About Agastache 'Kudos Coral'

Agastache 'Kudos Coral' · also called Kudos Coral hummingbird mint · flowering

Agastache 'Kudos Coral' is a compact, dwarf hummingbird mint bred for dense coral-peach flower spikes from midsummer into autumn. It thrives in full sun and sharp drainage, drawing bees, butterflies and hummingbirds while shrugging off heat and drought. Aromatic minty foliage deters deer and rabbits. Short-lived but reliably perennial in well-drained, lean soils.

Growth habit: Compact, bushy, upright clump-forming perennial with densely branched stems topped by short flower spikes; far tidier and more uniform than older, taller hummingbird mints.

What fertiliser agastache 'kudos coral' actually wants — and why

Agastache 'Kudos Coral' 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 agastache 'kudos coral': 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 agastache 'kudos coral', 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 agastache 'kudos coral':

Feed sparingly. A single light application of balanced slow-release fertiliser in spring is plenty; rich feeding produces lush, weak growth that flops and flowers poorly. No feeding needed in lean soils. 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 agastache 'kudos coral' 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 agastache 'kudos coral'

Half strength is the safe default for agastache 'kudos coral' — 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 agastache 'kudos coral' first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the agastache 'kudos coral' watering schedule.

Signs you are over-feeding agastache 'kudos coral'

Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for agastache 'kudos coral':

If the symptoms point at watering, light or roots rather than nutrition, the full agastache 'kudos coral' care brief covers soil, humidity and the common problems for this species.

Flushing and leaching the salts

Flush the pot of agastache 'kudos coral' 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 agastache 'kudos coral'

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.

Half strength is the safe default for agastache 'kudos coral' — houseplant feeds are formulated strong, and the diluted dose is gentler on the roots while still ample for foliage.

What does over-feeding agastache 'kudos coral' 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 agastache 'kudos coral' 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 agastache 'kudos coral'?

Flush the pot of agastache 'kudos coral' 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.
