If we have many plants, surely we extremely use the space we have, never miss a place that we can plant. I use the ground for those plants that require less sunlight. The best thing is the microclimate forms and then easily allows the diversity of plants. The big problem is the snail issue, I can't stop them eating the plants for food due to I don't use metaldehyde. During the hot and rainy season, the giant African land snails are so active and eager to feed themselves all the time. Primulina is their favorite. Although there is loss of plants but the advantage of ground planting is more and the flower still blooms.
