How to Care for Hanging Petunia Baskets All Summer

Provide proper care for hanging petunia baskets to keep them beautiful all summer.

Overview

Large hanging baskets of petunias are a porch and deck staple. Modern varieties need minimal deadheading—just occasional shaping for all-season appeal.

Step 1: Sun Exposure

Hang where they get 6+ hours of direct sun daily.

Step 2: Daily Watering

Check soil daily—finger 1 inch deep. If dry, water until it drains from the bottom. Critical in summer heat.

Step 3: Rotate Weekly

Turn basket 180° each week for even light and balanced growth.

Step 4: Fertilize Biweekly

Use liquid fertilizer every 2 weeks per package directions for basket size. Water first if soil is dry, then fertilize to prevent root burn.

Step 5: Mid-Summer Trim

When stems get leggy (mid-summer), shear back half the overgrown stems. A few days of shade helps recovery. No deadheading needed on modern varieties.
