About Weeping Japanese Larch

Larix kaempferi 'Pendula' · also called Pendulous Japanese Larch, Weeping Larch · flowering

Weeping Japanese Larch is a deciduous conifer with long, pendulous branches that cascade dramatically from a trained central leader. In spring, soft, bright green needles emerge; in autumn they turn golden before dropping. This sculptural specimen is ideal for large gardens. It is not listed as toxic by the ASPCA.

Plant type: flowering

The reasons weeping japanese larch isn't blooming

Almost every non-blooming weeping japanese larch 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 weeping japanese larch 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 weeping japanese larch to flower

Maximise sun. Give weeping japanese larch 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 weeping japanese larch and get the feeding right with the weeping japanese larch 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

Weeping Japanese Larch 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 weeping japanese larch care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.

Why won't my weeping japanese larch flower?

Weeping Japanese Larch 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.

How do I make weeping japanese larch bloom?
