Greetings
gardeners!
Wow, in the
Chicago area, we are in a terrific weather pattern!
This should continue
until about April 20th, and then gradually shift to
cloudier conditions and above normal
rainfall through the month of May.
It's a great time
to work the soil, but it's still too early to put
out most plants. It's ok
to buy the plants now, while the selection is good,
but don't plant them until well after
Mothers Day, or better yet, close to Memorial Day.
The cool season plants, like pansies,
are fine to put out. They enjoy this weather. Same
with the cool season veggies. Trees
and shrubs can be planted now, but actually autumn
is a better time. Planting in the
spring brings more top growth, and planting in the
autumn brings more root growth.
Grass seed is the
same way. It's ok to seed now, but the seeds will
become two month
old baby grass plants going into summer, which is
really hard on them. The root system
will be poorly developed because spring is a top
growth season. Also, it takes twelve
months for grass seed to mature its roots and
shoots. If we seed now, it's normal for
some of it to die off during the summer. It's normal
to lose as much as 50% of the new
grass, but, well, it's 50% more than you had before!
Just touch up the seed again in
September and THAT grass will probably make it.
Autumn is definitely the best time
for planting and seeding but it's hard to look at a
bare spot all summer! Just don't feel
bad and blame your black thumb if plants die in the
summer.
A word about
mushroom compost; DON'T USE IT!! It makes trouble
everywhere it goes.
Mushroom compost is aged horse manure and is sky
high in sodium and phosphorus.
Both of these will make a lot of trouble in our
soils. The high sodium will dry stress
the plants in summer as well as encourage a lot of
diseases. Roses will get more black
spots, phlox will get more powdery mildew, annuals
will get pythium (rot), tomatoes
will get verticillium wilt and on and on and on. It
ain't nuthin but trouble. All the
manures have this effect. I put goldfish water on my
house plants and THEY got
mealy bugs and brown spots on the leaves! As soon as
I stopped, the bugs went
away and the brown spots stopped spreading.
Composting manure has to be done a
certain way or it makes a lot of trouble. Sure we
get great growth, but not health.
The high sodium makes cells that are waterlogged but
poorly mineralized and this
invites the diseases and insects.
Also, when
phosphorus becomes excessive in the soil, it grabs
micronutrients and
locks them up and won't release them. We need the
micronutrients to give deep
green color to the leaves (iron and manganese) and
also for the plant's own immune
system (copper, zinc and boron) to fight diseases.
Without the micro's we're in
a heep of trouble!
So what should we
use for a soil amendment? Aged wood chips (mulch)
are the
best. It makes great crumbs in the soil. Just add
some alfalfa and bone meal for
food value and now we are looking at some really
happy plants! The best wood
chips to use are pine bark (fines), hard wood mulch
and the free chips from the
tree companies. Some times the tree chips are
available as double ground, which
means they are run through the chipper machine twice
-- that stuff is great. Here,
in Wheaton, I can get double ground chips for $15
per yard plus delivery. Good stuff.
In the Chicago area, aged pine bark fines are
available in bags called "Black Forest
Soil Conditioner". Black Forest makes potting soils
as well as soil conditioners and
all their products work extremely well. Email me if
you have trouble finding some
in your area. Please stay away from cedar and
cypress mulch. It is not good for
the soil.
I see dandelions
are coming on like freight trains so we will talk
about them next
time. And it's not what you think!
Happy gardening!
