Q:What’s the difference between Potting Soil and Topsoil at the garden center?
A:Potting soil primarily consists of perlite, aged compost, peat and vermiculite, and might not actually con- tain any real soil. It’s typically used for gardening in pots or containers to help plants retain nutrients. Potting soil also helps reduce compaction, which can prevent plants from filtering out carbon dioxide and other toxic gasses that can kill the roots. It’s best used in containers because when combined with an outdoor gar- den, it can cause the garden soil dry out because it can drain too well. Topsoil is taken from the top of a field, so it has a wider range of materials and is best com- bined with existing garden soil. Avoid using topsoil for containers because it can sometimes be too moist for containers and cause root rot.
Q:My neighbor says I need kickout flashing on my roof. What would this accomplish?
A:A great volume of water can pour down a sloped roof, and one of the most critical flashing details occurs where a roof intersects a sidewall. The roof must be flashed with step flashing. Where the roof terminates, an angled piece of kickout flashing is used to deflect water and prevent it from dumping behind the siding at the end of the roof intersection. The flashing should be a min. of 4 in. high and 4 in. wide with an angle between 100° and 110° to maximize water deflection.
