Why do my cauliflower heads seperate. Is this do do with nutrient or is there another cause. Happens all the time with me and I feel like giving up on them, ??

I am a little unsure but it may be two possible scenarios one masking the other. Firstly, It may be a Boron deficientcy, this micro nutrient required in minute quantities, over use is a really problem make sure if you use only apply up to the recommended quantity and NO MORE. Secondly Low nitrogen levels inconjuction with heat in a micro situation. Please let me know how things progress for you. Seasol may help?

Will have to wait till next year as its to late to go again now. thanks for the advice boron might be the answer as I have tried most things.seasol and other nutrient providers.

Put Fruitfly mesh over plants from day 1. Prevent all insect contact.

just wondering if anybody has good tips for natural and organic pest control.seem to have a lot of aphids and white moths. plants are nice and healthy apart from leaves being eaten

I use just plain flour, sifted onto the leaves of my plants, it acts as a stomach poison on the caterpillars but doesn't harm anything else, no harm to you and breaks down quickly

If you steam the cauliflower to slightly underdone (about 10-12min) Pulse shred it in a processor to a rice consistancy. Serve with a sauce... My kids did not even realize what they were eating...they hat veggies, love rice. It is also an excellent idea for dieters.

Hi Cauli-Community, Here on the Sunshine Coast QLD have problems with white butterflies and worms eating away the leaves. A decent daily spray of garlic and chilly infused water seems to fight off both successfully. Caulis seem to be strong feeders; I applied good general fertilizer weekly and added aged cow manure a shovel load per plant per month. Heads are now developing, yeah! I grow them under 90% shade cloth and hope this keeps the heads white. temperatures are going up which they dont seem to like a lot; supply decent deep root drinks daily. Fingers crossed! Joe
