Compared with the prior art, the planting device has the advantages that rainwater can flow downwards to be collected or released, so that the rainwater cannot be accumulated in the planting grooves, the situation that roots of vegetation are soaked by a large amount of accumulated rainwater is avoided, the roots of the vegetation are prevented from being rotted, the survival rate of the vegetation is increased, and the service life of the vegetation is prolonged. And the workload and the cost expenditure for replanting the vegetation subsequently are reduced.
