Can I Prune Back My Wisteria Now?

Hi,

I live in Harrisburg, PA. I never trimmed my wisteria during the winter (this is my first wisteria and I bought it last spring/summer). Right now there are dead wispy limbs all over the place. Wasn’t sure if I could trim those off.   I see no buds as of yet (I know it’s early), but I don’t want to take a chance in ruining it. Any advice would be most appreciated! Thanks so much!

Lisa

The flower buds of wisteria are produced during the summer (on last year’s wood), so wait until late spring or early summer to prune the vine. This article can help you with pruning: https://www.gardeningknowhow.com/ornamental/vines/wisteria/pruning-wisteria.htm

Thanks Nikki! Guess I have a bit to learn about the Wisteria plant. I'll make sure to prune twice a year. Have a great day! : )

What Is the Best Fertilizer for Wisteria?

What is the best fertilizer for wisteria?

Healthy vines don't need much in the way of fertilizer but should yours need some, I would recommend giving it a slow-release, water-soluble, balanced fertilizer.

Pruning and Care of Wisteria Vine

I bought a property with a wisteria vine on it. The host was a red oak. I didn’t know it was a wisteria and cut it about 4′ from the ground. It was a massive vine reaching 60′. Will it live and how do I care for it?

Wisteria can take pretty severe pruning, so it should be ok. As a matter of fact, one of the biggest complaints about wisteria is that it is so hard to get rid of.

Wisteria

My wisteria vine has never bloomed before. This year it has been very unseasonally warm. My wisteria has buds all over it. The problem is it is suppose to get below freezing the next couple nights. Is this going to hurt the buds from maturing into flowers? Is there anything I need to do to protect it?

ANSWERS

The freezing temps can indeed harm the buds, so you may need to cover the vine if at all feasible. This article will help: https://www.gardeningknowhow.com/plant-problems/environmental/protect-plants-in-freeze.htm

If Wisteria Poisonous to Cattle

I want to put a wisteria vine on a fence. I’m concerned that it might be something cattle would eat and be poisonous.

Yes, wisteria is poisonous, especially the pods. I would recommend planting it on a fence (or elsewhere) that is far enough back from the animals' reach.

Planting Wisteria

I live in N. J. and love wisteria plants. When is the best time to plant them? It is spring. Is it a good time to plant wisteria now or is it too late for them to bloom this year?

ANSWERS
Nikki

Late fall or early spring are the most ideal times for planting this vine, so yes, now would be the best time for you to plant it. Blooming will depend on several factors, though the following articles should help qith its care: https://www.gardeningknowhow.com/ornamental/vines/wisteria/growing-wisteria-proper-wisteria-vine-care.htm

Evergreen Wisteria

We just purchased a home and there is an evergreen wisteria growing on a trellis – it was not cut back in the fall and is starting to get out of control. Is it ok to cut this back even though it’s the start of spring?

ANSWERS

You are not to late to prune. In fact, the flowerbuds of wisteria are produced during the summer (on last year’s wood), so wait until late spring or early summer to prune the vine back. Pruning the previous year's growth too severely will remove the flower buds, but that is rarely the case. Most people do not prune severely enough. Severe pruning is often recommended, back to three or four buds, to keep the plant manageable and renewed.
