I was digging the soil with my excavator and adding peat/compost to improve the soil structure as I had this pest attack by larvae which will kill my plants. Then I filled each pot with compost, added compost and sieved the soil to get rid of the lumps. I then placed the plants in each pot and watered them. I watered each pot once to moisten the roots, then twice a week for the next two weeks to eliminate any fungus or bacteria. After two to three days, I would leave the planters in the shade.
