Do you think the copper would work with black millipedes? (Or do you reckon with all their little legs there would be insufficient deterant?)

I planted basil last year and something ate it all leaving just the stems. It was there one day and gone the next! I don't want the same thing to happen again, but I couldn't work out what ate it. Nothing else in my garden bed was touched. Does anyone have any ideas of what may have eaten my basil?

I have the same problem with possums. This year I am going to try growing it in a cage.

It could be various things however id suggest something clearly visible if it can devour your entire plant overnight caterpillars and snails are the usual suspects

It is normal, we just lost one. Staff of buntings told us have to wait for at least six weeks before planting again.

My basil plant has slowly started to die off at the bottom it's still only small. Don't want to lose it. Any suggestions?

Basil is generally considered an annual, so save some seeds and start again in the spring time

Hi. I am an absolute herb growing virgin so any advice would be greatly appreciated. My question is, I want to start a vertical garden outside my kitchen window, where it will get full sun all morning and into the early afternoon as well. Ive read that basil can be quite a large bush. Is it possible to grow it in tubs on a vertical garden?

Basil would be best grown in medium sized pots at the base of a vertical garden as it is a bush herb and you are correct that it will grow large. If your tubs have reasonable clearance it still maybe possible however large plants also have large root systems so the tubs would have to be large. Dill and fennel may also require pots. Running herbs such as oregano, marjoram, mint and thyme will do well in a vertical garden. In most vertical gardens parsley, coriander and spring onions will also work well. Most Herbs thrive with lots of water and vertical gardens risk drying out so make sure to keep it well watered. In the long term remember to replenish the soil of your vertical garden. Starting small compost from kitchen scraps if you don’t have one already would be good. Basil is a hungry plant and will want lots of yummy compost. Also keep in mind that the running herbs like to take over so ensure they are separated or harvested often enough to keep them in check. Growing herbs is very rewarding. Good luck in your herb gardening endeavours.

How do I stop my basil from just drying up. It is in a pot, on the deck exposed to moderate sun. Deck faces south.
