How to keep Geranium Ocellatum.
Light
Black eyed geranium comes from bright, open habitats and does best in full sun. It can withstand partial sun but favors direct sunlight for optimal growth. This plant, which can be annual or biennial, is recognized for its sun-loving habit.
Water
Black-eyed geraniums, which originate from temperate regions, require consistent moisture and thrive in evenly moist soil. During their growing season, water them every two weeks, adjusting for any seasonal rainfall. Once established, these plants exhibit moderate drought tolerance but still need stable hydration to flourish.
Temperature
Black-eyed geranium is native to regions where temperatures range from 68 to 95 °F (20 to 35 °C). Consequently, it does best within that span. In seasons when temperatures go above or below this range, adjustments to its surroundings may be necessary.
Fertilizer
When most of the blooms on the Black eyed geranium have opened to full size, it's time to resume fertilizing. Around the period when bloom production is at its peak, begin fertilizing again every three to four weeks, as the weather allows. Then, once the Black eyed geranium starts producing fewer new blooms, stop fertilizing; there's no need to feed it when it can no longer produce more blooms.
Pruning
To promote optimal growth and vibrant blooms, it's best to prune black-eyed geraniums in early to late spring. During this time, remove dead stems and shape any overgrown sections. Annual pruning helps enhance bloom production and boosts the plant's vigor. Be sure to use clean, sharp tools to minimize the risk of disease, and take advantage of the plant's natural growth cycle.
