Nerine

Nerine bowdenii

Shocking pink lily-like heads on bare stems in October, when the border is finished and nothing else is doing anything. It wants the opposite of what most bulbs want: baked, crowded, half out of the ground at the foot of a sunny wall, and left completely undisturbed.

Position: Full sun
Water: low demand
Drainage: Free-draining
Grows to: 45–60 cm × 8–15 cm
Hardiness: H4
Flowers: September to November
Difficulty: Some care needed

August

Nothing to do

No sowing, planting, harvesting or pruning window falls in August.

Coming next month: in flower.

Nerine’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.

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	Nerine 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 Nerine as it stands: The pH suits it: it wants 6 to 7.8, and this soil is in that range. The free drainage is exactly what it wants. Sandy soil is among the soils it is recorded as suiting. It stands dry conditions better than most, which this soil will test.
Chalky and alkaline	Prefers this soil	Chalky and alkaline suits Nerine as it stands: The free drainage is exactly what it wants. Chalky soil is among the soils it is recorded as suiting. It stands dry conditions better than most, which this soil will test.

Grow it deliberately crowded in a pot barely bigger than the bulbs, which is not neglect but the actual requirement — a nerine given room flowers badly for years while it fills the space. Necks above the compost, gritty free-draining mix, and stand the pot somewhere hot and dry all summer. Resist repotting until it is visibly bursting out.

Habit and ultimate size

What the plant becomes, rather than what it is when you buy it. The gap between the two is where most planting mistakes live.

Layered scales around a basal plate — an onion in cross-section. Multiplies by producing offsets alongside the parent, which can be pulled apart by hand when the clump is lifted.

Two to three times the bulb's own height is the working rule, and the four plants that break it are the four most often planted wrong. A bearded iris buried by mulch or a tidy neighbour will make leaves for years and never flower again.

After flowering. The leaves appear after the flowers and stand through winter, so they need a dry mulch rather than tidying in a cold garden. It flowers best crowded and undisturbed, so resist dividing it.

Where and how you can grow it

Each way of growing is assessed separately, and “not assessed” is a real answer rather than a gap we have filled in with a guess.

Growing it

PlantingPlant the bulbs shallowly with their necks showing above the surface, at the base of a south-facing wall, and then leave them alone. Nerine flowers best when congested and baked, so the usual instincts — planting deep, improving the soil, dividing when crowded — all reduce the flowering rather than improving it.
ProtectionThe leaves appear after the flowers and stay through the winter, so they need protection from the worst frost in a cold garden — a dry mulch over the crowns rather than anything that holds wet.
WateringThe plant whose whole cultivation is a watering rhythm, run in reverse from everything around it. Keep it completely dry through the summer while it is dormant and the bulbs are baking — this is what triggers flowering, and a nerine that is watered in July gives leaves and no flowers. Start watering when the flower buds push up in September, continue through the winter while the strappy leaves are growing, and stop again when they yellow in late spring. Bulbs planted with their necks above the soil, as they should be, are much harder to overwater by accident.
FeedingFeed with a high-potash liquid feed through the winter and early spring while the leaves are growing, which is when the bulb is rebuilding itself for next October. Stop when the foliage begins to yellow. Do not feed during flowering and do not use anything high in nitrogen — nerines flower best when hungry, crowded and hot, and a well-fed, well-spaced, recently divided clump is the classic recipe for years of good foliage and nothing else.
