How to Grow Sugarcane in a Greenhouse

Technically a tropical grass, sugarcane is grown as an edible crop in tropical climates that have mild winters. Sugarcane can grow up to 13 feet tall, but it can be harvested when it’s only 3 feet in height. You can easily grow sugarcane in your greenhouse from sugarcane stalks sold at most health food or ethnic grocery stores for chewing. As long as you have heating elements set up in your greenhouse, your sugarcane-growing experience will be simple and rewarding.

Saw the tops of the sugarcanes to make them into 5 1/2- to 6-inch seed pieces, also called “setts.” Use only the freshest sugarcanes for planting.

Fill a seed tray that has drainage holes in the bottom with a mixture of equal parts grit, such as coarse sand, and organic compost.

Lay the setts flat on top of the mixture, and cover them with a light sprinkling of compost.

Sprinkle or mist the compost and setts with warm water from a spray bottle.

Place your seed tray inside a covered frame or a clear plastic bag, or place a clear seed tray cover on top of the tray.

Place the seed tray on top of a heating element and in bright light in your greenhouse, set to warm the compost in the seed tray to at least 68 to 70 degrees F. Maintain air temperatures in your greenhouse at 65 to 75 degrees.

Water the compost and setts very lightly, if at all, until the canes sprout, which usually takes about three weeks.

Remove the plastic bag or covered frame from the seed tray after the shoots emerge and grow to about 3 inches tall.

Fill 6-inch-diameter planter pots that have drainage holes in the bottom with a mixture of equal parts potting soil, organic compost and coarse sand or grit.

Carefully remove the sugarcane seedlings from the seed tray, and plant them individually in the pots.

Place the pots in bright light and water your sugarcane plants two or three times each week to thoroughly moisten the potting mixture and until water drains freely from the bottom of the pots.


Things You Will Need

  • Sugarcane stalks
  • Hand saw
  • Seed tray
  • Grit, such as sand
  • Organic compost
  • Water spray bottle
  • Plastic bag, covered frame or clear seed tray cover
  • Bottom heating element
  • Planter pots, 6-inch diameter
  • Potting soil
  • Knife
  • Gloves


  • Repot your sugarcane plants as soon as they fill their pot, transferring the plant into pots that are about 1 ½ times the size of the current container.
  • Keep the potting mixture evenly moist at all times; don't allow it to dry out.
  • To harvest your sugarcane, cut down the sugarcane stalk when the plant reaches about 3 feet tall. Peel off the outer leaves.


  • Wear gloves and use caution when handling sugarcane stalks, because the leaves are very sharp.
