春季是植株摘心的最佳时机，通常是在新叶子发芽时进行操作。对于新的生长小苗，不宜等待到九月以后再摘心，否则可能会影响植株的开花。此外，也可以选择在植株长势较好时进行摘心，这样摘掉的花枝会更多，修剪后也更美观。
在摘心后进行剪枝时，应该修剪过长的枝条，并且将顶部新长的芽剪掉，这样可以促进旁边枝条的生长。如果植株过高，整体外观会显得不协调，因此摘顶后要进行修剪工作。
完成摘顶和修剪后，应该适量施肥，以促进周围枝条的生长。在摘心时，可以一并剪掉干枯的枝叶和密集的枝条。
注意事项：
1. Spring is generally the time to top the plants. It is usually done when the new leaves start to sprout. For new seedlings, it is best not to wait until September or later to top them, as it may affect the flowering of the plants. Additionally, topping can also be done when the plants are growing well, as this can result in more branches and a more aesthetically pleasing appearance after pruning.
When pruning after topping, trim any excessively long branches and remove the new shoots at the top. This can promote the growth of the surrounding branches. If the plant grows too tall, it will appear unbalanced, so it is important to do a proper trimming after topping.
After topping and pruning, apply a small amount of fertilizer to encourage the growth of the surrounding branches. When topping the plants, it is also advisable to remove any dry branches or dense branches.
