Black Calabash – This upright, densely foliated, evergreen small tree can reach a height of 30 feet with a variable spread. The large, seven-inch-long, dark green, glossy leaves make it ideal for a small-scale shade or specimen tree, or it can be allowed to grow into a tall screen. Throughout the year, two-inch-long, purplish-white, non-showy tubular flowers are produced on short stalks. These blooms are followed by smooth, shiny green, four-inch-long fruits which have a thin, hard shell and contain numerous 1/2-inch-long, edible black seeds in white pulp.
These are very healthy trees with well established root systems. This Black Calabash is ready to be repotted and enjoyed upon delivery.
Please note: Leaves are often trimmed prior to shipping to reduce transpiration and travel stress. The growth rate of Black Calabash will vary greatly depending on season, soil type, sunlight, temperature and other factors. Always changing!
Black Calabash are very easy to grow tropical fruiting trees that and seem to grow best when neglected. They add a wonderful accent to any outdoor space, garden or patio. In very cold zones a containerized Black Calabash can be brought inside for the winter months. Most will survive a very light frost and quickly return to normal in spring. In the northern end of their grow zone Black Calabash trees should be brought indoors or protected during the winter months.
When you receive your new tree, there is no need to worry about planting right away. Your new tree can be stored for a while by simply placing it in a bucket with about a half inch of water in the bottom and moving it a shady location. You can then add some mulch to the bucket to keep your Black Calabash standing straight. The mulch will also supply nutrients while in storage. This will give you plenty of time to select the ideal location for your Black Calabash.
Most gardeners don’t realize that Black Calabash trees grow very well in patio containers. Allow enough room for growth generally a 18″ to a 30″ diameter, 14″ deep container will suffice. Remember the looser the roots, the taller and healthier your tree will be. When the tree becomes root bound its growth will slow. At that point it is time for a larger pot.
Black Calabash enjoy well drained but moist, rich organic mix. Remember try to stay away from wet, mucky soils.
To help establish your new Black Calabash, fertilize sparingly, biannually with a slow time release 15-5-10. Unfertilized they will tend to grow very slowly. WARNING – The heavy salts in cheaper fertilizers may damage the roots thus killing the tree.
GROW ZONE & LIGHT
Best outdoors if grown in zone 10a-11, find your zone here. This tree requires 85-100% sunlight. Depending on your location full sun is best. The patio zone is 4b-11 which means the potted tree will flourish over the summer months in this zone but must be brought inside for the winter months. (avoid frost)
BEFORE YOU PLANT OUTDOORS
Here at Kens Nursery these trees are grown under 20-40% shade cloth. If you plant directly in full sun you may experience leaf burn. It is best to acclimate this tree to its environment by keeping it outside and slowly moving it into a sunny area over a week or two to avoid stress before planting.
WHAT IS THE SHIPPING SIZE
All trees for sale will vary in size. In the spring, trees are often smaller than trees shipped in the fall. Most trees designated with a (-4, or -3) will arrive in a standard 4 inch or 2.75 inch growers pot respectively. Kens new, reusable, recyclable deep cells are 5 to 7 inches deep and 1 to 2.5 inches in diameter.
