Q: Dahlias thrive in full sun, and should be planted in a location where they will be in direct sunlight for at least 6 to 8 hours a day. Dahlias also need to be protected from the wind, so plant them in a protected area. Their large flowers can become heavy when mature, and can snap off in a stiff breeze. Soil that drains well will not form puddles, and will allow the tubers to absorb what liquid they need without drowning. If you already have a garden or a section of your yard with well-drained soil, plant your dahlias there. If you're concerned that the soil may not drain well, add sand to your soil to improve your garden's drainage. Do this at the same time that you're adding the compost or manure. If your soil is clay heavy, work peat moss or compost into the soil to loosen it. This can make it easier to plant dahlias. Use a spade to work manure or another fertilizer into your garden a couple of weeks prior to growing dahlias. It's necessary to prepare your soil to grow dahlias before planting the tubers. Adding fully rotted compost or another fertilizer type to the soil will encourage the plants to grow well and bloom quickly. Each hole should be about 4 inches (10.16 cm) deep. When digging the holes, leave enough space between the plants that growing dahlias will not choke one another or steal nutrients from one another. For smaller varieties, leave 2 feet (0.61 m) between holes. For medium or giant dahlias, leave 2 to 3 feet (0.61 to 0.91 m) between holes. Dahlias need plenty of fertilizer to grow successfully, and adding organic material to the soil ahead of time will help ensure that the plants grow well. Scoop a small handful of compost and bone meal into each of the holes, and add a small scoop of dry fertilizer. You can purchase ground bone meal at a local plant nursery or gardening center. If you do not already own compost and fertilizer, you can purchase them from a large gardening center or from a landscaping outlet. Drop a single tuber in each hole, and then fill with soil. You can expect to see the tubers growing in 2 or 3 weeks. Be sure the growing point of the tuber faces upward before you cover it with soil. Wait until you see new growth above the soil before you water the dahlias. It can take anywhere from several days to a couple of weeks for new growth to appear.
A: Select a location with full sun and low wind. Plant your dahlias in well-drained, fertile soil. Add compost or manure to your soil. Dig holes for the dahlias tubers. Fertilize the holes before planting the dahlias. Plant dahlias in the prepared holes.

Q: Pluck stray insects from the leaves of affected plants and crush them between your fingers. Aphids have soft bodies, which make them easy to dispatch with a single squeeze. If you're dealing with more than about half a dozen, it may be easier to use a damp paper towel to wipe them away. Always wear gloves when removing aphids by hand to protect your skin from potential irritants. While aphids usually migrate and feed in colonies, they can also appear 1 or 2 at a time. A forceful stream of water should be enough to dislodge stubborn pests. Direct the stream toward the underside of the leaves, where aphids tend to congregate. Hose down your plants 1-2 times a day until the infestation starts to thin out. Avoid using a pressure setting high enough to damage the plant itself and refrain from overwatering. Regular spraying is most effective for combating small-moderate infestations on hearty, established plants. Allow the leaves to dry completely between waterings. Wet foliage increases the risk of diseases like blight and rust in plants that are sensitive to moisture. Trim heavily-infested sections where the greatest number of aphids are concentrated. This may involve plucking leaves or fruits, clipping stems, or even removing whole branches. Check to make sure you haven't overlooked any insects on other parts of the plant. After cutting back the affected plant, douse it thoroughly with water or a homemade aphid repellent solution, such as those enumerated here. Selective pruning works best when aphids are confined to one specific section of the plant.
A: Pick off small numbers of aphids by hand. Spray the leaves of infested plants with a garden hose. Cut back the plant to eliminate large colonies.

Q: Before you start cleaning, you'll want to make sure that there's no power going to the razor. Slide or press the power button to the "off" position and look for the power indicator display to go dark. It may be a good idea to unplug the razor entirely. You don't want to accidentally switch it on while you're trying to clean it!
A:
Make sure the razor is turned off.
