When does spring begin? It all depends on where your spot on this planet hangs out. Since I?m in the Pacific Northwest (WA-USA), I?ll try to give you some information from a favorite gardener, who lives in this community, and is recognized as a garden authority in the Northwest and nationwide.
Ed Hume is his name, and I?m using info from his very good book ?Gardening with Ed Hume?. In his list of Annuals, his Planting Times are: Early Spring (March/April), Spring (April/May), Late Spring (Late May/June). His starting times for seedlings indoors are February or Early March. In his Perennial listings Flowering Times are: Spring Flowering, Summer Flowering, and Autumn Flowering. His planting times for Perennials indoors are late February, early March, for outdoors March to October. Mr. Hume has a line of seed packets that are distributed quite well through retail outlets in the area. He researches his product so that they will grow in this area, I use them with very good luck! On the back of his seed packets he offers a wealth of growing information, too.
Now, we go to an authority on greenhouse operation, his name is Shane Smith. He is founder and director of Cheyenne Botanic Gardens in Cheyenne, Wyoming (USA). For propagation of plants starting times he uses December/January, February/March/ April/May, June/July, August/September, October/November. For propagation of vegetables and fruits, etc. he goes by each month (January, February, March, etc) for planting times, growing times, and harvest times. His book is entitled ?Greenhouse Garden Companion?.
And we haven?t even started to talk about Fertilizer, Pruning, and other schedules.
All confusing ? VERY! Since all the information above is important to various gardeners, in whatever they are trying to accomplish, I would suggest that IdeasGuy use the categories he has come up with. And since you have to take into consideration all of the localized environmental impacts, you can break his terminology down, into the twelve months or part of those twelve months to mean what you need for data for each of your entries. After all, it?s to help the user (me) the way he uses that information. Decide on your localized ?times? and keep them as uniform as possible throughout your work. And if you are growing the plant, you can always edit your own copy to your own satisfaction.
After all, in most cases, they are all guidelines, not a firm action.
