June Gardening Guide

June Gardening Guide

June is a vibrant month for gardening in Zone 6, brimming with activity and opportunities to enhance your garden’s beauty and productivity. With the right tools and knowledge, your garden will flourish throughout the summer.

Essential Gardening Tools

To tackle June gardening tasks efficiently, equip yourself with a sturdy pair of gardening gloves, a hand trowel, a hoe, pruners, a watering can or hose with a gentle spray nozzle, and a wheelbarrow for easy transport of soil, mulch, and plants. For weeding, a dandelion digger will make the job less tedious.

Direct Sowing Vegetables and Flowers

June is an excellent time to direct sow several vegetables and flowers. For vegetables, consider sowing beans, carrots, cucumbers, and summer squash. These crops thrive in the warmer soil and will provide a bountiful harvest later in the season.

For flowers, direct sow marigolds, zinnias, and sunflowers. These annuals add vibrant color to your garden and attract beneficial pollinators.

Annual Flowers from the Garden Center

Visit your local garden center to find annual flowers that can be planted alongside your vegetables. Marigolds, nasturtiums, and calendulas are fantastic choices. Marigolds repel pests like aphids and nematodes, while nasturtiums deter squash bugs and improve the flavor of nearby vegetables. Calendulas attract pollinators and beneficial insects.

Harvesting Spring-Planted Vegetables

By June, early spring-planted vegetables such as lettuce, spinach, radishes, and peas should be ready for harvest. For lettuce and spinach, pick the outer leaves to encourage continued growth. Harvest radishes and peas when they reach their mature size for the best flavor. Always harvest in the morning for the freshest produce.
