Please can anybody help? I have been growing Ipomoea to grow up my 5ft fence the last couple of years and have only just realised they are poisonous. As a couple who are looking at adopting a rescue dog soon, I have had to veto them, obviously.
It’s a shame as they are beautiful climbers, but I’m looking for a replacement climber that I can grow from seed. Something relatively easy. And not poisonous.
The area gets some sun in the morning but turns in to dappled shade, then full shade by the end of the day. The sun goes from left to right when I am facing the back garden, if that helps?
Climbing Nasturtium grow anywhere and you get an added bonus of edible flowers and leaves. If you are planning to grow sweet peas up a north facing wall you will need to either buy plug plants or get the seeds established inside first.
I get something like a 2 litre ice cream tub and put an inch of good quality compost in the bottom. Then stand loo roll middles in it and three quarter fill with compost. Put one or two sweet pea seeds in each one. Once they grow put in a thin cane and support. Once they have reached about 3 inches put the tub outside to harden off and plant in May. Try to warm the soil up with plastic covering or a mulch before you plant them out. I find that sweet peas on a north wall need a lot of help, so I snip of the tendrils and tie them to stakes or trellis. This allows them to put their energy into producing flowers. The more flowers you cut, the more you will get. At the end of the season let them seed so that you have a crop for next year. They won’t necessarily come back to the same colour though.
