abound with electric-, gas- and
propane-powered heating sources.
Some systems will require venting.
You also will need to know what is
available and legal in your area.
Check to see if you need a building
permit for the greenhouse and any
accompanying heating elements.
Once the greenhouse is situated,
you can begin to add other items,
like benches, additional shelving,
hooks for tools, and even an
automated watering or misting
system.
Greenhouses take commitment,
but the reward is the chance to enjoy
gardening all year long.

Thinning grass a sign of several different diseases
MS –Thick grass is often a
hallmark of a healthy lawn. If grass
begins to thin, homeowners may feel
as though all the time and effort they
spent tending to their lawns was for
naught.
Thinning grass can be caused by
any number of things. And while it
might take a little effort to address,
thinning grass can be treated if
homeowners correctly identify that
cause of the problem.
• Leaf spot:the Center for
Agriculture, Food and the
Environment at the University of
Massachusetts Amherst notes that
leaf spot diseases affect both cool-
and warm-season turfgrasses.
Various fungi can cause leaf spot.
Symptoms and the timing of the
appearance of leaf spot will vary
depending on which fungi is causing
the problem. For example, bipolaris
sorokiniana, which affects grasses in
warm, wet summer months,
produces small spots that are dark
purple to black. Dreschslera poae is
another fungi that causes leaf spot,
and it also produces dark purple to
black spots.
However, it tends to appear in the
spring when the weather is cool and
moist. Understanding the different
fungi and when they typically strike
can help homeowners identify what
is causing their grass to thin. In such
situations, professional landscapers
can be invaluable resources as well.
• Stripe smut:the University of
Maryland Extension notes that stripe
smut primarily poses a threat to
Kentucky bluegrass that is older
than three years. Pale green streaks
that run parallel to the veins in the
leaves and leaf sheaths are
symptomatic of stripe smut, which
tends to be noticed in spring and fall,
when weather is cool.
As the disease progresses, stripes
turn black or a silvery gray, causing
the leaf blade to shred and curl.
After the blades have shred, they
turn brown and die. The grass thins
because stripe smut makes it
vulnerable to problems like drought.
• Ascochyta leaf blight:Lawns
suffering from ascochyta leaf blight
will become straw-coloured.
According to the lawn care and
pesticide experts at Ortho®, when a
lawn is affected by ascochyta leaf
blight, its healthy grass blades will
be mixed in with diseased grass
blades. Most prevalent in the spring,
this disease can affect grass at any
time during the growing season.
That’s because the ascochyta fungi
invade leaf blades through wounds,
such as those that can result from
mowing. Ortho® notes that dull
lawn mowers can contribute.
Various issues can cause grass
blades to thin. Working with a
landscape professional is a great
way to combat such issues before
they compromise the look of a
lawn.

If you cut me...
Like other organisms, grass is injured when it is cut. Every time a lawn is mowed, diseases
like ascochyta leaf blight can enter the plant through the cut. (MS photo)1-877-513-5333
