Planting Time?• Warm mild weather excites us to plant• Soil temperature is what matters• Seed and transplants grow best at 65 degrees F• Monitor soil temperature with soil probe or computer

• Monitors current weather statistics• Stores past weather stats

Weed Control in Shrubs• Preemerge-Preen, Treflan, Gallery– Apply early (like now) and again 60 days later– Must have rainfall or irrigation to activate– Mulch or landscape fabric
• Postemerge– Round-up, Ornamec– Atrazine selectively– Casoran granular herbicide is labeled for shrubs and other ornamentals
Lawn Fertilization• Fertilize 3 times per year• 3 lbs of Nitrogen per year
Calculations• Apply 30 lbs 10-10-10 per year• Apply 10 lbs 10-10-10 each application to get
30 lbs total• 10 lbs X .10(%)=1 1x3=3 lbs
When Do I Apply Fertilizer• Apply 1st application after spring green-up• Apply 2nd application mid July• Apply 3rd application September• Do not apply in Winter or October

and excess branch growth.
