October advice

    Linn County Master Gardener Claire Smith submitted the following:

 

My 2008 Iowa State University Extension Service Garden Calendar—a plethora of recommendations and advice each month –suggests an October visit to a pumpkin patch for the perfect Jack-O-Lantern candidate.  My favorite daughter, son-in-law and granddaughter have enjoyed this family tradition for several years.   Now 7-year-old Catie has managed a larger specimen every year.   This year, 2-year-old Charlie will say “Me Too, Mommy” as he stubbornly grapples with as much pumpkin as he can manage to drag out of the patch.  Girly-girl Catie enjoys decorating, but not cleaning out the “innards”.  I’d bet my All-Boy Charlie will love every minute of the mess!   No kids at home?  No Grandkids around?  Go ahead!  Be a kid again, go visit a Pumpkin farm soon. 

                Other suggestions from the calendar for October are:

                                Continue to mow the lawn until the grass stops growing

                                Apply fertilizer to the lawn, but not to perennials or trees

                                Compost fall leaves

                                Plant spring flowering bulbs.

 

                                On that last note, here are some recommendations for brightening your days next spring:  Bulbs are usually inexpensive.

Follow the directions on the packages.

               

    Plant in mass:  four large and nine small bulbs per square foot.  The smaller the bulb, the larger the grouping should be. 

    Generally, bulbs should be planted at a depth of two to three times the height of the bulb.

   Place the bulb “tip” side up (that’s not the root side).  If in doubt, place the bulb on its side!

   Plant in well draining soil.

   Chicken wire placed under, around and on top of bulbs deter rodents. 

Water the area thoroughly and apply about 2” of mulch after the first frost. 

Apply fertilizer three times per year:  in the fall for the roots, in the spring when the sprouts first poke through and then when the flower dies.

   Deer tend to avoid daffodils, alliums, and snowdrops. 

Tulips and crocus seem to be the bulbs-of-choice.

               

So, after you’ve been to the pumpkin patch, go visit your favorite garden shop and get to planting.

Overseeding lawns

Richard Jauron, Horticulture Specialist at Iowa State University Extension, offers the following on overseeding lawns:

Healthy, well maintained lawns are attractive landscape additions.  Lawns in poor condition, however, are somewhat unsightly.  The poor condition of a lawn may be due to poor management, heat, drought, diseases, insects or other factors.  In severe cases, the existing lawn may have to be destroyed and a new one established on the site.  Lawns that contain over 50 percent desirable grasses can often be improved by overseeding.  

Overseeding is the sowing of grass seed into an existing lawn.  In Iowa, the best time to overseed a lawn is late summer (late August to mid-September).

Site Preparation

Good site preparation is necessary for successful overseeding.  If possible, identify and correct the problems causing the lawn to decline.  Overseeding may only be a temporary solution if these problems are not corrected. 

To reduce the competition from the established turfgrass, mow the lawn at a height of 1-1/2 to 2 inches.  Successful overseeding also requires good seed-to-soil contact.  Simply throwing or broadcasting seed over the lawn typically results in poor seed germination as much of the seed is resting on the thatch layer or soil surface.  Rakes, core aerators, vertical mowers, and slit seeders can be used to ensure good seed-to-soil contact. 

Overseeding Small Areas

Small areas can be prepared by gently raking the thin spots.  When raking, it’s necessary to break the soil surface without pulling out the existing turfgrass.  After raking, sow the seed by hand.  Then, work the seed into the soil by gently raking the areas a second time. 

Overseeding Large Areas

Large areas can be prepared by using a core aerator.  Core aerators are machines with hollow metal tubes or tines.  They remove plugs of soil when run over the lawn.  To prepare the site, go over the lawn three or four times with the core aerator.  When finished, there should be 20 to 40 holes per square foot.  Apply the seed with a drop seeder.  Afterward, drag the area with a piece of chain link fence or drag mat to break up the soil cores and mix the seed into the soil. 

It’s also possible to prepare the site with a vertical mower.  When run over the lawn, the knife-like blades of the vertical mower slice through the thatch and penetrate into the upper 1/4 to 1/2 inch of soil.  One or two passes should be sufficient.  Afterwards, remove any dislodged debris from the lawn.  Sow grass seed over the lawn with a drop seeder.  Work the seed into the soil by again going over the site with the vertical mower. 

Large areas also can be overseeded with a slit seeder.  A slit seeder makes small grooves in the soil and deposits the seed directly into the slits. 

Core aerators, vertical mowers and slit seeders can be rented at many garden centers and rental agencies.  If you would rather not do the work yourself, many professional lawn care companies can overseed your lawn. 

Post Seeding Care

Keep the seedbed moist with frequent, light applications of water.  It’s usually necessary to water at least once or twice a day.  Continue to mow the lawn at a height of 1-1/2 to 2 inches.  Mow the lawn frequently to reduce the competition from the established turfgrass.  When the new seedlings reach a height of 1-1/2 to 2 inches, gradually increase the mowing height over the next several weeks.  The final mowing height should be 2-1/2 to 3 inches.  Approximately six weeks after germination, fertilize the lawn by applying 1 pound of actual nitrogen per 1,000 square feet.  

When properly overseeded, a thin, scruffy-looking lawn can be turned into a thick, lush lawn in just a few weeks.

Lazy days of summer

The following is from Linn County Master Gardener Claire Smith:

 

LUV having the windows open!  LUV keeping the air conditioner off!  LUV sitting on the deck without bugs!  LUV having to mow the lawn only once a week!  It’s August.  Summer is winding down.  The cicadas are singing.  The robins are readying for their southern migration.  Soon we’ll experience the vibrant burst of burgundys and yellows and oranges.  School starts in a couple of weeks.  Are you ready for some football? 

            How are you going to tend your garden and yard for the rest of the lazy hazy days of August? 

Now is a great time to tour your yard looking for bare spaces or…….a good excuse to

  • create a new bed or add plants. How about peonies?  Choose a spot with sun and drainage.  Plant the “eye” (bud) about two inches deep.
  •  Or dig and divide your (or your neighbor’s—with their permission, of course) overgrown iris, poppies and other spring blooming perennials.  A good rule of thumb is to move spring blooming flowers in the fall and fall blooming flowers in the spring. 
  • Plant a tree!  Fall planting takes advantage of favorable soil temperatures and moisture conditions that promote the root growth needed to sustain plants through their critical first year in the landscape. 
  • It’s best not to prune now.  Pruning will stimulate unwanted late season growth.
  • Think fall flower arrangements.  Invest in a Burning Bush, a Bayberry Bush or a Red-twigged Dogwood.  All have colored stems that will stand out in dreary winter landscape. And those reddish branches create an outstanding compliment to fall groupings of gourds, pumpkins and dried flowers.
  • Mid-August through mid-September is the best time to repair, replace or start a new lawn.  Lawns with fifty percent or more weeds should be replaced.  Always purchase quality lawn seed.  All grass seed mixes should contain several varieties of bluegrass, fescue and rye grass.

So, get up off that couch.  Get out in the yard.  Enjoy this great time of the year.

Mowing tips

   The amount of rainfall we’ve received in Eastern Iowa this weekend alone has been incredible. For homeowners who like a green lawn, it’s a boon. Personally, I don’t mind letting my lawn go dormant to save on the weekly chore of mowing, but it doesn’t look like that will happen anytime soon.

 

   Richard Jauron, of Iowa State University’s Department of Horticulture, offers the following tips for those of us who will once again be getting the mowers out this week:

 

   Sound mowing practices are important during the summer months. Kentucky bluegrass lawns should be mowed at a height of 3 to 3.5 inches during the summer months. (During cool weather in spring and fall, bluegrass lawns should be mowed at a height of 2.5 to 3 inches.) The additional leaf area during summer shades and cools the crowns of the turfgrass plants. Extremely high temperatures at crown level can kill the turfgrass.

When mowing the lawn, never remove more than one-third of the total leaf area at any one time. Accordingly, a lawn being mowed at a height of 3 inches should be cut when it reaches a height of 4.5 inches. Removing more than one-third of the leaf area weakens the turfgrass and reduces its ability to withstand additional environmental stresses. Weakened turf is also more likely to be invaded by weeds.

If possible, mow in the cool of the morning or evening. Mowing at midday may place additional stress on the turf. Also, make sure the mower blade is sharp. Dull blades tear and bruise the leaf tips.

Dormant lawns (those that have turned brown) should not be mowed. Pedestrian and mower traffic could damage the turf.

Runoff resolution

With the copious amounts of rainfall Eastern Iowa has received this spring, the Iowa Storm Water Education Program offers the following timely advice on lawns, runoff and water quality:

 

 

 

Can a Healthy Lawn Improve Water Quality?

 

 

   If you live in a newer neighborhood, chances are that during construction the valuable topsoil was removed from the site (and may even have been sold) and what remains is heavy clay subsoil.

    Heavy equipment was driven across this soil causing compaction. Then, once construction was completed and lawn preparation began, the compacted soil was lightly scraped, a thin layer of topsoil added, and sod applied over the top of that. In most cases, the lawn now functions similar to placing sod on top of a concrete block!

    The soil is so heavily compacted that the roots can’t penetrate to obtain the necessary nutrients from subsurface soils. This results in having to water frequently and over apply lawn chemicals.

     Rainfall that runs off compacted lawns, driveways, parking lots, rooftops, and streets flows into the storm drains. It is not directed to a wastewater treatment plant, but simply discharged, untreated, directly into local streams and lakes. The major concern with this is all the excess fertilizer, pesticides, motor vehicle fluids and sediment that accumulates on compacted lawns, driveways, parking lots and streets. These pollutants, carried along with the rainfall runoff, contaminate and severely pollute and impair our local waterways.

     What can you do to change this situation? There are a number of key things you can do with your own property. The starting point is to soak up as much of the rainfall on your property as you can, so that it doesn’t flow into the street. If your lawn is of the compacted type described above, chances are, it is not helping to reduce the runoff.

     Here are a few suggestions:

• Restore the health of your lawn by aerating and then apply a thin (1/4-1/2”) layer

of compost and seed.

• Use fertilizers containing zero phosphorus (the middle number on the fertilizer

bag indicates the quantity of phosphorus). Sweep up any fertilizer that is spread

onto sidewalks, driveways or streets and spread it back on the lawn.

• Use native landscaping and native turf in your yard.

 

     We all need to protect and improve the water quality in our streams and lakes. Please think about doing your part!

2008 Lawn and Garden Show

This event listing is from Master Gardener Becki Lynch. 

 I don’t know about you, but my “cabin fever” hit a peak this week!  As a gardener, these are the days that seem the longest – while I wait for a day close to 30  degrees so I can go out and bask in the heat! I’ve devoured all the catalogs; have all kinds of plans for spring; can’t wait to start cleaning up the beds – and I’m stuck indoors – AHHHH 

That’s why I look forward to the WMT Lawn and Garden Show every year. This year the show will be Friday, March 7,  3 – 8 p.m.;  Saturday, March 8,  9 a.m. – 5 p.m;  Sunday, March 9,  10 a.m. – 3 p.m. at Hawkeye Downs on Sixth Street SW in Cedar Rapids. Entrance Fee:  $5 (Look for coupon in the Gazette.)

 I am always eager to go and see all the booths.  Vendors from all types of garden equipment, garden art, landscaping needs and lawn care fill Hawkeye Downs.  I like to pretend for at least a little while that I’ll go home and go right out into the garden as I pick up new garden items. I also like the on-going door prize drawing.  I never seem to win, but there’s always a chance!  And, of course, I particularly like the Master Gardener’s booth, where you can ask any question you have on plants, gardens and those pesky garden pests. But my favorite time at the show is when I sit down and enjoy learning about a new garden topic.  Presentations are scheduled throughout the day, and the schedule is available in the Gazette prior to the show.   There are always one or two topics that I want to learn more about, and since the classes are included in the admission, the price is right! 

This year the Iowa State University Extension Linn County Master Gardeners will be offering four presentations throughout the event.  The topics are:

 

Kitchen Gardens – Friday, March 7, 5:30 p.m.

Landscaping with Ornamental Grasses – Sat. March 8, 12:30 p.m.

Garden with Children – Saturday, March 8, 2:30 p.m.

Old Gardener’s Tales – Sunday, March 9, 11:30 a.m.

 Such a nice variety!  Stop back next week and I’ll give you an overview of what they are and the topics they will cover – Becki
