About 'Fairy Tale' Aubergine
Solanum melongena 'Fairy Tale' · also called Fairy Tale eggplant, Mini aubergine · edible
'Fairy Tale' is an award-winning mini aubergine bearing clusters of small, slender purple-and-white streaked fruits with sweet, tender, nearly seedless flesh and no bitterness. Compact and early-maturing at about 50-65 days, it crops well in containers and short seasons, making it one of the easiest aubergines for patios and cooler-climate gardeners.
Growth habit: Compact, bushy tender perennial grown as an annual, branching low with fruits borne in clusters of 4-6. Its dwarf stature often needs no staking, though a single cane steadies heavily laden plants; little pinching required.
What fertiliser 'fairy tale' aubergine actually wants — and why
'Fairy Tale' Aubergine feeds in two distinct phases — balanced to build the plant, then high-potassium the moment flowering starts to set and fill a heavy crop.
Balanced (even N-P-K) at planting for roots and frame, then switch to a high-potassium ("high-potash") tomato-style feed once the first flowers open — potassium is what sizes and ripens fruit, not nitrogen.
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 'fairy tale' aubergine: 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 'fairy tale' aubergine, 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 'fairy tale' aubergine:
Feed weekly with a high-potassium tomato-type liquid feed once flowering starts to keep the heavy clusters cropping. Go easy on nitrogen, which favours leaves over fruit. So: a balanced feed or compost at planting, then a high-potash liquid every 1-2 weeks from first flower through harvest across the main season (spring through early autumn).
The dormant-season rule matters more than the exact interval: skip feeding entirely when 'fairy tale' aubergine 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 'fairy tale' aubergine
Follow the crop-feed label rate for 'fairy tale' aubergine — these are calibrated for hungry vegetables. Consistency through fruiting matters more than strength; erratic feeding causes problems like blossom-end rot.
Feeding always goes onto already-damp soil, never dry roots — water 'fairy tale' aubergine first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the 'fairy tale' aubergine watering schedule.
Signs you are over-feeding 'fairy tale' aubergine
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for 'fairy tale' aubergine:
- Vigorous dark-green leafy growth but few flowers or fruit (excess nitrogen).
- Lush foliage hiding the crop; soft growth prone to pests and disease.
- Salt crust on the soil and scorched leaf edges in containers.
Signs you are under-feeding 'fairy tale' aubergine
- Pale, yellowing lower leaves and stunted growth.
- Small fruit, poor set, and a quickly exhausted plant.
- Blossom-end rot and weak cropping from erratic or insufficient feeding.
If the symptoms point at watering, light or roots rather than nutrition, the full 'fairy tale' aubergine care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
In containers, fertiliser salts build up fast — water 'fairy tale' aubergine thoroughly so excess drains from the base each time, and flush pots with plain water every few weeks to prevent a damaging salt build-up.
Organic vs synthetic feeds for 'fairy tale' aubergine
Organic options
Garden compost or well-rotted manure dug in before planting, plus a liquid comfrey or seaweed feed once fruiting starts. UK: comfrey feed or organic Tomorite; US: Espoma Tomato-tone or Neptune's Harvest. Builds soil and feeds in one.
Synthetic / liquid feeds
A balanced feed at planting then a high-potash tomato feed in fruiting — UK: Growmore at planting then Tomorite (Levington) or Phostrogen; US: a balanced 10-10-10 then Miracle-Gro Tomato or a bloom booster.
Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.

What does over-feeding 'fairy tale' aubergine look like?
Vigorous dark-green leafy growth but few flowers or fruit (excess nitrogen). Lush foliage hiding the crop; soft growth prone to pests and disease. Salt crust on the soil and scorched leaf edges in containers. Staying on a high-nitrogen feed once 'fairy tale' aubergine starts flowering is the classic error — you get a huge leafy plant and a disappointing crop. Switch to high-potash the moment flowers appear.
Should I flush the soil of 'fairy tale' aubergine?
In containers, fertiliser salts build up fast — water 'fairy tale' aubergine thoroughly so excess drains from the base each time, and flush pots with plain water every few weeks to prevent a damaging salt build-up.
