Watch My Food Grow ~ A South Florida Raised Vegetable Garden

Florida Backyard Raised Vegetable Garden

The Conqueror Worm

… not the horror movie, but still horrible!

I picked the first acorn squash from my garden. I dropped it on the floor and when I picked it up, I was greeted by an unwanted guest crawling from a small hole in the squash. The drop must have dislodged it from its burrow.

Pickleworm

The folks at the Mounts Botanical Garden help desk identified it as a pickleworm. The University of Florida Institute of Food and Agricultural Sciences can tell you more than you ever wanted to know about pickleworms. The bottom line is that they are bad news for south Florida gardeners. Because they are very difficult to detect, the recommended treatment is to prevent infestations with applications of insecticides. In other words, get them before they get you. That is hard to accept if you prefer organic gardening.

The only place that pickleworms winter over is south Florida which means they attack early. They prefer to munch on the blossoms, but will go after the fruit, too. They damage summer and winter squash, cucumbers, cantaloupes, and sometimes pumpkins. In states farther north, damage doesn’t occur until August and September.

And you thought that was bad…

I inspect my garden daily and pick tomatoes, green beans and okra nearly every day. A couple of days ago, I was making my usual inspection and found a defoliated tomato plant where a healthy green plant had been the day before.

Yikes!  Tomato Hornworm

I don’t know how a caterpillar this big could have hidden for as long as it took to get this big, but I never saw this one until it was buried head-deep in a tomato.

The Mounts help desk people viewed this one in a plastic bag.  I couldn’t stand to touch it. I think I squealed a little when the limb was cut and the tomato full of  hornworm fell into the bag.  A picture would never have been enough. This hornworm was  a 4-inch long, as big around as my finger beast… beautiful to look at, but it pegged my e-e-e-ew meter.

The Mounts Botanical Garden help desk people were impressed enough to put it in a cage so that it could finish its metamorphosis unsquashed. The hornworm is the the larval stage of the hawk or sphinx moth. They are also know as hummingbird moths. About.com has an organic gardening section that has lots of  information on the tomato hornworm.

Peppers and Phytophthora Root Rot

May 17th, 2012 by Lila Steinhoff
Respond

In early March, my newly planted peppers began wilting overnight. After doing some research, it sounded like they were suffering from too much water. The plants were relatively young, and the rain in south Florida would not let up. My solution was to construct a box with much better drainage. I replaced the peppers and tried again.

Now, two months later, I am faced with the same thing. These are mature plants with peppers half grown. The stems of my peppers began to turn brown and the leaves wilted overnight. There was nothing I could do but remove the dying plants.

Professional Help Needed

More research turned up another possibility… a fungus. At this point, I decided that I did not know enough about this. It was time to have a professional look at my issue..

I took the 8th wilted pepper plant (of the 12 peppers I planted) to the Mounts Botanical Garden for examination. Mounts has had a Master Gardener Program with a help desk since 1979. I have taken problems to them over the years. They are a great bunch of people… friendly, helpful and extremely knowledgeable.

After filling out a form with my contact information and a little about my garden and my problem, I left the plant. I was told my wilted plant would be shown to a professional the following day. Mounts help desk volunteer, Dr. Kenneth Pernezny, who worked in agriculture with vegetable growers in the Glades, took a look at my pepper plant and come up with a diagnosis. This morning I received a call from Ken at Mounts with the bad news.

Phytophthora Is Terminal and Untreatable

The first thing Ken said was that my garden is infected with the absolute worst thing a home gardener can run into. My peppers are infected with Phytophthora. It is a soil-borne, anaerobic fungus that is unrelenting and terminal. There is no treatment available to home gardeners.

About the only bright spot here is that it is nothing I did. Phytophthora is naturally occurring in the soil. The weather conditions in south Florida this past winter… the continual hard rains, during what is usually our dry season combined with warmer than usual temperatures… caused this fungus to flourish.

I was on the right track earlier in the season when I constructed another box with better drainage. Unfortunately, the weather did not let up, so the fix wasn’t enough to save the peppers.

Vegetables that Are Susceptible

I plant what I like to eat… tomatoes, squash, cantaloupe, peppers, okra, green beans, and herbs this season.  Unfortunately, most of what I planted is susceptible to this disease. Peppers and eggplant are at the top of a list that includes tomatoes, squashes, melons, and other vegetables. I was told that even green beans can be affected, although, mine seem to be okay for now.

Ken said that grass-type plants such as corn and rice are not affected by this disease. He recommended planting these types of vegetables for a couple of years as alternatives.

What to Do Now

The growing season where I live in south Florida is just about over. Previously, toward the end of June or beginning of July, I would pull up what was left in the boxes, turn the dirt and cover the soil with a sheet of black plastic. The sun and plastic combination ‘bakes’ the soil in the boxes for several months until I’m ready to plant again in October. After talking with Ken, I found that I will need a new ritual this year.

Sterilize and Start Over

Phytophthora does not go away on its own. The contaminated soil has to be removed, and my containers will have to be sterilized before they are refilled. There is no way to treat the contaminated soil.

I asked Ken about disposing of the infected soil. Obviously, there is no way I can cart away as much soil as I have in two 2 x 4 x 8-ft boxes and one 2 x 2 x 4-ft box. I asked him about spreading the soil in my yard.

Ken approved that as a good option because grasses are not affected by Phytophthora. Ken did not know about how the ornamentals in my yard would be affected as he is a vegetable guy, but I have enough yard to spread the contaminated soil away from other plants. I have fruit trees and flowers all over my yard.

Sterilization Process

Once all the soil and weed barrier cloth are removed, the containers will have to be sterilized before new soil is added. The recommendation is to wash the completely empty boxes with a bleach solution. I plan to do so, as soon as the growing season is over and the remaining plants are finished producing in mid June or early July.

Start Up Next Season

I will remove the dirt from the containers, and I plan to leave them empty and exposed to the sun until October. Around October 15th,  I will repeat the bleach and water wash, then reline the boxes with new weed barrier cloth and fill them with new soil from my usual  nursery. I will ask a most important question at that time… “Has the soil you are selling been sterilized?” If not, I will be shopping around.

Green Beans… from Plant to Plate in 40 Minutes

May 13th, 2012 by Lila Steinhoff
Respond

For about a month, I have been picking green beans from the bushes I planted at the beginning of March. The bean plants are the most prolific of everything I planted. They are flowering all the time, and there are beans in all stages of growth on the bushes. This pretty much guarantees a continuous supply of green beans.

Pick, eat and share

I pick daily, but there aren’t always enough for a meal. When that is the case, I rinse and dry them and store them in the fridge in a plastic zipbag with a barely damp paper towel. This will keep them fresh for about a week if necessary. This allows me to keep picking until there are enough to cook or to give away.

Now, this is fresh!

I really can tell the difference in produce… in this case, green beans… picked and cooked right away and that bought from a grocer. Produce from the grocer is not necessarily bad, but it is different.

Just removing the stems is easier the fresher the beans are. There is no toughness at all. Sampling them raw is a treat. They are tender and crisp, and they snap, rather than bending.

The cooking time doesn’t seem to be as long, either. I saute green beans with a little bacon and onion, or I will toss them in the wok with olive oil and garlic. The taste is the clincher. So-o-o good!

40 minutes

Tonight, I picked green beans at 6:15, cleaned them, cooked them and had them ready to serve at 6:55. They went from the plant to my plate in 40 minutes. You can’t get much fresher than that. Bon appetit!
