Why my periwinkle and portulaca always dying??
Susan Roger
are giving too much water and not enough sun!! Good luck, Susie

I'm a novice in gardening.
Anyone got any idea why my periwinkle only lives 14 days after sowing??
The plant seems to dried up every death... I do water them everyday and
they receive morning sunlight at least 1 hours everyday.
Have managed to sow Sunflower and Portulaca, finally got one sunflower
living and portulaca having the same fate with the periwinkle.

Both periwinkle and moss roses are partial to warm and somewhat dry
growing conditions. My guess would be with only one hour of sunlight
that the plants are not able to use the water available before more is
added. If this were true, it is likely the roots or stem would rot.
Keep trying.

portulaca like full, hot sun, and like to be on the dry side.

(1) plant them too early, before it is truly warm enough, (2) plant them
in areas of shade (they are not impatiens), and/or (3) keep them too
wet. They are very prone to diseases which decimate them under these
circumstances! Note that these get 1 hour of sun and are watered daily!
No Way, Jose!!!

Both of these are pretty drainage sensitive and do not need much water.
If you have a slow draining soil they will get waterlogged and develop
rot. They also both need lots of sun. So make sure your soil has good
drainage (not clay, use a good draining mix with some sand or other
amendment) and cut back on watering! THey do not need much water.
Also, try purslane instead of portulaca, it seems to be less drainage
sensitive and has similar flowers.....
Good Luck.

... if I'm not mistaken, the original poster is in Singapore. This may influence
your answers.
I think it will be warm enough, but yes - too wet and not enough sun.

water and fertilized properly.. Some of them just looked awful this year.
I'm going to do a soil sample. And check the ground after it frosts
(which will be any day)..The good ones I've put in the greenhouse already.
They were ok.
There might be a pest eating at the roots of those sickly ones. I
don't want to keep them.... If I find anything, I'll let you know...

flowers, that does indeed grow well in shade. I'm assuming that since
he/she sows these along with sunflower and portulaca, he/she is
referring to Catharanthus roseus, periwinkle.

fungus that kills them. You'll see cankers on the stems, usually at the
base of the plant, sometimes higher. But the plant starts to wilt and
dies from lack of water getting past that canker. Since it is soil
borne, you shouldn't plant periwinkles there for a long time. (I don't
know what that time is.) I had it last year, wiped out 5 flats. Some of
them had a chance to reseed before they died and came up this year..they
eventually succumbed, too.

just plantwd over 100 vinca minor plants in the shade and would be in
big trouble if they didn't like it there!

Oh, dear, I assumed we were talking Vinca major, which is
also called periwinkle and does very well in sun.

except that major is larger and grows even more vigorously than minor. I
have never figured out why these plants all got called periwinkle. Which
just shows to go you, the absolute need for the botanical name! (Which
is what I think you, with your delightful sense of humor, were pointing
out! Am I correct???)

Well, yeah, guilty as charged [and humming "Hail, Botanical!
Bontanical Rules the Wabe!"]. ;-D
But beyond that, V. minor is perennial here, while V. major
gets treated as an annual. Major really does do better in
sun here than minor, but it also likes it moist. If V.
major and portulaca, which likes it dry, are planted
together and both are doing poorly (which, I think was the
original problem) then maybe neither is getting the right
amount of water.
I don't know Catharanthus roseus -- what are its habits?
Elsie
not Vinca major or minor. (here, they're both evergreen). Catharanthus
is a reseeding annual, used as a bedding plant. The old variety flower
was white with a dark pink eye, then pure white, white with yellow eye,
bright pink, and now there are all kinds of colors - looking like
impatiens - beautiful. Some of the selections are 'Polka Dot', Little
Blanche', 'Pretty in Pink', 'Pretty in Rose' - there are lots. I know
you know this plant. It is very common, sold in nurseries and Walmarts,
etc., everywhere. I wonder if you know it by a different name - maybe
Vinca rosea? Madagascar periwinkle??
To the original poster - Hong Chin Siong - for our sakes, which plant
were you referring to? Please let us know!

Uh oh. Found "Catharenthus" listed in the index of a
Seymour's Select catalog. Went to the page where I found
the heading "Vinca" and all of the varieties you mention --
and not one word about "Catharenthus". Yes, I have seen
this plant, but it's always been labeled "vinca". I assumed
that it must be V. major (cuz it ain't V. minor). Now I'm
wondering if I've ever actually seen major at all.
My brain is beginning to hurt again and I think I need
another espresso fix. Later... :-O

You may not have seen Vinca major; it's not as cold hardy as minor. But
it's just more of the same only bigger and pushier. Minor is just a
dwarf variety of major.

Well, I guess I'll have to cross that one off my life list.
I've never seen major up close and personal! Now is the
annual's real (or at least current) name V. rosea or C.
rosea?

The 'annual' is Catharanthus roseus, aka Vinca rosea. It really is a
tender perennial hardy only into USDA Zone 9. BTW, both catharanthus
and vinca are in the family Apocynacae, with the vincas native to
Europe and catharanthus native to Madagascar. As Elsie noted, V.major
is less tolerant of cold than is V.minor. Further, V.major is more
tolerant of heat and humidity than V.minor. In NY you haven't seen
V.major, and I in (hot and humid) SE Louisiana haven't seen V.minor.
C.roseus does great here as an annual, and self-sows most of the time
(it tends to revert to the wild form, though).

Harold, central Louisiana here... so will I have a problem with
V.minor here? Will I have to plant major instead? Was thinking of
vinca minor as a ground cover....
