Late Summer Garden Experiences


Late summer gardens, unfortunately, require sustained work.  If you didn't plant those second crops for   fall harvests, don't be discouraged by what now seems like just extra effort for clearly diminishing returns.  Gardeners, like old men planting trees, must be  optimistic in  believing that any work done now is really for the next growing season...

Brussels sprouts  Update

Three weeks ago I mentioned that my Brussels sprouts were not forming buds but exhibited extensive leaf growth due to the warm growing conditions.  I removed the top leaders; and presto, within two weeks the plants  refocused their energy into developing sprouts. The buds are now around 5/8"+ in diameter and still  growing. By sometime in October I'll have fresh sprouts ready to pick.  Occasionally some things I do, work out...

Are Your Tomatoes Ripening Poorly?

Two of my city friends this past week have asked me why their tomatoes were  not ripening completely.  The tops either remained green or just turned yellow.  [There is, of course, a lot about this topic on the Internet already, but we'll deal with their questions anyway...] 

The sympthoms are commonly referred to either  as "green" or "yellow" shoulder respectively, and both are temperature related.   If tomato tops, i.e. the stem ends, remain green, it indicates that  chlorophyll is not breaking down as the tomatoes attempt to ripen due either to prolonged high temperatures or simply too much direct sun exposure (but not enough to cause sun scorch). High temperatures  suppress the production of lycopene, the chemical that makes ripe tomatoes red.   If the stem tops turn yellow, it means that  temperatures have been sufficiently warm  to  inhibit  lycopene production but not so hot as   to stymie the breakdown of  chlorophyll. The result is that  the tomatoes' carotene [yellow]  becomes visible. 

Thus,  one of the interesting contradictions about tomatoes is revealed:  the vines like it hot to grow, but the fruit needs moderate temperatures  between 65°F and 75°F to ripen.  Backyard gardeners who over prune vines or remove foliage to "give the tomatoes more sun to ripen" are actually doing exactly the opposite of what the fruit needs to ripen fully!

FWIW:  Most plants produce carotene; most animals don't.  In plants  carotene absorbs ultraviolet, violet and blue light and  transfers that additional solar energy to the plant's chlorophylls that produce sugars from carbon dioxide and water via the complexities of photosynthesis.  Humans along with most  other animals  obtain carotene either from eating plants or other animals. The carotene then is converted  into vitamin .

You can attempt to  minimize your tomatoes' green or yellow shoulders either by providing some shade  in your garden or you can pick the fruit green and ripen it in your cellar as soon as  you notice that the  fruit is starting to look a little less intensely green. You can also just cut the green or yellow portions off of the fruit and devour the ripe red part.

Although it simply has been hot this year, I know of gardeners and farmers in  rural parts of Rensselaer County whose tomatoes have  ripened okay -- although they have not all escaped  the early onset of late blight. I suspect that we urban/suburban gardeners are just dealing with the effects of the somewhat higher  temperatures that occur in heavily built up areas.

Corn Stalks for Mulch

A community gardener I know this year planted corn mainly to use as a mulch on an adjacent abandoned plot.  She knew that raccoons would probably get most of the corn, and her expectations about the critters unwillingness to share her corn were realistic;   but her decision to use corn to suppress next season's  weeds  suprised me.

Because corn stalks do not compress  much, their fiber  does allow for good aeration in mulch; but unless they are chopped up (or put through a chipper), you will be stepping on the stalks and the cobs for a long time.  In a vegetable garden the problem is that  pests and diseases that are attracted to or reside in corn will be left in your garden.  For this reason corn stalks are better if removed to your compost pile.  Farmers simply either plow the stalks into the ground or use it as feed.  In your compost pile the fibrous corn stalks will also provide a lot of potential carbon. This can balance the amount of nitrogen that fresh green materials, like grass clippings,  abundantly supply.

If you are thinking about what types of mulch you want to use in your vegetable garden or around your ornamental plantings, checkout this U. of Missouri's website about the various characteristics of different kinds of  mulches.

Bags For Butternuts

Several years ago  when I first planted butternut squash in a new community garden plot, I lost a lot of squash to nibbling pests - probably an evil  combination of squirrels, chipmunks and mice.  An adjacent gardener suggested that I cover the squash with paper bags when they were starting to ripen as a means to discourage the nibblers.

Given that I had lots of bags from various sources [because I never throw a good bag away], I tried it the following year.  To my surprise, it did dramatically reduce the damage from these competing harvesters; and I have continued to use the technique since with continuing good results.  The bags will not deter raccoons or the other usual critters from feasting once that the squash have been ripe on the vine for a while, but it buys the squash time to ripen and seems to give me just enough time to  harvest them.   Aestheticlaly, you really don't even notice the  bags while the vines are alive, and they actually keep their integrity through a number of rain storms. Although the bags are biodegradable and could be left in the garden to   decompose.   Because the bags might blow away if not secured, I remove them from the garden and add them to my compost pile when I detach the squashes from the vines.

Garden Preparation:  September

Bacterial wilt and Cucumbers

Last week a friend asked me what happened to their cucumbers seemingly overnight.  They had beautiful vines one day; and the next morning, the plants looked like this photo.  The diagnosis:  bacterial wilt caused by Erwinia tracheiphilia. It can also affect other squashes and pumpkins.

This villain is spread by both the spotted and striped cucumber beetles. The bacteria reside in the insects' digestive tracks; and when the insects pierce the leaves or vines to suck the juices, the bacteria are introduced into a plant.  Sometimes, just a leaf or a vine will be infected.  Sometimes, the entire plant dramatically collapses. 

FWIW: Cucumber beetles are about the only insects bothering cucumbers because these beetles are on the only species that have evolved a resistance to the toxins present in cucumber vines and leaves.  

The toxins are called "cucuribitacins" and are present in cucumbers and related plants.  In our garden varieties of cukes, squashes and pumpkins the levels of these toxins have been reduced through selective breeding over centuries.  Such is not the case with those ornamental gourds that you use as part of  Thanksgiving table centerpieces. Don't snack on them...


Harvest Time Starting for Winter Squashes and Pumpkins

Winter squash can begin to be harvested during September as well as pumpkins - although it's better to wait until the end of the month to allow the rinds to thicken.  The squash will keep better if you do.

Whenever pumpkins turn orange they are ready for picking.  When harvesting any vafriety of winter squash, remember to leave a segment (about 2") of their stems attached.  The stems help to keep the fruits sealed as they cure.  Although both squashes and pumpkins can handle light frosts, both need to be harvested before heavy frosts (i.e. temps in the middle to low 20°F's).








Pruning Brussels Sprouts

Another issue that you might have noticed in your garden during August, given the character of this year's   growing season, is the robustness of Brussels sprout plants.  They may have a lot of foliage, but their buds may be undeveloped. This is  due to the very warm temperatures and ample of moisture.

You can still prune the plants  to induce them to channel their efforts into growing those buds by removing the leader from the top of the plants. You can also remove  the lower leaves from the base to about a third of the way up the stalk.

 The plants still have a long growing season ahead of them to grow their buds.  




And also for September, here are a few more entertaining things you can do...

  • Keep weeding -- remove those plants before they release their seeds...
  • Now is a good time to get that soil test -- give yourself a head start for next year. Changing the pH level of your garden, as is true to other amendments, actually takes months. Don't wait until planting time.
  • Got herbs? -- Let some go to seed, collect the seeds and get started early next spring by growing some of your own. Save a couple of bucks.
  • Start that Garden Notebook -- While you may still remember what you actually planted, make a note about whether you liked it or not.  If you saved the seed packet, at least make a note on it  that you either liked it or will never plant it again.
  • Having trouble giving your excess kale away -- your neighbors will appreciate your donating it to a local food pantry or kitchen.


Swiss Chard - A New Bird Food?

I feed birds in our backyard. The feeders are  near the vegetable garden, and for years the feathery beasts have repaid my generocity  by regularly patrolling the garden for insects.  Starting several years ago I noticed that my Swiss chard was being shredded in late summer.  I couldn't detect any insects and so was baffled.  Then late in the growing season last year I noticed that the last brood of house sparrows were mobbing it.  This year I spied the arrival of the fledgling hordes and put bird netting over my row of chard -- just in time.  Now, these sparrows continue to patrol the garden; the chard is safe; and, fortunately, the little mauraders haven't redirected their tastes to some other vegetable.

When I was about nine years old, I had a parakeet that I would feed leafy greens; but I have never noticed wild birds of any other bent exhibiting a similar yen. It seems to be just these late season fledglings that are drawn to chard.  The chard can grow throughout the spring and summer without being molested; but late in the growing season, it is at risk.  Can anyone explain this behavior? I suspect that there is some nutrient that young house sparrows need to  become fortified in preparation for the oncoming of leaner times...


And remember:

    "I once had a sparrow alight upon my shoulder for a moment, while I was hoeing in a village
          garden, and I felt that I was more distinguished by that circumstance that I should have been 
 by any epaulet I could have worn." - H. D. Thoreau
