clemantis tips on wilt?
Dear Pat,
If fungal infection is suspected, cut out all wilted stems back to healthy (non-stained) tissue
and promptly destroy the affected material to prevent it from contaminating the soil.
New healthy shoots may be formed at ground level.

what roses would you recommend growing for the valley areas?
Thank You,
Clueless garden grower
Dear Clueless,
There are many valleys in the US and internationally. What area are you referring to in order
for me to be more helpful to you?
Many thanks

Hello, I live in Vail, AZ. I planted some sweet potato slips in late May.
I’ve noticed that my vines are flowering and not looking real good anymore. How
do I know when they are ready to harvest and how do I do that? What is the
differance between a vining plant and a bush plant? Thanks so much for any help
you can give.
Dear Susan,
The sweet potato vine is an aggressive fine but can have problems with white flies
and fungal problems. Starting the plants off in a good potting soil is usually wise.
Some people like yellow sticky traps to catch white flies which you might find
available at local nursery/garden supply stores. Harvesting takes normally about
140 days from start to harvest. Rake up or pitch fork tilling up the soil where the
sweet potatoes have grown.
A vining plants tend to have long stems or tendrils that help them attach to either a
trellis or another structure. Bush plants typically stay compact growing in one area.

How do I start a muscadine vine with seed?
Dear Rhonda,
Muscadine seeds should give you something close to the parent plant. Muscadines
by their very nature are a wild type growing grape with a thicker, chewier skin than
some of the more refined grapes. Take the seed and plant in a good potting soil
about 1/4 inch deep, keep it moist and plant into a container as they sprout and
grow larger.

What is the best way to start ginko seed? I am a highschool student who is
looking to grow this wonderful specimen, but am having difficulty finding the
seed. And the seed that I found is almost $2 for 4 or 5 seeds.where else could i
look to find the seed.
On another note where could I find some Plumeria seed, and are there any
tricks or things that they require to germinate.
Thank You for reading my message,
Dakota
Dear Dakota:
The gingko seeds are rare, so spending a few dollars for seeds is not uncommon.
You will not find these seeds amoung the cheaper or more common seeds at a nursery.
Plumerias should be cultivated from a cutting, this will make it true to the variety.
Most seedlings will not give you a plant that will grow like the mother plant.
Although after flowering, Plumerias will have large looking seed pods that will
contain numerous seeds. If you just want to be “Johnny Appleseed of Plumerias”
Happy growing with these.

My hibuscus bushes (verigated as well as regular ones) have been thriving;
however, some have now developed shriveled up leaves with black on them, as well
as some white stuff on them, which seems to be killing them. What is causing
this, and what can be done to treat it?
Dear Joyce:
No doubt the black is caused by scale. Might be mealy bug or cottony cushion scale.
This black sooty mold grows from the insects excretion. Find an insecticide that
labels itself for hibiscus. This may take a couple of applications used according to
label instructions.

Ok…so I don’t have bees and I know I have to polinate the tomato plants. The
web video’s show how to, but not how often. Could you please let me know how
often I need to do this? Thank you
Dear Peggy:
If you wish to hand pollinate at least once weekly take a small paint brush and touch
gently from one flower to another. You may want to buzz like a bee to get into the
character. Happy buzzing.

what are knockout roses? what re feeding requirements? can they be in same
fowerbed with daylillies
Dear Pam:
Knockout roses are a relatively new bush rose that have become very popular
partly because they are resistant to black spot. This is a major fungal problem
with roses. Like most roses they should be fed on a constant feed program
during the growing season. In general, this means a light application monthly.
Yes, they can be planted in the same bed as daylilies. Give them some space
between because the knockouts will grow larger than the lilies.

Years ago you did a soil analasys of my soil at which time you mentioned that a
large oak my have a disease because of a dark weeping substance from the trunk.
I failed to record what disease you diagnosed. Recently a limb twisted and fell
out of the center of the tree. What was the disease? Could the tree live longer
or should I have it drastically trimmed or removed?
Dear Sandy:
This must have been quite some time ago, although I do remember you.
I recommend getting a free estimate by Pinellas Tree Service and ask for Dale or John, who
are both Certified Arborist. Be sure to watch on CBS, Channel 10 WTSP on Sundays at 8am the
Ask Mr Greenthumb Show.

My neighbor helped me put in my tomatoes this year as I have been ill. He
watered the leaves. I told him not to. This morning they are completely all
wilted. Can I save them?
Dear Millard:
Perhaps, the biggest problem with a lot of moisture on tomato leaves is the increase
chance of fungus problems. Treating with a general fungicide listed for tomatoes on a
weekly basis should help. Hope you feel better.
My best,
Stan
