About Antirrhinum majus 'Twinny Peach'
Antirrhinum majus 'Twinny Peach' · also called Twinny Peach Snapdragon, Double Peach Snapdragon · flowering
A dwarf, double-flowered snapdragon and All-America Selections winner, 'Twinny Peach' bears soft peach, apricot, and cream open-faced double blooms on compact, well-branched plants. Bred for heat tolerance and tidy bedding, it suits borders, containers, and the front of beds. It flowers prolifically in cool-to-mild weather and needs no staking.
Growth habit: Compact, bushy, freely branching dwarf snapdragon producing short spikes of fully double, open-faced flowers across a neat mound.
Watch for — Aphids on new growth: Soft clusters on buds and tips. Rinse off with water or apply insecticidal soap, and avoid over-fertilising, which produces aphid-attracting soft growth.
What fertiliser antirrhinum majus 'twinny peach' actually wants — and why
Antirrhinum majus 'Twinny Peach' 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 antirrhinum majus 'twinny peach': 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 antirrhinum majus 'twinny peach', 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 antirrhinum majus 'twinny peach':
Feed container plants every 2 weeks with a balanced liquid fertiliser; in beds, feed every 3-4 weeks or use slow-release granules at planting. Regular feeding sustains the heavy double-flower display through the season. Treat that as every 2 weeks 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 antirrhinum majus 'twinny peach' 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 antirrhinum majus 'twinny peach'
Half strength is the safe default for antirrhinum majus 'twinny peach' — 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 antirrhinum majus 'twinny peach' first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the antirrhinum majus 'twinny peach' watering schedule.
Signs you are over-feeding antirrhinum majus 'twinny peach'
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for antirrhinum majus 'twinny peach':
- 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 antirrhinum majus 'twinny peach'
- 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 antirrhinum majus 'twinny peach' care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush the pot of antirrhinum majus 'twinny peach' 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 antirrhinum majus 'twinny peach'
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.
