Since sugar cane is a type of grass, it thrives on nitrogen-rich fertilizers. You can fertilize the sugar cane plants with standard grass fertilizer, or go for an organic option: chicken manure. Fertilizing just once, when the sprouts first emerge, will help the sugar cane grow strong and healthy so you'll have a good harvest in the fall. Sugarcane requires little maintenance except for weeding. Weeds could choke the new sprouts before they have the chance to grow. Constant weeding is necessary until the canes grow large enough to produce shade and choke harmful weeds on their own. A number of pests and diseases can impact sugar cane. Pests such as borers and insects are more likely to impact a crop when they experience waterlogged conditions, while diseases can cause fungal growth and rot stocks. Check your sugar cane regularly for pests or rotting, and take preventative measures to discourage pests and diseases whenever possible.  Selecting sugar cane varieties that are resistant to diseases and viruses known to affect crops in your area is one of the best pest management strategies.  The application of controlled amounts of appropriate fungicides or pesticides may help prevent the propagation of a pest or disease within your crop.  If you do spot a plant that appears to be infected with pests or a disease, remove it immediately. Sugar cane plants should be left to grow for as long as possible before the first frost of the year. If they are left in the ground after the first frost, you will not be able to use your plants to make sugar syrup.  If you live in a place with long, cold winters, play it safe and harvest your sugar cane by the end of September. If you live in a place with mild winters, you may be able to let your sugar cane grow until late October.

The mature stalks will be tall and thick, similar to bamboo, so simple garden shears won't cut it. Use a machete or a saw to cut the sugar cane as close to the ground as possible, so you'll be able to make use of as much of the plant as possible. You don't want to damage the roots of the established sugar cane plants. If you leave the roots in the ground, your sugar cane will come up again next year. Be sure to wear gloves since the leaves are quite sharp. Use them to cover up the planting bed. The leaves will act as an organic mulch that will protect the sugar cane roots over the winter. If you don't have enough leaves to cover the whole bed, use some extra straw to finish the job.
سمد قصب السكر بالنيتروجين. أزل الأعشاب الضارة من فرش النبات بانتظام. انتبه من الآفات والأمراض. انتظر حتى الخريف للحصاد. استخدم المنجل لقطع القصب على مقربة من الأرض. لا تخترق الأرض. أزل الأوراق عن قصب السكر المقطوع.
