Basjoo is the hardiest Banana plants on earth. It is a very fast grower capable of growing up to two feet in one week. This hardy banana tree is a very heavy feeder. This means if you want your plants to grow quickly and well, you must feed it on a regular basis. Liquid plant food is recommended every 2 weeks to achieve maximum nutrition for maximum growth.
Plant your hardy banana plants in full sun, but be aware that windy conditions can cause the fragile leaves of the banana plants to shred. As far as watering, hardy bananas love the moisture but the soil must drain well. If the soil does not drain well, the banana plants will rot.
If you are treating your banana plants well, they will produce a new leaf every 5-7 days outdoors. If a new leaf does not produce in this time frame, the plants are either underfed or under-watered.
Winter care is important. After your Basjoo Banana tree has been hit by the first frost, cut the hardy banana to the ground. Don’t let it rot back because it can continue rotting down into the roots which will kill the plants. Cover with a good 6 to 8 inches of mulch and then cover the mulch with a sheet of plastic. You must keep the mulch dry or the banana plant roots will become wet and rot. In the early spring, before growth starts, remove the plastic, remove most of the mulch and let the plant come back when the ground warms up.
How To Plant A Basjoo Banana
Dig a hole two times as wide and slightly deeper than the root ball. Don’t amend the soil too much. The roots do better when starting out in soil much like what they’ll encounter beyond the planting hole.
Measure the depth of the root ball and also the planting hole as you dig, then measure again before positioning the plants.
If the roots are tangled or pot-bound, loosen them with your fingers, a cultivator claw or even slice through them with the sharp edge of a spade to break them up and encourage them to grow outward.
Position the plants so that the point where the trunk meets the roots is only an inch or so below the soil level.
Proceed with filling in around the roots with soil, tamp lightly with your feet, water well and add mulch in a doughnut shape around the plants, but away from the trunk.
