As temperatures begin to rise and the final traces of winter fade, many gardeners are eager to get outside and begin planting. Black explained that while enthusiasm is high this time of year, patience is essential due to the unpredictable nature of Midwest weather. Northern Illinois falls within USDA Hardiness Zone 5, which plays a key role in determining what plants will thrive in the region. Gardeners are encouraged to select plants suited for this zone and to remain mindful of the typical growing window, which runs from around Mother’s Day through late October.
For those eager to begin, Black highlighted that not all planting needs to wait. Cold-hardy crops such as carrots, radishes, and leaf lettuce can be planted early in the season. However, more temperature-sensitive plants, such as tomatoes, peppers, and eggplant, should be held until the risk of frost has passed, typically around mid-May. These crops generally require between 75 and 100 days to reach maturity, making timing an important factor for a successful harvest.
Beyond planting timelines, the conversation also focused on preparation and garden maintenance. Black emphasized that gardening practices can vary widely depending on the individual, noting that while there are best practices, each gardener ultimately develops their own approach. He encouraged gardeners to use natural materials like leaf litter as compost, which can enrich soil with nutrients as it breaks down. Incorporating this organic matter into garden beds can improve soil health and support plant growth throughout the season.
Another important tip was to delay the early spring cleanup. While many are eager to clear away last year’s plant debris, Black noted that pollinators often overwinter in leaf litter and hollow plant stems. Allowing a brief period of warmer weather before clearing these materials gives beneficial insects time to emerge, supporting a healthier garden ecosystem.
Seasonal conditions were also addressed, including the importance of spring rainfall. With lower-than-average snowfall during the winter, soil moisture levels may still be recovering. Consistent rainfall in April and proper watering practices in the coming months will be critical to maintaining healthy plants, especially as temperatures begin to climb.
In addition to gardening advice, Black shared details about upcoming local programs aimed at engaging the community. In Sterling, the Extension office is offering two hands-on opportunities for youth and families. The Junior Garden program, geared toward ages 12 to 18, will begin May 12 and provides participants with practical experience in planting and maintaining both flowers and vegetables. Registration for this program closes May 3.
A second initiative, the Seedling Explorers program, is aimed at younger children and families. This drop-in garden club begins May 26 at 10 a.m. at the Sterling Township Community Garden and focuses on introducing preschool-aged children to gardening through interactive, hands-on activities. The program is designed to be accessible and family-friendly, encouraging participation from parents, grandparents, and siblings alike.

The episode also introduced a new interactive segment for Along the Rock, inviting listeners to submit their gardening questions. Send questions to alongtherock@radar.online. These questions may be featured in future episodes as part of an ongoing seasonal series with Black, providing continued guidance and insight throughout the growing season.
