In one sentence, describe what the following article is about:

Hyacinth bulbs are typically sold in bundles of 3, and there are often deals when you buy multiple bundles at once. Bundles of hyacinth bulbs that are not pre-chilled usually cost $5-$7. Bundles of hyacinth bulbs that are pre chilled usually cost $12-$15. All hyacinths need a cooling period of 12-14 weeks to develop an adequate root system, otherwise they will not properly grow. If you cannot find pre-chilled hyacinth bulbs, this step is absolutely vital.  Store your bulbs in a dark area with temperatures between 35-45º Fahrenheit. Great examples of these locations include fridges, outdoor sheds, garages, or even potted damp sand. Be careful when storing your bulbs in the fridge. Certain fruits produce ethylene gas that will cause your hyacinth bulbs to rot and/or become sterile. If you decide to cool your bulbs in the fridge, don’t place any fruit in the fridge during the cooling process.  Don’t expose bulbs to freezing temperatures, otherwise they will become damaged. Wear gloves when handling hyacinth bulbs, as they can cause a skin irritation. Most floral and garden shops sell pre-chilled hyacinth bulbs, so be sure to ask for them when you're shopping. Buying pre-chilled bulbs will speed up your hyacinth growing process by 8-12 weeks. Pre-chilled hyacinth bulbs can sometimes be a bit more expensive than the non-chilled bulbs, but the time they'll save you will be well with the extra cost.

Summary:
Buy hyacinth bulbs from your local floral or garden shop. Cool your hyacinth bulbs before planting them. Purchase pre-chilled hyacinth bulbs to speed up the process.
