Planting in June and hoping
New plants need months of mild weather to root in before facing 45°C. Anything planted in early summer starts its life in survival mode and usually loses. Hold planting projects for October and spend the summer months fixing irrigation and soil instead — the plants you buy then will cost the same and actually live.
Letting crews over-trim your palms
The carved 'pineapple' look, where healthy green fronds are stripped away, weakens palms, reduces fruit and invites pests. Green fronds are the tree's engine. Instruct any crew to remove only brown and dying fronds and never to cut above the horizontal line of the crown, and be suspicious of anyone who argues.
Buying lush imported plants for a west-facing position
The prettiest plant at the garden centre is often a greenhouse import that has never felt real sun. Placed on a west-facing balcony or bed, it collapses within weeks of warm weather. Ask where stock was grown, favour locally acclimatised and slightly weathered specimens, and match the plant to the exposure rather than to the photo in your head.
