Japanese maple Bijou dead ends?

We planted our JM Bijou last summer and from the end of summer until now it developed these dead, woody ends on many of its branches (see photo). Some are only a couple inches long, some are longer. Should these just be snipped? Is there anything I should do to prevent it from happening again?

Probably winter damage.

RE: Japanese maple Bijou dead ends?

That's Bihou (not Bijou) and it could very well be winter dieback. But this cultivar is also extremely prone to Pseudomonas, which often presents as black twigs and stem tips. Sometimes pruning this out to clean wood will help but not always. Pseudomonas can become systemic in time and then untreatable. Eventually the tree will die.

If pruning, be sure to sterilize pruners between cuts to limit any potential for spreading diseases.

Combined experiences reported on the web are pointing already to this cultivar effectively being a mutt, due to the tip die-back.

I'm going to pull mine out, which has had dead ends since the first winter.

Pseudomonas infections often follow minor cold damage.

HAD one. "HAD" being the key word. Appears to be a beautiful but VERY weak cultivar. Took exactly two winters (mild at that) to die even with protection. Will not touch this one again.
