I have a semi-dwarf blood orange tree which was about 3 years old when I purchased it(three years ago). I fertilize it in Feb and Sept with Citrus food however it will not blossom. It has not had one blossom yet. The tree appears healthy, leaves are good in color it produces new growth every year, but it will not blossom. Is there any thing I can do to force it to blossom? FYI, I have a Lemon and Orange tree also and they both fruit profusely and all three are with in close proximity to each other in my yard (with in a 15 foot distance of each other and same exposure to sun) Anyone have any ideas???? Thanks!

i"m having the same problem with my orange tree. i don't know how to get it to bloom.

As Obywan suggests, stressing the tree can help initiate blooming. If the tree is perfectly happy and 'thinks ' it's gonna live forever, then there's no rush to create fruit and therefore seed. So drying it out would stress the plant and shock it into flowering.

Ever notice how the young citrus in nurseries always have a couple of fruit on them? It's because they are constantly stressed. They dry out too much and then get a drink. They heat up and cool down, they get blown over in the wind etc. They 'think' they're gonna die any minute. So they produce offspring.

Then you take 'em home and treat them beautifully and tuck 'em in to bed every night and they decide they just want to be the biggest, baddest fruit tree on the planet and don't need to worry about fruiting because they are invincible. SO you may need to remind them that they are not.

I've also heard that a good whack on the trunk with the back of an axe has a similar effect. Basically frightens the bejesus out of the tree and probably triggers some chemical release or similar which starts the process. (Sort of like a semi serious accident wakes us up to the time we waste and can jolt the most relaxed of people into a flurry of activity).
I'd love to know if it works.

The secret is the soil.

I'm so glad I stumbled onto this string. I don't have any fruit trees but I did notice the volunteer portulaca came up looking much nicer than the ones I had in the garden. And the volunteers were being walked on mowed and basically abused or so I thought.
