My silverbeet has gone to seed very young they are only six weeks old

A plants purpose is to grow and set seed so that it can reproduce it's self in the future. If there is a lack of nutrient (fertiliser) and or water then it won't grow much and will go to seed. A local farmer has just redesigned his farm (moved soil and laser levelled etc). He planted a cover crop to put some fibre back into the soil. He is watering the hell out of it but it just won't grow much - reason - there is no nutrient in the soil.

Probably one or both of two reasons. They lacked fertiliser/watering or the season, coming into hot summer weather. More a cool weather crop I think.

Our silverbeet has white coating on leaves which is very tedious to wash off. What is it and is it harmful to ingest?

Sounds like powdery mildew, research it on the internet.

A lot of fruit trees take 3 to 5 years to start bearing fruit. Some may take a few years after its first fruiting for it to be tasty. Persist with it and it should be ok.

I planted my silverbeet a couple of months ago,I started picking it the leaves and stalks were great but now the leaves are turning brown the centre of the plant is also brown and the leaves are 'narrowing'. What disease have I got and can I replant in the same spot if so what should I use to clean the soil to prevent a recurrence. Many thanks

Hi All, Just wondering, i have had silverbeet growing in a raised garden bed for about 5 months, but it doesn't seem to grow taller than 5 inches and a few small leaves at a time. Hardly enough to eat. It gets sun most of the day, watered daily and seasol every few weeks. Any advice on how to make it grow better would be great. Thanks Michael

Seasol has virtually no NPK in it. Sounds like your soil is very poor. My tip - reap it out. Start preparing your garden bed for planting in March. Put compost manure even grass clippings in the soil now. Water it and turn it over each week. If it doesn't rain keep watering it 1-2 times a week. When you have good crumble soil you can plant. Or go and buy some fertiliser. I would plant March to about June. Grow it in the winter.

Don't put fresh manure into soil where you are going to plant soon. It needs to breakdown first.
