Plan balcony containers around the space you have
Planning the layout before you shop avoids pots that don't fit and plants that suffer in the wrong light. Give the assistant your measurements, sun exposure, tenancy rules and anything you know about weight limits.
A text to start with
My balcony is two metres deep and three metres wide, faces south-west and gets about five hours of direct sun in summer. I rent, and my lease bans permanent fixtures. I want herbs, a trailing plant and one larger feature plant. I don't know the floor load limit. Draft a layout with container sizes that stay movable and need no drilling.
Example request. Change the details to fit your situation.What to check in the answer
Floor load is the detail the assistant cannot confirm. Filled containers with wet compost are heavy, and a layout that looks fine on paper may exceed what the balcony is rated for. Ask your landlord or building manager for the limit before buying large pots. Plant suggestions rest on general sun guidance, so wind, reflected heat from walls and the real shading on your balcony may change what thrives.
Your next step
Mark the proposed layout on the balcony floor with tape or empty boxes before you order. If one corner is windier or shadier than the plan assumed, tell the assistant and ask for an adjustment. Get the weight limit confirmed in writing before you fill any large planters.
