If your plants are dying either through drought or lack of attention then there are ways to save them.
First you need to be familiar with the watering and sunshine requirements for your plant; every plant has its own way it needs to be nurtured.
Dying plants are not thriving because they are not getting enough nutrients they need or are not getting enough sunlight or water.
Sometimes planters go overboard by watering too much. Dying plants that are in pots may need larger pots, especially ones that are growing. Be sure to water and make sure the soil is absorbing the water. If your water leaves a pool then drain accordingly. In the case of dying plants, as much water possible needs to get to the root. If your plant is suffering from wilted or yellow leafing then most likely you are watering too much. If your plants are in a pot then be sure to check the soil with your fingers. If your soil is too watery or muddy then you are over watering, and if it feels sandy or too dry to the touch then your plant needs more water quickly. Plants appreciate sunlight, but some plants cannot thrive as well in direct sunlight, especially during the growing period. For dying plants, be sure to balance how much sun your plant is getting by placing it outside for a few hours of sunlight then taking it back inside. Place dying plants by a window sill so they can get the satisfaction of direct sunlight while not being outside. If you’re caught in a season like winter or are constantly bombarded by rainy weather then try artificial lighting, but make sure you know the proper wattage so your plant can get the proper dosage of lighting.
Another problem that many gardeners overlook is the soil. Plants in general need a good balance of nitrogen and potassium for overall plant and root growth. If you do not know what your PH level in the soil is be sure to check with your local nursery or simply purchase organic soil to help your plants out. There are even mail-in soil test samples you can use to find out what kind of soil is needed to nurture a particular plant. Always buy organic soil since they contain the most nutrients that will help plants thrive. Fertilizer is a good way to nurture soil and attract positive microbes to make the soil healthier. Use compost and mulch to retain extra moisture for dying plants.
If your plants are showing signs of struggle then it is not the end of the world, and plants that are not doing as well can be saved. When trying to preserve dying plants, be familiar with the plants you grow and make sure you follow step by step plans to save the plants you love growing. When it comes to dying plants, it is most likely a simple step that the gardeners may have overlooked when nurturing a plant.
