From my perspective as a Foxtail Fern (*Asparagus densiflorus ‘Myers’*), the best time for you to undertake this propagation is during my period of active growth, typically in the spring. This is when the warmer temperatures and increasing daylight hours signal my internal systems to produce new roots and foliage vigorously. Dividing me at this time allows my separated parts to recover quickly from the shock and establish themselves in their new homes before the stresses of summer heat or winter dormancy. If spring is not an option, early autumn can also work, giving me time to settle in before colder weather arrives.
Please begin by hydrating me thoroughly a day before the division. This ensures my cells are turgid and full of water, reducing transplant shock and making the root mass more pliable and easier to work with. When you are ready, gently tip me out of my pot. You may need to tap the sides and bottom of the container to loosen my grip. Handle my stems and tuberous roots with care; I am a resilient plant, but rough handling can cause unnecessary damage that invites disease.
Now, observe the natural structure of my root system. You will see a dense network of fibrous roots and plump, water-storing tubers. My growth originates from a central crown, and you will notice natural lines of fracture where I can be separated. Using your hands, gently tease apart these sections. For tougher, more established clumps, you may need to use a clean, sharp knife or a spade to cut through the root mass. Ensure that each new division has a healthy section of my crown, several tubers for nutrient storage, and a good amount of the fibrous roots to absorb water. Each division should also have several of my upright, photosynthetic stems to support energy production.
Select pots that are only slightly larger than the root mass of each of my divisions. Pots that are too large hold excess soil that stays wet for too long, which can cause my precious tubers to rot. Use a well-draining potting mix, perhaps amended with some perlite or orchid bark, to ensure excellent drainage and aeration around my roots. Place each division in its new pot at the same depth it was previously growing, backfill with soil, and gently firm it around my roots to eliminate large air pockets.
Immediately after potting, give each of my divisions a thorough, gentle watering. This helps to settle the soil around my roots and rehydrates me after the process. Place us in a location with bright, indirect light. Direct, harsh sunlight would be too stressful while we are recovering and trying to establish new root connections. Keep the soil consistently moist but never soggy for the first few weeks. You will know we have successfully taken hold when you see new, bright green spears emerging from the soil, a sure sign that we are happily settled and growing again.
