Soak over night - up to 12 hours then plant.

I have been told that SCARLET RUNNER beans, will usually fail to flower and fruit in my sub-tropical Brisbane location, presumably owing to temperatures and humidity. If this is correct for usual planting times, so should I try growing them in our Autumn and Winter period ?

There are times of the year to plant a crop and times when not to. I don't plant beans in the autumn/winter - why because the bean fly kills them. Late summer autumn is usually a wet time with rain - rain is the giver of life to most things, plants insects disease. So now I grow my beans from late winter - no bean fly no problems. In sub tropical don't expect to grow much over summer - weather extremes are too hazardous for most plants. I live near Bundy.

I have given up on Scarlet Runners, had no success in Brisbane, some success in Southern NSW and good crop in Canberra. That should indicate the weather they like :-) I now grow dwarf beans only, fewer pests, bigger crops, no need for frames or teepees.

Can you start pole beans inside instead of outside. My ground not ready yet

You have to be very careful growing seedlings indoors. New seedlings chase the sunlight and become very long (leggy) and thin stalked and therefore weak. Easy to snap the stalk. I germinate seed under shade cloth part day in sun, part day in shade. Two days after germination I take the shade cloth off. I move the table to vary the hours of sunlight and shade depending on how small/big seedlings are and what the temperature is.

I have some Purple King, first time with these, and they are climbing up the frame very well. I had a suggestion to pinch of the top to encourage them to spread sideways. Is this a good idea? If they keep going, now over 2 m high, I will have to train the leaders dideways or down as they will have run out of support. Cheers.

I have done two plantings of climbing beans recently, 1st crop has just finished and 2nd crop I'm picking now. I have trellises 2.4m long and wire mess 2m high. I plant seeds about 15-20cm apart. Didn't take them long to grow 2m tall. Mine just flapped in the wind and then started growing down the trellis. I'm picking 1kg each 2-3 days. So I don't think you need to pinch or train them sideways etc.

I have seed packets of scarlet runner beans and wish to know if I can plant them now, August. It is hot: 87-90 degrees Fahrenheit. But cooling into Sept, and lovely, mid 80’s. Also we are fairly close to the ocean (Fernandina Beach) on 4th dune ridge, but have potting mix and Black Cow. Citrus and basil grow great in our yard. Have a spot there gets mostly full sun. Also my Purple Hyacinth, planted in June were doing great until the husband put weed killer on them and some lilies. Will they come back, or must I replant seeds? This is a first for me. Thank you!

It depends how cold your winters are; if you've had frost and temps are dropping below 15 degrees at night, it's currently too cold to be growing green beans with great success. I've only grown broad beans in the past and they were quite tolerant of temps into the low 30s, so provided your Spring doesn't heat up too quickly you're probably best waiting until late August or even September. Again, really depends on the nightly lows. Also beware that Seasol is merely a tonic, not a fertiliser (it doesn't have the nutrients in appreciable quantities to make a difference). The same company makes a comprehensive liquid fertiliser called 'Powerfeed' which, combined with Seasol, has worked wonders for my container chillies in the past (the standard version isn't certified organic but there is a certified organic version available now, albeit much diluted compared to the standard version). Depending on how many nutrients are left over from the manure, the lack of regular fertiliser may also be the problem - so I'd try something like Powerfeed or Searles 5-in-1 liquid fertiliser in addition to the Seasol (every week or two). Best of luck
