Look for aphids. If the leaves become mottled with rust coloured spots it's probably bacterial blight.

Some of my celery stalks are a bit hollow, anyone know what causes this?

usually it means a lack of continuous access to water

Celery is a traditionally cool weather crop (if you are after the long white crunchy stems) but they do have a high demand for regular watering and fertilizing.. If they are grown too slowly the stems become bitter (which is what I think you are meaning by salty). If you want crunchy, sweet stems you do need to keep up the water and nutrients (complete type but high in nitrogen and potash). You can also grow them right thru the warmer months if you ratoon the plants when you harvest. i.e. cut off all the leaves and use them however you like. The plants will re-grow but remember to keep up the water and nutrients. I have grown celery for leave (not the stems ) right thru a warm summer and ratooned them 3-4 times with no problems. You will find you won’t get the long crunchy stems in the warmer periods but the small crunchy stems and sweet leaves are still great in cooking. So in answer to your question, along as they are growing well and the leaves/stems are sweet, then keep eating them. Cheers John.

Now I am really confused. One comment says celery is really a cool climate veg,and I have just harvested mine. But above it is telling us to plant now meaning that it is growing over the heat of summer! I would love some more info about wrapping the celery, timing etc. I am aiming at getting crunchy green sweet stalks ( like in the shops) for juicing. All ideas appreciated.

Check what zone people are commenting on in regard to planting. In the temperate zone we generally grow from Feb to Oct for most veggies. The cooler months. In the south they might grow stuff in the summer.

I need help on how to grow corn, everytime i plant seeds they always seem to shoot up then die a few days later. What am i doing wrong ?

I have more luck starting them off in seed trays then transplant when 10cms high.

Celery take a long time to grow. After 2 months my seedlings were like 3 week old lettuce. I don't know your climate but we grow them autumn into winter. I will finish picking mine this week (last week of winter- Australia- sob-tropical climate). Maybe a bit of fertiliser to kick them along. They need sunlight. Hope they are in a decent size pot, have a big root system.
