🥬 Sowing: In Trays vs. Direct in the Garden

You’ve got two solid options when it comes to sowing: in trays for more control, or direct in the garden for ease. Both have their place depending on your setup and the season.

🌱 Sowing in Trays

Sowing into trays is ideal if you’re starting early in the season, want to avoid pests, or just prefer the predictability of transplanting strong seedlings. Fill seed trays or punnets with quality seed-raising mix, and sow seeds about 1 cm deep. Water in gently.

Perpetual spinach germinates reliably, usually in 7–14 days. A warm spot helps, so in cooler regions, keep trays in a greenhouse or sunny windowsill.

Once the seedlings have two sets of true leaves and roots hold the mix together, harden them off for a few days outside before transplanting into the garden.

🌿 Direct Sowing

This is the quicker route and works well in late summer through early autumn, or again in early spring when the soil is still warm. Sow seeds directly into prepared beds about 1 cm deep and 20–30 cm apart, thinning to the strongest seedlings once they emerge.

Direct sown plants are often sturdier because they don’t go through transplant shock, but you’ll need to keep a closer eye on snails and slugs.

🌾 Is Seed Pre-treatment Required?

No pre-treatment is strictly necessary, but soaking the seeds overnight can help soften their hard seed coat and improve germination rates. If you’re sowing in cooler weather, this little trick can make a difference.

🌞 Soil & Position

Perpetual spinach is wonderfully adaptable, but to get lush, leafy growth, give it the best footing you can:

• Position: Full sun to part shade. In very hot zones, a little afternoon shade is welcome.
• Soil: Free-draining, rich in organic matter, and well-worked. Think compost, aged manure, and a sprinkle of lime if your soil is acidic.
• pH: Neutral to slightly alkaline (6.5–7.5).
• Tip: Avoid planting in beds where you’ve recently grown other leafy greens to help prevent disease buildup.

🌱 Care & Maintenance

Once your plants are in the ground and settled, they’re remarkably low maintenance. Here’s how to keep them thriving:

• Watering: Keep soil evenly moist, especially when young. Mulching helps hold moisture and suppress weeds.
• Feeding: Feed fortnightly with a diluted liquid fertiliser (like seaweed or fish emulsion) or side-dress with compost every month or so.
• Mulching: Mulch around plants to suppress weeds, conserve water, and protect the root zone.
• Harvesting Leaves: Pick the outer leaves regularly to encourage new growth from the centre.

This regular harvest is key to “perpetual” productivity.

🌼 Companion Planting Guide

Perpetual spinach is a friendly garden neighbour and fits beautifully into most crop rotations.

Great companions:

• Brassicas (like cabbage, kale, and broccoli): They enjoy similar soil and feeding.
• Onions and leeks: Help deter pests and don’t compete much for space.
• Marigolds and nasturtiums: Natural pest deterrents that also add a pop of colour.

Avoid planting with:

• Runner beans: They can compete for nutrients and space.
• Strawberries: May struggle with similar nutrient needs.

✂️ Harvesting

You can begin harvesting once the plants have a decent bunch of leaves—usually 6–8 weeks after sowing.

• Harvest outer leaves first, cutting at the base with a sharp knife or pulling gently.
• Avoid damaging the central crown—this is the growth point for new leaves.
• The more you pick (within reason), the more the plant produces!

You can often get 6–12 months of production from one planting, especially in temperate areas.

🐛 Common Issues and Fixes

Here’s a quick table to help you troubleshoot the most common problems.

Problem	Cause	Fix
Yellowing leaves	Nitrogen deficiency or overwatering	Feed with a high-nitrogen fertiliser and check drainage
Leaf miners	Insect larvae burrowing in leaves	Remove and destroy affected leaves, use row covers if needed
Snails and slugs	Moist soil or dense mulch	Use traps, beer saucers, or sprinkle crushed eggshells as deterrent
Bolting (flowering too early)	Heat stress or age	Plant during cooler months, pick leaves often to delay flowering
Powdery mildew	Poor air flow or high humidity	Space plants well, remove affected leaves, avoid overhead watering

🌼 Seed Saving Guide

Saving seeds from perpetual spinach is simple and satisfying, but it does take a bit of time and planning.

1. Let it Bolt: In its second year (it’s a biennial), select your healthiest plants and let them flower and go to seed. Stake them if needed—they can get tall!
2. Pollination: Wind does most of the work here. Grow at least a few plants to ensure good cross-pollination.
3. Wait for Drying: Once seeds form, let the seed heads dry out on the plant as much as possible. They’ll go brown and papery.
4. Harvest: Snip off dry seed heads and place in a paper bag to finish drying.
5. Thresh and Clean: Rub between your hands to free the seeds, then winnow gently to remove the chaff.
6. Store: Keep seeds in a cool, dry place in a labelled envelope or jar. They’ll stay viable for 2–4 years.

🌿 Final Thoughts

Perpetual spinach really lives up to its name. It’s a generous, forgiving crop that suits new and experienced gardeners alike. Whether you’ve got a raised bed, a no-dig patch, or just a few pots on the balcony, there’s room for this leafy staple in any garden.

Just remember: healthy soil equals healthy greens, and regular picking keeps the plant producing. Give it a bit of love, and it’ll return the favour tenfold.
