Cucumber Transplant Shock: Reasons, Symptoms, and Solutions
Are your cucumbers wilting?
If you're a gardener, then you know that transplant shock can be a real issue when moving plants from one location to another. This is especially true when growing cucumbers, which are notorious for experiencing transplant shock. There are many reasons why your cucumber plants might experience transplant shock, including not hardening off, damage to roots during transplant, under watering, overwatering, over-fertilizing, and diseases and pests. In this blog post, we will discuss the symptoms of cucumber transplant shock and the solutions that you can use to help your plants recover.

Signs of Cucumber Transplant Shock
Some signs that could signal that your cucumber plant is experiencing transplant shock are:
The leaves of the cucumber plant are turning yellow or brown
Wilting leaves
Leaf curling or rolling
The plant stops growing
New leaves that grow on the plant are small and stunted.
If you see any of these signs, then it's important to take action quickly in order to help your plant recover.
Cucumber Transplant Shock Causes
Unfortunately, cucumbers are very vulnerable to transplant shock. This is due to a number of different reasons, including:
Not Hardening-off
One of the most common reasons why cucumber plants experience transplant shock is because they haven't been properly hardened off before being transplanted.
When you transplanted your cucumber seedlings, did you harden them off first? If not, then this could be the reason for their transplant shock.
Hardening off simply means slowly acclimating your plants to the outdoors by increasing their exposure to the elements over a period of days or weeks so that they can become used to the new environment.
Cucumbers grown inside haven't experienced the wind, rain, or sun that they will be exposed to outdoors, so it's important to give them time to adjust. The climate and temperature change can be too much for them to handle all at once, which is why transplant shock often occurs.
If you don't harden off your plants first, then cucumber transplant shock is more likely to happen when moving this fragile young plant to the outdoors.
You can avoid this by hardening off your cucumber plants before transplanting them into the garden. Cucumbers that have been started from seeds indoors should be gradually exposed to the outdoor environment over a period of about seven days. Start by putting them outside in the morning for a few hours, then bring them back inside at night. Gradually increase the amount of time they spend outdoors each day until they are spending all day outside. Do this for about a week or two before transplanting them into the garden.
You can also harden off your cucumber by using a cold frame or greenhouse to protect them from the elements. When the nights are still chilly early in the season, an enclosure like a greenhouse will keep your plants warmer until it is ready for the growing season.
By the time you transplant your cucumbers, they will be much more acclimated to their new environment and will be less likely to experience transplant shock.
It is essential to harden off your cucumber plants before transplanting them into the garden.
Root Damage During Transplant
Another common reason why cucumbers experience transplant shock is because they sustain damage to their roots during transplant.
When you move a plant, its fragile roots can easily be damaged, be sure to handle them gently and avoid damaging the root ball when removing it from its container.
Don't shake off any dirt from the roots when you are transplanting your cucumbers. This can further damage their delicate root system.
Try using peat pots, which are biodegradable pots made out of paper that you can plant directly in the ground. This will minimize root disturbance when transplanting and help your cucumber plants to recover more quickly.
Also make sure that your seedlings aren't root-bound, or crowded in their small pot. Cucumbers that are root-bound will have a difficult time adjusting to their new environment and are more likely to experience transplant shock. To avoid roots that get tangled you can thin out your seedlings, leaving the strongest and healthiest plants to grow.
It is also important to make sure that you inspect the vines of your cucumber plants for any visible damage. If the cucumber vine is wilted or discolored, this could be a sign of root damage and your plant is more likely to experience transplant shock.

Cucumber plants that are wilting from damage.
Here are healthy cucumber plants.
Under Watering
If you don't water your cucumber plants enough after transplant, they will experience transplant shock.
Cucumbers need plenty of water to adjust to their new environment and without it, they can become stressed and succumb to transplant shock. Underwatered cucumber leaves will wilt and dry out and the plant will eventually die.
When planting cucumbers make sure to regularly water (but not overly) after transplant and they should recover quickly.
Over Watering
On the other hand, if you water your cucumber plants too much after transplant, they can also experience transplant shock.
Excess water can cause the roots to rot and the plant to wilt. When the roots are waterlogged, they can't uptake water and nutrients properly, which will eventually kill the plant. They are also more likely to get diseases when they are overwatered.
Make sure that you only water your cucumber plants when the soil is dry to the touch. If you're not sure, it's better to err on the side of underwatering rather than overwatering.
Over Fertilizing
Another common reason for cucumber transplant shock is over-fertilization.
Cucumbers don't need a lot of fertilizer and too much can actually be harmful to them. It can actually burn their roots and leaves, causing them to wilt and die.
When transplanting, it's best to use a light hand with the fertilizer.
When you do fertilize make sure it is a slow-release fertilizer that will break down gradually over time. This will prevent your cucumber plants from getting damaged.

Pests and Diseases
Cucumbers are also susceptible to pests and diseases, which can cause them to experience transplant shock.
Common cucumber pests include squash vine borer and the squash bug. These pests can damage the roots and leaves of your cucumber plants, causing them to wilt and die.
The squash vine borer will burrow into the cucumber stem, devouring it from the inside out. They feed on plant tissues and prevent water and nutrients from circulating throughout the plant as they consume its interior.
The squash bug drains the sap from the leaves' interior, causing significant damage to young plants and cucumber seedlings.
The insects' feeding spots are identified by the presence of dark brown or black spots. The leaves of the plant begin to droop as well.
Unfortunately once the cucumber is infested with these pests, there is little that can be done. The best prevention is to start with healthy plants and to keep an eye out for any signs of pests.
Cucumbers are also susceptible to diseases like bacterial wilt. Bacterial wilt is a serious cucumber disease that is spread by insects like cucumber beetles. The bacteria enter the plant through the wounds caused by the insect and clogs up the vascular system, preventing water and nutrients from circulating. This eventually kills the plant.
Bacterial wilt is difficult to control and often results in complete crop loss. The best prevention is to start with healthy plants and to control the cucumber beetle population.
It is important to monitor your cucumber plant closely for any signs of pests or plant disease and take action immediately if you see anything wrong. By being proactive, you can help prevent your cucumber plants from experiencing transplant shock.
Tips for a Successful Cucumber Transplant:
-Start with a healthy cucumber seedling and have developed at least 2-3 true leaves.
-Try using a peat pot that can go directly into the garden soil (less disruption to the roots).
-Harden off your cucumber plants for a week before transplanting them into the vegetable garden.
-Planting seedlings 12 inches apart allows them to have enough room to grow.
-Transplant on a cloudy day or in the evening to avoid scorching the leaves.
-Wait till the threat of frost has passed in your Zone and the soil temperature is at least above 60 degrees Fahrenheit.
-Choose a cucumber seed that is a cold-tolerant cucumber variety like Socrates, Wisconsin, or Corinto.
-Water your cucumber plants immediately after transplanting and keep the soil moist but not wet.
