Pruning a Ficus Benjamina
Posted On 2010-03-17 , 3:01 AM
We will need to prune our Ficus Benjamina periodically to keep it healthy, full and attractive.
We may need to prune to...
1.-remove dead branches. Dead branches are not only unsightly, but will interfere with new growth.
2.-reduce the size of the houseplant. The ficus benjamina or weeping fig, can grow rather large in both height and spread. If left unchecked it can demand more and more space until it needs more space than we are willing to give it.
3.-get rid of weaker growth to produce a stronger plant. The weeping fig produces many thin branches that bend under the weight of the leaves. This is an attractive feature of the houseplant. Pruning will be needed however to encourage stonger growth to produce a shaplier plant as it matures.
4.- create a bushier, more shapely plant. Pruning will encourage the branches to divide producing a thicker, fuller houseplant.
5.- make room for new growth.
We should remove dead growth any time it appears. Cut away all of the dead material.
Pruning for other reasons should be carried out in the spring when the new growth begins to appear.
We should always use sharp tools to make the cuts as the will cause less damage to the branches. The cuts will heal faster and allow less time for disease to attack the open wound.
Cuts should be made just above a node on a branch, as that is where the new growth will begin.
Ficus benjamina can withstand removing up to 1/3 of the plant if needed. This is referred to as a hard pruning.
The new growth will fill in the areas where branches have been cut away making a fuller bush.
The ficus benjamina shown in the images had not been pruned in 2 or 3 years. It was pruned to remove some dead branches and weaker growth and to reduce its spread. It was claiming more of my living room than I was prepared to give it.
Regular pruning of your ficus benjamina will control its size and shape and improve its appearance.

Getting Rid of Mold on Houseplant Soil
Posted On 2010-03-05 , 1:20 AM
If you notice a white or yellow substance on the top of your houseplant soil, it may be that one of the many varieties of mold or fungus has found a home in your houseplants.
Mold and fungii are spread by spores. By the time you see the mold or fungus on the surface of the soil, milions of spores have already been produced.
When a houseplant has fungus growing on the soil, it should be separated from the other houseplants. The spores are very tiny. It only takes a small disturbance to send the spores airborne where they will move to the other houseplants nearby.
While many molds and fungii are actually beneficial to plants, they may be toxic to people. Great care should be taken with mold. They may also cause reactions in people with allergies or sensitivities to molds. It is suggested that you should use latex gloves and a mask when dealing with mold and fungii.
Several things can be done to reduce or get rid of an infestation. These methods will need to be used if changing the plant's growing environment do not control the fungus outbreak. Fungus likes darkness, heat, high humidity and stagnant air. Fungus may disappear if we move the houseplant to a brighter location, a cooler location, a drier location or a location where there is more air movement.
1. You can carefully remove the top 2 inches of soil where most of the spores would be located. You should move the plant outdoors, if possible, to do this. Remember, disturbing the soil will send the spores airborne and they will spread around the room. Then replace the soil with sterilized potting soil.
2. If the fungus returns or the infestation is extensive, you can repot the houseplant. This should be done outside, if possible, so that the spores will not be spread around the room.
Take the plant out of the pot and remove all of the soil from around the roots. The soil may be washed from around the roots taking care not to damage the roots. Before replanting, the pot should be washed with hot water and bleach to get rid of the mold and spores. Then replant in the pot with new sterilized potting soil.
3. Another method that works is to use a weak vinegar solution. The mold or fungus does not grow well in acidic soil, but be careful as your houseplant may not either.
Mix 1 part vinegar with 10 parts water and spray the affected area. Spray enough that the affected area is totally damp but not so much as to moisten the soil down more than an inch.
Spray once between waterings and don't water for a day or two after watering to allow the vinegar to kill the fungus. This will need to be repeated as additional spores already in the soil start to grow.

White Mold or Fungus on Houseplant Soil
Posted On 2010-03-03 , 5:09 PM
Mold and mildew are types of fungus. They grow from tiny spores that will float in the air from one place to another. They produce millions of spores. Once you have a mold or fungus infestation, it is very difficult to get rid of but can be controlled.
Fungus likes higher temperatures ( 75 to 90oF), high humidity, stagnant air, and darkness. If we control these factors, we will have some success in controlling the fungus.
1. Keep the temperature in the lower range (60 to 70oF). The mold will not grow as well at those temperatures.
2. Usually it is not difficult to keep the humidity at an acceptable level. Too high a humidity is often caused by overwatering or using plant pots without drainage holes in the bottom.
Always make sure that the plant has dried sufficiently between waterings. Test the soil with your finger down at least 1 inch (2 inches in pots 10 inches in diameter or greater) If the soil is not dry that far down, the houseplant does not need to be watered yet.
If the pot has no bottom drainage, the soil will remain much moister lower down in the pot. The water has no where to go but up and will raise the humidity near the surface of the soil.
3. While it is best to keep most house plants out of drafts, some air movement is needed. This circulation will disperse the oxygen and humidity given off by the plant throughout your room and replace the air around the plant with new room air. This will benefit you and your houseplant. It will also help dry out the surface of the soil where the fungus will start to grow.
4. Mold and fungii grow best in darker conditions. If you place your houseplant in a brighter location, the mold will not grow as well.
These are just some of the methods we can use to discourage the growth of mold and fungus on the soil around our houseplants.
