David Robson says planting the root ball this way will improve growth.

罗宾逊表示，通过这个方式种植后将加速植物生长。

With a newly planted tree, the roots have not yet spread out from the root ball.

对于一棵新种植的树，它的根尚未从根球中散开。

So maybe butterfly it first and then measure how tall your root ball is. Then dig your hole.

所以，先将根系切瓣，然后测量一下高度，然后再挖坑。

But you do have to remember by butterflying, you are cutting down the overall height of that root ball.

但是你必须记住，通过切瓣降低了球根系的整体高度。

So his advice is to pull the plant out of the container, then cut the bottom half of the root ball into four parts.

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。
