All I can say is passiflora does get heavy, and the vine will reach through the fencing onto the other person's yard. Eight pots of passion vines are way too many.

Hi,

Thank you for your reply. There is no one on the other side of the fence, so reaching through it would not be an issue, but the vines will get cut if the HOA attempts maintenance.

How many passion vines container should I use for 5x40 foot fence?

Not an expert, but I would suggests 2-3 vines. Once they get going, you could have vines growing over 10 feet long. If you center the pots, that would give you 10+ feet of vine growing on either side of the pot. Not knowledgeable about how they grow in no. CA, but here in so. CA, they grow pretty fast and my p. Incense is green year around. I have lots of cleanup because the vine will grow over every other plant if I allow it so have to constantly cut/pull the vine away from my other plants. It's good that they will be on a concrete slab because they spread through runners underground and pop up feet away from the original plant.

if you are in the hot part - it will grow fast with plenty of water in the heat - in the cooler parts, i suspect it would be a little slower. I had a vine in Pittsburg that escaped its pot and took over our yard in about 2-5 years. it created a curtain over our deck and travelled under our lawn and up the tree on the other side by the 5th year - also once established i didn't do anything for it in the winter. now hte curtain was maybe 6 ft by 8ft of pure vine. it anchored on the top of the deck and hung - had a bird nest in it for several years. just planted another one a couple weeks ago - now south of SF - its already showing sings of clinging to everything in the vicinity and growing nicely.
