Keep Summer Containers Blooming

Hanging baskets and planters bring instant colour to patios and entryways, but they also dry out quickly and burn through nutrients faster than garden beds. With a little steady care, you can keep them lush, full, and blooming beautifully all summer long even in Kamloops’ 30–40°C heat.

Watering: The Most Important Task

Containers dry out far faster than in‑ground plantings, especially when exposed to sun and wind.

How to water well:

• Water once or twice daily during hot spells
• Water until it runs out the bottom of the pot
• Morning watering is best; add an evening check during heat waves
• Avoid wetting foliage to reduce mildew

Signs your basket is too dry:

• Leaves feel crisp
• Soil pulls away from the pot edges
• Flowers stop opening

If soil becomes hydrophobic, soak the entire pot in a bucket for 10–15 minutes to rehydrate it.

Regular Grooming Keeps Plants Blooming

Most annuals bloom on new growth. A little trimming keeps them fresh and encourages more flowers.

Weekly tasks:

• Pinch off spent blooms (especially petunias, calibrachoa, geraniums)
• Trim long, straggly stems by 2–4 inches
• Remove yellowing or damaged leaves
• Rotate baskets so all sides get sun

Monthly tasks:

• Give trailing plants a light “haircut” to keep shape
• Thin out crowded stems to improve airflow

This gentle grooming prevents mid‑summer collapse and keeps baskets looking full.

Sun & Heat Management

Kamloops sun can be intense.

• Move baskets to afternoon shade during heat waves
• Use shade cloth for delicate annuals
• Add a thin layer of mulch (fine bark or coco coir) to help retain moisture

Plants like petunias, verbena, and geraniums love heat; bacopa, fuchsia, and lobelia appreciate a break from the afternoon sun.

Short & Simple Fertilizing Guide

Containers use up nutrients quickly, but fertilizing doesn’t need to be complicated.

The Easy Formula

1. Monthly slow‑release feeding

• Use worm castings or a gentle granular fertilizer (4‑4‑4 or similar)
• Sprinkle on the soil surface and water in

2. Light liquid feeding every 1–2 weeks

• Choose a bloom‑boosting fertilizer with more phosphorus & potassium than nitrogen
• Use at half strength to avoid overgrowth

This “low and slow” approach keeps plants blooming without overwhelming them.

Check Soil Level & Pot Health

Over the season, soil settles and roots fill the pot.

• Top up soil if it sinks below the rim
• Ensure drainage holes are clear
• Watch for roots growing out the bottom (a sign they’ll need Part 2!)

Monitor for Pests

Heat and dryness can bring on spider mites, aphids, and whitefly.

• Check undersides of leaves weekly
• Rinse foliage with water to reduce mites
• Use insecticidal soap if needed

Healthy, well‑watered plants resist pests far better.
