Weekly Gardening Outlook: Dog Days

This will be a continuing series where we look ahead at the coming week in gardening for the Northwest Arkansas area.

Chloe and chicks
Might as well get the bad news out of the way first.  After two years without harming a bird, the dogs killed two of my young hens.  They haven't bothered the full grown hens, but the little ones darting about apparently stimulated their inner carnivore.  I looked out the window and saw them bouncing around having a great time with one of the hens in Crash's (our male) mouth.  They were harshly reprimanded, shown the dead bird, and then reprimanded again whenever they showed interest in it.  I've kept them chained up when I'm not in the backyard.  It's going to be hard to trust them around the birds again.

Confined dogs
Insect Report:

Flea beetles on an eggplant
Flea beetles attack my eggplants every year, making the small holes in the leaves that you can see in the picture above.  Unless the population really gets out of control, they don't really seem to hurt the plants much.  They are interesting beetles in that, when disturbed, they can hop very quickly like the fleas they are named after.  A dose of neem oil mixed with pyrethrin (aka NeemII) gets rid of them.  These are both organic treatments.

The Japanese beetles are out and trying to eat my green bean vines, apple trees, blueberry bushes, okra, basil, etc.  Above, you can graphically see the effects of the aforementioned neem oil/pyrethrin mix.  The beetles are only out for 3 weeks or so a year, so two or three applications spread over that time will keep them off of my crops.

Japanese beetle on sweet basil
Pyrethrin kills a broad spectrum of insects, including beneficial insects.  The way to protect beneficial insects is to target the beetles by applying it in the late evening after most beneficial insects have quit flying.  Pyrethrin is biodegradable and breaks down quickly when exposed to oxygen.  Neem oil on the other hand lasts for up to a week, but only kills insects that eat plant leaves.  

Butterfly on flowering sweet basil

These basil plants were treated with NeemII less than 24 hours before this picture and video were taken.  They are covered in butterflies and literally hundreds of hoverflies.  The video doeesn't fully capture the swarm of activity, but it's the best I could do.  It's important to use a pest management system that doesn't harm these beneficial insects.  Both butterflies and hoverflies are excellent pollinators (meaning more fruit for you) and the larva of many hoverflies eat harmful insects like aphids.  If I had just dusted these in Sevin dust, I would have destroyed both.

Caterpillar hiding in damaged onion leaf

Looking at my onions, I noticed the ends of a few leaves were missing.  Upon closer inspection, I caught this guy red-handed inside one of the leaves.  I believe it's a leek moth larvae.  I could treat the onions with Bacillis thuringiensis (BT), but after inspecting them closely I only found a few and the onions are nearing the end of their growing season anyway.  I'll just keep an eye on it for now and smash any that I find.  Interestingly, they have not affected my two-year-old evergreen bunching onions.

Garden Report:

Okra
The okra is still in the vegetative growing phase and has not put on fruit yet.  This variety (Perkins Long Pod) will get up to 5-6 feet tall with trunks as big around as my wrist before they are done.  You can see a definite size difference between the plants on the south (left) end of the bed and those on the north (right).  The plants on the north end get less sunlight because they are shaded somewhat by the plants to the south.

Tomatoes
Cherry tomatoes
Roma tomatoes
The Roma tomato plants may not get tall (~2 feet), but they are loaded with fruit.  None of which are ripe yet.  The cherry tomato plant (Super Sweet 100) has just begun to give a few ripe fruit.  Like the Romas, it is loaded with green fruit and blossoms.  No evidence of blossom-end rot this year.  The crushed egg shells (calcium) and straw mulch (conserving soil moisture) seem to be working.

Jalapenos
Bell peppers
The peppers are also loaded with fruit.  The straw mulch has really improved the health of my plants.

Flowering eggplant
No fruit on the eggplants yet, but they are putting on plenty of purple flowers.

Onions with an eggplant in the background
The onions are ready to harvest.  This is indicated when the foliage begins to fall down as seen above.  Click HERE for a previous post on harvesting and drying onions.

Young butternut squash

I have had such problems with squash vine borer (SVB) in the past, that the only squash I'm growing this year is the butternut squash.  Butternut squash is said to be resistant to the SVB.  So far so good.  The vines are 3-5 feet long and are growing up my cattle panel trellises.  

Swiss chard
The chard is doing what chard does.  It's growing with little care or maintenance.  Such a great crop.

Purple-podded pole beans on a trellis
The pole beans are 3-4 feet long and have yet to flower.  The only problem I've had with this variety in the past is with Japanese beetles defoliating them.  I have the NeemII ready...

Turnip
The warm season growing of turnips has been a huge success.  No maintenance and they are ready to harvest.

New growth on the apple tree
The apple tree is putting on some new growth after being hit hard by cedar-apple rust.  I've treated it with Serenade and this is a promising sign.  I plan preventive treatments next spring starting in April.

Blueberry bush
The two blueberry bushes are growing gangbusters.  I mulched them with straw and that seems t have really helped keep the pots from drying out between waterings.

Dead strawberry plants
Speaking of drying out between waterings, the lack of rain combined with 100 degree temperatures and my neglect have killed about two-thirds of my strawberry plants.  The cinderblocks being porous and having one side exposed to air, dry out easily.  They are easily harvested because of the accesibility, but be aware of the drawback to planting inside the cinderblocks.  Being the low maintence gardener that I am, I am ok with this.  The strawberry plants that remain can obviously handle drought better than those that died off, so as the years go on, the genetics of my plants will exhibit drought tolerance.

Jerusalem artichokes (sunchokes)
Amongst those weeds is a stand of sunchokes about 4 feet tall.  They will put on a beautiful display of small yellow flowers in a month and after it freezes, I will harvest the potato-like tubers.


Chicken and Egg Report:

Again, the size differential between these birds who were born the same day and fed the same feed is astounding.

2"x4" wire barrier
The white cornish/rock meat birds have become so heavy that they cannot haul themselves back up the ramp to get to the food and water.  I put a 2"x4" wire mesh across the end to keep them up top, while allowing the hens access to the nest boxes.  The hen's production has leveled off to about 4 eggs per day.

Out in the proverbial cold
When I put the wire in a week ago, more than half of the egg laying chicks were able to squeeze through the wire and come and go as they pleased.  Just a week later, they have grown such that only two of them can still fit through.  The ones that can't fit through, spend their days foraging in the yard for insects, worms, and vegetation.  We've mysteriously lost two more of them (down to 7).  I can't blame the dogs.  Since I found no feathers or other remains, my money is on hawks.  I'm going to let the dogs run free again as a deterrent to the hawks.  We'll see how that goes.

Weather Outlook:

-We finally got a break from the heat and got a little rain to boot!  Temperatures will remain in the mid to upper 90s this week with little further chance of rain.  Keep your gardens watered.

What's Being Harvested:

-Cherry tomatoes
-Turnips
-Herbs
-Serrano, jalapeno, and bell peppers
-Green, yellow, and purple onions

Weekly Gardening Outlook

This will be a continuing series. Each Monday we will look ahead at the coming week in gardening for the Northwest Arkansas area.

The tide has turned in the war to protect the pole beans from Japanese beetles.  After two treatments with neem oil in one week, the beetles are nowhere to be seen.  The pole beans lost maybe 25% of their foliage, but these hardy vines are still producing and will recover just fine.  If you're using neem for the first time, be aware that it takes 5-7 days to work. It doesn't kill on contact like some chemical poisons.
        
We've been having an issue with leaf spot on some of our potted blue berry bushes.  We came across an organic anti-fungal product called Serenade and after a short period of time using it, we are pleased.  Since using it, the bushes have been able to put on uninfected new growth.  Serenade treatments combined with manually removing the affected leaves (seen in the bottom of the picture) should limit future fungal disease issues.  It is also effective against early blight in tomatoes, powdery mildew in cucurbits (cucumbers, squash, melons, pumpkins, etc.), and any other fungal disease.  Next year, we will periodically pretreat susceptible garden plants  as a preventative measure.

What is it and how does it work?  It contains a probiotic (Bacillus subtilus) that infects and destroys fungal spores.  No spores, no disease.  Also, by colonizing the plant's surface, it will reduce bacterial disease problems through increased site competition.  As mentioned earlier, it is approved for organic gardens and will not harm beneficial insects, pets, or children.

This is not from our garden and it's not a pumpkin.  We bought this unusual watermelon for a reasonable price ($6.50) from a local grower at the Fayetteville farmer's market.  The grower says it came from their local family farm and that her father developed this variety over the course of 25 years of experimentation.  Very cool.  We couldn't pass it up.  It has a firm, juicy flesh with good flavor.  It's much too large a melon to grow on trellises in our current garden, but we've saved the seeds and will give them a go after we move to a larger, more rural property.


Things to be on the lookout for:


Meet the harlequin bug.  At about 5/8" long and with its bright colors it is hard to miss if it's in your garden.  The key to identifying it is the deep V shape on its back.  It prefers to feed on turnips, broccoli, kale, collards, and radishes, but will attack other crops like tomatoes, eggplants, and potatoes if their numbers get high enough.  The harlequin bug sucks fluids from plants and, if there are enough of them, can kill the plants.  The first line of defense in controlling them is to search the underside of leaves and stems for the black and white eggs seen here and to pick off and destroy any adults found.  They aren't particularly fast, so this is fairly effective.  If the numbers have gotten too high, use a quality insecticidal soap.

Weather outlook:
-Low 90's (Keep your gardens well watered during these dog days of summer)
-Chance of scattered showers early in the week
-
Ten day forecast

What's being harvested:
-Green beans (Japanese beetles have slowed production a little, but not much)
-Peppers (Really loaded down with new peppers)
-Watermelons
-Chard and kale
-Onions (Just a few left in the ground)
-Tomatoes (Picking several pounds a day)
-Cucumbers (Getting several a day)
-Squash and zucchini (Squash vine borer has hurt the harvest, one strong vine remaining and several young vines starting to grow)
-Squash blossoms
-Celeriac leaves, basil, mint, and other herbs (all going strong)

Weekly Gardening Outlook

This will be a continuing series. Each Monday we will look ahead at the coming week in gardening for the Northwest Arkansas area.


        
The onions are ready to be harvested.  Look for more discussion of onions later in the week.  The paste (cooking type) tomatoes are coming online.  The garlic is harvested and put up.  Peppers are starting to pop.  What does that add up to?  Well, almost any Italian dish really, but for us it's salsa making time!  The cilantro has all flowered due to the heat, so we had to resort to buying that at the local store.  Next to watermelons, fresh salsa is the best thing about summer gardening.  


     Flowering cilantro

In anticipation of the coming harvests, we are freeing up freezer space.  Last summer we raised 15 hens and 25 roosters.  We kept the 6 best looking hens and put the rest into the freezer.  We tried to keep the best two roosters around, but in our opinion, they just made too much noise for a suburban environment.  We are pressure canning the remaining meat.  Chicken salad anyone?



Things to be on the lookout for:



Japanese beetles are out in full force.  As we've discussed before here, they can be kept at bay on medium to small plants with a jar of soapy water and diligence.  On our pole bean arbor and large apple tree, this just isn't possible.  Too much real estate and too high up.  Being busy people, we let the beetles get a head start on our apple tree.  They did this much damage in a little over a week!  The tree will survive, as it has past attacks, but it now has much less foliage to gather the sun's energy.  The result will likely be smaller apples.  They are just now attacking our pole beans and we aren't going to go down without a fight.  So how to deal with this problem organically?  Our old friend neem oil to the rescue.  A twice weekly application should hold them off.  We are also attacking them on another front by spreading milky spore on the lawn.  This is a bacteria that invades beetle grubs and kills them within 1-3 weeks.  When that grub dies, it releases even more milky spore to take out other grubs.  This method is organic and safe for pets and children.  We'll keep you updated on our progress.

Weather outlook:
-Low 90's
