Golden-scaled male fern
Dryopteris affinis
The male fern's larger and more imposing relation, distinguished by a dense covering of golden-brown scales on the unfurling croziers in spring and by a dark spot where each leaflet joins the midrib. Semi-evergreen, so it stands through a mild winter and collapses in a hard one.

Nothing to do
No sowing, planting, harvesting or pruning window falls in August.
Coming next month: plant.
Golden-scaled male fern’s year
Resolved for United Kingdom (general). Every window is stored against a climate event rather than a date, so a late frost pocket runs later than the band shows. What else August calls for.

Timing that travels
The band above resolves this plant's windows into months for one region. These are the windows themselves, stored against a climate event rather than a date — which is the form that survives being carried to a colder garden, a frost pocket, or next year.

On your soil
Computed by comparing this plant's recorded requirements against each soil's recorded characteristics. A recorded horticultural fact overrides the comparison where GrowingHQ holds one.
| Soil | Verdict | Why |
|---|---|---|
| Heavy clay | Works, with one condition | Golden-scaled male fern will crop on heavy clay, but one thing has to be dealt with first. It needs ground that drains, and this soil holds water. A plant that stays in the ground through winter with its roots in cold, saturated soil rots — which is what kills most of what fails on heavy ground, rather than the cold.Improve the drainage before planting — a raised bed, or bulky organic matter worked in over several seasons. Do not add sand to clay in small quantities; it makes the problem worse. |
| Sandy | Prefers this soil | Sandy suits Golden-scaled male fern as it stands: The pH suits it: it wants 5 to 7.5, and this soil is in that range. The free drainage is exactly what it wants. It stands dry conditions better than most, which this soil will test. |
| Chalky and alkaline | Grows well here | Golden-scaled male fern grows perfectly well on chalky and alkaline without special measures, though it is not the soil it would choose. |
| Loam | Prefers this soil | Loam suits Golden-scaled male fern as it stands: The pH suits it: it wants 5 to 7.5, and this soil is in that range. The free drainage is exactly what it wants. Loam is among the soils it is recorded as suiting. The soil holds moisture, which saves a great deal of watering. |
| Silty | Prefers this soil | Silty suits Golden-scaled male fern as it stands: The pH suits it: it wants 5 to 7.5, and this soil is in that range. The free drainage is exactly what it wants. The soil holds moisture, which saves a great deal of watering. |
| Peaty and acid | Works, with one condition | Golden-scaled male fern will crop on peaty and acid, but one thing has to be dealt with first. It needs ground that drains, and this soil holds water. A plant that stays in the ground through winter with its roots in cold, saturated soil rots — which is what kills most of what fails on heavy ground, rather than the cold.Improve the drainage before planting — a raised bed, or bulky organic matter worked in over several seasons.

| Shallow over rock | Prefers this soil | Shallow over rock suits Golden-scaled male fern as it stands: The free drainage is exactly what it wants. Loam is among the soils it is recorded as suiting. It stands dry conditions better than most, which this soil will test. |
| Made ground and urban soil | Works, with one condition | Golden-scaled male fern will crop on made ground and urban soil, but one thing has to be dealt with first. It needs ground that drains, and this soil holds water.

Growing it
- PruningSemi-evergreen rather than evergreen, and the distinction changes the job. After a mild winter the old fronds are still worth having and should be left; after a hard one they are brown and should come off. Judge the plant rather than the calendar.
- PlantingGive it more room than looks necessary. It reaches well over a metre across in good conditions and a plant squeezed against a path has to be cut back on one side every year, which spoils the symmetry that is the whole point of it.
