Houseplant Problems

Proper care can extend the lives of houseplants. This NebGuide offers hints on caring for houseplants, including conditioning, light, and fertilizing. Frederick P. Baxendale, Extension Entomologist Stephen N. Lott, Extension Educator Dale T. Lindgren, Professor Emeritus. Today, houseplants are an integral part of indoor decor throughout the year.

An artificial indoor environment often hinders plant development. High temperatures, low humidity, lack of sunlight, poor soil conditions, and improper watering often contribute to most houseplant problems.

Occasionally, insects or plant diseases damage houseplants. Many houseplants may eventually become unattractive or too large for the home. Before discarding these plants, use them for cuttings or divisions for new plants.

However, proper care can extend their lives. Conditioning Your home usually has a lower light intensity and lower humidity than the plant experienced before purchase.

As a result, houseplants may lose some of their foliage within a week or two of purchase. Conditioning plants to the home environment extends their useful life, so purchase preconditioned plants whenever possible. These plants are found at retail centers, growing in lower light and humidity levels typical to home growing conditions. Condition Newly Obtained Plants First, expose your plants to the maximum amount of available indoor light.

This is usually a site close to a south window. Second, over a period of four weeks, reduce the available light to the intensity of the location selected for the plant. Third, leach the growing media by allowing water to filter down through the soil and escape through the drainage hole. Allow the growing media to dry before leaching again. Repeat this leaching process four or five times.

This removes excess fertilizer or salts that can cause leaf drop when light intensities are low. Greenhouses are more humid than most living areas. While you cannot duplicate that environment in your home, using a humidifier benefits both you and your plants.

Light Homes vary in the amount of light available for plant growth. Generally, the brightest location in any home is near a south window, while the darkest is across the room at a north wall.

About the same amount of light is received by a houseplant located by an east or west window. However, plants with a western exposure are exposed to a much higher temperature. Seasonal variations in light intensity occur within a home. Plants located in an east window during the summer may require a south exposure in winter. Since most homes provide less than adequate light for many plants, consider selecting plants requiring medium to low light unless supplementary light can be provided Tables I-III.

Plants such as Chinese evergreen, cast iron plant, philodendrons, Boston fern, and Sansevieria tolerate very low light intensities. When plants are located in low-light areas less than the foot candles that are necessary for reading , use the minimum recommended day-night temperature found on the information tag on each houseplant. Light usually strikes the plant from only one side. Rotate the plant to maintain an upright growth habit. Symptoms of insufficient light include small leaves; long, thin stems; and a lighter than normal color.

Where light is limited for plant growth or desired quality, supplement the natural light with fluorescent lamps. Plants that struggle to exist indoors will thrive with 12 to 16 hours of supplemental light daily.

Some houseplants can be placed outside in summer. Plants often are revitalized by this treatment. However, to avoid sun scorch, condition your plants to the higher outdoor light intensities.

Do this by initially placing the plant in the shade and then, over a four or five week period, gradually expose the plant to increased light intensity. Temperature Plants vary in their temperature requirements. Generally, as temperature increases, the requirement for light increases.

In most homes, plants will be healthier if day temperatures are in the low 70s rather than the 80s. Reduce temperature swings inside the home. During the winter, remove plants from window ledges to reduce exposure to freezing temperatures.

Be very careful with foliage plants such as African violet, croton, and prayer plants, which prefer warm night temperatures. Plants grown at warmer temperatures than recommended often are weak and have spindly growth.

Plants grown at temperatures too low for growth and development have translucent leaves that yellow and fall off suddenly. Humidity Most houseplants are injured when humidity is under 20 percent, with the exception of succulents. Humidity levels between 40 and 60 percent are preferred. Symptoms of low humidity are leaf drying and curling. During winter, humidity may reach very low levels, under 20 percent, in the home. The best way to increase humidity is to use a room humidifier or a whole-house humidifier which is attached to the furnace.

Use a portable humidity monitor to determine the humidity level and monitor fluctuations over time. Syringing spraying plants with clean water removes dirt from the leaves and increases humidity to a degree. Be sure to syringe plants early in the day to allow the leaf surface to dry. High humidity areas such as bathrooms and kitchens often are ideal for plants. Consider growing plants that require very high humidity levels greater than 50 percent in terrariums or greenhouses.

Houseplants should be grown in containers with drainage holes. Drainage holes can be covered with a coarse piece of window screen or similar product to prevent growing media from leaching out. Both plastic or clay pots are available.

Media in clay pots dry out faster than in plastic pots, so people who tend to overwater should use clay pots, although that is not a cure-all for incorrect watering.

Clay pots are more difficult to clean than plastic pots because clay absorbs chemicals and salts. To clean pots, soak them in very hot water for 24 hours.

Use a stiff brush to remove soil. To sterilize pots, soak them in a solution of one part chlorine bleach to nine parts water and then rinse thoroughly. Plants obtain water, oxygen, and nutrients from the rooting media in which they are growing. With few exceptions, a well-drained growing media is important to obtain optimum houseplant performance.

Most foliage plants thrive in a mix of one part sandy loam soil, three parts organic matter and one part perlite. Mixtures for succulents and cacti require additional coarse-textured material, such as sharp sand. Various growing mixes are available for purchase to meet the growing needs of houseplants. The amount and frequency of fertilizing depends on the type of plant, desired growth rate, available sunlight, media mix, frequency of watering, and type of fertilizer.

For actively growing plants, fertilize every two months between March and September. Do not fertilize dormant plants. A number of fertilizer formulations are available for houseplants. Specific formula recommendations will vary with the type of the houseplant. A general formulation contains equal amounts of nitrogen and potassium and twice as much phosphorus, such as orA balanced ration fertilizer with equal parts of nitrogen, phosphorus, and potassium, such as , also can be used.

Follow all label instructions when mixing and applying fertilizer to houseplants. Avoid over-fertilizing houseplants, especially for plants growing under low-light intensity. Burned or dried leaf margins and wilted plants often are a sign of excess fertilizer application.

Leaching the potting media in the container with water to help remove excess salt and fertilizer is beneficial. Although no exact recommendations can be given for watering plants, there are general guidelines.

If the growing media is excessively dry or the plant is root-bound in the container, water the plant from the bottom of the container by placing the container in a larger pan of tepid water to hydrate the growing media until the top of the media in the container is moist to the touch. Thoroughly wet the growing media in the container at each watering.

Water should drain out the bottom of the pot after watering. Frequency of watering depends on many factors, including moisture needs, humidity levels, plant types or species, and containers. To determine if the media is at the correct moisture level for the needs of a specific houseplant species, test it by placing a finger 1 to 2 inches into the media. Larger plants need more water compared to smaller plants. If the container is too small for the plant and the amount of growing media has decreased over time, watering frequency will increase.

Wet soils can lead to root rot. Excessively wet soils lack the oxygen required for root growth. Yellowing foliage results from poor soil aeration. Excessive fluoride levels in the water can cause tip and leaf scorching. Plants like Dracena, Cordyline , and Chlorophytum should be watered with rain water if possible.

Why is my indoor plant unhappy?

Indoor plant pests and diseases can strike at any time, replacing the glory of new unfurling leaves with yellowing ones. While a plague of pests and fungus can make short work of your indoor plant collection, there's no need to panic. Not sure what you're looking for or what to do next? Read on for Craig's tips for treating common pests and fungus.

Is your plant looking a little yellow, brown or wilted? It could be a sign of plant disease. Use this guide to identify & treat common plant.

Indoor Plant Diseases

Protect your plants from debilitating diseases by learning to recognize the symptoms and practice prevention. A wholistic approach includes first identifying the pathogen. Then decide on a treatment method that is safe, effective and responsible. Read on and bookmark this page for plant disease identification. Black spot is one of the most common diseases found on roses, but it can also occur on other ornamental and garden plants. This fungal disease causes black, round spots that form on the upper sides of leaves. Lower leaves are usually infected first.

Caring for Indoor Plants- Diseases & Treatment

Make a donation. Older leaves on healthy houseplants will naturally turn brown and die back over time as the plant matures, which is no cause for concern. But if most of the foliage on the houseplant changes colour in part or whole there may be a cultural problem, often rectified by paying more attention to watering, feeding or moving the plant to a more suitable position indoors. Plants that are unsuited to the conditions are unlikely to survive let alone thrive in the long term.

Consider the growth conditions of your indoor plants when investigating plant problems. Indoor plants make great roommates.

How to Manage Pests

More Information ». Houseplants can develop many problems, but most have environmental or cultural causes. Diseases are not common on most houseplants grown indoors because environmental conditions are not favorable for plant pathogens to grow and infect the plants. Control of diseases begins with prevention. Always buy disease-free plants. Use pasteurized soil when repotting.
