Move through the SoilCommander growing library like a course: keep the navigation in place, open the next lesson, and build your garden plan step by step.
Sow March-August into soil enriched the previous autumn with compost or aged manure (RHS).
Leaf growth
3
Young foliage ready for salads within about 8 weeks; large, dark green ribbed leaves develop on thick edible stems (RHS).
Bolt-resistant cropping
4
Shows markedly better bolt resistance than true spinach, continuing to produce through summer heat that would finish ordinary spinach (RHS, grower consensus).
Cut-and-come-again harvest
8
Harvest outer leaves once sufficiently large; a single sowing supports year-round, repeated cut-and-come-again picking (RHS).
When to pick: Harvest outer leaves once sufficiently large; young foliage suitable for salads within about 8 weeks of sowing. Cut-and-come-again picking allows a year-round harvest from a single March-August sowing window (RHS).
Large, dark green ribbed foliage and thick, edible stems, resembling and tasting similar to spinach but with superior resistance to bolting, even during drought. Not native to GB/Ireland. Hardiness H4 (-10 to -5C). Full sun or partial shade. Soil: clay, loam; moist but well-drained; acid, neutral or alkaline pH; compost or aged manure incorporated in autumn. Height/spread 0.1-0.5m. Time to maturity 1-2 years. Propagate by seed. Pests: birds, cutworms, lettuce root maggots, root aphids, root knot eelworms, slugs, snails. Diseases: grey mould, lettuce downy mildew, mosaic virus, ring spot. Harvest outer leaves once sufficiently large; young foliage suitable for salads within about 8 weeks. Sow March-August for year-round harvesting via cut-and-come-again.

Frequently Asked Questions
What soil pH do perpetual spinach need?
A pH of about 6–7.5. That span reflects genuine variation between the authorities we cite rather than a single agreed figure — the References section lists each source's exact range.
What problems affect perpetual spinach?
Our data links 4 diseases and 5 pests to this crop. See the sections above for each one and how to manage it.
Plan next season before the problems start
This page gives you the thresholds; the planner turns them into your own calendar. It works from what you can observe and measure in your garden rather than from dates written for somebody else’s latitude.
Science-based growing guides · Thresholds that hold in any climate
This guide states the conditions the plant itself responds to — soil temperature, frost tolerance, day length — rather than dates, because the same calendar month means opposite seasons in the northern and southern hemispheres. Anything genuinely restricted to one part of the world is named as such rather than presented as universal. Written and maintained by our editorial team against international horticultural research and extension sources.
Sketch your exact plot shape, pick your crops, and get a spacing-accurate bed layout with companion pairings and a rotation plan. Spacing, companion pairings and rotation are the same in every climate and both hemispheres — pair the layout it gives you with when to plant to set your own timing from soil temperature.
