About Mulberry Wine prickly heath

Gaultheria mucronata 'Mulberry Wine' · also called Mulberry Wine prickly heath, Mulberry Wine pernettya · flowering

A female cultivar of prickly heath selected for its exceptionally large, deep magenta-purple berries that persist well into winter, deepening in colour with age. Small, spine-tipped, glossy dark green leaves and tiny white bell flowers precede the fruit. Requires a nearby male plant to set berries. Best in acidic soil; excellent in containers. Toxic if ingested.

Plant type: flowering

The reasons mulberry wine prickly heath isn't blooming

Almost every non-blooming mulberry wine prickly heath 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 mulberry wine prickly heath 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 mulberry wine prickly heath to flower

  1. Maximise sun. Give mulberry wine prickly heath 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 mulberry wine prickly heath and get the feeding right with the mulberry wine prickly heath 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

Mulberry Wine prickly heath flowers across its growing season (mostly summer) and, kept fed and deadheaded, can bloom for many weeks or right up to frost.

Post-bloom care so it flowers again

Deadhead, keep feeding lightly, and many will rebloom; collect seed from the best plants at the end of the season if you want to grow them again.
