The Facts

• When a rose will bloom depends on a multitude of factors, all of which need to be correct in order for the rose to have the best chance of blooming. Altering one or more of the requirements can result in a later bloom or even no blooming at all, so care and attention to detail should be taken when growing roses.
  
  

Types

• Most roses bloom in spring or summer but the exact season depends on several factors, including the type of roses you have planted. Some species, such as the red Knock Out rose and the Rosa gymnocarpa, will bloom in spring. Others, such as the International Herald Tribune, bloom in the winter; although if you are growing them outside of a tropical location you may find winter roses bloom better if grown indoors.
  
  

Location

• Because rose blooming depends so heavily on the weather, the location of your rose garden is especially important. Attempting to grow roses in a cold, dark environment is less likely to yield favorable results than placing the garden in a sunny location in a temperate climate. Sunlight is very important to rose blooming, so plan ahead when laying out your flower beds.
  
  

Water

• Roses need an inch or so of water on a weekly basis when they are growing, so the soil should be moist in the months prior to blooming. Do not overwater, however, as roses die easily in soggy soil. With this in mind, pay close attention to the soil in the months leading up to the standard blooming date for your roses, as too much or too little water will stop your roses from blooming.
