Fall is for Trees!



As summer winds down and school starts back up for many, it may feel like the party is over... but with cooler temperatures comes a beautiful time of year, full of warm colors, falling leaves and favorite sporting events.

Fall is also a GREAT time to plant trees!  Planting in the Fall can set your new trees and shrubs up for long term success, with less stress than summer and beneficial root growth for a head start next season.

Cooler autumn temperatures help reduce transplant stress and moisture loss.  As long as the soil temperature is above 50°F the roots of the tree are still growing.  This extra time, typically into mid-November in Iowa, enables roots to get some extra growth before going fully dormant.

Soil Temperature & Garden Plants 

Autumn's arrival might even bring more rain than the hot and dry weather we've had lately and typical of late summer.  Combine this with the cooler temperatures and your trees might not use as much water as they would during the spring growth spurt and summer heat.  Even during the fall your newly planted tree will still require watering, however, especially to hydrate the subsoil well going into winter. 

"The best time to plant a tree was twenty years ago, and the next best time is now!"

One thing to consider is that these recommendations are for potted or container trees.  We don't plant dormant bare-root material in the fall in our climate.  They are hard to keep from drying out and winter will almost certainly kill a bare-root tree planted too late in fall in the North.  Early spring is a much better time to plant bare root trees!

When winter arrives your care activities can "chill out" for a few months, but...  

You'll want to keep young trees protected from deer and rabbits (more on that here)

Ask an Arborist: Why Should I Plant in the Fall? (youtube.com)

You might be wondering "How do I plant a tree well?"  Here is a quick overview of how we plant our trees-

Step 1 - Dig hole to a depth of 2" less than the rootball height and twice as wide.  You want the root crown just above the surrounding soil.

Step 2 - Remove the container and break up/cut any pot bound/circling roots, place in hole, and backfill about halfway.  Make sure tree is straight and plum.

Step 3 - Deeply water around the tree letting the water settle the soil. Finish backfilling and watering.

Step 4 - If needed tie up tree for stability.  Two T-posts at the North and South sides, driven outside of the excavated area, are usually enough.  Tie using wide straps with enough tension to allow flexing to strengthen trunks, but not so loose to tip or lean in strong winds.

Step 5 - Mulch in a ring 4'- 6' in diameter, 3-4” deep with hardwood mulch.  Leave several inches between the mulch and trunk to prevent fungal infection.  

Avoid the mulch volcano... instead go for a mulch donut!

Over the next few weeks and months observe and water as necessary until the tree is fully established. 

Water daily for 1-2 weeks; then 2-3 days for 3-12 weeks; then weekly until established

Apply 1-1.5 gallons per inch of caliper (trunk diameter) at each watering

If the ground does happen to thaw in winter, it would be a good idea to try and see if you can get some water to your young tree.  Winter's drying winds can evaporate moisture from the soil, especially if we don't have a protective blanket of snow.

A smaller tree will take nearly a full growing season to become fully established.  A 2" tree may require two years to become fully established on its own while a 3" tree may need three years. The larger the tree, the bigger the shock so continue to be diligent and observant even long after the initial planting and water accordingly.

"A society grows great when old men plant trees under whose shade they know they’ll never sit."

Easter Lake Rain Campaign Video

Here's a fun video we helped make with the Rain Campaign to showcase rain gardens as a Stormwater Best Management Practice.  Their videos help encourage homeowners to consider rain gardens and other best management practices to help with stormwater runoff mitigation and to help them with potential problems in their own yards - erosion, soggy areas, etc.

We had already been working with the homeowners in conjunction with the Easter Lake Watershed coordinator to help them with their yard issues and reduce the storm surge into the lake.  The following pictures show the flooding and poor drainage they were dealing with in their yard.  You can also see Easter Lake behind the trees and shrubs.


Their pipe was a short-term fix, and definitely not their favorite.


Watch the video here, with project photos following.

Mulching the fresh planting helps retain soil moisture and will feed the soil as it breaks down.  The basins are mulched lightly to prevent smothering of young plants when the basin fills and empties.

The basin captures and infiltrates the first 1 1/4" to 1 1/2" of any rain event.  90% of historical rains for our area are under this amount. If we get more rain than that, the excess will be slowed and filtered through the native plants, and slowly go over the armored overflow.

This picture is from the second year, and you can see the plant growth, adaptation and personal touches.  We designed the planting to be shade tolerant initially, yet take advantage of the future sunshine too - the park was planning restoration of the native savannah surrounding the lake.  Lots fewer, but quality tree species.

This year (year 3) we were doing another project nearby and were invited to come check it out.  After 2 years you can see continued adaptation and growth (although earlier in the season), and we happened to catch it filled with rain.

Stay tuned for more videos!

Back-to-Back Edible Rain Garden Installs

Earlier this season we had been joking that even though we were busy, we hadn't done a single rain garden installation yet.  We had done some revamping of a couple older ones, an edible landscape for a commercial project, several large native plantings and a homestead orchard.

Little did we know that we would do two back-to-back rain garden installs, that also wanted to include as many food producing plants as possible!

This first project in Clive was the first to use their newly retooled cost share program (link).


The other was in Des Moines, and after a little time to think it through, they decided to go for it!


More details on these projects are coming up, but I was excited to share the combination of stormwater, natives and edible plants and trees!


Sod ...but it's Prairie!

Earlier this year the Polk County Water Resources team asked us to help with a special project.  They were hoping to try a new prairie sod product they had learned about by webinar.  There was a small drainage easement near Ankeny that was a likely candidate for this project, and the neighboring homeowners had been fighting weeds and water issues for several years while trying to maintain the space.

Messy drainage easement from the outlet

Many suburban developments have a drainage easement that runs along the back property edges.  A lot of homeowners can have issues with poor turf grass quality and drainage issues in these areas, especially if the grading is variable at installation or settling over time.  These issues usually get worse as you get closer to the end.

With steady Spring rains delaying cutting, a communication mix-up and surprise shipping date, the schedule was in a bit of a kerfuffle, but we rearranged our plate and things turned out ok.  Pfew!


The existing sod was cut and removed, using it to patch in some rougher spots along the neighboring lot.  Looking at these pictures is a reminder of how much turfgrass there was.  
Those rolls were heavy too!


Pallets of the new sod arrive at the job site.  The plants were well rooted into the mat material.  Even though it seemed shallow, there were many species (guessing the deeper-rooted ones) were seedlings mixed in with the taller grasses, sedges and quick growing black-eyed susans.  Our little dump trailer has moved a lot of material over the years!

Native Prairie Sod, delivered and untarped

The Prairie Sod was installed and pinned, with extra pins and rock armor near the storm drain outlet.  We also rearranged the boulders to make mowing easier for the homeowner around the outlet.

And why would it not rain during the installation?  Rain days hit us hard when our projects are typically right in "the line of fire", or flooding in our case.

Eventually it dried out enough for work to continue!  Time to rearrange the boulders...

This, along with the sod laid at the Public Works facility, will be a good test case for the water resource team to assess feasibility of using native sod in stormwater projects.  It provides instant coverage, many good-sized plants from day one, a few early bloomers in flower, with others soon to follow.  It has lots of water flow down and across the site, typical clay soil and full sun.

I could see us using this for similar products in the future as it seems like a great solution for large projects, new construction and commercial parking or neighborhood detention basins.  I also imagine, at least on some of our projects, we might design an intentional planting of selected natives as a border and to lead the eye into the "wilder" look of prairie sod like this.

Ticks! ...and Invasive Barberry

 We design and install edible landscapes, we are NOT edible landscapers...

...someone needs to inform the ticks and mosquitoes!


A recent article I read mentioned that some invasive species of plants can increase populations of ticks!  It turns out, the dense, thorny Japanese Barberry shrub is actually great habitat for ticks.

How an invasive plant is helping ticks survive

“Barberry thickets actually make a pretty good habitat, not just for ticks but for some of their host species,” said Susan Elias, a research associate at the Lyme and Vector-Borne Disease Laboratory at the Maine Medical Center Research Institute in Scarborough. “You’re creating a perfect storm, when you have these non-native species coming into the landscape.”

One of our last job sites had a TON of ticks (quite a few have this year), and we removed several barberry shrubs in addition to the retaining walls and prairie bed install.  I don't know that the ticks were living here with the abundance of other habitat nearby, but it will keep these bushes from reseeding (with help from birds) throughout their acreage and other natural spaces. 

Invasive Barberry, ouch!

Invasive species can cause lots of issues in our natural areas.  

Before planting anything new, check to see if it is invasive (not to be confused with an aggressive native) and if you need assistance with invasive species removal we can help!
