I would like to note that all my efforts in the garden are all organic i do not use artificial fertilisers or any chemical pest or weed control methods

fertilisers i use include:
seasol (seaweed concerntrate)
power feed (liquide compost with fish emulsion)
cow manure
chicken manure
for weed control i use my hands
and pest control i invite predetory insects to control the pests
and if i find a plant that is being attacked by pests i levae it there in the hope that will only attack that plant and leave the others alone.
