About Crippsii Hinoki Cypress

Chamaecyparis obtusa 'Crippsii' · also called Cripps Golden Hinoki Cypress, Golden Hinoki Cypress · flowering

One of the finest golden Hinoki cypresses, 'Crippsii' forms a loose, broadly conical specimen with arching sprays of bright golden-yellow new growth fading to greenish-gold within. Moderate in vigour, it makes a glowing focal point. Full sun maximises the gold; it needs moist, well-drained, slightly acidic soil and cool, humid conditions to look its best.

Plant type: flowering

The reasons crippsii hinoki cypress isn't blooming

Almost every non-blooming crippsii hinoki cypress traces back to one of these, roughly in order of how common they are:

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

Feeding crippsii hinoki cypress 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 crippsii hinoki cypress to flower

Maximise sun. Give crippsii hinoki cypress the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers.
Switch the feed. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
Deadhead regularly. Remove spent flowers often to keep it producing more rather than stopping to set seed.
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 crippsii hinoki cypress and get the feeding right with the crippsii hinoki cypress 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

Crippsii Hinoki Cypress 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.
