Mail Order Sweet Potato Slips and EM-1

Last May I received a long-awaited package from a company headquartered in the East. The package contained two small bundles of very small-looking sweet potato slips.



Amazingly, the slips came out of a dented package out unharmed!



In the past, I had always produced sweet potato slips myself from sweet potatoes, and knowing that the daytime temperatures were already topping above 95 degrees Fahrenheit I thought it wise to start some of my plants in pots or vases indoors before planting them out in the garden. This was a type of experiment to see what method of planting would work best. The three different methods I tried were slip to garden, slip to pot to garden, and slip to vase to garden.



How my package arrived in the mail.

The package got a little dented. I'm grateful the slips made it.



General Sweet Potato Background: Sweet potatoes like a lot of light. By a lot of light I mean full sun in very hot, sunny places. Established plants do not require shade and are able to endure brutally hot environments. What sweet potatoes do have difficulty with is a lack of light. Any kind of environment in which plants are not receiving direct sun will make the plants dither or at least grow slowly.

The plants in the pots did not fare as well as those put directly in the garden

Though I put my indoor plants directly under windows, they had difficulty growing very well because they did not receive enough full sun. Most of the slips that I put in pots had difficulty establishing themselves indoors and did worse than those put out in the garden. Slips I put in vases did exhibit more root growth, which was helpful when it came to transplanting them in the garden. The constant sterile water supply was helpful, though a lack of direct sunlight was not. Slips that were put directly in the garden exhibited significant wilting over the first 10 days but did better after about 14 days. Filtered shading from a shade cloth helped minimize wilting until the plants could establish themselves well.

Recommendations: Based on my experience with mail order sweet potatoes I would recommend that the gardener either allow sweet potato slips to establish themselves in a vase that receives an abundance of direct sun or put the slips in the garden with filtered shade, such as shadecloth, until the plants become established. As filtered sun could decrease plant growth, and possibly yield, I would think that any shadecloth or filtered sun provides only a temporary benefit to the sweet potato slips as they are becoming established.

Shading Slips helps them become established without extreme wilting

One additional thought: Previously I had posted about a microbial product that is supposed to increase plant growth in the garden. The name of the Product is EM-1 and it is produced by Teraganix. The initial application of EM-1 seemed to have no impact on my garden. After two weeks of application no signs of increased growth or plant vigor were noticed. However, after 6 weeks of the initial application the sweet potato slips that were growing exhibited a dramatic increase in growth. The increase in plant growth was not imagined, but is very real. Though previous sweet potato growth did not move several feet past my garden, my current sweet potato vines have grown at least 10 feet past the confines of my garden. Neighbors are probably wondering why I have what looks like ivy growing out into my alley. My experience with EM-1 has taught me that it is an incredibly effective inoculant in growing sweet potatoes. I will be sure to continue to use this product for this purpose, in the future!

Cucumber Crazy and Saving Seeds

If you have been reading any of the other posts on this blog, you have probably determined that I like cucumbers. Apparently, my family does too. My kids are always happy to eat them, and if they don’t I am happy to do so also. Most of the time when I grow a new variety of cucumber (often a Carosello) my wife says something like, “These are the best cucumbers you have ever grown”. When I remind her that she has made that claim about a previous cucumber variety she will respond, “Well these are better than the last ones”.

Sometimes we enjoy our cucumbers a little too much

Saving cucumber seeds is also very important to me. No, I am not obsessive and no I am not hoarding seeds. Rather, I am preserving the cucumber varieties that are worth keeping, but are not being preserved because they are better suited for the home gardener than for long-distance shipping to grocery stores. Saving seeds is an important skill that is worth both learning and teaching to others.

Fruit on left is ready for seed saving while the fruit on the right is not

With patience most gardeners can learn how to produce high quality seed from their cucumber vines. With the Carosello, three of the factors in determining when the fruit is fully ripe and the seed is ready to extract include watching for a change in the color of the fruit, smelling the aroma of the fruit and gently shaking the fruit while listening for the slushy sound generated by the inner contents.



By gently shaking the fruit you may hear a slushy sound - be careful when cutting it open!

While I have much to learn about cucumbers, I continue to be fascinated by the growth, color, shape and beauty that are exhibited by each cucumber variety. 

The Carosello Massafrese

For those of you who are not familiar with what a Carosello is, Carosellos are cucumbers that are are a melon botanically and a cucumber agriculturally. This means that they grow like a melon but taste and are eaten like cucumbers - only better! The plant and fruit grows relatively quickly and they are really enjoyable to grow.

The Carosello Massafrese or Splotched Massafra

After trying out the regular round or “Tondo” Carosello Massafra I decided to try growing the Tondo Massafrese. The fruit of the Tondo Massafrese is just like the regular Massafrahttps://cucumbershop.com/product/carosello_tondo_massafra/ in shape and taste, except that it has light green splotches on dark skin (or in some cases dark green splotches on light skin). The taste is sweet and savory, yet slightly crunchy.



These Carosello were very fun to grow!

The Carosello Massafrese sets its fruit a distance from the main stem, while the darker Massafra variety sets its fruit closer to the main stem. Though having the fruit set closer to the main stem may be advantageous for some while others may prefer fruit setting farther down the plant.

Carosello Grow quickly

Early fruiting plants can sometimes give all their energy to the first fruits and end up with small fruits or dying early because their fruit growth outpaced their leaf growth. As a result, fruiting plants often produce fruit with large, vigorous seed. Another benefit of plants that produce fruit later on the vine is that the fruit is easier to trellis and keep from slugs or other pests that may be able to eat fruit left on the ground. The Carosello Massafrese is a good cucumber to trellis as my large fruit neither broke the vine or damaged the plant in any way.

I would highly encourage anyone who enjoys cucumbers to try growing the Carosello or other cucumber-melon varieties. They are bitter-free, easy to digest and delicious.

Carosello are fun to grow and tasty

This variety is now available at Cucumbershop.com.

Carosello Tondo Barese Trial

In between growing two other varieties of Carosello this last summer I decided to grow out a few seeds of another variety called Carosello Tondo Barese. Tondo refers to the fruit being round. There is definitely a correlation between cucumber growth and the amount of organic material in the soil, because the plants I planted in more fertile soil grew much faster than those without the more fertile soil.

Based on growing so few plants of this variety I didn’t get as much of a chance to taste this variety as much as observe it. Over time I have noticed that some Carosello varieties tend to fruit closer to the stem (which I believe is better for short-season gardens) while other varieties tend to fruit farther from the stem. The Carosello Tondo Barese definitely set fruit closer to the stem, which is something very helpful to know when growing this variety in the future. Though an early set of fruit can be adventitious, I believe that there are equal benefits to how the fruit sets, no matter what climate you live in.

Of Mediterranean Mantises and Mesquites

After a post about Mexican Bean Beetles I would like to focus attention on a more friendly insect. The Mediterranean mantis.

Based on how much the Mediterranean mantid blends in with the native mesquite trees it is no wonder that they have come to dominate much of the local insect population.

Often, people encounter this insect is when a male is attracted to a porch light and, while there, decides to dine on other insects that are attracted to the light.

Though mantises are all over Arizona, it can be difficult to spot them.
