What to Do With Ligustrum Bushes in Transplant Shock?

I have ligustrum bushes that were transplanted in by backyard this September. Since then they look really sick! They have lost most of there leaves. However, the wood is still green when you break a limb off. How can I help them or should I replace them?

At this point in time, it is likely not transplant shock. That normally occurs within a few weeks of transplanting.

It may be underwatering. This winter has been odd in many parts of the world. Newly planted shrubs need plenty of water the first year to establish themselves. If it was a dry winter where you are or if it was a warm winter with average rainfall, the shrubs may not be getting the water they need to help establish themselves. I would recommend increasing water to the plants and water them regularly until you see the leaves start to regrow.

What Is the Best Way to Treat Brown Spots on Ligustrum Leaves?

It is spreading across 6 shrubs alongside of our driveway.

Thanks!

This is likely due to a fungus. Neem oil is an effective fungicide.

Fungus

I have some ligustrum and red tip photinia shrubs that are at least 15 to 20 years old. Last year they caught a fungus and most of the leaves fell off. I used Martin’s Honor Guard and brought them back…a little. They are starting to show small new leaves on the outer surfaces but the core of the plant has no leaves; all you see are sticks. They stand about 45″ high. Should I pull them and start over or trim them down to 36″ or less and wait for nature or leave them alone and see what happens?

I would prune them back and let the new growth take over from there, though I wouldn't take more than a third of their growth.

New Privet Hedge

I planted a row of 29 small privet hedge plants (about 20-25 inches tall) in my front garden in February. They looked like dead sticks when I planted them. It’s now late May and some are now starting to show signs of life; however, there is only green shoots on 6 out of the 29 so far. The other 23 still look like dead sticks. I am looking after them well and the ones showing green shoots are not all in one spot – they are spread out. Will the remaining 23 come to life eventually or are they goners?

What to Do for a Dying Ligustrum Hedge?

My ligustrum hedge is thinning (badly) and now has brown leaves. I suppose it is dying. I have invested several thousand dollars in this hedge, as I need this for privacy, unfortunately. Any suggestions would be greatly appreciated. I live in Urbanna, VA – about 60 miles east of Richmond in a section called the Tidewater. I am about 5 miles away from the Rappahannock River.

How old is the hedge? Has the hedge been in gradual decline for quite some time or did this just happen after winter? If it is the latter, then your shrub probably sustained some cold damage. For more information on cold injury and a prescribed course of treatment, please visit the following link:

Is there anything unusual that you can see on the leaves or branches - any signs of disease or fungus or even an insect infestation?

If the hedge's decline isn't due to winter injury then you may want to consider pruning it back hard in order to bring back new life. However, that would mean losing your privacy for awhile but it might salvage your monetary investment.

Sick Ligustrum

I have a sick ligustrum. Can you help? I have never seen this before. The plant is covered in brown pod like things at the point where all new growth should come out. After a while new leaves come out of the pod but are very small and then die. The plant was cut back at the same time the rest of the hedge was cut in spring, but it has never come back like the others. It looks like sticks with brown pods all over it.

It's difficult to say exactly what is effecting the shrubs, but they can be susceptible to fungus. Rake and remove any leaves that have dropped off of the plants.
Treat the shrubs with Neem Oil as this both works as a fungicide and pesticide.
Have you had heavy rain? If the plants are heavily mulched you can pull back the mulch to help dry out the soil.

Cercospora

Ligustrum covered with Cercospora. About a dozen 5′ high. I am considering using hedge trimmers to cut the growth containing this fungus then cleaning up the area under the plants before spraying with fungicide. Also fertilizing.
Is this the right approach?

This can be a difficult fungus to treat, though the link below has some specific chemical treatment.
