I believe that the plant is Trichocereus pachanoi 'San Pedro' and have been watching these little puffs grow. But now they seem to have stopped growing and inside the cotton they feel hard. I have lots of these plants and none of them have grown any buds. Any thoughts? Thanks. Xuling

If the buds feel hard its a good sign as aborted buds just dry up into husks, i'd suggest giving more water and feeding it with a good low nitrogen fertiliser, this helps give it enough food to form the buds, which can take quite a lot out of the plant.

Thanks DMersh, I have been giving it water (all my cactus beds gets watered regularly) but haven't been giving it any fertilizer. I will do that. Xuling

The direct sunlight and heat might be making the buds abort also. Mine in Phoenix have never even budded and probably won't because of the excessive heat and sun.

T pachanoi grows at alitudes of 6000-12000ft in habitat from what i've read so maybe not surprising low desert heat is too much for it to flower.

Even here with none of that heat, those plants are very reluctant to flower. They make the furry buds, but that's as far as it goes. Still trying to tweak things to coax them into going further. It could be a matter of giving water at the right time during our dry summers.

I get many more buds than flowers, too. And sometimes the buds seem frozen for months before they bloom or dehisce.

Summer of 2011 we had a great flowering event here with I seem to remember some 60 - 70 blossoms in a single night with lesser numbers several nights either side of the big night .

This year masssive number of the "puffs " formed and we had a small event night of 20 some blossoms with a substantial number failing to develop fully . A small number of the remaining buds have dried up but there is still some 50 or so where they remain green and hard thogh still largely "puffs " with thier hair surrounding the buds . When they do prepare to bloom you will observe the bud extend some 4 plus inches from the puff ball over a period of a week or so . It will be obvious .

lonediver,
Are your San Pedro's shaded or in full sun?

I have but one San Pedro , it has some 15 plus arms on it . Most arms are 6 plus feet tall , at present it has been in full sun . I planted a honey mesquite not too far from it that will likely in the future offer it some shade from the worst of the western sun .

I found where the wife stashed some of the pics of the San Pedro blossoming last summer here ;

Seems a little late in the season but I see about 2 dozen or more buds that are starting to elongate and swell . Some 4 to 5 times thier dormant state . I could have more blossoms shortly .
