In one sentence, describe what the following article is about: Rhubarb is a cool-season plant that requires temperatures that drop below 40 °F (4 °C) in order to stimulate growth. The northern states in the US as well as Canada are good places to grow rhubarb. Check your growing zone to find out if you can grow rhubarb in the climate where you live.  Rhubarb grows best in USDA hardiness zones 3-8. This includes much of the northern parts of the Midwest as well as the northeastern regions of the US. Rhubarb wilts during the heat of hot southern summers. If you live in a southern region where it regularly goes above 75 °F (24 °C), it will probably be difficult to grow this plant. Rhubarb is best grown from roots (crowns), not seed, since the seeds take a long time to get established and there's no guarantee they'll ever germinate. Go to your local nursery and buy rhubarb roots or purchase some from an online source.  If you have a friend with a rhubarb plant, you may be able to dig up a crown from the side of their plant to get yours started. Rhubarb should be planted in an area in full sun. Look for a spot that drains well, since rhubarb won't do as well if water sits around its base. To determine whether soil drains well, dig a hole and fill it with water. If the water sits in the hole, the soil there doesn't drain well. If it immediately soaks into the ground, the soil is great for planting rhubarb. You may want to stick a ruler in the hole so that you can measure how quickly it drains. Ideally the water should drain out at a rate of 1-3 inches per hour. If it drains too fast, your plant will dry out; too slow and the roots may rot. Clear out weeds and other plants that may interfere with the rhubarb plants. Till your gardening bed to a depth of several feet and mix in plenty of compost, rotted manure or other organic matter to enrich the soil. This step is essential, since rhubarb needs plenty of nutrients to grow well.   You can also consider  building a raised bed to plant your rhubarb and other vegetables. This way you can control the soil drainage and weed population more easily. Don't treat the area with herbicides or pesticides; rhubarb should only be planted in clean soil.  Don't use chemical fertilizer to treat the soil during the first year of growth; only organic material should be used until the second or third year. Rhubarb plants can grow to become quite large, so it's important to give them plenty of space. Dig the holes in rows. Place the roots in the holes and gently fill them in with compost-rich soil. Water the roots after planting.
Summary: Determine whether you're in the right growing zone. Get rhubarb crowns to plant in the spring. Choose a planting site. Prepare the soil for planting. Dig 4–5 inch (10.2–12.7 cm) holes 3–4 feet (0.9–1.2 m) apart. Plant the roots 2 inches (5.1 cm) below the surface of the ground.

Many personal finance magazines and blogs on travel hacks have articles that compare the frequent flyer mile programs of the major airlines. You’ll want to look for which programs give you the most miles per dollar, which ones allow you to exchange points from other affinity programs for miles, and other terms of the programs. Some rewards programs offer higher points-for-miles exchange rates than others. Others offer better selections of vacation packages. But some cards only work with a limited number of airlines. Make sure that your choice of frequent flyer program is aligned with any rewards programs you are already enrolled in. Enrolling is usually as simple as going on the website of the airline carrier, creating a frequent flyer rewards account, and agreeing to abide by the terms and conditions of the frequent flyer miles program. Some companies have prohibitions against this, but many companies, especially smaller ones, do not. If you work for a company that lets you take advantage of those miles, ask the appropriate staff person to start booking your business flights on the airline where you have your frequent flyer miles program set up. Make sure to check with a tax professional to determine any tax-related liabilities you may incur if you receive frequent flyer miles from employer-paid business travel. You’ll want to carefully look at what kinds of exchanges will get you what you want. For example, you may be able to earn an all-inclusive destination vacation package in a shorter period then it would take you to accumulate the miles necessary for airfare to the same vacation spot. Make sure you look at the rewards offered by both points and miles and assess both in terms of dollars and time spent to earn the trips you want.

As part of this response, your blood pressure and cortisol levels will drop.  Practice deep breathing by taking in a slow, deep breath so that you fill up your entire lung.

Mindfulness is the technique of living in the present moment and taking your focus away from regrets about the past and fears about the future. Mindfulness can be incorporated into every aspect of your daily life. You can practice mindfulness when you are exercising, eating, working, talking, or reading. Mindfulness research has shown that this practice reduces stress by decreasing rumination. Mindfulness also improves memory, focus, and satisfaction in relationships. To practice mindfulness, focus on your senses and let worries or thoughts about obligations float in and then out of your awareness. Do not linger on any one thought. Instead, try to observe them and then let them pass. Practicing yoga religiously changes the chemical patterns in the body and triggers natural relaxation responses by the body.
