About Chrysanthemum 'Ruby Mound'

Chrysanthemum 'Ruby Mound' · also called Ruby Mound mum, garden chrysanthemum · flowering

A compact garden chrysanthemum bearing rich ruby-red double blooms in late summer and autumn. It forms a neat mounded habit and thrives in full sun with well-drained soil. Toxic to cats, dogs, and horses due to pyrethrin compounds; keep pets away. Deadhead spent flowers to extend the display.

Plant type: flowering

The reasons chrysanthemum 'ruby mound' isn't blooming

Almost every non-blooming chrysanthemum 'ruby mound' traces back to one of these, roughly in order of how common they are:

  1. Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.
  2. Too much nitrogen feed, driving lush foliage at the expense of flowers (very common with general or lawn feeds).
  3. The plant has not been deadheaded, so it stops flowering once it sets seed.
  4. Irregular watering — drought or waterlogging at the budding stage makes buds abort.
  5. It is still too young or was checked by a transplant and is rebuilding before flowering.

Feeding chrysanthemum 'ruby mound' a high-nitrogen general feed and growing it in too little sun — you get a big leafy plant and almost no flowers.

The fix — how to get chrysanthemum 'ruby mound' to flower

  1. Maximise sun. Give chrysanthemum 'ruby mound' the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers.
  2. Switch the feed. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
  3. Deadhead regularly. Remove spent flowers often to keep it producing more rather than stopping to set seed.
  4. Water consistently. Keep moisture even through budding and flowering — drought-then-flood swings make buds drop.

Light and feeding do most of the heavy lifting here. Dial in the spot with the light guide for chrysanthemum 'ruby mound' and get the feeding right with the chrysanthemum 'ruby mound' fertilising schedule — the wrong feed (too much nitrogen) is one of the most common silent reasons a healthy plant makes leaves instead of flowers.

Bloom season and what to expect

Post-bloom care so it flowers again
