Brianna's Question

Brianna wants to build a wall of basil for her restaurant:
Hello! I am going to be building a greenwall of basil in my restaurant and have been scouring over your instructions. I have a few questions for you. 1.) For watering the wall, should you have just one tube at the top of the wall or a few tubes running horizontally at different levels? My wall is going to be about 10 ft. tall. 2.) I clicked on the link to "Jungle Walls" and they suggested using a "non-woven polypropylene geotextile fabric", which looks as if it replaces the moisture retention mat. Do you know anything about this material and if it would in fact work? It's much cheaper than the moisture retention mat, so I was just wondering! Thank you so much for your help! I'm really looking forward to putting my greenwall up!

For watering on a 10ft wall one tube across the top should be sufficient. Gravity will do the work. Almost any non-woven synthetic will work. Some fabrics will retain water better than others. You'll need to adjust your watering accordingly to suit your plants. You may want to start with a 2x2 test square before you make your wall. See what works best for basil. That way you aren't losing many plants as you work it out. Good Luck, Matt


  1. I would be a bit careful with using basil plants. The plants look great while they are small (the first 3-4 months) but when they start to bloom the luster wears off. The leaves get smaller and/or fall off and the stems get woody. For the wall to keep its appeal I would expect you to have to rotate the plants continuously - e.g. sow new seeds every few months and weed out old plants. Depending on the wall size it might be a lot of work.

    1. For good looking basil, do not let it blossom. Keep prunning it before blossom.
