Need help with my tomato hanging basket
I'm about to plant a couple of hanging baskets with tomatoes but have a few questions that I'd like to ask. I am planning on using coir liners in wire baskets, and am going to be planting the determinates 'Tumbling Tom Yellow', 'Hanging basket tomato F1 tumbler', 'F1 Sweet 'n' Neat Cherry' and maybe a pepper 'hot super chilli F1' plant. I know I'm supposed to use plastic inserts inside the coir liners, but I don't have any to hand. So, can I just cut some plastic garbage bags up and use them instead to improvise?
Also should I just plant the tomato plants in the top, or should I be cutting holes in the coir liner and poke various plants through them so they can grow around the sides?
Are there any companion plants I can plant with the tomato plants that you would recommend? Someone recommended French Marigold to me, so I don't know whether that would be a good choice or not. Any help would be much appreciated, thanks.
