About Tigerella Tomato
Solanum lycopersicum 'Tigerella' · also called Tigerella tomato, Mr Stripey tomato · edible
Tigerella is an early, cordon (indeterminate) tomato bearing golf-ball-sized red fruit striped with orange-gold, ripening in roughly 55-75 days. It is tangy, heavy-cropping and reliable in cooler UK summers. Grow in full sun under glass or outdoors after frost, side-shoot regularly, and feed once the first truss sets.
Growth habit: Indeterminate (cordon) vine that grows tall and needs supporting on a cane or string; pinch out side-shoots and stop the leader once 5-7 trusses have set.
Watch for — Few fruit set: Caused by too much nitrogen, poor pollination or temperatures over ~30°C. Switch to high-potash feed at flowering and tap or shake plants to aid pollination.
What fertiliser tigerella tomato actually wants — and why
Tigerella Tomato 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 tigerella tomato: 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 tigerella tomato, 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 tigerella tomato:
Once the first fruit truss sets, feed weekly with a high-potash tomato fertiliser. Excess nitrogen gives lush leaves and few fruit, so switch from balanced to high-potash feed at flowering. 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 tigerella tomato 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 tigerella tomato
Follow the crop-feed label rate for tigerella tomato — 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 tigerella tomato first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the tigerella tomato watering schedule.
Signs you are over-feeding tigerella tomato
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for tigerella tomato:
- 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 tigerella tomato
- 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 tigerella tomato 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 tigerella tomato 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 tigerella tomato
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.
Fertilising tigerella tomato — frequently asked questions
What fertiliser does tigerella tomato need?

What does over-feeding tigerella tomato 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 tigerella tomato 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 tigerella tomato?
In containers, fertiliser salts build up fast — water tigerella tomato 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.
