π₯ June Chores For The Vegetable Garden
- β Plant tomatoes, peppers, squash, cucumbers and beans now if they are not in yet.
- β Sow a second row of lettuce, radishes and beans every two to three weeks for a steady harvest.
- β Thin carrots, beets and radishes so each one has room to grow.
- β Stake or cage tomatoes before they sprawl.
- β Pick peas, radishes and early lettuce often; picking keeps them producing.
- β Side-dress heavy feeders like tomatoes and squash with compost or a balanced fertilizer when they start to flower.
π§ Watering The Right Way
Most gardens need about one inch of water a week, from rain plus watering. Water deeply in the morning so leaves dry before evening, which helps prevent disease. Push a finger two inches into the soil; if it is dry, water. Containers and hanging baskets dry out much faster and may need water every day in hot spells.
π Mulch Now, Weed Less Later
Spread two to three inches of mulch (shredded leaves, straw or wood chips) around plants once the soil has warmed. It holds moisture, keeps roots cool and blocks most weeds. Keep it a few inches away from stems and tree trunks.
πΌ Feed Containers And Baskets
Potted flowers use up their nutrients fast. Feed containers and hanging baskets with a liquid fertilizer every two weeks through summer for steady blooms.
