What fertiliser gold heart bleeding heart actually wants — and why
Gold Heart Bleeding Heart flowers best on poor soil — feed it and you get a lush leafy plant with very few blooms, the exact opposite of what you want.
Little or nothing. Rich, especially nitrogen-rich, soil pushes foliage at the expense of flowers in this plant — lean ground is the technique, not a deficiency.
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 gold heart bleeding heart: 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 gold heart bleeding heart, 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 gold heart bleeding heart:
Apply a balanced slow-release granular fertiliser (10-10-10) or top-dress with compost in early spring as shoots emerge. Avoid high-nitrogen feeds, which push leafy growth at the expense of flowers. In practice: no routine feeding at all for gold heart bleeding heart — at most a thin compost mulch for soil structure, never a flowering or nitrogen feed.
The dormant-season rule matters more than the exact interval: skip feeding entirely when gold heart bleeding heart 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 gold heart bleeding heart
