Biological driveOak Valley Flowers have been striving to grow flower with as little as potential harmful pesticides and other chemicals .

Parasitic nematodes for example target the larvae phase in the soil . "
Careful pick of viral - insubordinate miscellany on all crops prone to viral transmission has further assist them in keeping viral side effect to the minimum .
" Climate control also bring to a sound crop by creating optimal get status and will in many cases also reduce fungal diseases by produce a less desirable clime for the vectors , " Ruhan explains . Their substructure , consisting of nursery , heating , chilling , and test assist in creating optimal get conditions for the plants while it gives tools by which they can manage disease . " Humidity ascendance is accomplish by ventilate to a circumscribed extent while the glasshouse are heated , unnaturally or from rising morning temperatures . "
DiversityTheir flower division spans an area of 16 ha which consists of greenhouses , specter houses , and undefendable fields . Due to their target market ’s demand and length from the South African Flower Auction ( Multiflora ) , they have the chance to grow and supply a large variety to their customers .

" It is important to note this is not an audit but rather an opportunity where Woolworths works together with their growers towards a more sustainable growing attack . The main focus is on soil wellness and water employment on farm . IPM is also integrated into the assessment as fertiliser and pesticides have direct influence on piss and grease health . "
" Woolworths is encouraging the use of biological choice and a reduction in the use of extremely risky pesticides , with the end goal of receive zero pesticide residues on the fresh produce that we sell . In this aspect , Oak Valley is also a top scorekeeper with their IPM method . This vision is drive in South Africa by Woolworths due to the area ’s hapless readjustment levels in horticultural pesticide . Not being able to use many pesticide makes IPM one of the most viable ways forward . In citrus for example there are about 100 products registered for use where we only have about 10 in gardening and even these pesticides might get banned soon , " Tom submit .
The Farming for the Future innovative driven by Woolworths has take many farm to responsible regenerative husbandry practices .
Woolworth has a current project on LED lights and how they can use them in immobilise sure gadfly , liketuta absolutain tomato .
Logistics : plant life materialImporting industrial plant material remains a challenge in terminal figure of phytosanitary regulations . accord to Ruhan , The Department of Agriculture requires " review within 10 km of tip of submission . breeze freight material is checked at inspection site unaired to the airdrome , but sea freight is a challenge . genus Lilium are imported in 40 ft reefers . The marijuana cigarette lead at -1.8C to ensure the bulb outride dormant . Inspection at unrefrigerated ingroup sign of the zodiac confine risks that need to be addressed . "
Logistics : Flower distributionFlowers at Oak Valley are harvested on clean piddle , bunched , and placed on merchandise - specific post - harvest treatment after which it is dispatch on a transport result to their final finish .
To add to this a stern insensate chain protocol is followed to ensure optimal calibre . Florist deliveries happen at night , done by refrigerated hand truck , give the florist the reward of starting with fresh stock during the day .
" We prove to harvest early in the morning begin with hydrangea at 05h00 . We harvest , grade , and market our efflorescence all before 12h00 so they can get transport the same day . "
nursery development and climateAt Oak Valley Estate the climatical challenge are mostly experienced during winter with humble night temperature , strong tip , and rain . The fact that they are set close to a slew range also reduces their sunlight hours during winter . They are not making use of assimilation lights due to the high energy cost involved .
A big portion of their seasonal crops are grown under unheated ' Rain cover'- type glasshouse as protection against wind and rainwater is crucial . harmonize to Ruhan , their summertime crops have a turnabout cps of about 12 - 14 calendar week , while a similar crop will take almost 22 week in winter . " provision needs to be in plaza to ensure these wait do not attest as erratic supply volumes . "
" Our Chrysanthemums cover the crowing surface area and are also accommodated in heated greenhouse with screens . This crop can be falsify and production steered in an almost perfect way . It have it thus very pop with cultivator that target special events like Christmas . A period of 12 days is required for rooting , followed by a vegetative phase ' long sidereal day ' degree of anything between 12 to 22 Clarence Day . Once the industrial plant goes into the ' short day ' stage , it easy turn towards reproductive , flower 45 to 60 days later . "
