Make an impromptu green house for starting cuttings.
In the early spring, you can begin to start your seeds even without a green house. Use a plastic storage bin with a lid to house your seed cups. Keep the soil moist but do not over water. The condensation will accumulate and keep the conditions optimum for your seedlings to develop. Some ventilation is needed in any green house, so cut air holes in the lid to allow free air flow.
