About Cymbidium tracyanum

Cymbidium tracyanum · also called Tracy's Cymbidium · flowering

Cymbidium tracyanum is a large, robust species cymbidium that produces long arching spikes of big fragrant flowers in greenish-yellow striped and spotted with red-brown, blooming in autumn and early winter. A vigorous semi-epiphyte with strap leaves and stout pseudobulbs, it needs bright light and cool autumn nights to flower well.

Plant type: flowering

Watch for — No flower spikes: The classic Cymbidium failure, from too little light or no cool autumn nights. Give maximum light and a 10-15°C night drop in early autumn to set spikes.

The reasons cymbidium tracyanum isn't blooming

Almost every non-blooming cymbidium tracyanum 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 cymbidium tracyanum 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 cymbidium tracyanum to flower

  1. Maximise sun. Give cymbidium tracyanum 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 cymbidium tracyanum and get the feeding right with the cymbidium tracyanum 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

Cymbidium tracyanum 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.

For everything else this plant needs day to day, see the full cymbidium tracyanum care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.

Cymbidium tracyanum blooming — frequently asked questions

Why won't my cymbidium tracyanum flower?

Cymbidium tracyanum blooms on the season's growth given enough sun, warmth and the right feed — there is no cold or photoperiod trick, just good growing conditions and a bloom-leaning feed. The most common reason it is not happening: Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.

How do I make cymbidium tracyanum bloom?

Give cymbidium tracyanum the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.

When does cymbidium tracyanum normally bloom?

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

What should I do with cymbidium tracyanum after it flowers?

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.

What is the single biggest mistake stopping cymbidium tracyanum flowering?

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