Hi, I planted seeds in December, but although the plant continues to grow, to date, I have not had any flowers? I have previously grown them in the same vicinity very successfully. Any ideas will be gratefully accepted. Thanks

If the soil is very rich they would probably produce a lot of growth before flowering. I had climbing beans in a new rich garden bed and they grew to about 1.2-1.5m before flowering. Plants would have gone to 3m if the trellis went that high.

We bought a packet of bean seeds about 6 years ago from M10. Unfortunately we lost the packet and can't identify the name of the bean. Can anyone help. The seed is black when you plant it. The beans are a climbing bean. Very flat and Matt (not shiny). They are the BEST tasting bean and produce prolifically. We save the seed annually, but would love to know what they are. Please!

Go to a seed selling website and look through the beans seeds they sell, you will probably find what you grew. Try Boondie Seeds or Eden Seeds.

Hi www.koanga.org.nz have a black runner bean seed called Takamatua. Check the photo on their site. Great range of NZ heritage seeds on this site.

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!

The planting guide says that you can plant them now. Plant and give a good watering and don't water for 3-5 days. Too much watering in hot weather will rot the seeds.

Short pods on healthy plants could be caused by poor pollination due to heat. Beans are a warm season crop but pollination and bean set on climbers like Scarlet Runner can be reduced on very hot days. I have seen Scarlet Runner with some good pods then a gap on the flower spike where the beans didn't set pods then more pods. Beans are self pollinating and don't set on very hot days. I presume the plants are growing from a root that has been in the ground for a number of seasons. As you suggest, regularly picking is a must to stop beans going tough. Cutting back the tops of the runners will reduce your harvest in the short term but will encourage denser growth and may make the plants more manageable. I trust this helps. Maybe another reader has some ideas to solve your problem.
