About Southern Magnolia 'Little Gem'

Magnolia grandiflora 'Little Gem' · also called Little Gem Magnolia · flowering

'Little Gem' is a compact, columnar form of the evergreen Southern magnolia. It carries glossy dark leaves with cinnamon-felted undersides and produces large, fragrant white cup-shaped flowers from late spring through summer and sporadically into autumn. Far smaller than the species, it suits courtyards, screens, and large containers in warm-temperate gardens.

Plant type: flowering

The reasons southern magnolia 'little gem' isn't blooming

Almost every non-blooming southern magnolia 'little gem' 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 southern magnolia 'little gem' 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 southern magnolia 'little gem' to flower

  1. Maximise sun. Give southern magnolia 'little gem' 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 southern magnolia 'little gem' and get the feeding right with the southern magnolia 'little gem' fertilising schedule — the wrong feed (too much nitrogen) is one of the most common silent reasons a healthy plant makes leaves instead of flowers.
