Symptoms of Transplant Shock
Dying leaves, even in the spring and summer, can sometimes be found on stressed trees after planting. Discoloration of needles in evergreens is a sign of stress. The ends of the needles turn brown and eventually die if the tree continues to be stressed.
Most trees will survive transplant shock and some will rebound quickly in one month to 6 weeks, while others may need a dormant period to completely recover. To prevent transplant shock in the future (aside from time of year), consider planting on a cool cloudy day, when rain is forecasted in the next 24 hours.
Dead trees and trees in shock can look deceivingly similar, but there's an easy way to tell the difference. Pick a random twig on the tree and scratch it with your finger or a pocket knife. Do the same for a few other twigs throughout the tree. If they're all bright green and moist underneath, viola!
Symptoms of Transplant Shock
The plant may appear limp and droopy. Leaf yellowing: The leaves may turn yellow or even brown, especially at the edges or tips. This can be a sign of nutrient deficiency or reduced water uptake. Leaf drop: The plant may shed leaves as a response to the stress.
In time, the plants usually recover. You will see new growth and a greening up of the leaves.
General discomfort, uneasiness, or ill feeling. Pain or swelling in the area of the organ (rare) Fever (rare) Flu-like symptoms, including chills, body aches, nausea, cough, and shortness of breath.
Determining if a tree is dead in the winter is a little bit more difficult because dormant trees can look just like a dead tree. One thing you can look for however is if the tree has buds on the branches. Even in the winter time a tree should show signs of buds.
Fertilization at the time of planting is generally not recommended. It is ineffective until the root system has a chance to reestablish. It is usually advisable to wait two or three years before applying fertilizer, and then it is recommended to get a soil test first.
Newly planted trees or shrubs require more frequent watering than established trees and shrubs. They should be watered at planting time and at these intervals: 1-2 weeks after planting, water daily. 3-12 weeks after planting, water every 2 to 3 days.
We recommend soaking the root ball slowly with your garden hose, gradually moving the hose around the perimeter of the tree. In addition to soaking the root ball, water the area around the edge of the tree well to encourage outward root growth.
Mix in one tablespoon of Epsom salt into the soil in the hole just before you plant. Additionally, you can mix one to two tablespoons per 3-4 litres of water and use it to water fresh transplants. If you have a lot of new transplants, then work to a ratio of 5 gram per square metre.
These symptoms often occur shortly after a plant is transplanted, but there are also long-term effects that you may only notice months or years after the initial shock. For example, plants that suffer from transplant shock will often fail to grow as vigorously as individuals who didn't suffer as much root damage.
The most common reasons for transplant shock and root stress are planting too deep, poor drainage, backfilling with composted soil amendments, damaging the stem/root ball connection during planting or excessive watering.
Other symptoms of transplant shock appear as wilting leaves (especially on recent transplants), yellowing, and leaf rolling or curling.
Sugar water does not do anything to help plants with transplant shock, and it can make it worse. Often, plants recover on their own. Just give them time, keep them well-watered, and protect them from too much sun to prevent more leaf scorch.
Be patient: If you treat your tree well, the tree should recover from shock and establish itself. It can take up to 3 years for a tree with transplant shock to fully recover.
Newly planted trees must remain hydrated, but it can be tricky knowing how to properly water them. One thing that should be avoided is over-watering the plant and making it soggy. You want to keep the root ball and soil surrounding it intact. The key is to provide the plant and soil with moisture without overdoing it.
It's normal for trees that have been recently transplanted to experience a period of transplant shock, and one of the telltale signs of this condition is brown leaves. You might be tempted to panic and start watering your tree more often, but this could cause other issues.
Having an episode of rejection can be discouraging, but remember that they are common. Most rejection episodes can be reversed if detected and treated early. Treatment for rejection is determined by severity.
Acute transplantation rejection is an immune response against the donor graft that causes tissue impairment and potential failure. [1] T-cell and antibody-mediated rejection are the primary mechanisms leading to acute transplantation rejection.
Acute rejection can occur at any time, but it is most common from one week to three months after transplant surgery. Fifteen percent or less of patients who receive a deceased donor kidney transplant will have an episode of acute rejection. When treated early, it is reversible in most cases.
