In warmer climates, where winter temperatures are not cold enough to chill bulbs, you'll need to pre-chill your bulbs before planting.
To pre-chill, leave bulbs in their bags and place them in a refrigerator. Be careful not to store bulbs near fruit, (especially apples) because ripening fruit gives off ethylene gas, which can damage or kill the flower inside the bulb.
Once bulbs have chilled, plant them at the coolest time of the year in your climate.
Most importantly, bulbs won't last till next season, so make sure to plant them!
