Plant Care Guides

Welcome to the Grow Pro plant care corner. No green thumb required — most houseplant troubles come down to three things: water, light, and soil. Get those roughly right and your plants will do the rest. Here are the basics we walk through with customers at the booth every weekend.

Watering Basics

More houseplants die from too much water than from too little. Before you water, push a finger two knuckles deep into the soil:

  • Dry down deep? Water thoroughly until it runs out of the drainage holes, then empty the saucer. Roots hate sitting in a puddle.
  • Still damp? Walk away and check again in a few days.
  • Exceptions: Calatheas and prayer plants like their soil evenly moist (never soggy, never bone dry). Succulents, cacti and snake plants want the opposite — let them dry out completely between drinks.

Water less in winter. Growth slows down, and wet soil plus low light is the fastest route to root rot.

Light, Explained Simply

  • Bright indirect light (what most tropicals want): a few feet from a sunny window, or right in an east window. The plant can see the sky but the sun’s rays don’t land directly on the leaves.
  • Medium light: a bright room, several feet back from the window. Fine for pothos, aglaonema and ZZ plants.
  • Low light: a north window or a room’s interior. Very few plants thrive — snake plants and ZZ plants tolerate it best.
  • Direct sun: south or west window sills. Great for cacti and succulents, a leaf-scorcher for most tropical foliage.

Variegated plants (white, cream or pink in the leaves) need more light than their all-green cousins to hold their colour. If new leaves come in plain green, move the plant closer to the light.

Humidity

Most tropical houseplants come from humid forests, and Ontario winters are dry. Brown, crispy leaf edges are the classic complaint. What helps, in order:

  1. Group plants together — they share moisture from their leaves.
  2. Run a small humidifier nearby (the only fix that truly raises humidity).
  3. A pebble tray with water under the pot helps a little. Misting feels good but does almost nothing — enjoy it, just don’t count on it.

Ferns, calatheas and nerve plants are the humidity lovers. Cacti, succulents and snake plants couldn’t care less.

Repotting, Step by Step

Repot when roots circle the drainage holes, the plant dries out suspiciously fast, or growth stalls in spring. Only go one pot size up (about 2 inches wider) — a huge pot holds too much wet soil.

  1. Water the day before so the root ball slides out easily.
  2. Tip the pot, support the plant, and ease it out. Tease compacted roots gently with your fingers.
  3. Add a layer of fresh mix to the new pot, set the plant at the same depth it was growing, and fill around the sides.
  4. Water well, let it drain, and keep it out of harsh sun for a week while it settles.

Our potting soils and growing mediums include chunky, fast-draining mixes for aroids (philodendron, monstera, alocasia) and gritty blends for succulents and cacti.

Soil Basics

Roots need air as much as water. A good indoor mix is light and chunky — if it pours out of the bag like dense, wet cake mix, your tropicals will struggle. Look for mixes with bark and perlite, and feed through the growing season with a balanced plant food. Not sure which one your plant wants? Bring a photo to the booth and we’ll match you up.

Common Problems

  • Yellow leaves: one or two old leaves yellowing is normal shedding. Lots of yellow at once usually means overwatering — check that the soil isn’t staying wet for weeks.
  • Brown, crispy tips: low humidity, inconsistent watering, or fertilizer salts. Flush the soil with plain water every few months.
  • Drooping: check the soil first. Dry and drooping = thirsty (it should perk up within hours of watering). Wet and drooping = roots in trouble; let it dry and improve drainage.
  • Pests (fungus gnats, spider mites, mealybug): gnats mean the topsoil stays too wet — let it dry between waterings. For mites and mealybug, wipe leaves down, isolate the plant, and treat promptly. Bring us a photo — we’ll help you ID it and pick a treatment.
  • Leggy, stretched growth: not enough light. Move it closer to a window or add a grow light.
