It may have had some impact on its roots during transportation or a drastic change in temperature, especially in a car that gets in the sun. It may also have been taken from the place of cultivation where its small roots expanded out of the planting pot or sachet into the ground, causing what is known as root bleed. Often when this happens, the plant takes about four weeks to recover and returns to live with some loss of branches and leaves.
The fact is that when cases like these occur, we wonder whether or not the little plant will resist, returning to vegetar.
To know if it is alive, even with dry branches, you need to make sure that the main branch is green inside. One way to find out is to do a little scratch on the woody fabric. It will reveal if there is a green fabric underneath.
In small trees, my recommendation is to make this scrape even with the nail, at the time of branch bifurcation and crown opening: if the woody tissue does not reveal a green underneath after scraping, lower it a little, at the trunk level. And take a new test. If there is still no sign of green tissue, head toward the base near the root. If there is nothing green, then yes, your little plant has died. If the tree is larger, look for fungus at the base of the trunk and the hollow sound as it hits the wood.
It is then up to you to decide what to do. You can reuse the pot to grow another plant, such as a beanstalk or a vine to tangle in the old dry trunk, or cut the stem and replant something in its place. If you are going to reuse the soil, take a look at the root of the dead plant, and see if there is any sign of insect or break in the clod to find out what happened. And before reusing the soil, let it dry in the sun completely and then recompose the pot.
But if after scraping the woody fabric reveals the green fabric, it will be a sign of life, and you can cut the dry parts to help regrowth when spring arrives.
An important tip at this time is to take care of the irrigation because, during this period of retraction of the branches, the plant is in vegetative rest ie, sleeping or hibernating, in most cases, because of winter. Watering should then decrease so as not to favor root rot, as the plant will asleep absorb less water.
This is also a good time to clean the trunk of small insects such as mealybugs and fertilize the soil. Spraying it with a solution of 60 drops per liter of mineral water and the Bach flower called Rescue can save it from this latency state, stimulating it to a new phase. So do not immediately conclude that you have no way of doing this… Plants hibernate regardless of our will, and there are three different types of developmental cycles.
Annuals that survive for a single season and after flowering produce seeds and die. Already those that come back to life only next season, through their seeds and bulbs and roots, are usually fast-growing plants and abundant flowering. Examples are amaryllis, lettuce, tagetes, sunflower, and dahlias, like this rose, which you see in the image below.
