What causes Blue Arrow Juniper to turn brown?

There are several reasons why your Blue Arrow Juniper might be turning brown. One common cause is spider mites, which can cause the needles to turn brown and fall off. Another common cause is overwatering, which can lead to root rot and other fungal diseases. In some cases, the tree may simply be getting too much sun or not enough water.
To prevent your Blue Arrow Juniper from turning brown, make sure to keep it well-watered but not overwatered. Also, make sure to provide it with plenty of shade during the hottest parts of the day. If you suspect that your tree has a fungal infection or spider mites, you may need to use a fungicide or pesticide to treat the problem.

How often should Blue Arrow Juniper be watered?

Blue Arrow Junipers are relatively drought-tolerant, but they still need to be watered regularly. During the summer months, you should water your tree at least once a week, and possibly more often if the weather is particularly hot and dry. During the winter months, you can reduce the frequency of watering to once every two to three weeks.
When watering your Blue Arrow Juniper, make sure to give it a deep watering, so that the water reaches the roots. You should also make sure to water the tree early in the morning or late in the evening, when the sun is not as strong.

What is the best time to prune Blue Arrow Juniper?

The best time to prune your Blue Arrow Juniper is in the early spring, just before new growth begins. This will give the tree plenty of time to recover from the pruning before the hot summer months arrive. When pruning your tree, make sure to use clean, sharp pruning shears to avoid damaging the branches.
When pruning your Blue Arrow Juniper, focus on removing any dead or damaged branches, as well as any branches that are crossing or rubbing against each other. You should also thin out the tree by removing some of the interior branches, which will help to improve air circulation and reduce the risk of fungal infections.


In summary, the Blue Arrow Juniper is a stunning and hardy tree that can add a touch of elegance to any garden. But like any plant, it’s important to be aware of common problems and take action to prevent them.
