I'm in Melbourne now but moving to Philipnes soon and it's mostly hot and humid there. I'd like to know can I grow celeriac when I get get there. The soil is mostly well draining sandy

I thought I planted celeriac at the right time - May, but now Sept & no bulbs. It's been nice & damp, good drainage with compost pre-dug in, planted in full sun, but cool thru winter. They look like they've had to much nitrogen though I haven't used it. If I added potassium now, how long could I/should I leave them?

If the plants have survived, then leave them as is - they should hopefully start to swell up into bulbs and give you harvestable produce by december/january

Masters, at least in Dandenong South Cnr St Gippsland Freeway & Princes Hwy, VIC we bought seedlings. It is funy that when I went now to search on line I could not find it

generally, lots of leaf but no bulb would mean too much nitrogen and not enough potassium. Nitrogen is used for leaf and stem growth, K is essential for fruit and flower formation. grow in soil that has had hungry plants like leafy greens of broccoli grown in it previously, and avoid high nitrogen manures, use well matured compost instead. The parent crops of modern cultivars of celery and celeriac grew in marshes, so make sure soil is deep and moisture holding. All through summer, it will be just leaves but the bulb will swell suddenly in a burst of metabolic resource direction in autumn/ early winter, in order to give itself food stores for the cold season. If temperatures are cool in your winter, you can leave in the ground unitl you need to harvest them.

I have been growing celery in my garden for the last 8 months, I decided to pull a few of them out and the bulbs on them were huge!! Is this also celeriac ?

Can you eat celeriac leafy stems

Hi Bob, yes you can, chopped up in soup gives a great flavour, but not so nice, too strong, for salads....cheers

I found Celeriac great to eat when grated into a green salad and also coldslaw. with a French or Italian dressing.
