About Miquel's Cycad
Macrozamia miquelii · also called Miquel's Cycad, Miquelii Macrozamia · tropical
Miquel's Cycad is a medium-sized Australian cycad from Queensland's coastal lowlands and tablelands. It produces a compact crown of stiff, dark green pinnate fronds from a short trunk and tolerates dry periods well. An excellent choice for subtropical gardens or large containers in full sun. Severely toxic to all animals and humans.
Growth habit: Medium-sized cycad with a stout, often low trunk and a terminal crown of stiff, arching dark green pinnate fronds; forms a hemispherical crown at maturity.
What fertiliser miquel's cycad actually wants — and why
Miquel's Cycad 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 miquel's cycad: 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 miquel's cycad, 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 miquel's cycad:
Apply a slow-release cycad-specific or palm fertiliser (8-2-12 or similar, low nitrogen) once in spring. Excess nitrogen encourages lush growth susceptible to insect damage. A supplemental micronutrient application in summer addresses magnesium and manganese needs. 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 miquel's cycad 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 miquel's cycad
Half strength is the safe default for miquel's cycad — 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 miquel's cycad first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the miquel's cycad watering schedule.
Signs you are over-feeding miquel's cycad
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for miquel's cycad:
- 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 miquel's cycad
- 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 miquel's cycad 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 miquel's cycad
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 miquel's cycad 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 miquel's cycad?
Flush the pot of miquel's cycad 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.
