Well its answer your
gardening questions week, so let’s take a look at more of your most popular
questions. Like this one- I planted ornamental sweet potato vines this
year, and as we were digging them up for the end of the season, we found
large potato like tubers. What are they, and if they’re sweet potatoes, can
we eat them?
That’s exactly what they
are…sweet potatoes. That’s why these vines are so heat and drought
tolerant….they store water in the tubers. And yes, they are edible, but
they won’t taste like the sweet potatoes you eat on Thanksgiving. They’re
very bland, but they are very edible.
Here’s another popular
question which usually comes up earlier in the fall, but just now becoming a
popular one. The needles on my evergreens are yellowing on the inside of
the plant and falling off! Is my pine dieing?
Nope – The shedding of
inner needles in the fall is a very common process of many evergreens,
especially pines. They’ll shed needles up to this years new growth, where
spruce will shed needles from 3-4 years ago growth. As long as the
yellowing needles are just inner needles – no problem – but if they shed to
the ends of the branches, that is definitely not a good thing!
And here’s a question
that seems to really confuse people. When is the best time to winter
mulch? And the answer, winter mulch when winter gets here. We want the
soil to be frozen, or at least below 40 degrees before we winter mulch. The
idea is to keep the ground cold at that temperature. So wait to winter
mulch, until the soil gets much, much colder. |
