Sorry to burst your bubble of excitement but black roses don’t actually exist, even though scientists and growers are trying their best to grow one. ‘Black roses’ are just highly pigmented dark roses that you can grow even at home with the right tools, practices, and nutrients.
Black Rose Cultivation:
You can grow your own plant of black roses with a hint of burgundy or red and a velvety texture easily at home following these steps:
The simplest way to begin your rose garden is to develop a black rose plant from a dormant bare-root rose bush or an existing container-grown seedling bush. When touching your new rose plant, use gardening gloves to protect your hands from black rose thorns. Pick a spot in your garden that gets 5 to 6 hours a day of direct sunlight. Your black rose bush's roots need to have drainage that is away from them in loose soil. Your plant will suffer if the soil is consistently moist or is overwatered.
Before planting, bare-root roses need to soak overnight, while container roses need to have their roots shaken free of the compressed, tightly-packed soil. To give your black roses room to expand in the future, space them apart. Make a hole that is 15 to 18 inches broad and as deep as the roots of a rose.
Return the loose soil you removed to create the hole for your black rose bush and treat it at planting time with a rose-specific fertilizer.
Water the soil thoroughly. Mulch helps roses develop properly, so apply mulch around the base of the plant, being careful to pull the mulch away from the stem so that it is not in contact with the canes. For the duration of the hottest months of the year, make sure you water your black roses twice a week.
How to sow black rose seeds:
A black rose plant needs to be propagated from seeds, which takes a bit more time than planting a seedling. Before any new germination can take place, rose seeds must first undergo a phase of cold stratification. Depending on the classification of your rose, it might be necessary to soak the seeds for 12 to 24 hours before storing them in the fridge for up to 10 days to terminate the cycle of dormancy. It's crucial to keep in mind that not all seeds from black rose plants will produce plants that produce black roses.
In shallow seed trays filled with 3 to 4 inches of rich, moist soil, you can also do this by planting your black rose seeds. The seed trays can be wrapped with plastic wrap or a plastic bag and kept in the refrigerator for 10 to 12 weeks after the seeds have been sown. This replicates the seeds' natural cold stratification process. The seeds will naturally go through the cold stratification process with the seasons when planted outside in the late summer or fall and grow in the spring.
How to grow black rose from seeds:
It can take a black rose plant grown from seeds two to five years to fully mature. Within two to three weeks of being exposed to sunlight and water when developing a black rose bush from seed, you should start to notice sprouting growth.
If you plant black rose seeds in seed trays and chill them for stratification, the seeds will require a warm environment to germinate. To flourish, young rose bushes require temperatures of at least 70 degrees and five to six hours of direct sunlight daily.
You can expose your seed trays to direct light by using a hydroponic lighting system, an indoor plant light, or the sun itself. Young seeds and seedlings shouldn't be overwatered because doing so can harm the roots.
