About Foxglove 'Camelot'

Digitalis purpurea 'Camelot' · also called Foxglove · flowering

'Camelot' is a first-year-flowering foxglove series bred to bloom from seed in a single season, producing sturdy, well-branched spires of large outward-facing bells in cream, lavender, rose and white. More uniform and weather-resistant than the wild type, it suits borders in part shade with moist, rich soil. All parts are poisonous.

Growth habit: Bred as a first-year-flowering biennial; behaves as a tall, well-branched short-lived perennial or biennial, often blooming the first summer from an early sowing.

Watch for — Flopping spikes: Tall spires can lean in wind or rich soil. Stake in exposed gardens and avoid over-feeding with nitrogen.

What fertiliser foxglove 'camelot' actually wants — and why

Foxglove 'Camelot' is an easy, light foliage feeder — a half-strength balanced liquid feed through the growing months keeps it green without forcing weak, sappy growth.

A balanced general houseplant feed (roughly even N-P-K) is exactly right — it is grown for foliage, so steady, moderate nitrogen for healthy leaves is the goal, not a bloom or root formula.

For the language behind the three numbers on the bottle — what nitrogen, phosphorus and potassium each do — see the NPK ratio explained entry. The short version for foxglove 'camelot': match the feed to the job the plant is doing right now, not to a generic “plant food” on the shelf.

How often to feed foxglove 'camelot', and which months

Feeding only earns its keep while the plant is in active growth and can use the nutrients — pour feed into a dormant or low-light plant and it simply builds up as root-burning salt. For foxglove 'camelot':

Feed lightly with a balanced fertiliser in spring, or rely on enriched soil and compost mulch. Avoid excess nitrogen, which weakens the flower spikes. Treat that as sparingly through the growing season between spring through early autumn (roughly March to September); ease off in autumn and stop entirely in the low light of winter.

The dormant-season rule matters more than the exact interval: skip feeding entirely when foxglove 'camelot' is resting. For the wider context on indoor feeding rhythms across the seasons, the houseplant fertiliser schedule walks through the year month by month.

What strength to mix for foxglove 'camelot'

Half strength is the safe default for foxglove 'camelot' — houseplant feeds are formulated strong, and the diluted dose is gentler on the roots while still ample for foliage.

Feeding always goes onto already-damp soil, never dry roots — water foxglove 'camelot' first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the foxglove 'camelot' watering schedule.

Signs you are over-feeding foxglove 'camelot'

Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for foxglove 'camelot':

Flushing and leaching the salts

Flush the pot of foxglove 'camelot' with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.

Organic vs synthetic feeds for foxglove 'camelot'

Organic options

A diluted seaweed or worm-casting feed, or fish emulsion if you can tolerate the smell indoors. UK: Westland or Baby Bio Organic, dilute seaweed; US: Espoma Indoor! or Neptune's Harvest fish & seaweed. Slow, gentle and hard to overdo.

Synthetic / liquid feeds

A general-purpose houseplant liquid at half strength — UK: Baby Bio, Westland Houseplant Feed or Phostrogen; US: Miracle-Gro Indoor Plant Food or Schultz. Convenient and fast-acting; the only risk is overdoing it.

Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.

Half strength is the safe default for foxglove 'camelot' — houseplant feeds are formulated strong, and the diluted dose is gentler on the roots while still ample for foliage.

What does over-feeding foxglove 'camelot' look like?

Brown, crispy leaf tips and edges with no sign of underwatering. A white, crusty salt deposit on the soil surface or pot rim. Weak, pale, stretched new growth that flops. Lower leaves yellow and drop while the soil is correctly watered. Feeding foxglove 'camelot' year-round on a fixed schedule, including dark winter months, is the most common mistake — it cannot use the nutrients in low light and the surplus simply burns the roots and crusts the soil.

Should I flush the soil of foxglove 'camelot'?

Flush the pot of foxglove 'camelot' with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.
