How long does it take for a geranium plant to grow?

Sometimes it takes a little while for the plant to be established before it starts to form buds. Once it's been planted for a week, it's safe to fertilize. Geraniums are heavy feeders, and it's essential to fertilize often (once every 1 or 2 weeks) in order to promote flowering. We know that geraniums need sun and can often tolerate some shade. However, they must have plenty of light in order to produce flowers. Make sure they are in open, airy spaces, not shaded by trees, for instance. Lastly, regular watering is always necessary for continuous, all-around growth. Sun, water, fertilize! some take weeks and others months !!
