They might see the yellow blooms on a forsythia bush -- one of the first signs of spring -- and decide to plant one. But he says most ornamentals are better to plant just before their leaves open.
奥拉西是马里兰州霍华德县的园艺顾问。多年的经验使他了解到，人们通常在看到开花的观赏植物之后决定自己种植。他们可能看到一株连翘上开出黄色的花朵——这是春天到来的最初迹象——然后决定种植连翘。但是他表示，大部分观赏植物应该在叶子长出之前种植。
Some ornamentals and other plants are sold with their roots in a ball of dirt held together with burlap. But David Robson of the University of Illinois Extension says more and more plants are grown in containers. (2)_____________一些观赏植物和其他植物出售时根部都埋在麻袋包紧的泥土中。但是伊利诺伊州推广大学的大卫·罗宾逊（David Robson）表示，越来越多的植物种在容器中，这样更方便运输。
However, the roots may become encircled by growing around and around in the pot. So his advice is to pull the plant out of the container, then cut the bottom half of the root ball into four parts.
然而，随着植物在容器中不断生长，其根部可能会缠绕在一起。所以，他建议将植物从容器中取出来，将底下一半的球状根系切成四部分。
