Gardening advice for August planting and autumn cultivation

August serves as a strategic time for gardeners to replenish empty flower beds with plants that bloom in late summer and autumn. To address gaps left by withered perennials or summer droughts, experts suggest using containerized plants such as Rudbeckia for color and Sedum spectabile (Hylotelephium spectabile) for late-season structure. Regular watering is critical during this period to prevent the warm soil and sun from drying out new root systems.

For vegetable gardeners, high summer temperatures can hinder the germination of autumn lettuce. While lettuce germinates reliably between 0 and 25 degrees Celsius, temperatures approaching 35 degrees Celsius can prevent seeds from sprouting entirely. To combat this, experts recommend placing seed trays in shaded, cooler areas or even in the refrigerator for a few days to encourage successful germination before moving seedlings back outdoors.
