Pollinators like bees, butterflies, moths, and birds play an important role in pollinating your vegetable garden and supporting a healthy ecosystem. However, habitat loss, disease, and pesticide use have contributed to the decline of these species. You can help pollinators by selecting a wide variety of flowering plants, guiding pollinators to your garden by planting in groups rather than single plants, and providing a source of clean water.  For a list of pollinator-friendly plants, visit: Pollinators Are Unsung Heroes of Planet Earth. You can get pollinator plants -- both native and non-native -- at the Spring Garden Market on April 13th.

The simplest definition of a weed is “a plant growing where it’s not wanted.” Most home gardeners prefer to not have weeds growing among their landscape plants and in their vegetable gardens. However, weeds do have many benefits. For instance, they can help to control soil erosion, provide food for birds and nectar for honey bees, and create habitat. Some weeds are even edible. On the downside, weeds compete with landscape plants for water, nutrients and sunlight, and can be invasive.

The best ways to manage weeds that you don’t want growing in a particular location include hand-pulling, cutting or shallow hoeing. Use mulch to suppress weed growth. For more information, see Weeds in Landscape.

Gardening enthusiasts are well acquainted with the havoc that slugs can wreak on their cherished plants. However, a noteworthy shift in perspective comes from The Royal Horticultural Society (RHS), the foremost garden charity in Britain, which no longer classifies these creatures as pests. Instead, the RHS highlights the crucial role that slugs play in fostering a diverse and healthy ecosystem.
