June 2008 Gardening Checklist
- Apply fungicide to prevent and control black spot on roses, if needed.
- Remove faded blooms from peonies, irises, delphiniums and other perennials.
- Apply Preen Mulch Plus Russet Red, Midnight Black or Chestnut Brown to prevent weeds for six months, providing better, more effective controls for a longer period than any other mulch on the market. Preen Mulch Plus is made of premium hardwoods enhanced with two herbicides to prevent broadleaf and grassy weeds from germinating for six months.
- Harvest spring plantings of broccoli, cabbage and peas.
- Apply Preen Vegetable Garden Weed Preventer when transplants or seedlings reach 3 inches tall.
- Discontinue harvest of asparagus and rhubarb in mid-June to allow foliage to develop and store food reserves for next year. Apply an all-purpose fertilizer according to label directions. Water when dry.
- Plan for your Halloween pumpkin. The seed packet will tell you the number of days to harvest. Count backward to find the proper planting date.
- Tie leaves up over the developing heads to blanch (exclude from light) cauliflower when heads are 2-inches in diameter.
- Keep grass mowed regularly, maintaining height about 1/2-inch higher than usual to protect crown of plant from heat stress.
- Supplement water as needed. Most plants need an inch of water every week or 10 days. Newly planted shrubs and trees may require more.
