Can rhubarb be grown in sandy soils, in beachside suburbs?.

What happens to the plant if you only harvest the real big stalks on the bush in the first year?I have a bush that has very healthy and large stems in the centre of the bush.

That should be fine Ian. The main idea is to keep enough foliage on the plant so as to keep up good continuous growth. Taking the odd big stem now and then should not effect this.

I am leaving for the winter(live coastal Tassie). Do I need to do anything to my healthy rhubarb before I leave later this month?

This morning I found all the stema of one plant limp and lying on the soil and the leaves, were discoloured and looking sick. I have 2 other crowns in the same area and despite applying liquid fertilisers and solid manures they have not produced any significant growth. There is a fig tree about 2 metre away.

I have 6 plants in a very similar condition & treated them similarly to you. They used to grow quite strongly in the past. I have today dug them up to plant in another part of the garden. This will be just trial & error at this stage. Will be interesting to see if it makes any difference. One thing I did find when digging the area was 4 curl grubs, but I don't think there were enough to cause the problem?

"Be sure to mix compost, rotted manure, or anything high in organic matter in the soil. Rhubarb plants are heavy feeders and need this organic matter. Don't add a chemical fertilizer when planting rhubarb or during the first year of growth. Direct contact with nitrates can kill your rhubarb plants." (source: almanac.com/plant/rhubarb)

When should I harvest the crop? The stalks have remained green , are they safe to eat?
