I have some tumbling tomato plants in hanging baskets but I made a mistake with them, they're made of fibre and had a plastic inner layer which I removed because I assumed it was part of the packaging. But apparently you're supposed to leave it in to retain water? Not an experienced gardener!
Now in this weather my plants are so parched all the time and need watering twice a day because the water runs straight through. Is there any way I can salvage this and help them retain water?
