Pot Plants

  • Plant succulents in pots, hanging baskets and even garden beds; these tough customers laugh at the heat.
  • Plunge potted indoor and shade plants into mulch in shade to keep plants moist and alive if you go away for holidays.

Feeding

Soil

  • Avoid light and frequent watering, rather water deeply and infrequently, allow the soil to dry out between drinks.
  • When fertilising with granular plant foods during summer, wet the soil first then apply fertiliser to moist soil and follow up with another watering.

Flowers & Ornaments

  • Hanging baskets are particularly vulnerable to drying out through wind and heat. Move to more protected locations if possible and treat with Baileys Grosorb wetting agent.
