If you only have a few plants, a clean, brightly lit balcony or verandah with ample air movement should suffice. You can also keep your plants hanging after ensuring that they receive at least a few hours of sunlight. Alternatively, you can keep your plants on a compound wall if you are sure it won\'t sour relationships with your neighbors or your pets won’t knock them off. The main idea is to prevent soil-borne infections like Fusarium from entering your plant. If you have a lot of plants, it would be worthwhile to invest in a bench that is about 90cm above ground level if your greenhouse is open to the elements. If you have a covered greenhouse the bench can be shorter.
