I came across this horn worm on our grapes this morning. There were over 2 dozen white objects attached to its body.
It had been parasitized by another insect, most likely some species of wasp.
These types of wasps reproduce by depositing their eggs with their stinger into a host insect. In this case the unsuspecting insect is a horn worm.
The eggs soon hatch inside the caterpillar’s body. The newly released wasp larvae then begin to feed on the “innards” of the host insect while it’s still alive.
When the young wasp larvae have grown to sufficient size, they form”cocoons”, those white structures you see on the back of the caterpillar. The wasp larvae undergo a transformation inside the cocoons and emerge as fully developed wasps.
You can see by the size of the cocoons that these wasps are tiny compared to the paper wasps or hornets we normally see buzzing around the picnic table.
Let the balance of nature help you in your garden. When you see a caterpillar that looks like this, don’t squash or spray it, let the new wasps be “born”. They will soon be flying around looking for more caterpillars in your garden to parasitize.
By the way, this type of wasp does not sting or disturb people.
Anyone can grow fruits or vegetables in their own backyard. No special garden plot needed!
Edible plants can be tucked in a number of spots in an existing landscape. The only requirement is enough sun which in most cases is 6-8 hours of direct sun.
Any vegetable can be grown but some look better than others, so they can be put in more noticeable spots. Some plants that are being used for landscaping are swiss chard, parsley, everbearing strawberries, lettuce, kale, cabbages, peppers and many kinds of herbs.
Best results can be obtained if the soil is improved directly around the edible plant. Also, during dry spells, they will probably need supplemental water.
Blueberries and dwarf fruit trees such as apples, pears, peaches and plums are a good choice even though they need a few early season sprays.
Grapes on a fence or arbor can add quick privacy. There is even a hardy Kiwi vine for our hardiness zone.
Just think of walking out into your own yard in the summer and picking peaches off your own tree. Nothing tastes better!
bye for now,
I went out to the garden the other day to check out the beds that were planted last fall.
We had planted three beds, one bed of a leaf lettuce mix, one of spinach, and one bed of Bibb lettuce.
The Bibb lettuce had a heat coil buried to keep the soil warm. I fully expected that bed to be alive, and it was.
What surprised me was discovering that the other two beds were alive as well. They had nothing more than a plastic covering to protect them from the winter cold. It got down to at least -19F at this garden location.
It was the snow cover that we had this winter that made the difference! Under a foot of snow that was piled on top of the bed covers, the lettuce and spinach were still alive and waiting for a little warmer weather to start growing again.
You may want to think about making your own bed cover to get an early crop of lettuce this spring. A bed cover placed over a garden bed can start to warm the soil. You can start some lettuce plants inside then gradually let them get used to the cooler outside temperatures. Put them in a bright yet cool location (40’s to 50’s) for several days, then move them into your outdoor covered bed to get a real early crop of lettuce.
Keep in mind that your lettuce that you grow in that bed will be better than anything you will find in the store. Check the prices at “Whole Foods” or some other high quality produce department to get an idea of what you might have to pay for lettuce that only begins to approach the quality you will be harvesting!
Once your bed cover is made, you can use it next fall to extend the growing season.
…the garlic bulbs that is. Today we mulched our garlic beds. The raised beds we have for vegetable production measure about 5’x9′. Five pounds of garlic bulbs plant six of these beds exactly. We used wheat straw about 6′”-8″ deep to cover these six beds. Four moderately heavy bales did the trick. By the way, these bales of straw were of the most beautiful golden wheat color I have seen in a long time. In a way it was amost a shame to use them for mulch, but that’s what they’re there for. The bright color ensures that we don’t import a new batch of weed seeds from weed stalks that could have been baled up out in the field by the farmer along with the straw. Straw that has lots of different color stems in the bale more than likely are contaminated with weeds.
If you promise not to tell anyone, I”ll let you know the secret to growing super size and delicious garlic. So just let me know if you can “keep it under your hat”, by writing me a short note in the comment section that you like garlic.
Well, now that the garlic bulbs are all tucked in their beds for the winter, I think I’m going to have lunch and take a nap. Bob
