The Florida Weave

Tomato cages are often used by gardeners with small gardens in order to help them to keep the plants in a tidy contained area. However, tomato cages are often insufficient to support the weight of tomato vines that are laden with fruit. Many people have resorted to using thick wire mesh, posts, and wire ties to make sturdy supports for tomato plants. This works well, but can take a lot of time and money and requires storing the heavy gage mesh somewhere when it is not in use. Another option is to prune tomato vines and support them by tying them to walls or poles. This is not an option for me because the sun scalds fruit that is unprotected from the heat of Tucson's summers. What I prefer to use is a modified Florida weave method.

My modified Florida weave technique with my L. hirsusutum tomato plant

The original Florida weave method utilizes posts and twine to support tomatoes as they grow. The farmer or gardener comes back out to the field (or garden) to weave the twine slowly up the posts to support the vine as it grows. As shown in this illustration, the result is a wall of tomatoes supported by posts and twine.

Another tomato gardener, who is a member of the Seed Saver’s Exchange, thought up a modified Florida weave method using supports that can be adjusted from two large posts supported by metal line and stakes .
 
I twist the nylon line around poles between the two posts.

I chose to take elements of this gentleman’s method and of the original Florida weave method in order to support my tomato plants. The main thing for me is the method I use must be cheap and easy set up and take down. I use the two posts, with metal lines and stakes to support the ends of the line. Then I run a firmly taut UV stabilized nylon line around poles to make a line between the two posts, beginning from the ground to the top of the posts. The nylon line has a tension strength limit of 150 pounds. As I run the line from one side to another I twist them around posts at intervals of every several feet to keep up the tension on the line. I run my line on both sides of the tomato plants to keep them contained between the two walls of the nylon cord.

I support the posts with metal line staked to the ground.

The method worked well last year, as long as I pushed the new growth back behind the rectangular cage the plants were in. Last year I only grew semi-determinates and determinate tomatoes, so I didn’t have to worry about the plants growing up the full height of the trellised area. This year I am growing indeterminates, which may require some pruning to keep them from taking over my garden.

The Community Gardens of Tucson

While looking for an organization that could fulfill my gardening needs I came upon The Community Gardens of Tucson. Though I chose not to join their organization, I do enjoy talking with members of their organization and have come to appreciate much of what they do for all Tucson Gardeners.

The role of the Community Gardens of Tucson (CGT) is to establish and maintain community gardens and provide education to help Tucson residents grow food in garden communities within their neighborhood. In this endeavor, the organization has done a great job. In most every community throughout Tucson, one can find plots established by the CGT for local gardeners who are willing to pay the membership fees.

So what do gardeners get for their fees? They receive an irrigated lowered garden plot. As one speaker from CGT said at a Tucson Organic Gardeners meeting, they remove the native soil and put in a mixture of high quality soil that includes finished compost. Along with west side or partial shade, the plots established by the Community Gardens of Tucson are a very good example of what gardeners should do in a very hot climate. The pictures for this post were taken at only one garden – the New Spirit Garden near Old Spanish Trail and Camino Seco in Tucson.

The organization’s founder, George Brookbank, has written several books about gardening here in Tucson and has a fun little blog where he offers some advice and discusses seasonal gardening conditions.

Starting Sweet Potatoes


Supplies to Start growing Sweet Potatoes Indoors
Unless you are dealing with the Okinawan purple sweet potato, most sweet potatoes are pretty easy to start. One very good step to starting sweet potatoes is to find a potato variety that grows in your area. Georgia Jet seems to be one of the most popular varieties as it can be grown throughout most of the United States.

I prefer to find a Farmer’s market or a local farmer who is able to provide me with potatoes from my climate. I find sweet potatoes do very well here in the southwest, though regular potatoes do not.

I purchased my “seed sweet potato” from a local Whole Foods market in a section where they stated that it was grown locally and they produced a good number of potatoes. I am assuming the variety is Georgia Jet, though I can’t be certain. Previous to growing out the local variety I grew out two varieties I had bought from the grocery store that were from another state. The out-of-state potaoto grew large but produced very few potatoes.

 To start sweet potatoes, you will need a location to keep the seed potatoes very warm (80-90 degrees F). I use a reptile heat mat with a rhetrostat to keep the temperature consistent. You can choose to sprout them suspended in a jar with toothpicks or you can choose to start them in some kind of pit filled with sand or some other substrate. The important thing is lots of moisture and warmth. I prefer to start mine inside to grow out small sweet potato plants or “slips” from the potato.

Beginning Root Formation on Sweet Potato

Why not just plant the whole potato in the ground? There is always a chance that the potatoes might rot underground, causing disease in the soil and which can be spread to your new sweet potato crop. In the sweet potato industry they will grow out new plants out of the potato in growing beds and harvest the young plants (called slips) from the soil when they grow large enough to continue growing without the mother tuber. These slips are then transported to the fields where they are transplanted and grow into the sweet potato crop. There is another method (that I outline in another post) to starting sweet potatoes in the garden that allows them to get started quickly as long as you are using known healthy sweet potato stock.

Sweet Potato Slip (plant) forming on mother potato.

Growing out Sweet Potato Slips: For my jar and toothpick method I cut the sweet potato in half and suspend 1/2 to 2/3 of the potato below the rim of the jar using toothpicks. Then I fill up the jar with water, put it in a warm place and make sure to change the water often. It can take 1-2 months to get sweet potato slips started so make sure to plan that much time in advance.

Care: Compared to many other vegetable varieties sweet potatoes are relatively maintenance-free and do not require an excessive amount of fertilizer or pest control to grow strong healthy plants. They do perform better in areas where the dirt has at least had the large rocks sifted out. Once they have established themselves I just keep them well watered and occasionally make sure no large creature is chewing on the vines. Some bugs will chew at the vines but usually the vines grow faster than the bugs can reproduce.

Harvest: I usually harvest right after the first slight frost. Sweet potatoes tend to die at the slightest frost, which around here can often be in November or December. Though some use pitch forks to harvest their sweet potatoes, I choose to harvest by hand, following the roots from one tuber to another. Once I harvest my sweet potatoes I keep them moist and warm in my water heater closet to cure them. Curing the sweet potatoes allows them to store longer, which is essential I would like to plant sweet potato vines out again next summer.

Magic Garden Nursery

A year or two ago I was having a difficult time and wanted to relax taking a look at what vegetable varieties were available from a local nursery (who shall remain un-named). While browsing the seed rack with another customer I told him about a few vegetable varieties that had grown well for me. Upon hearing the conversation between the other customer and I, the manager/owner of the nursery angrily told me to leave and added that I was never welcome to come back. Having purchased garden supplies from the nursery before, I left confused and upset at how I was treated.

Within a few days I came to Magic Garden Nursery to find friendly people, who care about me just as much as they care about the plants they grow.

I love coming here.
The above true story is just one of many reasons why I patronize the Magic Garden Nursery. A few other reasons include some very knowledgeable staff, an inviting laid-back atmosphere and the fact that they carry a great selection of heirloom (and a few award-winning hybrid) vegetable plants that do well in my climate.

Some Squash
Though I remain pretty self-sufficient most of the time, occasionally I choose to splurge. Rather than growing from seed once or twice I year I buy a Celebrity Tomato plant, or a hard-to-find heirloom that is already half grown or some soil ammendments. I also enjoy browsing seed racks to find vegetable varieties that I have heard might do well in my climate.

The problem with Celebrity Tomato Plants in a small cage is large tomatoes

Tony Sarah, the manager, has teased me about how little I buy compared to how much I browse, but I don’t mind – because as long as they continue being kind to me I’ll keep spending my money there.

Magic Garden Nursery has a pretty fun website that reflects their approach to gardening  – that it should be fun and enjoyable. If you live in Tucson and have had a difficult time at any another nursery I highly advise you come down to Magic Garden.

Improving Chances of Gardening Success


Twisted Curly new Tomato Growth
Imagine that a new gardener in Tucson, AZ (USDA Zone 9a) buys some generic tomato seeds and plants all of them in mid-May. What happens? The few that grow quickly die because the odds of success are over 1,000 to 1. Will planting more seeds increase the gardener’s chances of success? Probably not much.

What will increase the gardener’s chances for success while decreasing his chance of failure is knowing and applying concepts about planting dates, climate conditions, soil conditions, what conditions help tomatoes grow best.

I recently had to pull out almost half of my tomato plants because of disease. I am hoping that, over the last few years I have improved my chances of success with growing tomatoes from odds of 1,000 to 1 to closer to 30 to 1. Meaning that I fail 30 times for every 1 time I succeed. Good thing most tomato seed packets contain over 30 seeds. My success rate is much higher with plants that grow well in Tucson’s climate.

Each time a gardener fails at something a more insightful learning is exposed.

Here are a few things I have learned through study or plain experience about a garden’s temperature and disease that have helped me.

Temperature:

- Radiant heat in winter is good. Radiant heat in the summer is bad. Walls, buildings, some trees, and plastic bottles can provide radiant heat.

- South facing slopes, walls or buildings in winter is optimal. East facing slopes or west side shade in the summer is optimal.

- Troughs or furrows in the garden keep plants cooler and wet in the summer while hills keep plants warmer and drier in the winter.

Disease:

More diseased tomato plants
 - Once a disease attacks, remove the whole plant immediately (roots & all). This will decrease the spread of disease and hasten the time when that vegetable variety may be grown there again.

- Composting diseased plant material spreads the disease. Don’t do it! Burn it or throw it away.

-Once disease hits do not plant the same plant in that soil for at least a year (or more depending upon extent of disease). Options to overcome this is to move next year’s planting location for that crop, growing other vegetable crops there, or using new soil that has never been used for growing that crop before.

- If you plant a disease-resistant variety in a diseased bed, it will most likely get the disease.
Disease can mangle a tomato plant

- Growing legumes next to other plants or before other plants helps to increase beneficial bacteria in the soil and may decrease the chances of disease (as a preventative measure). My best success with this has been to start the legumes a few weeks before introducing my main crop. As long as they are not competing for light, experience has taught me that growing a crop of beans near other plants has only benefited the nearby plant.

- Learn about each vegetable variety you plan to grow. Know its needs, its strengths, it weaknesses, and how to combat potential problems.

- It is good to occasionally take a break from higher maintenance crops so that you can appreciate your other plants.

-Do not treat disease as a bad thing. Learning about plant disease enables the gardener to adjust his gardening practices and increase his chances of future success.

My chances of seeing my tomatoes live may be as good as 1 in 20
 
To anyone who lives in a climate where the odds are stacked against you – I feel for you. As you find out all you can about growing things you want within your climate you will be increasing your chances of success. Everyone fails at sometime. It is only those who learn from their failures who can cut their losses and improve their opportunity for success. The more I learn about my garden, the better I increase my chances of getting something right. As Thomas Edison once said, “I have not failed. I’ve just found 10,000 ways that don’t work.”
