- The DIY Network’s “Yard Crashers” anchor and “Early Show” contributor Ahmed Hassan provided these advice on air for maintaining the health and vitality of your indoor plants:
- Use the right soil.
- Water plants liberally.
- Eliminate Extra Water.
How can you maintain healthy, green plants?
When a plant contracts a disease, it’s one of the most mysterious things that may happen in your garden. How did it take place? Will it grow more? Will every plant I have die? How do I eliminate it? The illness triangle is a concept that is crucial to comprehending disease prevention (drawing, right). Three factors must come together for disease to occur: a susceptible plant (the host), an invading pathogen (such as a fungus, bacteria, or virus), and conducive environmental factors (such as humidity or drought). The disease cannot exist without any of these factors, so eliminating even one of them is necessary for prevention. Consider that the best defense against disease is a good attack rather than waiting for an issue to arise in your garden. The following 10 methods will help you maintain your plants healthy while removing at least one side of the disease triangle.
Examine plants carefully before buying
Avoiding the introduction of illness in the first place is the simplest strategy to reduce its impact on your garden. No one wants the added bonus of getting a disease with a new plant. Knowing what a healthy plant should look like is one of the hardest things to learn, making it challenging to determine whether the plant you desire is ill.
A few books, periodicals, and catalogs that display images of healthy specimens are a wonderful idea to gather. Avoid bringing home a plant that has insects, rotten stems, or dead patches. These issues are frequently challenging to eradicate once they become established and can readily spread to your healthy plants.
Always examine the quality of the roots of plants in addition to the crowns. Although it should be commonplace, one does not frequently observe customers doing this in a garden center. Put the plant stem in your fingers and place your hand on the earth. Gently invert the pot and shake the plant loose. To remove the roots from the pot, you might need to tap the pot’s edge on a hard surface. The root-ball should have firm, often white, evenly spaced roots. Not a good indicator are roots that are dark or spongy. It won’t be long before a plant with a rotten root system dies, even if the tops seem healthy.
Use fully composted yard waste
Not every component of a compost pile breaks down at the same rate. While certain materials may have deteriorated enough to be used in the garden, others may not have. Long-term high temperatures produced by thorough composting really eliminate any germs present in the material. Debris from infected plants that have not gone through this process will likely reintroduce diseases into your garden. Avoid utilizing yard trash as mulch around delicate plants and avoiding adding potentially infectious debris to your compost pile if you are unsure of the health of your pile.
Keep an eye on your bugs
Plant damage from insects goes far beyond mere aesthetics. Viruses and bacteria frequently require an opening of some kind in order to enter a plant, which bug damage gives. Viruses are really transported by some insects, who then pass them from one plant to the next. Thrips also transfer the impatiens necrotic spot virus, which has been a significant issue for commercial growers over the past ten years. Aphids are one of the virus’ most frequent carriers. Aster yellows (picture on the right) affects a wide variety of host plants and is spread by leafhoppers. Another factor that might stress out a plant and reduce its ability to resist disease is insect infestations.
Clean up in the fall
Even if you reside in a climate with mild temperatures, it is always better to clean up the garden in the fall. This is not only a wonderful approach to prevent sickness, but it’s also an excellent strategy to manage diseases that are currently present in your garden.
On dead leaves and other debris, diseases can overwinter and then attack new leaves when they sprout in the spring. If the fallen leaves are removed each fall, diseases like iris leaf spot, daylily leaf streak, and black spot on roses can be greatly diminished. If you are left stems and foliage to add interest throughout the winter, make sure to get rid of them before springtime new growth begins.
Apply the correct fertilizer
When fertilizing plants, you must exercise caution because too much of any fertilizer will burn roots, decreasing their capacity to absorb water. The plants are consequently more vulnerable to drought, cold, and heat stress. A healthier plant can fend off illnesses, whereas nutrient-starved plants are smaller and are more susceptible to leaf spots. Another approach to stress out a plant is to have too much of a certain nutrient.
Your local extension office may do a soil test to provide you precise information on the nutrient levels in your soil. Without it, you would likely have to rely on guesswork when feeding your plants, which could lead to too much of one nutrient or not enough of another.
Plant disease-resistant varieties
Plants that are disease-resistant are those that could contract a specific ailment but will resist it rather than dying from it. For instance, certain tomato varieties are designated as “VFN resistant,” meaning they are resistant to nematodes as well as the fungus Verticillium and Fusarium.
You might be let down if you start hunting for these codes on flowers because disease resistance is rarely noted on plant tags. This does not imply that all flower cultivars lack disease resistance. Many rose growers offer plants that are resistant to maladies like black spot and powdery mildew.
You can get assistance identifying the best or most resilient varieties of many plants from nursery workers and other gardeners. Additionally, plants and types that are resistant to specific diseases may be listed in reference books and catalogs.
Prune damaged limbs at the right time
It is preferable to trim trees and shrubs in the late winter as opposed to the spring. Infected limbs can spread illness over the winter, which will allow it to spread while the plant is dormant. Pruning in the late winter stops illness from spreading to new growth. Even though late-winter storms can result in more damage, it is still preferable to remove a damaged limb now rather than waiting until spring to do so. Always make clean, quick cuts with sharp equipment, and make sure you only remove healthy, living tissue.
Choose and site plants appropriately
The key to successful gardening is choosing plants that are suitable for your zone and location. A plant that prefers shade, like an azalea, may develop poorly and be more susceptible to pests and disease if it is placed in full sun. Once, I planted a crape myrtle with some of its leaves in the shade. Only this area of the plant was affected by powdery mildew.
Similar to a person’s immune system, plants have defenses that kick in when they are being attacked by an insect or illness. When plants are stressed, they are less able to respond to diseases or recover from them. Therefore, stressed plants are more likely to succumb to these diseases.
Water properly
It’s a good idea to water your garden, but since many diseases require water just as much as plants do, how you go about it matters a lot. Water is necessary for many pathogens in the soil and air to travel, grow, and replicate. Select watering techniques that minimize moisture on a plant’s leaf to prevent providing these diseases with a habitat they adore. This is achieved using soaker hoses and drip irrigation. Hold the leaves out of the way when you water the roots if you are watering by hand.
The least ideal alternative is overhead sprinkling because the most frequent leaf issues are made worse by wet leaves. However, if you go with this approach, water when the leaves are about to dry out quickly but the roots still have time to absorb the water before it evaporates.
Additionally, keep in mind that while giving your plants water, more isn’t always better. Some root-rotting fungus are encouraged by wet soil or containers, and these conditions can also suffocate roots, making them easy prey for the fungi.
Don’t crowd plants
Carefully consider the distance between transplanting, and monitor the spread of existing plants. Because crowded plants produce their own humidity, diseases including downy mildew, rust, and powdery mildew can flourish. This high relative humidity can be decreased by increasing airflow around your plants, which also speeds up the drying of the leaf.
Plants put too close to one another compete with one another for light, water, and nutrients, which results in poor growth. These vulnerable plants are more easily attacked. When plants are close to one another, it is more probable that an infected leaf may come into contact with a healthy one, which is another way that diseases might spread.
On plants like Phlox paniculata that are prone to powdery mildew, remove crowded, damaged, or old stalks to reduce the risk of illness. When your plants require it, dividing or rearranging them will also be beneficial.
Why are the leaves on my plant bright green?
Lack of sunlight is the most frequent cause of paleened leaves. You probably already know that chlorophyll, a molecule that enables plants to convert light into energy through photosynthesis, is abundant in leaves.
Chlorophyll turns a brilliant green color when your plant is happily converting light into food.
Chlorophyll and the leaves remain pale when your plant doesn’t receive enough light to produce energy. Note that even if your plant doesn’t have green leaves, its leaves still contain chlorophyll.
Simply relocate your plant closer to a window or somewhere else that is a little brighter.
Why aren’t my houseplants green?
Although popular and affordable, plants do need some upkeep and care to look good in any living space.
Quality soil is essential for giving plants the nutrients, air, and water they need. Most indoor plants need either potting compost or potting soil. In contrast to natural soil, potting compost has soil conditioners that are nutrient-rich, have the right amount of aeration, and have good drainage. Usually, peat, perlite, and vermiculite are combined in the mixtures.
Normally, natural soils don’t drain well. Therefore, refrain from going outside and picking up a pile of dirt from the backyard to place in the pot with your plant.
The survival of your plants depends on how well you water them. So, how should a plant be watered properly?
Fill the entire soil column with water. Many individuals believe that watering their plant just a little bit every day or two is the proper method. It’s incorrect! You are denying your plant food. The earth is absorbing that tiny amount of water, which never gets to the roots of the plant. You should actually give it a decent supply of water every time you feed it because plants can only take water that is loosely held.
Another typical error is to pour water that has accumulated in saucers back into the plant. You could just poison your plants instead! This water had already been through the soil once, where it picked up some dangerous elements, mainly salt, before entering the saucer. Salt is the enemy of plants, and inadequately cared-for plants frequently get salt burn.
In fact, the plant’s water content may be reduced by this moisture near the base. Because the water is actually being sucked out, sometimes you’ll notice the tips of the leaves turning brown. So use a turkey baster to suck the water out rather than letting it sit in a saucer. This will lessen the harm that this salty, stagnant water can do.
The growth of your house plant depends greatly on the size of the pot you choose. Your pot shouldn’t be either too big or too little. A plant’s ability to grow will be constrained by a pot that is too small, while an excessively large pot may result in root disease on your plant due to the excess moisture in the soil.
The drainage system in pots and containers is possibly the most crucial component. You can use the same pots for other plants, but make sure to properly wash them first to get rid of any bacteria or disease that could have been left over from earlier plants.
Additionally, when using large containers, cover the top of the floor plant’s dirt with saturated sphagnum moss (available in dry form). This will improve the indoor presentation of your plant.
Does Epsom salt help plants grow more greenery?
Yes, it appears that there are valid, pertinent justifications for utilizing Epsom salts with plants. Epsom salt increases a plant’s green hue and helps flowers bloom more effectively. It may even encourage bushier plant growth. Epsom salt is composed of hydrated magnesium sulfate, which is essential for wholesome plant growth.
Why is Epsom salt beneficial to plants?
Some of the greatest gardeners in the nation advise utilizing Epsom salt as a cheap way to start or improve your garden as spring approaches.
Magnesium sulfate, often known as epsom salt, promotes seed germination, bushier plant growth, more flowers, increased chlorophyll production, and insect deterrence such as slugs and voles. Additionally, it offers essential nutrients as a complement to your usual fertilizer.
According to Neil Mattson, an assistant professor at Cornell University, plants will display visual indications if they are lacking in a specific nutrient. A plant may require extra sulfate if all of its leaves start to turn yellow at once. Lower leaves may require extra magnesium if the veins remain green but turn yellow in the middle. Growers should speak with their county extension agents before planting to test a soil sample or, if they discover a problem, they can bring in a plant for diagnosis because certain nutritional problems can look alike.
According to Mattson, plants require these building blocks.
Sulfur and magnesium are vital nutrients.
Despite the fact that magnesium and sulfur are found in soil naturally, they can be depleted under a variety of circumstances, including intensive agricultural use. But Epsom Salt is not persistent, so you cannot use too much of it, in contrast to the majority of commercial fertilizers, which accumulate in the soil over time.
Gardeners can either proactively mix Epsom salt with fertilizer and add it to their soil on a monthly basis, as Mattson does, or they can mix one tablespoon with a gallon of water and directly spray leaves every two weeks. Mattson adds Epsom salt to his fertilizer for plants like roses, pansies, petunias, and impatiens.
Master Gardeners advise using Epsom Salt, and professional growers all over the world frequently do. According to National Gardening Association tests, Epsom salt fertilization causes pepper plants to grow larger than those that are only given commercial fertilizer. It also causes roses to grow bushier and produce more flowers.
