
- Harvest frequently for continuous production.
- Morning harvest gives best flavor and freshness.
11. Storage
| Method | Storage Time |
|---|---|
| Refrigerator | 5–10 days |
| Blanched & frozen | 8–12 months |
Storage Tips
- Store dry leaves in breathable bags.
- Wash just before use.
- Keep refrigerated immediately after harvest.
