About Bloodgood Japanese Maple
Acer palmatum 'Bloodgood' · also called Bloodgood Maple, Japanese Maple · flowering
Bloodgood Japanese Maple is one of the most popular ornamental trees, valued for its deep burgundy-red foliage throughout the growing season and brilliant crimson autumn colour. A slow-growing, elegant small tree ideal for containers, courtyards, and mixed borders. Not listed as toxic to pets by the ASPCA.
Growth habit: Upright to broadly spreading deciduous small tree
What fertiliser bloodgood japanese maple actually wants — and why
Bloodgood Japanese Maple 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 bloodgood japanese maple: 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 bloodgood japanese maple, 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 bloodgood japanese maple:
Apply a slow-release balanced fertiliser (e.g., Osmocote) in early spring as buds break. Avoid high-nitrogen feeds in late summer, which promote soft growth susceptible to frost damage. A potassium-rich autumn feed supports next year's colour. 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 bloodgood japanese maple 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 bloodgood japanese maple
Half strength is the safe default for bloodgood japanese maple — 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 bloodgood japanese maple first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the bloodgood japanese maple watering schedule.
Signs you are over-feeding bloodgood japanese maple
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for bloodgood japanese maple:
- 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 bloodgood japanese maple
- 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 bloodgood japanese maple care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush the pot of bloodgood japanese maple 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 bloodgood japanese maple
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.
