About Baby Tears (Pilea)
Pilea depressa · also called Baby Tears, Baby's Tears Pilea · houseplant
Pilea depressa, or Baby Tears, is a small trailing Urticaceae houseplant with masses of tiny round green leaves on creeping stems, ideal for terrariums and hanging pots. It wants bright indirect light, steadily moist soil, and high humidity. The ASPCA lists no Pilea as toxic, so it is considered pet-safe.
Growth habit: Low, spreading, trailing/creeping subshrub. Thin stems carry masses of tiny round leaves and cascade over pot edges or knit into a dense mat across soil, making it popular as ground cover in terrariums and in hanging or shelf displays.
What fertiliser baby tears (pilea) actually wants — and why
Baby Tears (Pilea) 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 baby tears (pilea): 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 baby tears (pilea), 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 baby tears (pilea):
Feed every 4-6 weeks during spring and summer with a balanced liquid houseplant fertiliser diluted to half strength. Stop feeding in autumn and winter while growth is dormant. This is a light feeder, so over-fertilising can burn the delicate roots and leaf tips. Treat that as every 4-6 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 baby tears (pilea) 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 baby tears (pilea)
Half strength is the safe default for baby tears (pilea) — 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 baby tears (pilea) first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the baby tears (pilea) watering schedule.
Signs you are over-feeding baby tears (pilea)
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for baby tears (pilea):
- 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 baby tears (pilea)
- 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.

Flushing and leaching the salts
Flush the pot of baby tears (pilea) 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 baby tears (pilea)
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.

Lower leaves yellow and drop while the soil is correctly watered. Feeding baby tears (pilea) 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 baby tears (pilea)?
Flush the pot of baby tears (pilea) 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.
