#10. About to repot your plant? Did you know that unnecessary repotting is the single most common cause of plant failure? Before you repot you better read Indoor Plant Bulletin #18.

Week of 6/29/08 Newly purchased plants require more water in the first few weeks following purchase. After that, their water use tends to decline gradually before stabilizing at a reduced rate. This is because the growth rate (metabolism) of new plants is determined by the ideal conditions of the greenhouse. This rate slows in the less than ideal conditions of the home environment. To learn more about how plants acclimate to the home, subscribe to Indoor Plant Bulletins.
Week of 6/22/08 Potted plants do best when 80% of the soil ball is filled with roots. Premature transplanting can cause root rot and prevent flowering plants from blooming. Subscribe to the Indoor Plant Bulletins to learn how to avoid the hazards of repotting.
Week of 6/15/08 Observe your plants, especially the new growth. If the new growth is healthy, then your plant is also. Stunted or discolored new growth is a sign of a root problem or possibly plant pests. If the new leaves are much smaller than the older leaves, then you may not be providing enough light.
Week of 6/8/08 Soil replacement and root washing are very common plant care mistakes with terrible consequences. Such treatment often damages the tiny root hairs that do most of the work and it takes the plant many months to recover. If you are thinking of doing this to eradicate soil pests or to dry out the soil – don’t. There are other solutions for these problems.
Week of 6/1/08 Recommended rates on fertilizer labels are based on plants living in optimal conditions. If you have less than ideal light for your plant, then reduce the recommended rate accordingly. In general, that means using fertilizer at half the recommended rate. For everything you need to know about fertilizers and plant foods, subscribe to the Indoor Plant Bulletins.
Week of 5/25/08 Commercial pesticides are usually no more effective than safer alternatives and they are potentially more hazardous. Subscribe to the Indoor Plant Bulletins to learn all about common indoor plant pests and how to treat them safely and effectively.
Week of 5/18/08 Garden soil, topsoil, and compost are poor choices for potting indoor plants. They are a source of plant pests, fungi, and odors that you do not want in your home. Sterilized peat-based soilless potting mixes are best for indoor plants. To find out why, subscribe to the Indoor Plant Bulletins and learn all about the importance of using proper potting mixes for your plants.
Week of 5/11/08 Spring is a good time to consider serious pruning. Many houseplants are overgrown, leggy, and sparse in their center areas after a long winter indoors in reduced light with shorter days. Most plants benefit from regular pruning because it keeps them compact. Spring is a good time to prune because the longer days signal renewed growth for the coming months. The new growth will soon replace the leggy stems that you have removed. HAPPY MOTHERS’ DAY!
Week of 5/4/08 You can’t tell if a plant needs a larger pot based on how it looks. Repot a plant only when it needs water again within a few days after a thorough watering. Subscribe to the Indoor Plant Bulletins to find out more about proper repotting techniques.
Week of 4/27/08 Hard water contains high levels of minerals that are not healthy for potted plants. If your local tap water is hard, use filtered or distilled water instead. Rainwater is another alternative. Chemical water softeners also contain toxic salts so softened water is not a good substitute for your plants. Subscribe to the Indoor Plant Bulletins to learn more about the toxic effects of mineral salts on plants and how to avoid this problem.
Week of 4/20/08 Here are some things that don’t matter much to the health of your indoor plants:
Subscribe to my Indoor Plant Bulletins and learn the surprising reasons why these don’t really matter and may actually cause some damage to your plants.
Week of 4/13/08 Properly potted plants should dry out within 7 to 14 days at the most. If it takes longer for your plants to dry out, then the pot is too big or the soil is too dense. Root rot will soon follow. Subscribe to the Indoor Plant Bulletins to find out more about proper potting techniques.
Week of 4/6/08 Can indoor plants get too much light? Most definitely. Many common houseplants must be protected from direct sunrays coming in through the window. These plants grow naturally in the deep shade of the tropical forest. We usually refer to these plants as “low light” plants. In addition, plants that have been inside during the colder months must be protected from the direct sunlight when they are moved outside during the warmer months.
Week of 3/30/08 As spring approaches, are you thinking about moving your houseplants outside for the warmer months? Here are some things to consider BEFORE you move your plants outside.
For more information about moving plants outside, send an email to wcreed@HorticulturalHelp.com and ask for Indoor Plant Bulletin #10.
Week of 3/23/08 The key to eliminating indoor plant pests is not what you use, but how you apply it. There are many safe remedies for plant pests that are effective, but only if they are applied to all leaf and stem surfaces of the infested plant. To learn how to identify and treat plant pests safely and effectively, subscribe to the Indoor Plant Bulletins.
Week of 3/16/08 Yellow leaves have many causes: under or over watering; too little or too much light; temperatures too high or too low; adjustment to a new environment; natural aging; and insect pests. Whenever something is wrong in a plant’s environment, the plant will respond with yellow leaves. Find out how to figure out why your particular plant is getting yellow leaves, subscribe to the Indoor Plant Bulletins.
Week of 3/9/08 Most of the common indoor plants do not require increased humidity to do well. Plants that do require constantly moist air are not generally available as houseplants. To raise humidity around your plants, use pebble trays or room humidifiers. Misting does not raise humidity effectively, although it does help keep plants clean and deters spider mites. Subscribe to the Indoor Plant Bulletins to learn more about humidity and plant pest control.
Week of 3/2/ 08 Transplanting into too large a pot is the single most common cause of plant problems. If you think your plant needs to be in a larger pot, it probably does not. Plants that look too big for their pots or that have roots coming out of the bottom often do not need a larger pot. There is a simple way to determine when a plant needs a bigger pot. Subscribe to the Indoor Plant Bulletins to find out how and to learn how to avoid the hazards of repotting.
