About Daylily 'Little Grapette'
Hemerocallis 'Little Grapette' · also called Little Grapette daylily, purple miniature daylily · flowering
Hemerocallis 'Little Grapette' is a highly popular award-winning miniature daylily bearing deep purple-violet blooms with a yellow-green throat on short, well-branched scapes in mid-summer. Extremely prolific and ideal for containers, edging, and small spaces. Toxic to cats — ingestion of any plant part, including pollen, can cause life-threatening acute kidney failure.
Growth habit: Compact clump-forming deciduous perennial
Watch for — Rootbound in containers: The prolific, fibrous root system fills containers quickly. Repot or divide every 1-2 years to prevent stunted growth and reduced flowering in container-grown plants.
What fertiliser daylily 'little grapette' actually wants — and why
Daylily 'Little Grapette' 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 daylily 'little grapette': 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 daylily 'little grapette', 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 daylily 'little grapette':
Apply a balanced granular fertiliser in spring. A mid-season liquid feed with a bloom formula (higher P/K) after the first flush encourages continued prolific flowering. Container-grown plants need more frequent feeding — a diluted balanced liquid fertiliser fortnightly during the growing season. 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 daylily 'little grapette' 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 daylily 'little grapette'
Half strength is the safe default for daylily 'little grapette' — 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 daylily 'little grapette' first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the daylily 'little grapette' watering schedule.
Signs you are over-feeding daylily 'little grapette'
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for daylily 'little grapette':
- 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.
Signs you are under-feeding daylily 'little grapette'
- Uniformly pale or yellow-green leaves, oldest first.
- Noticeably small new leaves and stalled growth in good light and season.
- A generally tired, lacklustre look despite correct watering and light.
If the symptoms point at watering, light or roots rather than nutrition, the full daylily 'little grapette' care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush the pot of daylily 'little grapette' 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 daylily 'little grapette'
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.
