just want to know why u have to cover the celery when it grows into stalks what is the reason for it and u stated its a cooler climate then why do they sell in nurseries

It is not so much, cover the stalks but protect the side stalks. Celery is best grown close to each other in rows. This then blocks out the sun from the side stalks. With lots of sunlight the side stalks become very green and bitter. Usually you trim these off the plants when harvesting them. Or protect the sides from the sun and then you can eat these stalks also. It is ridicules what nurseries and Bunnings etc sell in the wrong time of the year. Go to "Seed Collection Pty Ltd" and find their planting guide for Veg, flowers, herbs.

We are going into summer here in the south of australia and my celery plants are starting to bolt? Do you find this happens when things warm up? I thought they liked it warm and moist? Or have I got my seasons mixed up?

depending on the authors knowledge of living for a year in each of the zones... weather has changing attitudes in each. I hope the 3200 elevation in mid california does fine. we are a vegetable growing couple, ready for new adventures. wish us luck

For the past few months, I have been buying celery from our local supermarket. Every celery that I have bought has had its sweet center sticks cut off... not the center core stems and leaves though. I complained to the manager and he called the farmer. The farmer said that they have been cutting the sticks off because they were flowering... That makes no sense to me. Surely the flowers come from the center of the core or on different looking stems... not on the sweet inner leaf stems that we usually eat... please confirm.

What diseases affect celery and what steps can one take to avoid attacks.
15 Apr 17, (Australia - sub-tropical climate)
Celery is susceptible to various fungal diseases which cause the stems to go brown and rot so keep the beds weeded to allow good air circulation. Fungal problems can also be caused by overhead watering and heavy rain. You can't control the rain but ensure celery is planted in an open, sunny spot with good airflow, Good soil and balance in your garden planting to provide food sources for beneficial insects such as ladybirds, hover fly and damsel flies will control aphids, etc that turn up. Any 'daisy' type flowers are good beneficial host plants

My celery has been the biggest hit in my garden all Summer here in Taumarunui. Its starting to look past its best, rip it out now or wait for the frost to get it and continue to use it until then? I was under the impression you could sow celery for winter, this is obviously wrong and I should now wait till spring? :}

In your area you would normally sow seed in march and April in your glass house ready for transplanting in May and June. You could also sow seed in August and September for October and November planting out. To avoid stringiness in your celery keep the water up to the plants. Well manured or composted soil will also help.
