common mistakes:
over watering
water only when the soil is dry.
this encourages vegetables to develop a deeper root system.

water each type of vegetable based on its individual needs, using a hose and nozzle or watering can.

overheadsprinklers or automatic irrigation deliver the same amopunt of water to everything, which can be too much for some and not enough for others

Over fertilising or under-fertilising

over-fertilising producers soft, sappy growth and flavourless fruit.

if soil is enriched with good quality compost before planting most vegetables will not need fertilizer during the growing season.

this however does not apply long seasons crops like tomatoes, chillies, brinjals and squashes.

they need supplementary fertilzer or a dressingf of compost especially in poor or medium soil.

Not understanding the importance of the soil.

 Even if the main focus is on producing edibles, building up the quality of the soil by applying compost and green manures and practicing crop rotations producers a more sustainable vegetable garden that is still productive.

be concious of the soil at all times 

moderation is the key. incorporate horse or cattle manure occassionaly to introduce differnt types of bacteria ino the soil.

Not thinning out:

This weekens the whole crop becasue of the extra competition for water nutrients space and light.

Over reacting to pests and disease:

Pests and disease indicate a plant under stress.

before reaching for the sprays try to find out the cause of the stress.

Check watering feeding and the amount of sun and make note so taht next year the problem can be avoided.

then go to the garden centre and seek a short term remedy.
