Growing plants in rectangular pots
Rectangular pot culture implies some precautions, because on the one hand, evaporation in this type of container is much faster than in the open ground and on the other hand, the available substrate is limited.
In hot regions or on a south-facing balcony, your plants may quickly suffer, so it will be wise to choose plants that can withstand these somewhat special conditions without making you a slave to the watering can.

Choosing your potting soil
Of course, for a rectangular pot that remains beautiful throughout the season, a good growing medium should be used: good quality potting soil for flowering plants (which usually already contains fertilizer), or a mixture of garden soil + compost enriched potting soil or fertilizer (slow-release or organic fertilizer).
Pay attention to drainage: the bottom of rectangular pots must be perforated (this may be necessary if drainage holes are missing; this is the case for some plastic containers) and no saucers full of water should be left under the pots.
To marry the good plants in rectangular pot
The first question is: which plants to combine in a rectangular pot? The choice of plants depends first of all on the exposure. Depending on whether the rectangular pot will be placed in full sun or squarely in the shade, the same species cannot be used. Do not plant sunny plants and shade plants together!
Tips for beautiful compositions in rectangular pots
- People think they can save money by buying cheap pots, but most of the time they are not frost resistant and will fall apart over the years. If you want to keep your pots for several years, invest in solid clay, metal or resin pots, but avoid plastics that harden, crack and break in less than two years.
- Plants that share the same rectangular pot should have the same needs: exposure, frequency of watering, type of soil (light and drained, or fresh and rich);
- For flowering plants, choose long-flowering species that will remain beautiful from late spring to fall.
- Don’t neglect plants with decorative foliage, useful to flesh out a composition, to give it durability when flowering runs out of steam, lightness (fine and cut foliage) or color (silvery foliage, red foliage, golden foliage…) ;
- Vary the heights: associate tall, slender plants with low and stocky plants;
- Vary also the shapes of the flowers, the leaves, the textures;
