crabgrass control

Organic crabgrass control, weather report for April/May

Hi Everybody!

Here is a  reminder of what my weathercaster, Nancy,
wrote for April 2013;

April will have more clouds than sun. There should be frequent drizzle or light rains but thunderstorms could quickly turn severe, with strong winds, heavy rain or even thunder snow. Temperatures fluctuate wildly, with a couple of isolated heat spikes in the middle of the month. However, there’s still the possibility of light snow through April 21, with lows frequently in the 30s. The big warm-up finally happens near April 22.

And for May, 2013

Dreary (cloudy/light rain) days alternate with sunny days in a typical springtime weather pattern.  Heat spikes remind us that summer is near.  Thunderstorms that do form could quickly turn severe.


********************

So May looks similar to April with warmer temperatures.

The overnight temperatures that Nancy is forecasting are all above 40 degrees so we gardeners will be able to put our plants in the ground the end of April.  The official frost free date for the Western Suburbs is May 31 with most people planting their gardens after Mother's Day and protecting the plants when needed.


********************

Little by little our lawns are greening up.  The best way to control crabgrass is with gypsum.  Crabgrass comes up from seed every year.  Crabgrass seed germinates when the soil temperature is above 60 degrees for three consecutive days.  This usually doesn't happen until June so applying a chemical crabgrass preventer right now is not a good idea.  The chemical will wear off in about 6 weeks so you don't really get much control and anyway it's too cold for the seed to germinate.

Here is a secret that no one knows; Crabgrass only germinates where there is salt.  Gypsum neutralizes salt.  It's even on the bag of gypsum!  Go to Home Depot and find the pallet of gypsum in the gardening section and read the label.  It will say 1) neutralizes road salt  2) neutralizes dog urine spots and  3) softens clay soils.

What's not to like?  The amount of gypsum to use to neutralize road salt is on the bag but we usually do one 40# bag per 1,000 sq ft  and apply it out by the curb where the snow trucks push the snow.  We also apply a half bag of gypsum along each side of the driveway to neutralize the salt coming off our tires.


*************************

Here is a cute little trick that I use to know when the soil is warming up;  

Dandelions bloom when the soil temperature is between 50 and 55.

Fifty degrees is when the bacteria in the soil become active.  

So the trigger for dandelions to blossom is soil temperature.

Easter weather, Seeding, and Honey bees

Hi Everybody!

We hope you had a Happy Easter and enjoyed the taste of Spring that we had last weekend.

The date for Easter changes every year because it's based on the first full moon after the Equinox.

The four seasons are based on the four cardinal sun dates of Spring and Fall Equinox and Summer and Winter Solstice. 

Traditional and tribal cultures noticed, however, that the season didn't actually begin until it was "activated" by the full moon.  So Spring weather tends to appear around the time of the first full moon after the equinox.  

The Equinox was March 20 this year and the full moon was Wed, March 27 with Easter being the following Sunday.  Right on time, we had great temperatures altho a few clouds kept a chill in the air.

Results vary from year to year but this basic principle can be observed.


**************************

Now is a great time for sowing seeds.  The full moon in March is known as the "Seed Moon" because temperature, moisture and sunlight are working together in a powerful way.

Grass seeds won't germinate until they are touching soil.  We like to put down some topsoil on the brown patches and sprinkle seed onto it and then rake it in so the birds don't get it and to prevent the seed from drying out.


*************************


My friend Chris Saad has honey bees and he told me the bees are bringing in pollen from the soft maple trees which are flowering now.  That would be Silver Maple and  Red Maple.  These are always one of the first trees to flower in the Springtime and the bees are working the trees to get pollen which they use for food.  Pollen is high in protein and minerals and bees use these nutrients to grow their bodies.  Nectar is high in sugars which they use to fuel their activity but there is not a lot of nectar right now.


**********************


Chris is out and about applying organic lawn fertilizers now that the weather has warmed up a bit.  Feel free to contact him at pureprairieorganics@gmail.com to schedule a free estimate for professional feeding of your lawn and trees.  


Happy Gardening everybody and feel free to leave a comment or ask a question!

Dog urine spots, road salt, grubs and other brown spots in the lawn

Happy Spring Everyone!

Yesterday was March 20 and the wind chill was -4 degrees.  What is wrong with this picture?!

According to my weather friends, the quarter moon can be very windy.  I have noticed this in the past but it is not every month. On Tuesday we had a quarter moon with the moon in Gemini which is an air sign.  Wind on top of wind.  I think our peak gusts were about 35-40 mph.

Nancy McEwen says we won't really warm up until April 1.  Right now we are in a 30 degree - 20 degree weather pattern and April looks like a 50-30 and 60-40 pattern.  

That would be a nice warm up without getting too hot and making the plants go crazy.  Sometimes we are concerned that if the weather is extreme one way then it will flip and become extreme the other way.  

Kind of like last Spring where we had 5 days of 80 degree weather in March with 5 nights of 20 degree frost in April that froze all the blossoms on the tree fruits.

North America is still on track to have an extreme weather event on March 28-29 with a strong snow storm here in the Chicago area.  We may also get some winter storm on April 6 and that should be the end of it.


****************************************


Now is a great time to put down gypsum to neutralize road salt and to fix dog urine spots.  Call Chris if you need to save time and would like us to do it.  If you would like to do this yourself, gypsum is available at Home Depot and Menards and a 40# bag is about $6. We apply a 40# bag for every 1,000 sq ft of lawn area to neutralize the salt and urine.

Sugar also works for dog urine spots.  Put one or two handfuls of table sugar on each spot and let the rain water it in.

Spring is a great time to apply gypsum to the entire lawn.  It will soften the clay and help control lawn diseases which will show up in July.  

These lawn diseases are actually a fungi attacking the roots of the grass.  This fungi is the food for the grubs.  The advertising says the grubs eat the rots of the grass but that is not true.  Grubs eat the FUNGUS attacking the roots of the grass.  Control the fungus and we control the grubs.

Gypsum helps us control the fungus.

A spring application of gypsum gives it time to work before the brown spots show up in the Summer.  Once the brown spots show up it's too late so it's best to get on it early.  

If brown spots come in the summer then an application of gypsum and lime will stop it from spreading.

Gypsum and lime both contain calcium which is very important for plant health.  When plants are healthy they resist diseases naturally.

Summer temperatures are also important because it can put a lot of stress on the turf so feeding good nutrients like lime and gypsum help the plants prepare for this.

Plants are strong but we need to give them a chance by feeding them good nutrients.

Chemical lawn fertilizers lack the supporting minerals and carbs to make plants healthy.  The high nitrogen pushes plant growth but the cells are poorly mineralized and the lawns get sick in the summer because they lack the nutrients to protect themselves.

Our organic lawn applications have the minerals that help the plants be healthy.  Not 100% because weather and types of grasses make a big difference but we make your plants strong so when the high heat of summer comes then your lawn will be the last to brown and the first to recover.

I know it sounds crazy to talk about the high heat of summer when it is 12 degrees outside right now but the time to prepare our plants is now, in the Spring.

That's it for today....Contact Chris or myself if you have any questions and if you would like expert help for your lawn this year then call Chris at 630-649-1476 for an estimate for our lawn and tree feeding program and we will get your plants well fed and happy.

Happy gardening everybody!

Organic crabgrass control

Hi Everybody!

Did you know that there is crabgrass seed everywhere?

If crabgrass seed is everywhere then why doesn't it germinate and grow everywhere?

That's because crabgrass only germinates where there is salt.

Here in the Upper Midwest, crabgrass grows along the side of the road where the snow plows push the snow.  It also grows along the sides of the driveway where the salt melts off our tires.  Round Up breaks down to a high salt so if someone sprays Round Up then they may get some crabgrass germinating in that spot.

Gypsum neutralizes road salt.  Gypsum (calcium sulfate) is a better crabgrass control than the chemicals are.  The first year it may only reduce some of the crabgrass but by the second year it should be much more under control.  

For organic crabgrass control,  we recommend applying gypsum at Thanksgiving and Easter.  In the Chicago  area, that will work out to be before and after the snow season. 

Here in the Chicago area, we mix some lime with the gypsum (50-50) and it makes the gypsum work much better.  Adding a few pounds of table sugar also helps.

We don't worry about the pH of the soil...the microbes will take care of it for us.  The main thing is to get plenty of calcium in the soil.

Crabgrass also grows along the Gulf states(Mississippi, Louisiana)  as well as sandy areas like vacation spots.  This is because crabgrass will also grow in soils that are low in calcium and phosphorus and low in biology.

If you have sandy soil and crabgrass is growing everywhere then it is not worth it to try and control it.  Just mow it and call it good.  

If you are in the Western suburbs of Chicago,  call us (630-649-1476) and we will help you with your crabgrass problem.  Over time, we will correct the cause of the problem and  do it without the use of harmful chemicals.  Very cool!

Thank you for reading our blog and happy gardening!
