Rosemary Tips to Encourage Flower Blooms

 

I have a four year old  rosemary plant that is thriving but its not blooming.  I would really like it to bloom this year. A friend of mine has a “green thumb” and everything that she plants thrives and blooms so I decided to ask her why my rosemary wasn't flowering.  Here are a few of her tips to encourage flowering.

Sunlight is a factor.  Rosemary loves full sun and needs at least six to 8 hours of sunlight daily.  The hotter and the dryer the better.  My rosemary is grown in a container and was on the patio where it was partial shade in the afternoon so I moved it to an area where I knew there would be ample sunlight.

The only time I cut my rosemary is when I need a sprig for cooking.  I usually take a new stem from the bottom leaving the top and sides full.   Pruning too much in the spring is a good way to remove flower buds before they bloom.

Rosemary thrives in light soil that drains well.  Heavy soil that is non draining  will prevent flowering.

Fertilizing I use Spray n Grow in the spring  but other than that all I do is water my rosemary when soil is dry.  I grow rosemary in a container and the soil dries out quicker than in the ground so I water my rosemary once a day or when the soil is dry to the touch.

Rosemary is not a fan of fertilization as too much nitrogen will encourage a leafy bushy growth but limits flower production.

The age of the rosemary matters.  Rosemary needs at least five years to bloom.  So my plant needs more time and more sun.
