About Weeping silver pear
Pyrus salicifolia 'Pendula' · also called Weeping silver pear, willow-leaved pear · flowering
An elegant small deciduous tree producing long, narrow, willow-like leaves covered in silver-white down that glistens in sunlight. Creamy-white flowers appear in spring, followed by small, hard, inedible fruits. The gracefully weeping habit makes it a sculptural focal point for borders and formal gardens. AGM holder; drought-tolerant once established.
Growth habit: Small deciduous weeping tree; grafted standard form common
Watch for — Fireblight (Erwinia amylovora): Blossom and shoot blight causing blackened, wilted branch tips. Prune 30–45 cm below visible infection with sterilised tools; warm, wet spring conditions increase risk. Avoid high-nitrogen feeds.
What fertiliser weeping silver pear actually wants — and why
Weeping silver pear 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 weeping silver pear: 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 weeping silver pear, 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 weeping silver pear:
Young trees benefit from a balanced fertiliser in early spring for the first 2–3 years. Established trees rarely need feeding; excess nitrogen produces soft growth susceptible to fireblight and reduces the silver leaf quality. 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 weeping silver pear 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 weeping silver pear
Half strength is the safe default for weeping silver pear — 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 weeping silver pear first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the weeping silver pear watering schedule.
Signs you are over-feeding weeping silver pear
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for weeping silver pear:
- 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 weeping silver pear
- 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 weeping silver pear care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush the pot of weeping silver pear 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 weeping silver pear
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.

What does over-feeding weeping silver pear 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 weeping silver pear 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 weeping silver pear?
Flush the pot of weeping silver pear 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.
