Smart Gardening

Let's combat those horticultural myths with science 

This meme with a reminder to share
about male and female pepper fruits based on
 the number of lobes is total baloney!

The Internet has been a fantastic tool for sharing all of human knowledge. Social media, powered via the Internet, has made it easier to reconnect with long-lost friends and relatives and to share photos and memes with the world. It also serves as a market place, with online shopping.

But all this mostly unfiltered access to eye balls has made it ripe for spreading misleading information and blatant misinformation. Plus, this unfiltered marketplace allows for the selling of ineffective or bogus products with no chance for returns.

But, our topic is gardening and landscaping, so let's look at a few examples of bad information so widely shared that those myths have become accepted as fact.

Reworking a downspout after drainpipe clog

In 2005, I lined the gully from the outflow
 pipe with rocks to stop the erosion. 

Handling stormwater

When we moved into tour house in 2004, the downspout off our back porch was attached to a flexible 20-foot long drainpipe that had been buried. The stormwater was released onto a slope in the woods. This house was about 2 years old when we moved in and during that time, the stormwater had caused significant erosion in the woods.

Since this wooded area is a shallow ravine which serves to drain our front pond back into the lake. Eroded soil washing into this ravine could be carried into the lake during heavy storms, so I wanted to reduce the erosion.

My solution was to fill in the large hole right under the pipe and to line the gully with rocks. I wrote about this project in my first rain garden article: Rain lilies for my rain gardens.

Sequester this carbon! Don't throw it away.

Sequester this carbon! Don't throw it away.

Carbon sequestration is tremendously important because keeping the CO2 levels low in the atmosphere will help keep the earth cooler. It’s the most abundant greenhouse gas.

As I found in doing the research for the Soil section in "Climate-Wise Landscaping," soil sequesters four times more carbon globally than all the terrestrial plants added together, including rainforests. It varies by region and soil type with the peat bogs doing much of the heavy lifting.

Speaking up for our only planet

Show & tell! I bought this nandina to make
the point that Florida is spending millions
to remove invasive plants, but many of them
 are still for sale, which makes the problem
even worse. I asked them to make it illegal
to sell known invasives. 

The 2019 Clay County Delegation meeting was October 10 at 2:30pm

Each fall in Florida, there are state delegation meetings in every county where people can address their Florida legislature representatives. I'd called my senator's office more than a month earlier to put myself on the agenda. You have only three minutes to make your point, so I'd planned out my topics and had put together a handout to give to the legislators with my points and links for more information. (See my handout below.) This is necessary, because people might be distracted with side conversations that may come up during the hearing. I print my handouts on green paper.

Enrich soil for crops by composting in-place

Time to remove more lawn and replace it
with larger edible garden beds.

Several people have requested more information about how I compost in place, so this post includes extreme details.

More lawn removal!

This adventure in gardening began with more lawn removal. In the fall of 2016, I'd created a new bed in front of the rain barrels. It was only about 5' x 4'. Here are the details of "Creating a New Bed."  

April 29, 2019

Over this past cool-weather season I'd grown broccoli and curly parsley in the new bed, which had done fairly well. I keep picking the broccoli florets after the initial big curd harvest, so the broccoli season lasts for a long time, but now they were at the end of their cycle. The parsley would last for a while longer.

An update: red bay trees that died back from laurel wilt disease in 2008.

Three months before the red bay tree by the
pond turned brown, seemingly overnight,
two pileated woodpeckers gave warning
that bugs were infesting the tree.

Back in 2008, we were shocked when all the red bay trees (Persea borbonia) in our yard suddenly turned totally brown. One day they looked fine, the next day their leaves were all dead. After doing some research, I found that the cause for this was the laurel wilt disease, which was carried by the redbay ambrosia beetle, a tiny insect that entered this country in pallet wood from Asia in Savannah, Georgia in 2004. The beetle carries a fungus that blocks the xylem cells so the water stops flowing through the trees. This is why the symptoms are so sudden, because without the flow of water, the tree cannot function. The fungal disease is known as the laurel wilt disease. Other members of the Laurel family (Lauraeae) that are susceptible to this disease include both natives such as sassafras and spicebush, and non-natives such as avocado and camphortree. Here is a link to the article I wrote back then: Red Bay Trees are Dying.

Bucket gardening for your edibles

Wes and his self-watering bucket garden

Two years ago, I was in Maryland and when I visited friends Wes and Tammy for a gathering at their house, I was intrigued with the self-watering bucket garden that Wes had set up.

Advantages to a self-watering bucket garden

This self-watering bucket garden has a number of important advantages;
- Protects crops from damage by animals such as rabbits, chickens, ground hogs, armadillos, and pets.
- Because of the water storage in the lower bucket, your soil stays evenly moist for a week or so depending on heat and humidity before you need to refill the bottom bucket.
- Reduces water usage because all the water is right in the bucket, it does not drain away and no water is lost due to irrigation onto non-growing areas.
- Eliminates weeds and soil-based pests, such as root knot nematodes, cutworms, slugs, and others, if you use purchased or sterilized soil.
- No bending over once everything is set up for the season. Everthing is waist high.
- No plowing or other soil disturbance, so your soil can continue to sequester carbon.

End of March Blues

I was struck by all the blue flowers we have in our landscape at the end of March. Yes, there are some reds, pinks, and yellows, but the predominant color right now seems to lean to the blues.

(Note: For reference, I've included links to the species profiles on Atlas of Florida's Plants website where you can see the native ranges, other photos, and more.

Savanna iris

Savanna Iris

When I bought my starts for this Savanna Iris (Iris savannarum), I thought it was Dixie iris (I. hexagona). It was several years ago, but I think that's how it was labeled, but it turns out that it's not because it's not evergreen and the seed pods are not hexagonal enough. Also the Dixie iris is native to just a few counties in the Big Bend area, so it's preferable to have those that are native to my county.

It's done very well on a mound I built at the northern end of our front pond. (Click the link for more information on our pond.)

Transpiration: Forests' most important service

Through transpiration trees extract huge amounts of water from the soil
and spew it into the atmosphere.

Three Major Cycles in Forests

For a better understanding of the overall value of trees, we'll look at the three major cycles in forests. There are many other processes that also take place, but these three will provide a big-picture look at what's going on in forests, which can then be downsized to fit into our local activities in our yards and in our communities.
1) The Water Cycle:  Water moves through trees, evaporates into the air, forms clouds, rains or snows, both locally and globally. Water from the precipitation is soaked up by trees.
2) The Carbon Cycle:  Carbon absorbed during photosynthesis and is released during respiration, fire & decomposition.
3) The Oxygen Cycle:  O2 is produced through photosynthesis and absorbed through respiration.

Review: "Garden Revolution: How our landscapes can be a source of environmental change" By Larry Weaner and Thomas Christopher.

Cover Garden Revolution by Weaner & Christopher.

On my 2018 book tour presentations, I talked about some of the ideas on better meadow management that I learned from Larry Weaner in his presentation at the 2017 FNPS conference and from his Garden Revolution book. So here is my review of it for Florida gardeners:

Book Review:
"Garden Revolution: How our landscapes can be a source of environmental change"

By Larry Weaner and Thomas Christopher. Published by Timber Press in 2016.
(This review was written for & published in the Palmetto, the journal of The Florida Native Plant Society in 2017.)

I attended Larry Weaner's presentation at the 2017 Florida Native Plant Society conference and was so taken with his philosophy that I bought this beautiful book. While Thomas Christopher is listed as the coauthor, he explains that even though the point of view is Larry's, that they both worked on the organization and the actual writing of the book. For this review, I continue their scheme and refer to the ideas as if they were Weaner's alone.
