Iowa Lemons!

Lemons can be a lot of fun to grow in Iowa!  Wait, what!?  That can't be right...

Unless you live in a tropical or semitropical climate the idea of growing your own lemon tree might seem impossible.  It may not be possible to grow a citrus in the ground here (without some serious effort*) but we can easily grow them, in pots!

These wonderful trees can be a unique addition to any home.  By growing a small lemon tree in a container, you'll be able to get homegrown lemons with limited space, even in the Midwest.  In addition to lemons, the flowers are beautiful and smell amazing! 

Lemon trees actually have pretty good cold and heat tolerance, but our winters get cold, and they need to come indoors.  Growing lemon trees in pots allows them to be mobile.  Having a "mobile home" won't mean they can head south for the winter, but it does allow them to "migrate" to the inside. 

In summer you can put them on your patio, deck or an open area by your vegetable garden.  An apartment balcony can be great too, especially for those who have limited access to other kinds of gardening.  Besides a few citrus trees, I also keep lemongrass, rosemary and bay laurel on our deck.

Almost like a container food forest!

As the weather starts to cool off simply bring them indoors for the winter.  When the temperature gets down below 50°F I'll make plans to bring them in, a frost can be deadly to a potted citrus tree.  Check for aphids, spider mites and scale so you don't bring those in with your tree.  A spray with insecticidal soap usually does the trick.  If your citrus tree drops some or many of their leaves when moved indoors at the end of the growing season, don't worry!  This is a natural response as the tree adjusts to different light levels.

When the late winter months start to seem extra, extra-long you can enjoy the bright, citrus fragrance and think of warmer days soon to come.  With proper care, growing a lemon tree in a pot is easy enough that you can do so anywhere.  

Even in Iowa...

Snack-able Rain Garden in Clive

Earlier this year Clive rolled out its new stormwater assistance program 

City of Clive's 

NEWLY UPDATED 

Stormwater Assistance Program

We shared their website on our social media, and soon after, we were contacted about installing a rain garden close to our office.  The first one using their new program.

The homeowner wanted to help by reducing her runoff and is making steps to become more environmentally responsible with her property - less spraying and more habitat.  However, she isn't fond of the wild, "prairie look" and hoped for something "tidy" looking.

Keeping this in mind, much of the basin floor was covered with low growing sedges for a clean palette.  As the eye travels towards the back and berm, we added a bit more diversity to try to maximize time with blooming plants, balancing that by keeping the number of different species lower.

And, as much as possible she wanted to include lots of edible and food producing plants.  We mentioned this fun project earlier!

We do have a fair amount of smaller native plants with edible fruit such as serviceberry and gooseberries, so we used two of each!  Although not in this project elderberry, paw paw and hazelnuts would be good native options too.  We also included strawberries, asparagus and some herbs.

We were sold out of strawberries, thanks to Iowa Backyard Farmer for these!

A rain barrel was also on the project wish list, too.  She chose a barrel that she found online, which matched the house well, but was a little different for us to install.

The overflow was directed down the front and the online reviews didn't make me feel confident we could drill into the side without damaging it.

We removed the existing downspout extension, to make mowing easier, and buried a drain tile in its place with a popup.

Before installing the stand and stabilizing rock, I ended up putting in a perforated tile under the overflow.  This was connected to the downspout tile we buried.  

I used larger river rock there, to hide that pipe, and also allow the overflow water in where it was directed into to the downspout tile and popup.

While I worked on the rain barrel, the guys started burying the downspouts and excavating for the catchment basin and berm.

Once the basin was dug, the amended soil was added, and inlet/outlets were armored.  The plants were put in, watered well and mulched.

For the final reveal and walk through, her sister was visiting and invited along.  They shared some family stories, and both agreed that they "absolutely love it!"

Since the strawberries are everbearing, and were already growing well, they have produced enough for a treat every few days! 🍓🍓🍓

Secluded Woodland Oasis & Gardens

After their new addition was built, these Urbandale homeowners saw it as their chance to include some new outdoor elements they wanted instead of just repairing the construction damage.

Patio, bench wall, garden beds and stream behind

It included a patio with bench walls and a firepit, vegetable and herb gardens.  A dry stream directs stormwater runoff to a pair of rain gardens.

to access the existing woodland paths

In the production area, herb beds run along the access path at ground level and are just at the edge of the available sunshine.  The raised vegetable beds benefit from being a bit farther away from the house's shadow, and being elevated helps to get more sun on them too.  Trellises were also added for some vertical growing space.  

The block used on these beds is durable, looks great
and compliments the patio and bench walls!

The garden beds were going in near an existing Hackberry tree and I was concerned about tree roots invading and stealing water and nutrients from them.  

See how we addressed the Tree Root issue HERE!

A Rain Barrel catches rain for use in the gardens

The rain barrel overflows into the downspout drain that connects to the lower rain garden basin behind the raised beds.  Shade loving plants were predominantly used throughout the rain garden plantings - columbine, woodland phlox, sedges and wild geranium.  A few pockets got more sun, so we could try for some more color using part sun and native savannah plants - cardinal flower and bee balm.

Thanks to Beemer Landscaping on the hardscaping assist!

We also cut and removed lots of invasive honeysuckle filling several dump trailers worth.

Reusing saved materials was high on the list of customer desires.  The patio stone was selected to match pavers leftover from a previous landscaping project.  These existing pavers were incorporated into the access path to the side yard, gardens and rain barrel.

Leftover pavers and stone from a previous
project we used for edging and steppers

Several pallets of assorted limestone served as edging along the access path above, and a walking path expansion loop through the side yard along a new planting bed and retaining wall.

Dark trap rock contrasts well against pale limestone,
but it's dusty!

The construction access was cleared of wood chips last fall.  After the temporary driveway was used for a needed tree removal, it was dormant seeded this Winter with a customized woodland sedge and wildflower mix.  Timing was perfect with 4" of snow falling that night.

We love how it has turned out so far, and excited for fresh growth and blooms this season!

Tap Those Trees - with Video

Each year at the end of winter and beginning of spring, there are a few weeks of magic that happens.  Tree sap starts to flow, bringing life from the roots back into the branches. Farmers across the northern US and Canada collect sap from their maple trees as they have for over two hundred years.  

The sap is collected and usually taken to their "Sugar Shack." There, this barely sweet, clear sap is boiled down using time-honored methods passed down from generation to generation to produce the sweet, dark maple syrup we use on pancakes, waffles and more.

You can also take part in this historical tradition right in your own backyard (or a friendly neighbors)!

This week's forecast looks great!

Sugar maples are best, with typically higher sugar content in the sap, but I had a garden design customer tell me he got over 40 gallons from a large silver maple in his yard!  I think our tree is probably an Autumn Blaze hybrid maple from the looks of the fall foliage and how common they are in the suburbs.

2016 Home & Outdoor Living Show

You can also tap Birch, Black Walnut and I've even heard of Butternut trees for uniquely flavored syrup.

These Hook Spouts are especially designed to hold pails with holes smaller than ¾ inch. The hook slides on behind the washer.

• For use with sap pails. Hook to hang bucket & specially cut drip-edge
• High quality construction. Durable and reusable for year after year
• Use a 5/16" drill bit to drill a hole into your tree and simply hammer this tap into place
• Can be cleaned by boiling in water each season

This video from our backyard tree demonstrates a simple "how-to" tapping method for you-

From the Northern Midwest to New England and into Canada, the sap is boiled down into Maple Syrup.  This is often done in large pans over an open flame outside, as boiling sap into syrup produces a lot of steam.  And it takes a lot of fuel.  Sap is continuously added as the water is boiled off, carefully making sure it doesn't boil over or burn the pan.  It typically takes around 40 gallons of sap to make one gallon of syrup.

If you have access to enough trees and want to try making some syrup yourself, here is a great guide from the University of Maine Extension Service.

We just drink the sap since we don't have many trees and its high in minerals, other nutrients, enzymes, antioxidants, and more—an incredible, all-natural beverage with less than 2% sugar!

If you want to experience it in person the Indian Creek Nature Center near Cedar Rapids is having a Maple Syrup Festival on March 23 & 24 this year.

Parking Pad to Garden Transformation

These new homeowners had an idea for their backyard, and it didn't include the existing gravel parking lot.

They also had significant yard damage from a geothermal system, that was not repaired the way they had expected.

The goal was for a natural, relaxing space filled with as many edible and ecological benefiting elements as possible.

We began with three main goals- a garden, a patio and a fence.  Garden beds were high on the priority list for clean growing fresh produce!  A relaxing patio for their firepit, surrounded by a natural environment using some of their existing plants and lots of new natives.  A future fence was planned to separate the new space from alley noise and traffic.

 

Many edible plants were hoped for both in the garden area and even around the yard.  We put in as many perennial and edible plants as practical for this space.  Rhubarb, asparagus, berries and even an apple tree.

Initial site work involved removing the gravel and breaking up the compaction of years of traffic.  We left a circle of the existing pad for the base of the new paver patio.

 

A keyhole style bed maximizes growing space on a smaller overall footprint.  

Raised frame beds allowed us to bring in a fresh mix of clean soil to grow in.

We added compost to the remaining planting areas to add organic matter, build soil structure and workability, as well as encourage soil life.

With a limited space and south facing wall, this was a perfect space to espalier an apple tree.  The downspout from the garage allowed us to capture rainwater for use right by the garden.

Companion plants were included in this tree guild -

    Yarrow to attract beneficial insects

    Clover for nitrogen fixing action

    Chives to protect the trunk from rabbits

    Other herbs for their antimicrobial benefits

A decorative Japanese Maple was the focal point for the back corner with an Asian palette, a Serviceberry up front for a native edible shrub and multiple species of native woodland and savanna plants along the neighboring garage.  Bee Balm is great addition against the patio as it repels mosquitoes and feeds beneficial pollinators, and dwarf varieties soften the edge from lower to higher plantings.  Narrow evergreens will frame the future access gate and provide shades of green in the winter.

Great work on the patio from Ben's crew at Beemer Landscaping

We had just completed another project where a large amount of sod was removed.  So, after leveling the damage to the side yard we were able to upcycle it here instead of only reseeding.

The stepper path was re-laid through the damaged lawn area, using the existing pieces and we were able to match extras we needed.  The path was also extended from the back sidewalk to the patio area and gate.  

Finally, everything was mulched and finished.  A few weeks of garden care during their vacation, and then an additional Redbud tree for more afternoon shade.  It was all ready for the privacy fence install.

A little taste of Eden in the heart of our city.  If you like this project or our others, we'd love it if you shared it with your friends!

This visitor couldn't wait for us to be done :)
