I don't think that should be an issue at all. I planted some sweet peas in a pot that I have an obelisk in and that will house several different clematis.

Nasturtiums are very attractive to black aphids - in fact they are often used as a companion plant in vegetable gardening to draw them away from the veggies. So don't be surprised if the intermingling of the two vines results in the intermingling of the aphids as well.

Hmmmmmmm. I guess I could just put my 2 climbing nasturium on the fencing post's for my 2 tomato patches.

Thanks

Strange Pam as I have grown nasturtiums for quite a few years to put in salads and I have never had aphids on them. Aphids on other plants not even close to the nasturtiums, but never on the nasturtiums. Only shows what I have said time and time again, what works in one garden may or may not work in another and the only real way to know is to give it a try.

All I can say Miguel is that you've been very lucky, as nasturtiums are notorious for attracting this pest :-) In fact, if you do a search on "nasturtiums" in general, virtually every site will remark on this problem to some extent. Maybe it's your climate/location? And you're 100% correct - what works well in one garden may be a total disaster in another!

Check out the photo in this link - that's what nasturtiums look like here in midsummer.......gross!!!!

Here is a link that might be useful: what's that black stuff on my nasturtiums?

Gross is hardly an appropriate description Pam. Yuck!!! Believe me I get aphids on many things, including clematis seedlings that I have started but never the black ones--usually just the green colored ones or orange colored ones back when I grew the tropical milkweed ascelpsias curassavica. Don't know what it is, but knock wood, they have never been on the nasturtiums. Let's just hope this doesn't jinx me this year! LOL

wow, I've never had any bug on any nasturtium, ever - at any garden or location.

I had no idea they got bugs.

The only mildew I've ever had was on some short zinnia, and that was our fault as we watered late at night and it didn't have a chance to dry properly.
