: My problem is that my 6' trees are growing great but they will not produce flowers.
: I feed them with Miracle Grow but the have not produced any flowers.
: Does anyone know what I can do to help them?

: Thanks

Hi Steve and Suzie,

I ready both your posts, and though I'm not certain of the cause of the problem, I suspect the Miracle Grow has a lot to do with it. Miracle Grow and other synthetic fertilizers leave behind residual salts that accumulate over time and are like putting your plants on steroids. They can actually become exhausted over time. My suggestion is to flush the potted plants with lots of water and just let it run through to get rid of the salts. Let the plants rest for a month or two before fertilizing again. Then use a gentler natural fertilizer like fish emulsion or sea kelp. You could even add a tablespoon of milk (yup the stuff you put in coffee) to your watering can. The milk contains calcium and other vitamins and minerals that help with blooming.

Steve, you don't say if your plants are in the ground, but I suspect so. If so, try topdressing with compost for a more balanced fertilizer that will be gentler to your plants.

You both may also find some interesting reading here.
