1. What is the best way to prune your crepe myrtle?
Answer: B. Although many people do chop off the top of their crepe myrtles, Karen says that this can weaken the new growth and leave the tree susceptible to disease and insects. Cutting off the older branches would also cut new growth, where flowers form. And cutting off the branches that have flowers won’t hurt the tree, but it’s definitely not the BEST way to prune your crepe myrtle.

Plants from the other groups have a mixture of high and low drought-tolerant plants, which would mean that you would have to water more frequently to keep the low drought-tolerant plants healthy. To see a complete list of stress-tolerant plants and their tolerance ratings, see the Horticultural Information Leaflet on Stress-Tolerant Plants.
2. What is something needed by ALL fruit trees to prevent the spread of disease?

1. You are working in your garden, and you see a live snake. Assuming that you're not planning on picking up the snake, what is the BEST way to determine whether or not it is a poisonous snake without getting too close to it?
Answer: C. Unless it's a very large snake and you have very good vision, the best way to tell if a snake is poisonous is to look at the head. Poisonous snakes have a distinctly triangular head, while non-poisonous snakes have more oval heads (they can be somewhat triangular, but they are not as distinct as they are with a poisonous snake). Often you can tell poisonous snakes by their markings, but if you're not familiar with them, they won't help. The best thing to do if you're not sure whether a snake is poisonous or not is to stay away from it!
2. How far up the tree do you want to prune before you have branches?
Answer: D. Bill Lord recommends pruning between 18-20 inches up the tree before the first whorl of branches.

The pavement, which consists of 4-inch concrete blocks separated by drainage holes, actually purifies stormwater runoff to make the resulting groundwater safe for drinking.

Answer: A. Apple trees need lots of light and air. They do need to be fertilized and watered, but fertilizing once a year is enough (in late winter or early spring), and they do NOT like to have wet feet, so planting in a moist site will kill the tree. Soil needs to be well-drained with plenty of organic matter. See the Fact Sheet for Apples at the Consumer Horticulture site for more information about growing apples.
