Q: Some manufacturers recommend that you do not submerge their products.  Submerging an air mattress puts it into contact with a lot of water. Fabric may become saturated. Once an air mattress is saturated with water, seams may begin to deteriorate. Protective coating on synthetic fabrics may also begin to separate from the fabric. If it is not at least partially inflated, you you not be able to see air escaping under water. Fully inflating the mattress may make it very difficult to submerge in a pool or bathtub. Apply pressure around the valve stem.    See if you can force any air out of the valve. Escaping air will cause a stream of bubbles to form around the leak. Look for these around the valve as you apply pressure. Submerge parts of the fabric under the water. Look for bubbles, indicating escaping air from a leak.  Do this in sections. Looking at a smaller area is easier than trying to find leaks in the whole mattress at one time. Pay close attention to the areas around the seams. Seams are a common area for holes and tears to occur. Mark the leak with a permanent marker once you find the source. Permanent marker is less likely to bleed on a wet surface.   You can partially dry the area around the leak with a towel to aid in marking the leak. Once the mattress is dry you can make your mark more clear by placing duct tape or a larger mark near the leak. The seams will take the longest to dry.  If you don't dry a mattress before storing it, mold or mildew can form. It is important to make sure it is 100% dry before you put it away. Before you can use any kind of adhesive patch to repair your mattress, it must be 100% dry.
A: Check the label of your air mattress. Partially inflate the mattress with air. Submerge the valve stem in a pool or bathtub filled with water with the valve closed. Dry the mattress in direct sunlight or in the wind for an hour or two.

Q: When you want to clean non-porous surfaces such as toilets and showers, sinks, and vinyl or tile floors, use a bleach to water ratio of 1:32. Add a half cup (118.3 ml) of bleach to a gallon (3.8 L) of water. Mix this in a sturdy plastic bucket. Using a mop for floors or a clean rag for other surfaces, carefully dip into the solution and wring the mop or rag out. Wipe the surface in sweeping motions. Go in a back and forth pattern to make sure you cover the whole area. Make sure not to clean with bleach on surfaces like wood, leather, canvas, or carpet. Bleach will stain and fade this type of porous surface. If you let the bleach solution dry on the surface, it can leave residue. Always use a bucket of clean water, and a clean mop or rag if possible, to completely rinse the surface. A bleach odor may remain in the air after you rinse the surface, which is okay.
A: Mix bleach and water in a ratio of 1:32. Apply the solution to the surface you want to disinfect. Rinse the surface with clean, cold water.

Q: Use a garden hose to water the soil around the tree once a week, applying just enough water to create visible moisture on the surface of the soil.  During rainy seasons, additional waterings may not be needed. On the other hand, during abnormal droughts, you may need to increase your watering schedule from once to twice a week. Regardless of how the weather is, the idea is simply to keep the soil regularly moist. Consistent sources of water are especially important while mahogany trees are young and have not yet established themselves. Fully mature trees can tolerate some drought without dying, but dry spells may cause the tree to drop its leaves early for the season. Feed the tree with a dose of fertilizer in the spring, summer, and fall. Use a balanced granular fertilizer for best results.  The same type of fertilizer used at the time of planting can be used for yearly maintenance. The fertilizer should contain equal parts nitrogen, phosphorus, and potassium. Follow the dosage instructions provided on the label of the fertilizer used. For best results, mix the fertilizer into the soil around the tree instead of spreading it over the surface of the soil. During the first two to eight years of the tree's life, yearly pruning can help control the height and spread of the tree.  Check the arrangement and space between limbs. The healthiest mahogany trees will have several evenly spaced major limbs that spread out along one central trunk or central leader. As the tree grows, these limbs will be at least 2 feet (61 cm) apart from one another, if not further. Prune away any upright leaders aside from the central trunk. These upward growing branches can make it more difficult for the tree to tolerate strong winds and storms, thereby weakening it. Cut away any branches that grow larger than two-thirds of the diameter of the central trunk. Such limbs can put stress on the tree and shorten its lifespan. There are a few common pests that may present a problem to the health and longevity of your tree. When you spot such pests, apply an appropriate pesticide to the area.  Some of the biggest problems come from shoot borers, longhorn beetles, powder post beetles, tent caterpillars, tip moths, scale, leaf notchers, leaf miners, Cuban leaf beetles, mahogany webworms, and Sri Lanka weevils. Among these insect pests, borers present the greatest threat to the health and longevity of the tree. When borers are present, pesticides should be applied. The other pests mostly cause aesthetic damage to the tree and don't often cause structural damage. As a result, pesticide application is not as crucial when these pests are spotted. You can treat the tree or choose not to do so. When selecting a pesticide, look for one specifically labeled to work against the type of pest you are trying to kill. Do not assume that all pesticides will work on all pests. While diseases rarely strike mahogany trees, nectria infection can develop when the tree becomes stressed or injured.  Look for discolored bark along the branches of the tree, particularly where the branch meets the trunk. As the fungal disease progresses, the discoloration can turn into small cream-colored to reddish cankers that develop on the surface of the bark. These bumps will continue to grow and can eventually kill entire branches or trees. The best way to save a mahogany tree facing nectria infection is to remove the infected wood. You may also apply a fungicide to the tree, but fungicides do not always work on this particular type of infection.
A:
Water regularly. Fertilize three times each year. Prune young mahogany trees. Watch out for pests. Monitor the tree for signs of infection.
