Got a green thumb and want to begin gardening, or have already begun planting and caring for a Magnolia tree? That’s awesome, considering that Magnolia trees are beautiful and majestic-looking, especially with their large and fragrant white blossoms.
However, you may come across a few problems, and one of the bigger ones is its demise. If you see some signs of it dying, of course, you would want to revive and save it to continue growing and looking amazing! But how can you do so?
Read on to see how to revive a dying Magnolia tree and if it’s possible to do so for your case!
How to Revive a Dying Magnolia Tree
The Southern magnolia, or the Magnolia grandiflora, is a perennial plant in the US, which is a hardy one that doesn’t stand much risk of pests or diseases. That’s why it’s so easy to care for and maintain, though there are still chances of it dying due to various reasons. These are the following reasons why, and what you can do to solve it:
1. Verticillium Wilt
This is a disease that would cause branches to die one by one, eventually killing magnolia trees. If you think that verticillium wilt is causing your magnolia tree to die, then you can first diagnose it by cutting off part of an affected branch (the width of your finger). Check for any vascular discoloration, or if your branch looks red or brown.
To remedy and prevent the spread of the wilt, prune out all the affected branches under the site of infection. When you prune, make sure to disinfect your shears between cuts, which will avoid spreading the disease. You can disinfect your shears by soaking them for five minutes, using a solution of one part 70% isopropyl alcohol and one part of water, drying the shears after you soak and before cutting.
2. Canker Diseases
Cankers would create dead and sunken patches on tree branches, which would cause the tree’s leaves to turn yellow or brown, then wilting away. Eventually, the tree branches and the tree would die.
You will know if ever there are cankers on your magnolia tree when you prune out a branch that’s below the site of disease. Make sure you use disinfected pruners to check.
But once you have cankers that seriously infect the tree trunk, you aren’t able to save the dying Magnolia tree. Furthermore, you will need to avoid planting any magnolias in the same spot anymore.
3. Root Rot
Root rot is caused by various soil pathogens. When it comes to magnolia trees, there are certain Phytophthora species to blame, including the cinnamomi, parasitics, cirtricola, cactorum, and the cryptogea.
One of the main causes is overwatering your tree, especially during warmer weather, as this causes pathogens to flourish and grow, invading the plant roots. As a result, plant roots are invaded, the leaves wilt, and branches die.
To avoid this from happening, do not overwater your magnolia tree and let your soil dry out between any irrigations. Furthermore, clean up all debris that falls around the tree base, as this also encourages pathogen growth.
4. Leaf Scorch
Magnolias are susceptible to the winter leaf scorch, which can also occur in warmer climates. While they don’t usually kill branches, it can burn your magnolia tree leaves, resulting in defoliation on the tree, whether one side or all over.
Winter lead scorch is more susceptible to magnolias that haven’t been protected by the drying winter winds, which would deplete the leaves of water quicker than when drawing it from the ground. This is especially true when living in an area where your grounds usually freeze over.
That’s why it’s best to plant your trees in areas where you can protect the trees. While drought-tolerant and can survive hot summers, they need moist soils and shouldn’t be exposed to freezing temperatures.
5. If There Is No Hope
You can inspect the tree further to see if there is still hope to revive it. Check its leaves first. Do you see leaves, if any at all? And if so, do they appear healthy or look stunted in a way?
If you see branches with leaves with some dying, then there is a disease. Examine its buds to see how they died, and if they are brown all throughout, they have been dead for a long time. You can also try to check out the cambium layer, below the bark’s outer layer, to check if it’s green, brown, or dead.
If you see branches with mostly green cambiums, you are able to revive it, and simply wait for a few months while properly caring for your magnolia tree. But if you see widespread cambium death, then there is no way to revive the tree anymore.
When you do choose to replace it, identify any changes that have been made around the area in terms of its growing conditions. This can help you figure out how to care for your next magnolia tree better. Also, when replacing it with a new tree, match the growing conditions to the tree’s requirements, and to ensure that the same thing won’t happen to the new tree.
