Dealing with Pests & Diseases

The following tips & tricks are for guidance only and should be used with care. Some of them I have tried, some I have not.

Tips I have actually used & are effective are marked with  *

Dealing with Aphids

  • Plant Egg Plants, Tagetes, Calendula to encourage Hoverflies, which will eat Aphids. *
  • Encourage Ladybirds & Lacewings onto your plot, they too eat Aphids. * 
  • Plant Tobacco Plants, Whitefly will stick to their sticky surfaces.
  • Spray your plants with soapy water (1 teaspoon of washing up liquid to approx 2 litres of water). * 
  • Attract birds, many of them eat Aphids. *
  • Wash Aphids off plants with jets of water, or rub them out by hand. *
  • Douse a rag with vegetable oil & smear Runnerbean supports (and other supports too) with the oil. Aphids will stick to it especially Blackflies. The vegetable oil will also help to preserve garden canes/wooden stakes. *
  • To keep aphids and other pests off your roses: Finely chop 1 onion, 2 medium cloves of garlic.
    Put ingredients into a blender with 2 cups of water and blend. Strain out the pulp. Pour the liquid into spray bottle. Spray a fine mist onto rose bushes, coating both tops and bottoms of leaves

Dealing with Slugs & Snails

  • Use barriers, but remember some slugs live underground. *
  • Grit, woodash, soot, sawdust can be spread around plants but these may need replacing after rain or watering & there must be no gaps left. * 
  • Copper tape or old unpainted copper pipes will shock slugs & snails. * 
  • Beer traps are effective, use small pots with beer/lager in, bury the pots up to their rims around your garden or plot. Use small plastic bottles, cut the bottle off about 150mm  from the top, reverse the cut off piece & slot it into the body of the bottle, this will stop any sober slugs getting back out? * 
  • Nematodes can be used, these are microscopic parasites. The powders can be purchased, mixed with water & watered onto your soil to kill slugs above & below ground.
  • Encourage birds, Frogs, Toads & Hedgehogs into yor garden or plot. All these are natural predators of slugs & snails. * 
  • Keep your garden/plot tidy. Remove items that slugs or snails can hide under. Look for slugs/snails at night by torchlight you will be surprised how active they are in cooler dark conditions. *
 Dealing with Millipedes (Not Centipedes)
  • Punch old tin cans full of holes and fill them with potato peelings. Then bury the cans in the soil around your garden/plot. Every few days lift the cans & dispose of the Millipedes.  
Dealing with pests & Diseases (Mainly Organically)
  • (Pea & Bean Weevil) Dust your plants with soot or lime, use a nicotine spray but remember nicotine spray will kill most insects.                                                                                              (Halo blight) Spray plants with Bordeaux mixture
  • (Cut worms) Use plant collers or spread a circle of woodash or salt around the base of each plant.
  • (Clubroot) This is a fungal disease attacking the roots/stems of Brassicas, therefor strict crop rotation should be used. Several control methods exist but are not necessarily effective. Liming, Putting a cube of Rhubarb in each planting hole before planting, Achieve a high Ph of 7. If you suspect Clubroot is infecting your plot burn or dispose of all affected plants, do not compost them.
  • (Cabbage root fly) This fly mainly attacks Caulis & Cabbages. Place collars around each plant. Earth up plants.  
  •  (Flea beetle) Spray them off with water or use Pyrethrum dust.
  • (Carrot fly) dress around plants with soot, keep plants covered with fleece or sow seeds inside barrels/containers which are taller than a metre above soil levels. *
  • Add a couple of drops of Olive oil into your water barrels to keep midge away.
  •  Sprinkle Bicarbinate of Soda onto brassicas to eradicate caterpillars/slugs.
  • Make a 50/50 mix of Bicarbinate of Soda & White Flour. Dust the mix over plants affected by Cabbage Worms.

    KILLS ALL INSECT (good ones & bad) 10 Garlic Cloves, 10 small Chillies, 1 tablespoon of vegetable oil, 1 Litre of water, 1 teaspoon of washing up liquid. Blend liquidize & strain. Add to sprayer to use.

  • Natural enemies of moth & caterpillar larvae include, Wasps, Spiders & Tachinid Flies 
  • The following (2) tips are from the 1800's, I have not tried them yet so I am assuming they will dispose of most insects?
    1. Boil your old potato plants well in water (not diseased ones). Strain them off and sprinkle the cold liquid on your veggies.

    2. Steep your old tomato plant LEAVES in water, strain off and use the liquid on your ROSES. Place old tomato plants around the base of fruit trees to see if they deter ants etc.

    Some Insects & The Plants That Repel Them

    Aphids = Anise, Chives, Coriander, Garlic, Petunias, Onions, Radish.
    Ants = Pennyroyal, Peppermint, Sage, Spearmint.
    Grasshoppers = Calendula, Horehound.

The Last Post

As my readers will already know I moved to a new house (bungalow) last year. Much work, updating, d. i. y. and a vast amount of gardening and landscaping needed doing to the property. Most of the gardening to the rear of the property has now been completed just as the Wintery weather begins to take hold. A good sized vegetable plot is one of the features in the back garden prepared and ready to be utilised starting with next Springs sowing and planting. With this in mind I spent a couple of weeks last month tidying up N1 plot before deciding to give it up just over a week ago. Due to the amount of work on the house and gardens this year my blog posts have been just about none existent. Over the past seven years I have enjoyed reading many other allotment/gardening blogs and meeting/talking to lots of other gardeners on the "net". I hope my blog has been of interest and some use too, to all who have spent their time looking in on it. Good luck and best wishes to all you love…

Rooko's April Top 10 Tips & Tryouts

1. Clear away spent flower heads from spring flowering bulbs such as hyacinth & daffs. Don't cut away or discard the foliage as it will replace the bulbs energy for its next flowering.

2. If the weather in your area has been dry enough lately and your soil is not wet and heavy, now is the time for some rotavating/digging, adding compost/manure as required to the soil.

3. Air temperatures are still relatively unpredictable in my neck of the woods at present, it may be worth checking the germination temperatures of various seeds before sowing takes place.

4. Easter weekend was the traditional time for getting your potato tubers into the ground. Don't put them into wet soil and remember Easter weekend is early this year so another couple of weeks wait isn't a problem.

5. More overnight frosts have been happening in this part of the country recently, compared to the past few years. So if you are sowing planting this month keep cloches or other plant protection equipment a…
