From our perspective, successful division is entirely about timing. We, Gerbera daisies, are perennial plants with a central crown from which all our leaves and flower stalks emerge. Over one to three growing seasons, this crown becomes congested. Our outer growth thrives, but the center may become woody and less productive, leading to fewer and smaller blooms. The ideal time for this intervention is in early spring, just as we exit our winter dormancy and our new roots (often white and tender) begin to form. Alternatively, early autumn works if you provide us with protection from the coming frost, giving our root systems time to re-establish before the cold fully sets in. Dividing us at these times minimizes shock and allows us to focus our energy on root development rather than supporting flowers.
First, gently lift our entire clump from the soil, taking care to keep our root ball as intact as possible. Shake or wash off the soil to clearly see our root structure. Our goal is to find the natural points of division. Look for healthy, young offshoots or "pups" growing from the outer edge of the main crown. Each new division must have its own set of roots and at least a few healthy leaves or a growing point. Using a sharp, sterile knife, make a clean cut to separate these sections. A ragged tear from pulling us apart can cause significant damage and open pathways for disease. If the central crown is old and woody, it is often best discarded, as its vigor has passed.
Once divided, we are vulnerable. Our root systems have been severely reduced and cannot immediately support the same amount of foliage. To reduce water loss and stress, trim back about one-third to one-half of our older, outer leaves. Replant each new division promptly at the same soil depth we were originally growing at—planting the crown too deep is a primary cause of rot. Firm the soil gently around our roots to eliminate air pockets. Then, provide us with a deep, thorough watering. This settles the soil around our remaining roots and provides the essential moisture we need to begin the recovery process. Do not fertilize us at this stage; our tender new roots can be easily burned by salts in the fertilizer.
Our recovery and successful re-establishment depend heavily on our new environment. Place us in a location with bright, indirect light. Direct, hot sun will scorch our wilted leaves and place undue stress on us while we are trying to grow new roots. Keep the soil consistently moist but never soggy; our compromised roots are highly susceptible to rot in waterlogged conditions. Within a few weeks, you should see signs of new growth emerging from the center of the crown. This is the definitive signal that our root system has taken hold and we are successfully on our way to becoming a strong, independent plant, ready to reward your care with a new season of vibrant blooms.
