Getting ready for a season, it will be last frost day in a week

I had build raised bed last year and it's awesome, but this year I planted to much seedlings so had to expand my setup.

• planing to do 3 small raised beds for tomatos, each 20m × 1m
• added posts each 10m and steel cable in pvc wrap
• will be seeding tomatoes each 0.5m in 2 rows (aprx 80 on each raised bed) and use strings tight to steal cable for suport
• will add drip irrigation in the middle of each bed
• will be mulching heavily

In my existing raised bed will be aprx 50-60 hot and sweet pepers and will also add drip irrigation
