Feeds, Weeds, Pests & Disease 

Sound advice from Glendoick's Kenneth Cox

Feeding your plants

You can use most fertilisers for a wide range of plants.

Liquid feeds are useful as you can add them to a watering can. So ideal for containers. hanging baskets are best with slow release granules which will feed all season. Fruit, veg, trees and shrubs are best fed with granular fertiliser.

 

Organic (seeweed, bone meal, blood, fish & bone etc) and non organic feeds do the same job. may organic feeds are made from waste from meat production. 

Inorganic feeds such as growmore are made using a chemical process. 

  • Compound fertilizers have a mixture of the three most important major feed elements; nitrogen, phosphorus and potassium. NPK on gthe packet. Examples include Growmore and Miracle Gro.
  • Straights are single substance fertilizers such as Sulphate of iron, Sulphate of Ammonia or Epsom Salts. 
  • Organic Fertilisers include Fish, Blood & Bone, Bone Meal and seaweed based liquid feeds.
  • Controlled release fertilizers are useful for containers, pots and hanging baskets as they release the fertilizer for 3-6 months 
  • Levington's Tomorite is high in potassium and many gardeners use it on all fruit and most vegetable crops. 

If you're not sure on what fertilizer to use there is always plenty of advice from our staff.

Weeds

Roundup/Tumbleweed/Glyphosate.

The list of weedkillers available to amateurs is restricted this days. Most products contain roundup/glyphosate which kills everything it is sprayed onto so you need to be careful not to touch plants you want to keep. Back on the market is the Roundup touch weeder which operates a bit like one of those anti-perspirants where you push up the gel from the bottom and then wipe or spear it on the weeks. Excellent for killing brambles when they are tangled up in plants you want to keep. It takes up to a week to see the effect and it works best when plants are in full growth. We have several different versions of this chemical at Glendoick:

 

  • Concentrate: mix up in a sprayer. This is the most economical way to buy it, through it may seem expensive for a small bottle
  • Ready to Use (RTU)  ready mixed, with a handle or trigger. Easy and ideal for small areas
  • Gel  The Roundup Touch Weeder.


From Ken Cox's book Fruit and Vegetables in Scotland

Weeds  

Prevention is better than cure as 1m2 of ground can contain up to 100,000 weed seeds. Perennial weeds such as ground elder, bindweed and brambles are a nightmare to remove in a plot full of plants, so it is far better to get rid of them before you start. The key is to kill or dig out the roots. If you don’t, they’ll simply re-sprout.

Organic gardeners use old carpets and black polythene to cover weedy beds for long periods to starve perennial weeds of light and water. Sadly the worst perennial weeds can survive such treatment. Most chemical weedkillers are not longer available to amateur gardeners leaving roundup/glyphosate as the main weapon against perennial weeds. It  only works when plants are in active growth, so apply from March/April-October. It is neutralised in the soil soon after it is applied so you can safely sow as soon as the weeds have died back and you have removed them. You can use it amongst existing plants but make sure you keep the spray off plants you want to keep. Cover them to be on the safe side. You may need to spray two or three times to get rid of the deepest rooted and most persistent weeds such as ground elder (Aegopodium podagraria), creeping buttercup (Ranunculus repens) and creeping thistle, which can spread underground. Painting glyphosate gell (Roundup) onto foliage is excellent for brambles and other weeds amongst plants you wish to keep. Mare’s tail (Esquisiteum) can survive almost anything, and is perhaps the hardest weed of all to get rid of. It needs to be smashed and painted several times with neat glyophosate and even then it may bounce back. It can break concrete.

Roundup gel is really useful for killing weeds like brambles which are established in a border with plants you want to keep. Just dab the gel on the plants you want to kill.

Annual weeds are easy to hoe or pull out but they can come up in their thousands so you have to catch them before they bloom. I am amazed to see allotment holders tolerating abandoned weed-filled plots with weed seeds blowing all over the place. Some of our worst weeds include thistles, bittercress, groundsel and chickweed, all of which flower and seed fast. Don’t let this happen!

One you have a clean bed and are sowing and planting, a hoe is invaluable. Best used in dry weather. Using it well takes a fair bit of practice - don’t drag too much soil off and don’t slice up your delicate young produce. Mulching and growing green manures are other useful ways of reducing patches of bare earth and therefore keeping weeds to a minimum.

EIQ listed below    Higher numbers are potentially more harmful to the environment, lower numbers are the safest.

Weedkillers

 

Glyphosate (Roundup) (EIQ 15.3)

Non organic

Annual and perennial weeds. Systemic, killing anything in active growth which it touches. Neutralises in the soil. Rain fast in a few hours

Diquat (Weedol)

(EIQ  39)

Non organic

Grasses and annual weeds. Can be used between vegetable rows and for cleaning a bed before sowing. You can sow as soon as weeds die back. Protect anything you wish to keep. Rain fast in 15 minutes.

Acetic acid (vinegar) (EIQ 5-10)

organic

Annual weeds, but tend not to kill roots. Household vinegar tends to be too dilute. You need 15-25% acetic acid solution for best results.

Fatty Acids/Pelargonic acid (EIQ 5-10)

organic

Annual weeds. Very safe to use.


Pests and Disease

Most years our gardens are affected by pests and disease: warm dry weather brings out aphids in huge numbers while wet weather brings slugs, mildews and moulds.

Disease: rust, mildew, etc

Most plants can suffer from pests and diseases from time to time. Mild attacks can just be ignored. Stress: too much moisture, drought, or starvation can make plants more susceptible to problems. To much fertiliser can produce soft, leafy growth that is more prone to attack for example.

 

For insect pests and pigeons on vegetables, horticultural fleece suspended on a frame or with cloches, is the most effective prevention. Try to ensure that the edges of the fleece are buried in the soil at the sides, but remember to loosen it as plants grow. As chemicals for carrot fly and cabbage rootfly have been banned, this is the only way to keep them off.

Control varies from problem to problem, but identifying a problem quickly and dealing with it immediately will prevent the problem getting out of control. Crop rotation, for instance, helps prevent the build-up of soil-borne pests and diseases.


Slugs

Some Slimy Facts: One individual grey field slug can produce 90,000 grandchildren; a cubic metre of garden will contain on average up to 200 slugs; it is estimated that slugs consume twice their own body weight every day; a slug weighing 0.1oz would, over a 20-week growing season, consume an astonishing and expensive 1.75lbs of plants and vegetables each.

‘Beechgrove Factsheet’, 2004, no 4

Slug killers: the choices From Fruit and Vegetables in Scotland

  • Ferric phosphate (or) – EIQ 5   this is a safe chemical method which is effective
  • Metaldehyde – EIQ 11   the liquid form is safest as it cant be eaten by pets or birds.
  • Barrier, such as wood ash, crushed Aluminium sulphate (or), 5 eggshell or sawdust, or traps, such as a dish of beer. 
  • Start vegetables early and keep them dry to deter slugs.
  • Minimise hiding places by keeping garden tidy.
  • Deterrent plants are said to be mint, chives,geraniums and fennel.
  • Oat bran for them to eat apparently makes them bloat and die.
  • Parasitic slug-destroying nematodes 

(or = organic. EIQ rating – the higher the number, the more potentially harmful or dangerous is the substance.


Rabbits, Deer and Other Mammals

With very good reason, Scottish gardeners everywhere bemoan the attentions of rabbit and deer, two out-of-control pests. You can be as sentimental as you like about fluffy bunnies, but they can destroy your vegetable patch. You need to decide which of the two you are more attached to as co-existence is not an option. Fluffy bunny websites tell you that you can keep rabbits off with chilli powder and other home-made remedies. Don’t believe a word of it. One useful rabbit repelling product is a calcium solution marketed as Grazers which you can paint on foliage. The vegetables taste horrible for rabbits, pigeons and deer but apparently humans [img>don’t notice so you can spray right up to harvesting.

For long term peace of mind, bite the bullet and agree that rabbits need to be fenced out or killed. Fences need to be part buried in the ground 20-30cm and even then rabbits may dig underneath. For rabbits the fence needs to have a mesh of 2.5cm diameter and a height of 1m-1.2m. Deer are most likely to damage plants in winter, when they are most hungry.  Barking of fruit trees can be fatal so individual tree guards are a good precaution. Roe deer can leap a 2m high fence, so it is an expensive business keeping them out. Grey squirrels in urban gardens, rats, mice and voles can also be a serious problem when they discover and eat your growing or stored crops before you do. Mice are particularly fond of eating newly planted seeds such as peas and beans. 

Pigeons

Netting is essential to protect Brassicas (cabbages, sprouts etc) from pigeons. If you dont protect them you will find them stripped.

Covering plants with horticultural fleece (before the pests attack) will prevent some insect pests and birds reaching the plants. It's important to ensure the edges of the fleece are buried in the soil to prevent access and that the fleece is loosely held over the plants so that it can move with them as they grow. This is how many growers produce carrot fly-free carrots and cabbage rootfly-free brassicas.
