修剪绣球花

修剪绣球花 第一个, it's important to know that mophead hydrangeas do not have to be pruned back - ever - unless they are very old. Removing dead stems is the only pruning that must be done for the health of the plant, 这些可以在任何时候移除. 死花也可以随时移除. But if your hydrangea is getting much too large (or old), 你只需要修剪它, 使用以下方法之一. 使用方法一 if you have mophead or lacecap hydrangeas (these are the only type hydrangeas that are usually blue or pink) or if you have Oakleaf hydrangeas (leaves shaped like large oak leaves, 白色花朵). 使用方法二 if you have paniculatas (PeeGees) or “安娜贝拉” (arborescens). PeeGee和“安娜贝拉”都是白色的.

修剪:方法一

USE METHOD I FOR: Mophead and Lacecaps (macrophyllas - usually pink or blue) For Oakleaf hydrangeas (white blooms, 形状像橡树叶的叶子)

 

方法一总结: Prune these hydrangeas only in the summer BEFORE August (to be safe). Some experts believe these hydrangeas may be pruned even into August, but this might be risky. The hydrangeas may already have set their bloom buds for the next year. 方法我 是在老木头上盛开的绣球花吗. ("Old Wood" are stems that have been on the hydrangea since the summer before the current season. "New wood" are stems that developed on the plant during the current season) This group of hydrangeas produce flower buds on hydrangea stems around August, September or October for the following summer's blooms. 如果这些茎在秋天被移除(修剪), 冬天, 还是春天, 花蕾将被移除, and there may be little or no bloom the following summer (usually June/July for the northern hemisphere). Note that pruning is not the same thing as removing the dead blooms. (见下文“去除旧花”.") There exists a small group of mophead hydrangea that will bloom no matter when they are pruned. (“无尽的夏天”就是这种绣球花). Your garden center can tell you when you purchase a hydrangea if it is in this special category called "everbloomers.“但对于绝大多数绣球花来说, pruning after July will likely result in fewer blooms the next summer. HERE ARE CERTAIN INSTANCES WHEN PRUNING CAN BE HELPFUL: (1) All dead stems should be removed from hydrangeas every year. (2)植株至少5年之后, about 1/3 of the older (living) stems can be removed down to the ground each summer. 这将使植物恢复活力. (3)此外, if it becomes necessary to prune a plant to reduce its size, it may be cut back in June or July without harming the next year's bloom. But it will return almost immediately to it's former size. This is one reason why it's best to plant a hydrangea where it does not have to be pruned. 异常: For all mophead hydrangeas, the above method of pruning (方法我) will work very well. 然而, one may become confused when a neighbor or friend prunes his or her hydrangea at the "wrong" time, i.e. in the fall 还是春天, and then his hydrangea blooms just fine. 不像大多数毛头绣球花, there are a few that will regenerate the bloom buds they are cut off (destroyed). 这些绣球花被称为“菊芋”。. They seem to be found most abundantly in gardens in the northern regions of the U.S. 和加拿大. 因此, 在这些特殊的绣球花上, if the bloom buds are killed by frost or pruned off at the wrong time, they will regenerate the bloom bud and bloom as usual.

PRUNING: METHOD TWO For paniculata (such as PG and 'Limelight') and “安娜贝拉”

方法二 is 用于: H. 乔木(安娜贝拉型)和H. 绣球花. These types of hydrangeas bloom on new wood (new stems). It is a joy to grow these type hydrangeas because they are determined to bloom every single year, 不管别人怎么对待他们. The only time they cannot be pruned is in the spring (“安娜贝拉”) or in the summer (PG) when they are preparing to bloom. 许多人把篱笆围起来 安娜贝拉 and cut them within a few inches of the ground each fall so they will not be an eyesore during the 冬天. They will still bloom beautifully in the spring/summer, however this drastic pruning may not allow stems to increase in size, and they may need staking to hold up the large heads. 转到下一页 “安娜贝拉” for a more detailed description of the pros and cons of pruning this hydrangea to the ground. While at the “安娜贝拉” page, view a picture of Penny McHenry's “安娜贝拉” hedge. 圆锥花序(PG/Limelight型))可以在秋天、冬天或春天修剪. 然而, it is not necessary to prune them every year. It is suggested that one trim out crossing branches and those that do not contribute to an attractive form whenever necessary. Paniculata hydrangeas are the only hydrangeas that can be pruned into a tree-form. 如果有人想把一棵圆锥花序长成树, the developing trunk and main top branches should not be removed. If a panicultata that is trained into a tree-form is cut or broken off close to the ground, it will grow back as a shrub unless the training and pruning is started again from t
