Prepare Now For Fall/Winter Vegetable Harvest by Keith C. Hansen

All of this heat reminds me of a line from an old country song – “It’s too hot to fish and too hot for golf”.  Unfortunately for those of us that garden in Texas in the fall and winter, it is not too hot  garden.  I spent about eight very hot and sweaty hours in the garden this past weekend getting my garden ready for the fall and winter.  If you have not already started your garden you are a little behind schedule.  My friend Kieth Hansen recently retired from his role as Horticultural Extension Agent in the Tyler area.  While doing some reading last week I came upon an article he wrote a while back that does as good a job as anything I have ever seen at helping you prepare now for your fall and winter harvests.  I was so impressed with the article that I asked if I could rerun it here.  Kieth is an outstanding horticulturist and an outstanding writer.  Once you read this I am sure you will want to jump over to his website,  East Texas Gardening blog, and check it out.

Prepare Now For Fall/Winter Vegetable Harvest by Keith C. Hansen

 

Mid-July means two things: the dog days of summer and fall vegetable gardens. Everyone can relate to dog days – it’s hot and humid, good only for dogs to find a cool spot to dig a hole.

But fall gardens? In July? That’s right! Mid-Summer is the time to begin preparing and planting the garden for a fall harvest.

The first key for a successful fall garden is to get the weeds out. And if Bermuda or bahia grass are among those weeds, you can’t just rototill everything under because once you start watering and fertilizing again, you’ll have the greenest lawn in town.

Solarization is one method to reduce weeds, and other pests, by using the sun’s energy to pasteurize the upper layer of soil. However, this takes time. Prepare the soil, removing garden debris and weeds, form your beds, and then thoroughly water the soil. Cover the prepared area with clear polyethylene, sealing the edges with soil, to trap the sun’s heat. This doesn’t sterilize the soil, but reduces populations of harmful nematodes, weeds and other pests. It’s critical that his is done during July and August, the hottest time of the year. Treat for at least 6 to 8 weeks. You won’t get to plant tomatoes or peppers, but the garden site will be ready in time to plant cool-season vegetables. Solarizing-Weeds

Another non-chemical method of killing weeds is to smother them under 6 to 8 layers of wet newspaper, and then cover this layer with pine needles, old hay or grass clippings. Whenever weeds like Bermuda grass shows up through the edges, place another layer of paper over it. By continually denying them light, they’ll eventually weaken and die. Transplant through the papers, or just use them in the pathways. The paper will be mostly decomposed by next spring.

using newspaper and mulch is a great way to smother weeds in your garden

Hand digging is another option for real small plots, but take care not to get heat stroke; work early in the morning before it gets too hot.

If the garden spot has perennial weeds, like Bermuda, you can spray the weeds in an empty garden site with a weed killer that contains glyphosate. Some brand names for glyphosate include: Roundup, Kleenup, and Weed Away. Check the ingredients on the label for the term glyphosate” and follow label instructions for application rate. Glyphosate will not stay in the soil; it is strictly a foliar weed killer, but it kills roots and all. It takes about 2 weeks to completely kill Bermuda, maybe slightly longer if the weeds are under drought stress. It works best if weeds are healthy, actively growing and not suffering from lack of water. Remember, the garden spot must be empty to use glyphosate! Read the label completely before using.

While not as effective as Round Up, concentrated acetic acid is a good, organic weed killer that will work on both grassy and broad leafed weeds

There are also organic herbicides formulated with oils and soaps that will kill many tender annual weeds, but will not eliminate Bermuda and other perennial weeds with one application.

For future weed control, once you have your garden prepared, always maintain some sort of mulch covering the surface of the soil to prevent weeds from taking over again.

Every time you prepare the soil to plant a new crop, always mix in as much compost as you can get your hands on. Add well-decomposed animal manure, fertilizer and lime if soil tests indicate a low fertility or pH, and work all ingredients into the soil.

Compost helps sandy soils retain moisture and clay soils drain. It also supplies plant ready nutrients slowly and consistently.

Southern peas such as blackeye, purplehull, cream and crowders make a great, edible summer cover crop for building the soil and providing food. The pea vines can be mowed and rototilled under while still green for extra soil building benefits or allowed to produce peas and then tilled under.

Tomatoes and peppers need to be planted soon – by the first of August – if they are going to make a good crop before first frost. What if your garden spot is not yet ready? Buy your transplants now and grow them in a larger container to plant in the garden later.

*****Check out our planting guidelines in the sidebar to see when you need to put out your favorite vegetble seeds and transplants.

Get either 6-pack transplants or 4-inch transplants. Put them in a 1- or 3-gallon nursery container filled with potting soil. Do not use soil from your garden. Add slow release fertilizer (like Osmocote or other slow release formulation) to the soil mix. Set the pots in a sunny spot in the yard, not in the shade!

When watering seedlings uses a water soluble fertilizer or compost tea

Every time you water, use a water-soluble fertilizer solution instead of just plain water. Your transplants will continue to grow and be healthy, just as if you have transplanted them directly into the ground. Once your garden site is ready, you will have large, healthy tomato and pepper plants to set out. They will be easier to take care of and you will be assured of a bountiful harvest before the first freeze of winter.

Grow fast maturing tomato varieties for the fall harvest. Look for varieties with less than 75 days to maturity, such as ‘Merced’, ‘Bingo’, ‘Celebrity’, ‘Whirlaway’, and ‘Carnival’. ‘Surefire’ is a smaller, processing tomato variety (with thicker skin) which sets and matures all of its tomatoes very quickly, giving you a “surefire” harvest that beats the first freeze. Most cherry tomatoes will bear within 65 days of transplanting.

Timing is very important for a successful fall garden. Heat tolerant/cold sensitive crops need to be planted in time to mature before cold weather slows and stops growth, while cool season/heat sensitive crops are planted late enough to avoid the heat, but early enough to take the first frosts of winter.

Seeded vegetables can be tricky to get up in the heat of summer. Soil often forms a crust on the surface after tillage and watering. This “crust” can hinder tender seedlings from breaking through. Here are a couple of tips to help get seedlings up in the summer.

Open a furrow down the row as you normally would to sow the seeds. Before sowing, take your garden hose and thoroughly soak the bottom of the seed furrow with water. Next sow the seed. Finally, cover the seed to the proper depth with dry soil and firm. The seed should stay moist enough until germination, and if you avoid overhead watering, the soil will not form a crust to hinder seedling emergence.

Other folks will place a board or wet burlap over the seed row to provide constant dampness to encourage germination and emergence. You need to check every day for signs of emergence, and remove the covering when you see the first seedlings breaking through.

Fall Into Winter Vegetables on Central Texas Gardener

If you have questions about what to grow in the fall and winter garden, then this week’s episode of Central Texas Gardener is perfect for you.  Patty and I were thrilled to be invited to talk about fall gardening on this award winning  PBS (KLRU) television program.

In my opinion Fall is the best time of the year to garden in Texas.  The temperatures are milder and the weeds are not nearly as aggressive.  Plus, you can grow so many great vegetables!  While it is a little late for tomatoes it is the perfect time to plant broccoli, cauliflower, cabbage and Brussels sprouts.  It is also a good time to plant root crops like beets, carrots, turnips, radishes and parsnips.  It is also time to start your salad greens.  Fall and winter are the ONLY time you can grow your lettuce and spinach in Texas. danvers-carrots

I have been a fan of CTG for years.  Growing in Texas is challenging and their experts and guest always have the right answers for the problems I am dealing with in my own garden.  If you are not a regular viewer, or you do not get CTG on your local PBS channel, go to their website (http://www.klru.org/ctg/ ).  Each and every segment they do is available on YouTube on their site or on their YouTube Channel.   texas-lettuce

This was my first time in a television studio and I was a little nervous.  However producer Linda Lehmusvirta and host Tom Spencer (and the Hays County Master gardeners) made the whole experience so much fun.  I would also like to thank all of the people behind the scenes at KLRU for making Patty and I feel  so comfortable in front of your cameras. Heck, I didn’t even get offended when you had to put make up on my bald head to kill the glare!

Many thanks to the whole KLRU, and the Hays County Master Gardeners for a truly wonderful experience!

2012 Fall Gardening Tips

Right now it is so hot outside I work up a sweat just walking to the garden.  Photo by Heather White

August 1 is the official kick off date for fall gardening in my part of Texas.  In reality, I actually start working on my fall garden around the middle of July.  Like most of us in zones 7-9, my tomatoes are basically done by July 4th.  When your spring tomatoes stop setting fruit you have two choices.  Pull ’em up and replace with new plants in August, or trim your exisiting vines up, give them a little shade, a few nutrients, and wait for the temperatures to drop.

In my opinion, the best way to ensure a fall tomato harvest is to keep your spring plants alive through July and August. These mature plants will flower and bloom much faster than new plants put out in August.

Ever since the November night that I was late to my anniversary party because I was building cold frames out of old windows around the tomato plants I planted in August, I have been in the tomato trimming group.  Little tomato plants planted in the 100 degree August heat will not always produce red ripe tomatoes before our first freeze.  Because of this, I try and keep my spring tomato plants alive through July and August.  To keep my spring tomato plants alive, I prune them by about a third to a half in mid-July.  I then add a thick layer of composted chicken manure, mulch and put up some sort of shade.  For me, this has been the best way to ensure a harvest of a few fall tomatoes.

While I am out trimming tomatoes I also do a good garden clean up.  July is when I pull down any vines on my trellises that have stopped producing.  This can included beans, gourds, cucumbers, cantelopes and squash.  I also pull up any old mulch that is still lying on top of the ground.  I take all of this dead vegation directly to the burn pile.  Many of those bugs that caused you so much grief earlier in the year are sleeping and laying eggs in the mulch and plant liter under your plants.   Because of this, removing it and burning it twice a year is a good pest control measure.

Put out a fresh layer of compost on your clean Fall beds. Animal manures like cow manure and chicken manure are a little higher and nitrogen than the palnt types. I use these to give a boost to my newly trimmed tomatoes.

After my beds and trellises are clean, I amend the soil.  I add about 3″ of whatever compost is on sale to the tops of my beds.  I don’t usually till this compost in.  I actually kind of use it as mulch.  The compost will eventually get worked in when I plant or it rains or through the natural processes of all of the tiny little animals in the soil that feed off of the compost.

Finally, to conserve moisture, cool remaining roots and protect all of those micro-organisms in the soil I add a fresh deep layer of hay mulch.  If you mulch with hay you need to be careful.  Alot of herbicides that farmers use to control weeds in their hay crops are very persistent.  There can be enough residue is some hays (particularly bermuda hays like coastal, Tifton and Jiggs) to kill your new plants that are trying to germinate or become established.  I typically use rice straw as my mulch.  In my experience rice hay has no residual herbicides and very few weeds.

A large $70 roll of rice hay will supply me with all of the mulch I need for an entire year of gardening

After doing all of this prep, I spend a lot of time on the internet figuring out what I am going to plant and when I am going to plant it.  This year, I found the best planting guide/calendar I have ever seen.  This guide is on the Austin Organic Gardeners  website.  (they also have one for herbs).  Instead of a list of dates, this calendar is a graphical representative of the entire year.  It’s easy to read format allows you to quickly look up any plant you want.  The headers show every month broken down into weeks and the rows are an alphabetical listing of all of the vegetables we can grow in this area.

This very good planting guide is on the Austin Organic Gardeners website. This graphical guide is the easiest to use that I have found. They website has one for herbs as well.

My grandmother used to say you could find something nice to say about anything.  So, I am going to say something nice about Texas summers.  Even though it is 106 in the hot Texas sun right now, that sun is what is going to allow me to grow some of my favorite vegetables over the next six months.  I know it is hot out there, but now is the ideal time to get that fall garden going.  All of the sweat of July and August will pay off big in September and October.  So suck it up and get busy.  You will forget all about how hot July was when you are OUTSIDE in your garden harvesting broccoli, cauliflower, collards, and cabbage in January!
