I have a small potted bougainvillea. How much fertilizer can one plant use in a couple of seasons, or for the shelf life of the bag? 2 pounds? 10?

For one potted plant, usage will be minimal, maybe a teaspoon per month, if that. I would get the smallest bag available and buy more bougainvillea plants. They're great - very eat to grow.

How often and how much does everyone water their bougainvilleas?

On Bgi’s web page, there are care tips about watering and fertilizing that were helpful to me.

We have a large bougainvillea that covers the side of our garage. Our gardener trims it back every other month. Is that too much? It shows brown stems

I can't say whether it is too much because I like to let my grow, but I've noticed my gardener trims it back maybe once or twice a year, so I'm going with that. Check online to see guidelines. I do love this fertilizer. My bush stopped flowering after 10 years of beautiful blooms. It responded immediately to the fertilizer and don't overwater.

How do you apply to a bougainvillea that's 3 stories high & 20' across w/ plants growing under the canopy & half the roots under cement?

If its that big, its probably got its own source of nutrition. You're fine. My family's bougainvillea is the same way and its a chore just to trim that monster down every year. One year we found out it had grown roots into the sewer line coming out of our house. We had to dig that whole thing up and replace the pipe.

It really works

This is amazing. I ordered a Bougainvillea plant and was barely making it and once I applied the product it started growing. This is about a 2 month difference. It has not bloomed yet.

Yes. It works. Bougainvillea like to be fed!

The bougainvillea I enjoy are always in pots and need food. If fed regularly smaller amounts, the blooms (bracts) are abundant and constant. Prune frequently after bloom flush and fertilize and you’ll be delighted. I like that it is organic and designed for this specific use. Easy!

It works!

This is the only product i've seen/used that actually produces vibrant colorful blooms! I've used many other miracle grow bloom busters but for some reason this is the only one that works. I follow the tips of letting plant completely dry before next watering and my plants are gorgeous .

Best Bougainvillea Buy!

I was hesitant due to price but this is the best. Yellow bougainvillea hadn't bloomed for 3 years. After application, growth was tremendous. Easy to use, a little goes a long way!

Works Great Year after Year

I buy this every year for my inground bougainvilleas in San Antonio TX. Plants freeze back every year… but will grow up to 15 ft high with this fertilizer every year…full of blooms. Easy to use…a little goes a long way.
