Even though a cooler is meant to keep everything cold, you can also use it to keep hot foods hot. Double-layer aluminum foil around the interior of the cooler. The aluminum will hold the heat inside your cooler. Lay out a large piece of aluminum foil on your counter and set your hot container onto it. Make sure your food is piping hot as you wrap the foil around it. Use a few pieces of foil to cover the container completely. Use an oven mitt as you wrap the foil so you don't burn yourself. Set the container in the middle of the cooler. The heat from the container will transfer through the aluminum foil and keep the entire cooler warm. Fill new cotton socks halfway with uncooked rice. Once you have the rice inside the sock, tie a simple knot on top so none of it spills out. Use a string to tie the socks for added security. Dried beans will also work similarly. Use the regular settings on your microwave. Once they are finished, they will be nice and warm and they will hold heat for a while. Fill in the large spaces on each side of your food container. This will add more heat to the cooler and help your food stay at a reasonable temperature. Use clean towels so your food doesn't move around while you transport it. Make sure the towels are tight against your food so they insulate the heat inside. Fill a rubber hot water bottle with boiling water. It's easiest to pour the water into the bottle from a kettle or a pot with a spout. Place the hot water bottle on top of the cooler for one final heating element to keep your food warm. Seal the lid of the cooler tight after you add the water bottle so no heat can escape. The temperature of the cooler will start to drop over time. Carry a food thermometer with you to check on the temperature of your food to make sure it is above 140F (60C).

Strong, healthy plants will be more resistant to diseases of all kinds, so the fight against rose disease starts at planting time. Select healthy rose plants that have sturdy-looking leaves and stems and don't show any signs of disease or pests. Look to see if any of the leaves have black spots, red leaves, or chew marks. These are all signs of disease or infestation. Despite their name, Midnight Blue roses actually prefer sun to shade. They need about 6 hours of direct sunlight a day to be at their best, though they will still survive in very bright shade. Container rose bushes should receive a minimum of 4 hours of direct sunlight a day. The hole needs to be wide enough and deep enough to hold the roots when they're all the way spread out. Aim for a size of about 2 feet (60 cm) wide and 2 feet (60 cm) deep. If you come across weeds or stones as you're digging, use a garden fork to turn the soil over and remove them. Pull up anything that won't allow the roses' roots to venture freely. If planting multiple shrubs, space them at least 2 to 3 feet (60 to 90 cm) apart to allow space for growth. Roses love soil that is enriched by manure, so incorporate some into the soil where you intend to plant your rose bush. You can purchase well-rotted manure at your local garden store. Be sure the manure is at least 3-4 years old, since new manure can burn the roots of roses. Try to incorporate roughly a bucket full of manure per square meter of soil. Alternatively, you can use decomposed compost instead of manure. Organic mulch should be spread over the dirt around a Midnight Blue rose bush to help retain moisture in the soil and keep weeds from growing. Apply a 2 to 3 inch (5 to 7 cm) layer, and maintain this level throughout the plant's life. Use shredded bark mulch that has been properly processed to remove insects and diseases. Pre-packaged mulch that is sold at garden centers is the safest bet. It should state right on the bag that it has been composted or sterilized.
