Arie de Geus describes, in his book The Living Company (1997), how nothing is more important for a rose garden than how you prune the roses. The best way of pruning depends on the results you want to achieve. If you want the biggest and most glorious roses of the neighborhood you have to prune drastically. You have to cut each rose tree down to three stalks each. Each of those stalks can only keep only three rosebuds. Everything except these 9 rosebuds has to be cut down to get the maximum result: the biggest rose. This way of pruning is a strategy of little tolerance and tight control. You force the plant to make maximal use of the resources it has by forcing it to concentrate on its 'core business'. You can impress you neighbors that summer with the most spectacular rose. But if this turns out to be an unlucky year, you'll have late frost, end of April of in the beginning of May. This could create serious damage on the few remaining buds and could even cause the plant to die. In an unpredictable environment, pruning is risky and a strategy of high tolerance is wiser. You leave more stalks and more buds on each stalk. You may even keep buds which could only lead to very small roses. This way you are unlikely to get the biggest roses of the neighborhood but you'll increase your chances of getting roses each year. Furthermore, you'll stimulate a gradual renewal of the plant. By leaving younger and weaker stalks intact, you'll give them the chance to strengthen and to take over the role of the stronger stalks in later years. The tolerant strategy is less efficient and allows for weakness but has advantages in the long term.
