_____.

Carrots and Onions planted in alternate rows drive off both the onion or carrot fly.

Sage,
Rosemary and Wormwood planted nearby produce strong smells that repel carrot fly maggots, who attack the roots of carrots.

Sow leeks and carrots in the same row for protection against carrot fly. Then harvest the carrots and leave the leeks to mature for later.

Chamomile (Anthemis nobilis)

Chamomile encourages plants to increase their essential oils and therefore taste and smell more strongly:-
Mint,
Cabbages.

Rather than growing Chamomile as a lawn because of high mowing maintenance, plant Chamaemelum nobile 'Trenegue' which never flowers and never requires to be cut. See Herbal Lawns for other low maintenance grass lawn replacements.

Plant 3 feet away from Onions.

Comfrey (Symphytum asperum)

Bees love it.

Mow leaves every 2 months in the summer and use as a mulch round your vegetables/fruit to provide potassium, nitrogen and phosphates.

Compost Bins

During a trial by the RHS, it was found that shredded prunings which filled a series of different 1 cubic yard domestic garden compost bins only reached 20 degrees centigrade and did not kill the weed seeds or produce good compost. When the 10 cubic metre compost bin was filled, it reached 60 degrees centigrade and produced good compost.

From 17 years of experience on a multitude of client's gardens, I recommend the following:-

• Have a small plastic dustbin under the kitchen sink and fill it with vegetable peelings, tea bags, coffee grounds and fruit but no meat products, milk products or bread. When full, empty the contents onto a weeded area of your flower/vegetable beds and cover with a thin layer of grass mowings to reduce the smell of rotting vegetation and make a smooth cover which turns light brown.
• Prune your shrubs/perennials and put onto the lawn. Use a rotary mower to cut them up and mulch the beds to 4 inches deep ( 1 brick is about 4 inches ) and then cover with a thin layer of grass mowings.
• Apply grass mowings to beds at no more than 0.5 inches deep at a time to prevent the heat generated during the first 2 weeks of aerobic decomposition from harming the plant stems alongside. The grass mulch can be added to every 2 weeks.
• Grass mowings applied as a mulch by themselves or with manure/compost underneath is the only material that on a steep slope will not be washed away by heavy rain.
• Pernicious weeds like ground elder, bindweed, bramble, or couch-grass should have their roots dug out and either donated to the rubbish bin or cut up and used as a mulch in a thick mature hedge or under a stand of Leylindii Trees where the ground is dry and malnourished.

Coriander(Coriandrum sativum)

Anise,

Dill, Chervil and Coriander growing between rows of carrots and cabbage will protect them from pests.

Coriander will wilt when Fennel is planted alongside and prevent fennel from forming seed.
