By 2050, Earth’s population is expected to rise to 10 billion, while the resources on the planet continue to shrink. Researchers in the Netherlands are experimenting with one way to feed more people with less: growing crops indoors. NewsHour Weekend’s Ivette Feliciano takes a look at how indoor farming could shift our relationship with food.
Tips to care for roses across climate zones

Hybrid tea roses benefit from heavy pruning in winter. Shrub and groundcover roses need only shaping or light shearing. Both techniques are detailed below.
PRUNING HYBRID TEA ROSES
Remove all dead wood and all weak, twiggy branches. Make cuts flush with the bud union (the swelling at the base of the plant).
Cut all branches that cross through the center. This opens up the plant and gives it a vase shape. In hot climates, some rosarians just shorten center-crossing branches, so leaves will shade the bud union from the scorching summer sun.
