The best time to prune spring bloomers is as soon as the plant has bloomed out. On younger shrubs, prune branches back to nonflowering shoots or back to healthy buds pointing in the direction you want the shrub to grow -- typically away from the center. Always cut back diseased or weak stems to healthy wood. Disinfect the blades with a 10 percent solution of bleach between cuts to prevent spreading disease.
New Shrubs
Young, newly planted shrubs, require cutting back after their first bloom. The trim helps them to grow a stronger framework and bloom more profusely later. Some species, such as Forsythia Y intermedia or beautybush (Kolkwitzia amabilis), may not bloom heavily their first few years, but they still need weaker growth and wayward branches cut out; their main shoots should be trimmed to a strong bud or pair of buds.
Established Shrubs
Older shrubs can get out of shape and new growth slows down. Dead limbs can become diseased. Trim back to create new growth and remove all dead wood. You may sacrafice some blooms the following season, but it is well worth the trim in the coming years.
Exceptions to the Rule
Knowing your plants comes in handy when pruning. Some plants produce new shoots during the growing season but will not bloom the following season. Hydrangeas are one of those, therefore requiring minimal pruning. If you aren't sure when is the best time or how certain plants should be pruned, check it out on the internet or with your local agricultural extension agent.
Til next time,

Poppy we have an azelea bush that is, by what information we have gathered, around 50 years old. I have noticed that with even morderate and continous pruning, that has began diminishing its blooms. In the plant world is there such a thing as a plant growing old? I have tried to research it but havent really found any reliable information. I have noticed in irony, that a rose bush we have, which believe it or not is almost 70. It was planted by the original owners of our home. It never fails to produce beautiful flowers. We have even taken trimings to fill other spots within our rose garden. As you can see, it is a puzzling question. Looking forward to your response and oppinion.
