The present invention generally relates to the field of horticulture. More specifically, the invention relates to wall-mountable plant presentation watering systems and methods that may provide an aesthetic display of plants such as in a picture garden that is designed for optimal plant growth balanced with convenient, no-mess watering. The invention may provide for a series of tiers of individual plants which may be arranged in a desired orientation. Particular embodiments may focus on prescribed periodic watering schedules, where watering of a prescribed, predetermined total growth medium amount is achieved via direct contact of the growth medium with pooled water passing through hole(s) in a substantial bottom of each insert(s) (5) that is established in a water retentive housing (4) the prescribed watering schedule may result in a dry period at a terminal portion of the period of the prescribed periodic watering schedule. A water fill amount may also be prescribed it may result in both passage of air and water into growth medium through hole(s) (9) which, in certain embodiments, are in the substantial bottom of the insert, at the beginning of the period of the prescribed periodic watering schedule (when the prescribed water fill amount is conveyed into the water retentive housing that supports the insert).La présente invention concerne généralement le domaine de lhorticulture.
