Bulbs can be classified into spring flowering bulbs or summer flowering bulbs. Another way to classify bulbs to use in Illinois would be spring-blooming bulbs and tender summer bulbs.
Summer flowering bulbs (soft bulbs) die when the temperature is low. They should be planted in the spring when there is no longer any chance that the soil will freeze. They should be removed from the ground during the fall after the first frost that fades the foliage and should be stored during the winter.More news: Ecclesiastic 22 DHH - The fool and the lazy - The lazy one is - Bible Gateway
Spring flowering bulbs (bulbs resistant) such as tulips, crocus, need a cold period during the winter to bloom. These bulbs are planted and develop a root system in the fall and bloom during the spring. Illinois temperatures meet these cooling requirements as they are cool enough during the winter. For example, tulips need 12 weeks or more of cold temperatures. If the spring bulbs will be forced indoors, make sure they have been cooled beforehand, otherwise they will not bloom.
It is important to select good quality bulbs. The factors to consider are size and firmness. Larger bulbs produce larger flowers. Choose bulbs that are firm and have no signs of rot or any other sign of disease.
Bulbs can be obtained primarily through three sources: mail order companies, local nurseries, and convenience stores. discount. In general, those who offer more variety are those who sell bulbs by catalog and then send them by mail. The disadvantage of mail order is that the buyer does not know how the bulb will look until it receives it. It is therefore advisable to buy from reputable companies that you or someone you know has used successfully.
Once you get the bulbs, either from a local source or by mail, you should plant them as soon as possible. If it is not possible to plant the bulbs immediately, keep them cold until you plant them. The storage temperature prior to planting should range from 50 ° F to 60 ° F. Do not store bulbs near ripe fruits as they may produce ethylene. Ethylene produces flowering problems, especially in tulips.
