Bulb Rot

Tulips, daffodils, or other bulb plants that develop stunted, yellowed leaves, or fail to emerge in the spring may be suffering from bulb rot. Cool, soggy conditions can favor infection by certain soilborne plant pathogens. Several different fungi and bacteria may infect bulb tissue.

The Other Onions

The common garden onion (Allium cepa) is one of many edible onions. These other edible onions often produce more than one bulb per growing season. Some are perennials in the garden. The common names used for these edible onions can be confusing. Almost any onion that is grown for its green tops can be called bunching onions, scallions, or shallots. In addition, almost any onion that produces clusters of small underground or aboveground bulbs can be called multiplier onions. And finally, any onion that over winters well can be called a winter onion.
