Earwig Control

Earwigs damage vegetable seedlings, AND they enjoy eating your apricots, blackberries, raspberries, stone fruits, strawberries, dahlias, marigolds and zinnias,  just earwingto name a few!

Earwigs are busiest during June, July and August and there are several organic options to control earwigs in your garden.

  •  First remove the objects earwigs seek out for hiding places, this includes stacks of wood, piles of weeds, grass clippings and other plant debris.
  • Pull mulches at least six inches away from tender plant stems.
  • Earwigs love damp conditions, so water your garden and lawn only when necessary.
  • Turn off as many outdoor lights as possible after dark, earwigs are attracted to light.20160917_113819

Trapping Earwigs with Bait :  Poke several ¼-inch holes in the top of the lid of a small disposable plastic container to make a trap. Place your bait mixture of choice inside the trap, then snap on the lid. Bury the trap in the garden leaving about ¼ inch above the soil.  Empty the trap oil_soysauceinto a bucket of soapy water in the morning.  Repeat every two or three days.

Soy Sauce Bait –  Out of beer, then place ½ inch of soy sauce inside then add a few drops of vegetable oil on top.

Beer Bait –  Pour about ½ inch of stale beer into the trap.

Yeast Bait – Use 1 cup of water, 1 tsp sugar, 1 tsp flour, ½ dry yeast, and a few drops of oil – Leave the lid off this trap.  This mixture will attract slugs, snails and earwigs.

Traps without Bait:

Newspaper Traps – Roll a section of newspaper into a narrow tube with a ½- to one-inch diameter. Dip it into water to dampen it, but remove quickly. Set the trap in a shady spot near the garden in the morning.  Earwigs will use it to escape the afternoon heat.  Dump newspaper with the bugs into a bucket of soapy water before they come out to feed at dusk.

Milk Carton Trap–  Wash milk carton well with soap and warm water. Cut off one panel of the empty milk carton, wad some dampen newspaper loosely in the carton. Set the trap near the garden but put it in the shade. Earwigs will hideout  in the wet newspaper to escape the heat of the day. Empty bugs into a bucket of soapy water before nightfall.

Natural Predators: Plant flowers that attract earwig predators such as Tachinid and Digonichaeta setipennis flies.  By adding a border of cosmos, dill, or fennel around your garden you provide a habitat for these insect predators.  You can also encourage other natural predators, like toads or lizards to live in your garden.  And, chickens eat earwigs, too.

DIY: Weed Killer

The Jackson County Master Gardeners’ recipe for making your own vinegar based weed killer:

  • 1 gallon 10 per cent vinegar
  • 1 cup of salt
  • 2 tsp Dawn dish soap or vegetable oil (to make it adhere to the plant)

Growing & Showing Ferns

BACKGROUND
Ferns are plants that do not produce seeds. They reproduce by spores. They are made of fronds (leaves), which unfurl from fiddleheads. The dominant use of ferns is for interesting foliage in the garden and in the house. Some of the more common indoor ferns are: Mother, Maidenhair, Bird’s Nest, Boston, and Staghorn. While the more common outdoor ferns are: Sword, Painted Lady, Ostrich, Rabbit’s Foot and Tree Fern. The Boston fern is actually an outside fern and suffers from insufficient light when brought inside for the winter. There are also seed plants that are called ferns like, asparagus fern, sweet fern, and air fern.

GROWING INDOOR FERNS
Optimum temperature is 65-75F.
Plants will tolerate cooler temps, but most are frost sensitive.
Provide several hours of strong filtered light, by not direct sunlight; it will burn the foliage.
To get even growth rotate plants a ¼ turn every few weeks.
Most ferns like an acidic soil high in organic matter, but Maidenhair ferns prefer an alkaline soil.
Good drainage is imperative. A non-porous pot is preferable to a clay pot. Wire baskets lined with coir are also common. Most ferns are shallow rooted and do not need a deep pot. Ferns flourish in a humid environment, so it is important to increase the humidity around the plant by misting, or sitting the pot on pebbles in a saucer which holds water. Water the soil so that is stays moist, but not dripping wet. Frond yellowing is caused by too much water, and wilting is from lack of water.

Since lush foliage is the goal, use a fertilizer high in nitrogen, but feed at half strength, as too much nitrogen causes root burn in many ferns. Feed once a month.
Ferns never stop growing, but they need a rest period. In the winter when the light is minimal, slowly decrease watering, and feeding schedule, let the fern dry somewhat between watering and stop fertilizing.

To Divide a Fern: Remove from the pot, shake potting soil from roots, and cut the root-ball or rhizome into pieces, each having a frond or two, then plant in small pots. Place pot in a plastic bag, keep the soil moist and keep in a warm shady location. After a month or so, uncover young fern gradually and water very sparingly over the next 3 or four weeks. This gives it time to become accustomed to a less humid atmosphere, or an open room.

Ferns are susceptible to the common indoor insect pests . Using pesticides is generally not advised for most ferns. The best solution is prevention. Use a sterile potting soil.

GROWING OUTDOOR FERNS
There are evergreen ferns like the sword fern, and deciduous ferns. Do not cut back dead foliage until after the new growth has emerged. The dead foliage protects the new shoots.

SHOWING and JUDGING
Show as cut or container grown foliage plants.
Remove dead leaves and exposed roots, Rhizomes should be unbroken. Cut fronds can be placed in a plastic bag to maintain a humid environment. It is best to experiment with conditioning beforehand.
Fronds should be bilaterally symmetrical down the rachis and the pinnae (leaflets) should be filled in uniformly, with no gaps.

Container grown plants (Boston fern, Bird’s nest) should have radial symmetry. New growth is beneficial. The plant should be centered in the pot and and should evenly fill the pot without being over crowded.
Spores indicate full maturity but need not be present to have a frond to be at the peak of perfection. Spores should not be dried or shedding.
