White Vegetables in My White Garden

It’s been six years since we moved to Boulder from Lincoln, Nebraska. I had a white garden there, and had begun to miss it.

Because some dirt work needed to be done around a basement window this spring which had been the source of some leaking during heavy rains and the flood last fall, my husband added to the project by removing a rectangle of grass around that window well so that I could again have a white garden. The spot is very harsh here in this climate, receiving only afternoon sun.

For the new garden, I started white zinnias, shasta daisies, and phlox from seed. I also ordered some white blooming prairie plants from High Country Gardens. And, because I expected that in its first year, the garden would be sparse, I thought I’d put white vegetables on the one end. For this, I started some chives, white pumpkins, and white eggplants from seed. Needless to say, the pumpkins took over more than their share of the garden by early August but when I harvested them a couple weeks ago, I was not sorry.

Here, I must put in a plug for the source of my seeds, John Sheepers Kitchen Garden Seeds, because all of the seeds from them which I used to start this garden were true. They were white and they all turned out to be what they were supposed to be. I can’t say that for other seed starting experiences I’ve had in the past and it’s a lot of work to start seedlings and nurture them into garden plants. You don’t want to waste your time with poor seeds and who can you trust?

We’ve only had a light frost here so far, and my white garden is blooming very nicely on this mid-October date. It was well worth the effort. Yesterday, I planted white bulbs into it: crocus, daffodils, and tulips. I can hardly wait for next year and it hasn’t even frosted yet.

Here are a few photos for you.

As you can see, we’re more than ready for Halloween at our house!

Leaf Illustrations and Charts to Help Diagnose Plant Nutrient Deficiencies

For the farmer or gardener, it is important to be able to read your plant. The seasoned grower develops an intuitive sense over time in response to plant signals of stress. The key is observing and being able to notice unhealthy leaves, and developing the ability to understand what the plant’s leaf is telling you. Something to note is that a young leaf’s message differs from an old leaf’s message. In this post, I have assembled a number of good graphics to help you do just that. While there is some overlap between the illustrations, they should be helpful as a whole in helping you figure out your specific problem.

What is a Keyhole Garden?

A keyhole garden is a type of raised bed that contains compost and it is higher in the middle so that water flows into the growing bed area. These gardens are being taught to African farmers and they are becoming more popular in drier regions such as parts of Texas. They are popular among permaculturists, too. The following video explains how to make one.

20 Organic Recipes and Products to Control Bugs, Pests and Weeds

It is that season when those of us who garden or farm try to protect our produce and crops from a very long list of pests. Below, I’ve compiled a list of 20 products, hints, and household recipes which may be useful to you in combatting the pests and weeds in your garden.

1. Orchard/Apple tree pest recipe: You need an old cleaned plastic gallon milk jug. Cut a 3 inch diameter hole on the side-top, leaving the jug’s handle intact. Add to the jug a banana peel, 1 cup of sugar, and 1 cup of apple cider vinegar. Add a few cups of hot water and mix until the sugar dissolves. Hang 1-3 of these prepared jugs near the trunk of your apple tree. Replace the solution as needed throughout the summer, starting early. (My sister-in-law swears by this and has used this recipe for 20 years in our farm’s wonderful old McIntosh Apple tree.) Try on any other fruit tree, too, especially pear and cherry.

2. To kill weeds use a 10% vinegar spray (is about twice as strong as household vinegar). You may add a little soap, too.

3. Clove oil works to kill weeds and bugs. It is best for wide-leafed weeds. To make clove oil weed spray, pour 10-20 drops of clove essential oil into an empty spray bottle. Fill the remainder of the spray bottle with tap water, close tightly and shake well. Use as needed. Clove oil has fungicidal, herbicidal and insecticidal properties in addition to being a weed killer.

4. Herbicidal and/or insecticidal soap based products such as “Safer” are available commercially. Non-toxic herbicide sprays are more effective if you spray the weeds when they are young and during full sun. Get the tops and the undersides of the leaves.

5. Dried or liquid molasses can be used to kill weeds and insect pests including fire ants. It also enriches the soil. Apple cider vinegar and molasses have been used together to fight fungal diseases.

6. Fill a milk jug half-full with water and add 1/2 cup of milk. Use in a spray bottle to control powdery mildew.

7. Home Recipe for Bug Spray #1: 1 teaspoon vegetable oil + 1 teaspoon dish soap + 1 teaspoon baking soda. Add to a quart of water in spray bottle and shake before using for aphids and other bugs.

8. Home Recipe for Bug Spray #2: Mix several cloves of crushed garlic, ¼ cup canola oil, 3 tablespoons hot pepper sauce and ½ teaspoon liquid soap in 1 gallon of water, mix well. Put into spray bottle, shake well before using.

9. Home Recipe for Bug Spray #3: Blenderize or finely chop one garlic bulb and one small onion. Add 1 teaspoon of powdered cayenne pepper and mix with 1 quart of water. Steep 1 hour, strain through cheesecloth, then add 1 tablespoon of liquid dish soap to the strained liquid. Mix well. Spray plants, including leaf undersides. Store the mixture for up to 1 week in a labeled, covered container in the refrigerator.

10. Use boiling water to kill weeds in sidewalk cracks.

11. 4-Legged Pests: 1) Keep out deer, rabbits, raccoons, and cats by placing rags soaked in white vinegar on stakes around your vegetables. Re-soak the rags every 7-10 days. 2) For deer, blend 2 eggs and a cup or two of cold water at high speed. Add this mixture to a gallon of water and let it stand for 24 hours. After 24 hours, spray on foliage. The egg mixture does not wash off easily, but re-application 2-3 times a season may be needed. 3) For deer, mix together 1 tablespoon of baking powder + 1 egg yolk + 1 litre of water. Spray plants every 2-3 weeks. 4) Use the ScareCrow motion sensor water sprinkler. 5) Use Nite Guard Solar lights which are motion sensored to scare away your night time visitors.

12. Tobacco as pest repellent for caterpillars, aphids, other insects, rabbits, and slugs: Soak 1/2 cup chewing tobacco in 1 cup Listerine mouth wash plus 2 cups water for 1-3 days. Strain, and spray affected plants.

13. Marigolds and nasturtiums help control bugs by attracting them, so intersperse these flowers through out the vegetable and squash garden. For the squash bug, try to plant resistant varieties such as the butternut, acorn, zucchini, and cheese squashes, or set traps, such as cardboard or flat rocks under the plants. They will hide under the cardboard or rock, and then you can destroy them.

14. Use salt or salt water to kill slugs.

15. BT spray works well for worm prevention for the cruciferous vegetables like broccoli, Brussels sprouts and cabbage. If you see those little white butterflies in your garden, get the BT spray out. (See top photo) Bioinsecticide BTSD spray works for very young potato beetles, too.

16. Mulches: To kill or prevent weeds, use corn meal, or, corn gluten meal mulch which also provides nitrogen fertilizer while smothering out the weed seeds. Chipped wood mulch 2-6 inches thick helps control weeds. Gravel mulch works well for xeriscape plantings. Hay or straw mulch is good in the garden, but remember it may contain seeds. Shredded leaf mulch (cold mulch) in the fall improves soil microbiota and fungi. Or, organic farmers commonly use black plastic (mulch) around row crops to prevent weeds.

17. Flame weed propane torches can be used to kill weeds.

18. For mechanical weed removal, experiment to find your favorite hoe or tool. There are many kinds on the market, with both long and short handles. I love the short handled Japanese Nejiri Weeder hoe. A great gardener friend prefers the winged weeder; another, the stirrup, or scuffle hoe.

19. Row crop cover fabric helps control insect pests. It may be used on potatoes or squash or any crop being plagued by insects.

20. For a bug repellent for yourself as you work in the garden, try mixing lavender with vinegar. Put dried lavender into a bottle and add 2 cups of vinegar. Let set for a week to infuse. Strain to remove lavender. Dab on skin when working outdoors. For a natural fly repellent for cattle, try pyrethrin (an extract of chrysanthemums) sprays. Or, make your own natural fly sprays by combining one cup vegetable oil, two cups vinegar, one cup water and one tablespoon essential oil (clove, eucalyptus, mint, citrus or citronella).

Alegría Fresh: A Prototype Urban Farm in Irvine, California Uses GardenSoxx

A commercial venture is on the move, and its timing is great, as it proposes to save water, fertilizer, and space, while providing fresh, nutrient-dense produce in urban areas.

This Southern California company is setting up an urban micro-farm -which claims to save large amounts of water- in Irvine, California during this time period when the extreme-drought of California is grabbing so many headlines.

The company is called Alegría Fresh, and they have various products on the market which are intended to grow fresh produce by using hydroponic techniques.

They have devised a mini-vertical garden system for urban dwellers for use in small spaces. Their vertical farm set-ups use coconut fiber (coir) instead of soil.

Their latest venture, Alegría Soxx Farm, uses 7500 linear feet of GardenSoxx on one-fifth of an acre in Irvine, California to grow 15 different vegetables, for a total of 13,000 plants.

They expect a 70 percent reduction in the amount of water needed to grow this produce, and a 50 percent reduction in fertilizer required because of the rich growing medium used. They also expect high yields, greater pest resistance, and faster growth rates, calling this a “paradigm shift in urban ag”.

Furthermore, they suggest that this prototype farm, and other future urban micro-farms like it have a juice bar, salad bar, and small farm stand alongside it to sell produce direct and employ local workers, creating a revenue stream that can support the farms.

All Sounds Great, But a Few Comments . . .
One question that I have, should any of the fine folks from Alegría drop by and read this, is how does this farm save water, when the GardenSoxx Q&A states, “as the mesh breathes, it will dry out sooner than normal soil.” I’d love to see an answer in the comments below, please, as many people are looking for solutions such as this to help grow food in our urban areas.

My other question is how adaptable would this system be to other regions of this nation, besides our prized Mediterranean climate growing region of Southern California?

Finally, I love innovation in food growing, but how I wish it didn’t (so often) involve greater use of plastic.

UPDATE: I’ve noticed the video isn’t working, which really is necessary to understand this set-up. See this page for another video. And here is a video of their vertical hydroponic gardening system.
