Great Christmas Gifts for the Gardener

Great Gifts for Gardeners from the December Northern Gardening Radio Show

 

Here are some of the ideas ---

 

Tools:

• Yard Butler’s GKS-2 Garden Kneeler and Seat

“I bought one of these about 2 years ago at Buck’s Hardware because I am getting older and it’s harder for me to get up and down in the garden. Wow! What a difference this kneeler/seat has made! I bet it has given me at least another 10 or more years of gardening life! I love it! I bet Buck’s would order it for those who want to shop local. Otherwise you can order one on Amazon.com. I have seen them for sale in seed catalogs as well. Deep Seat Kneeler (Gardeners Supply Company carries them.) The cost will range from $29 - $39.95. You can also add a tool pouch kit to put your pruners, knife, markers, twine, etc.”

Hori-Hori Japanese Weeding Knife

This is probably one of the most useful tools for gardening we’ve found There are two different kinds. You can get it in stainless steel or carbon steel. The handle is wood and very sturdy.

The Hori-Hori (which means diggy-diggy in Japanese!) blade stays sharp, smooth, and rust-free, and it has a sharp side and a serrated side for cutting through landscape fabric or tough roots. The tip has a sharp point, so it goes into the soil smoothly and can get weeds with long taproots out. 

It’s great for planting annuals or six- packs, too, and just running underneath the soil to destroy tiny weed seedlings. 

Stainless steel blades work better in  clay soils, since the clay sometimes sticks to the carbon steel. And the stainless steel blades are sharper. On the other hand, the carbon steel is a heftier tool, and can be used for bigger jobs.

Either are highly recommended. A great gift.

$28 -$32 Duluth Trading Company or Amazon.com 

Soil Scoop puts the digging ability of trowels to shame. It’s got a great scooping portion, with serrated edges and a sharp tip so you can break up harder soil, enlarge planting holes, or get out weeds. If I did a lot of veggie gardening in raised beds or annual flower bed planting, this is the tool I’d pick up. (And HURRAH! It comes in purple! You can also have a nice birch wood handle.) $19.95  at Lehman’s but lots of other places like Burpees, etc.

Tub Trugs. When I first started gardening I didn’t think about good containers to put produce in or carry fertilizer or mulch or anything. I would use what I had – a bucket or a basket. They really didn’t work very well. I really like those Tub Trugs. They come from Spain. They are like a flexible bucket with strong handles. The original ones are made from 100 percent Food Grade plastic. They are frost and UV resistant. They come in sizes ranging from 1.3 gallons to 11 gallons. Some are taller and deeper and others are wider and squatter. Some places that sell them offer plastic covers as well for an additional $8. They come in fabulous bright colors, blue, red, green, yellow purple, and can range in price form $10 - $22. Gardener’s Supply Catalog has them, but so do lots of other places.

Agribon or Floating Row Covers: 83” x 50’ Insect control $19.99 – Frost protection $29.99.

(Peaceful Valley Farm) 118” x 50’ $23.95 (Johnny’s Selected Seeds)

•  Excalibur Dehydrator Deluxe 3000 Series (BPA free plastic) Easier to clean, 10 year warranty, even dehydration, heavy duty motor, adjustable thermostat, etc. $250. Harvest Essentials, Peaceful Valley Farm & Garden Supply, on-line…

•  Felco By-Pass Pruners #6 Fits better for smaller hands, weight 7.5 oz. Best for flower growers because you can get closer to the stem of the plant. .8 inch diameter for cutting. $45

Felco 2 Pruner Works well with larger hands. Can cut up to 1” diameter with weight at 8.5 oz. $49.00 Both can be purchased at the Felco Store as well as other places. They have a limited lifetime.
 

Other tools and things for the garden:
• Promise to build a small greenhouse or a raised bed or two.

Electric roto-tiller

• OXO Good Grips Green Salad Spinner: Push the top down and spin the lettuce dry.$30. There are available at Target, etc.

Garden/English/Potato Fork: Garden forks are designed for either digging or scooping. The number and shape of the prongs (known as tines) depends on the intended use of the fork. I like the broader tines with a sharp end on them for digging potatoes or breaking up clay. Forged from a single piece of steel will make them last a very long time. $99.00 Johnny’s

  Soil Thermometer: $11.95

Compost Thermometer: $31.50

Bug nets /head nets: $8.95 ;

Walls-O –Water: perfect to keep tomato & pepper plants warm and toasty in June and July.  18” tall x 17” diameter $13.95, many seed catalogs carry them now.

Gift Certificates to favorite seed companies like Seed Savers, Seed of Change, Johnny’s or Fed Co.

Colored Twine Gift Pack, Gardeners Supply, 8 different colors of twine, 50’ of each color, great for both fun and practicality in the garden. $9.95.

• Garden Markers. I like the small plastic 6” markers. If you write on them with pencil, you can erase

and keep reusing. Wooden ones don’t seem to not hold up. If you use them outside, use a UV garden marker $4.25 Templars, Permanent Copper Plant Tags ‘Engrave with ball point pen. 20 for $6.95. Gardener’s Supply. 

Nitrile Gloves: You want the thin, flexible ones and you want to by them in a 4 – 6 pack because everyone loses them. They come in different sizes and sell for $16 -25. Single pairs for $4 – 7. They can be found many different places both locally and on-line.

•  Deep Rim Boot Trays: If you have mud, kids, grand kids. 21 2/3” wide x 2” deep by 43 ?” long. Two rubber grids go inside. $35.00 Gardener’s Supply Company This also works for snow.
 

Local Gardening Gifts:
Gift certificates to Buck’s, Hilja’s or the Blue Moose for plants/ seeds, garden art.

• Gift Certificate for bags of Black Gold, Western Lake Superior Sanitary District’s incredible compost. Buck’s carries it. ($5 for a 40 lb) etc.

• A personal gift certificate for an hour of weeding and/or watching children so a gardener can enjoy planting the garden by themselves;

Soil testing to the U of M is $15. Pick up a form at Extension, Buck’s, on-line by googling ‘U of M Extension soil testing’. They have forms you can print directly. Put the form and the $15 together in an envelope and you have a great gift!

• Support local producers. Buy local jams, jellies, maple syrups, wild rice. Great stocking stuffers. 

 

Tools to process all those veggies:
• Cabbage cutter for making kraut, 

• Vegetable Brush: $2.95
• A set of good cutting and paring knives.

• Canning jars, water bath for processing jams/ jellies, pressure canner for beans and corn.

 

Unusual, fun gifts in the West End: 

1. Water’s Edge: Plates of fused glass with flowers gorgeously arranged in the glass made out of glass. Very unique and different for that gardener who loves the one-of-a-kind gift. $21+

They also had candles with scents from honeysuckle, tuberose, peony, sweet pea, etc. $13, Butterfly wing earrings from Butterfly Artworks.

2. Caribou Highlands: Maple leaf sticky notes in bright red $8.95; delicate soap leaves in the shape, thinness, size of leaves $9.85.

3. Mountain Shop: Morning flower earrings $14.95 - $24.95 Fresh Jewelry made from actual flowers $26.95. Healing touch pottery with a worry stone on the top of the handle $24.95.

Birdhouse ornaments $11.50; Klutz makes a wristlet purse in the shape of a chicken complete with feet for that unusual child who loves having chickens in the garden. $15

There are lots of other great gift ideas, but these were suggested by local gardeners for local gardeners.

Happy Holidays from Joan and Diane!

Square-foot gardens can be very productive

Tips on how to handle our insect invasions & Charlie Butter on square-foot gardening

AttachmentSize
Nor Gard_071212.mp3111.19 MB

This month, Northern Gardening hosts Diane Booth and Joan Farnam talk to Jeff Hahn, U of M. Extension entomologist and author of “Insects of the North Woods” about the insect invasion in our gardens this year, and local gardener Charlie Butter talks about his square-foot gardens and a new vegetable garden project at the hospital that he has developed.

Some garden insect pests that are being seen this year in Cook County include the following:
1. Flea beetles
   • Numerous species: striped flea beetle, western black flea beetle, spinach flea beetle, potato flea beetle
   • 1/16 – 1/8”
   • Black, bronze, bluish or brown to metallic gray, stripes
   • Large black legs used for jumping when disturbed
   • Overwinter as adults in the leaf litter, etc.
   • Early spring adults lay eggs in small holes in roots, soil, leaves
   • Common on radishes, broccoli, cabbage, turnips, eggplant, peppers, tomatoes, potatoes, spinach, melons,
   • Following egg hatch they feed on roots – little damage except to potatoes
   • Adults cause most of the problems feeding on foliage.
   • Typical damage are small rounded, irregular holes usually < 1/8” diameter looking like shot-holes.
   • Monitor with yellow sticky cards
    • Use floating row covers
   • Plant a trap crop – radishes before you plant your main crop

2. Onion maggots
   • A fly (Delia antique) lays eggs in early spring at the base of an onion and in nearby cracks in the soil.
   • The larvae form is what burrows into the onion bulb or lower part of the onion.
   • The foliage wilts or is stunted as the first sign.
   • If you pull the onion you will usually find the culprit burrowed into the bottom part of the onion. They feed on the bulb and rot invades as well.
   • A floating row cover can protect your plants from having the adult fly lay their eggs.
   • Rotate your onions so you don’t plant them in the same place.

3. Variegated cutworm
   • Eggs of the variegated cutworm, Peridroma saucia, were found in large numbers on windows, siding, screens this spring.
   • Apparently, variegated cutworm moths from outbreaks in southern states were blown north over a period of a few weeks in May and eggs were laid at night on emerging crops, gardens, fence posts, buildings, trees and almost anything that holds still long enough.
   • All these eggs will hatch, yielding tiny, translucent caterpillars with a few dark hairs and over-sized, black heads. They will be hungry. And, they have an extremely wide host range: most vegetable garden plants, fruit trees, rhubarb, raspberries, strawberries, ornamental plants, shrubs, hostas, canola, wheat, corn, sunflower, clover and other row crops. Cutworms feed at night and rest during the day so it is hard to find them, but the damage will be easy to spot: seedlings nipped off at ground level and large holes eaten out of leaves all season long.
   • The variegated cutworm is also called the climbing cutworm because mature caterpillar stages will spend both days and nights on their host plants in contrast to most other species of cutworm. After feeding, they'll pupate in the soil, emerge as moths and start another generation, likely in July. Adults created from this generation will migrate south in October to other states in order to overwinter.
• Projections for next year…. what can we expect? Will they pupate and overwinter in our soil, adults fly south to overwinter? If we have a cold winter, the cutworms will not survive it.
   • Variegated cutworms are beginning to show up in alfalfa in SW MN. The variegated cutworm is a migrating moth that makes its way into the region and occasionally arrives early and in large enough numbers to cause problems. Alfalfa is one of several host crops the moths are attracted to for laying eggs. The most distinguishing characteristic of the variegated cutworm is the 4 to 7 pale yellow, circular spots on the back of the larva. Its general body color is variable (olive to nearly black), but usually brown. The underside of the caterpillar is cream colored. There is a narrow, orange-brown stripe along the side.

4. Earwigs
   • Became noticeable in Minnesota in the 1990’s.
   • Forficula auricularia
   • Many areas of Minnesota experienced high earwig numbers last year. Cook County had a high infestation two years ago and we are seeing some again this year. Be on the watch for them in your garden this summer.
   • Earwigs are about 5/8 inch long, with a flat, reddish brown body and very short wings. They look like a cockroach or a rove beetle but are distinctive because of the pair of pinchers (cerci) on the tip of their abdomen. Nymphs are similar to adults except they are smaller and generally lighter in color.
   • They love moisture and usually come out to feed at night.
   • They are scavengers that often feed on decaying plant or insects. They will also feed on healthy plant tissue including flowers and vegetables.
   • The damage often looks like slug damage except there isn’t a slime trail.
   • Oil traps vs. rolled up newspaper traps in the garden. You can set out rolled up newspapers or similar objects to trap earwigs. You can also place old tuna fish cans baited with fish oil or vegetable oil. Set them out during evening in areas where you are seeing earwigs in your garden. In morning, shake the traps above a pail of soapy water to remove and kill the insects. 
   • Keep the top of the soil dry in your garden.
   • Permethrin around the perimeter of your home may help deter them from coming inside. It is best to caulk everything and prevent them from getting into your indoor space.

5. Spotted milk millipede
   • Blaninlus guttinlatus
   • Snake-like slender body (whitish / translucent) with pinkish spots on the side
   • Soil inhabitants that feed on decaying plant material.
   • They have been found here eating zucchini plants – feeding damage to the root system. They can also attack other plants especially when we have dry weather.
   • Last year they were especially bad for one grower in Cook County.

6. Imported Cabbageworm / Cabbage Butterfly
   • Pieris rapae
   • Winter is spent as a pupa amongst plant debris.
   • Adult females lay yellow bullet shaped eggs on leaves.
   • 2-4 generations a year
   • Like broccoli, cauliflower, cabbage
   • Use of exclusion with reemay
   • Bacillus thuriengensis

7. Strawberry Root Weevil
   • Otiorhynchus ovatus
   • Very small, ¼ inch long, black or dark brown with rows of pits along their back
   • Feed on roots of strawberries, evergreens, raspberries, grapes, etc.
   • Adults emerge in early summer and feed on the edges of foliage, leaving a characteristic notched appearance
   • In hot dry summers, they can become invaders in your home looking for cool, damp conditions. They are attracted to moisture.
   • They are being found this year near water on docks, lakeshores and in basements, sinks, bathtubs.

8. Colorado Potato Beetle
   • Leptinotarsa decemlineata
    • Found occasionally in Cook County
   • Adults 3/8” long, yellow and black stripes on back
   • Larvae are reddish / red-orange with a dark head
   • Usually one generation a year
   • Hand pick

9. Potato Leafhopper
   • Empoasca fabae
   • Pale green, 1/8” long, move sideways when disturbed
   • Yellowing of tip of leafs followed by browning, cupping, distortion.
   • ‘Hopper burn’
   • Rose leafhoppers similar, but nymphs cannot move sideways. Pale yellow to creamy white color.
   • White apple leafhopper is also similar.

10. Four-lined Plant bug
   • Poecilocapsus lineatus
   • Adults are yellow usually with 4 dark lines on their back.
   • ¼ -1/3” long / immature forms are bright red-orange with black dots on the thorax
   • Feeding damage is little round circles of necrotic tissue damage

11. Tarnished Plant Bug
   • Lygus lineolaris
   • Adults are generally oval, about twice as long as wide, and about ¼ inch long. Generally brown with some yellow and reddish markings.
   • Feeds on developing leaves, flowers, fruits, killing the areas around the feeding site.
   • Catface injuries to fruit; hard nubbins for strawberries, etc.

12. Tobacco or Geranium Budworm
   • Heliothis virescens
   • Caterpillars can reach 1.5” and feed on flowers and buds. Found in Cook County by holes in geranium and petunia buds.
   • Hand pick or use Bacillus thuriengensis

13. Corn Earworm
   • Helicoverpa zea
   • Migration of adult moths can occur in our county. (Don’t overwinter here)
   • Eggs are laid on the silks of the corn
   • The small larvae tunnel down into the corn and eat for about 4 weeks.
   • Mineral oil on the silks when moths are around?
   • Cut off the damage to the end of the ear of the corn and use the rest.

14. Japanese Beetle
   • Popillia japonica
   • Overwinter as a nearly full-grown grub below frost line in winter.
   • Adults emerge in late June and early summer, feed on foliate, mate, and return to lawn areas. Females lay eggs in small masses in soil cavities 2-4” deep. One year cycle but can extend to 2 years.
   • Adults feed on foliage of more than 300 species: rose, mountain ash, willow, linden, grape, Virginia creeper, birches, ornamental apple, plum, cherry, etc.

15. Aphids
   • 1,300 species+
   • Normal reproduction is asexual. Sexual forms usually occur in one generation a year.
   • Suck sap from the phloem of plants and can cause injuries including transmit viruses, etc.
   • Honeydew that is secreted can be associated with sooty mold.
   • Common: apple aphids; lupine aphids; balsam twig aphid;

16. Leafhoppers carrying Aster Yellows
   • What leafhoppers are most common for this? Aster leafhopper? (Macrosteles quadrilineatus)
   • Phytoplasma that is picked up by the leafhopper, develops for up to 10 days or 3 weeks before it can be transmitted through saliva from the leafhopper to another plant.
   • 1-5% of all leafhoppers carry the aster yellows phytoplasma during the growing season.

17. Gladiolus thrips, iris thrips, daylily thrips
   • Thrips simplex
   • Feeding at the base of emerging leaves produces silvery scarring that later turns brown.
   • Infestation of the flowers produces scarring and distortion.
   • Corms can be corky, sticky when infested with thrips.
   • Store corms at 35-40 degrees for 4 months to kill thrips.
   • Napthalene flakes can be added to the corms in a tight paper bag for storage?

18. Eriophyid Mite Galls
   • Erinea (red felt-like patches) on maple leaves
   • Maple bladder galls
   • Ash flower galls

19. Iris Borers
   • Macronucutua onusta
   • ‘Water logged leaves’ are a typical sign. Larvae feed at the base of leaves and hollow out the rhizomes. Wound areas are frequently colonized by rots and the plants may be killed
   • Larvae are pale pink with a distinct brown head; adults are dull brown moths

Square-Foot Gardening

Charlie Butter has been working with square-foot gardening in his yard for the last few years and has seen some impressive results.
• The square-foot gardening technique is based upon the book by Mel Bartholomew by that name first published in 1981.
• Use a square foot system to make the most use of your garden space allowing you to raise only the amount of food you really need and will eat.
• 1 square foot = 4 lettuce plants, 1 pepper, 9 spinach or bean plants, 16 carrots or onions or radishes.
• Defines boundaries so that you take care of the plants you do have – less work, carefully grown plants – higher production.
• Vine crops are grown vertically to take advantage of smaller spaces.
