About Wisteria 'Amethyst Falls'

Wisteria frutescens 'Amethyst Falls' · also called Amethyst Falls wisteria, American wisteria · flowering

Wisteria frutescens 'Amethyst Falls' is a compact, well-behaved American wisteria with short racemes of lilac-blue scented flowers. Less rampant than Asian wisterias, it blooms young, often reflowers in summer, and suits smaller gardens, arches and containers. Grow it in full sun on fertile, well-drained soil with sturdy support.

Plant type: flowering

Watch for — All leaves, no flowers: Usually caused by too much nitrogen, too much shade or lack of summer pruning. Use a high-potassium feed, full sun, and prune in summer and winter.

The reasons wisteria 'amethyst falls' isn't blooming

Almost every non-blooming wisteria 'amethyst falls' 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 wisteria 'amethyst falls' 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 wisteria 'amethyst falls' to flower

Maximise sun. Give wisteria 'amethyst falls' 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 wisteria 'amethyst falls' and get the feeding right with the wisteria 'amethyst falls' 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

Wisteria 'Amethyst Falls' 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.
