One major advantage of growing in containers is that you can keep plants free of common soilborne fungal diseases: verticillium and fusarium wilt. A soilless potting mix -- purchased or homemade -- provides a nearly sterile environment for the plants.
Trichoderma is another beneficial fungus, which lives in the soil and attacks harmful fungi such as Fusarium or penicillin. All of these organisms have a pH range in which they are most comfortable and this tends to be the pH range between 6.0 and 7.
The plants are usually vigorous and fast-growing, although many varieties are susceptible to fusarium and other diseases, especially when they are young.
