I have just pulled out about 10 basil plants ( lots of seedlings coming up) because I am so sick and tired of the cloud of grasshoppers taking residence in our veggie patch and eating the basil... Basil is one of my favorite herbs ,but these grasshoppers are really owning my patch...any advise would be much appreciated.

Try shade cloth or mossy netting over them for a few weeks.

Thanks Mike for the hint. I spotted an unusual roll of shade cloth at Bunnings, and it was very closely woven- I think it was a beige colour. But I got confused with all the price tags and descriptions that I just gave it a miss.(looks expensive) What is mossy netting and where do you buy it? Blessings to you on this fine day.

If you'd like to save money then go to an op-shop and pick up some net curtains. They're easy to find and will be very cheap. That will let the sun and air in but keep the bugs out

Mossy netting is mosquito netting - in the old days you hung this over your bed to keep the mosquitos out. They sell it at Spotlight - about $7/mr. What width I don't know. 70% shade cloth at Bunnings is approx. $5-7/mtr - that is 1.83m x 1mtr. It has multi uses in gardening.

Thanks Mike. With basil, do the leaves need to be picked small (do they go spindly/woody) or can they be picked big?

I planted Basil seeds 19 Feb they come up lovely, but 5wks later they are still 3cm tall. They get plenty of sun and enough water why arent they growing anymore.

How many hours of sun would you recommend for basil? My back balcony only receives 4 hours of direct sunlight in Summer. I'm currently living in a new apartment and am expecting this number to decrease as it approaches Winter. Will the basil survive in this environment?

Seed selling company recommends full sun. Just give it a try and see what happens.
