How To Propagate Phlox: Step-By-Step Guide For Beginners

Introduction to Phlox

Phlox is a genus of colorful, fragrant flowering plants in the Polemoniaceae family. It includes both annuals and perennials, most of which grow upright with masses of flowers. They come in a variety of colors including purple, pink, white and lavender. Commonly known as “creeping phlox” or “moss phlox”, these low-growing species are an excellent choice for ground cover or rock gardens. Phlox can also be planted in beds or containers and grown alongside other flowering plants to create a stunning show of color in the garden.

Propagation Methods

Phlox can be propagated through several methods including by seed or cuttings taken from existing plants. The best time to take cuttings depends on your climate but is usually when new growth appears in early spring or fall just before frost sets in for winter dormancy. Here we will discuss two propagation methods: taking stem cuttings and sowing seeds directly into soil outdoors.

Taking Cuttings

To propagate phlox using stem cuttings you will need a pair of clean shears/scissors and some rooting hormone powder (optional). Begin by cutting off stems that have good green growth at least 4 inches long – they should not have any buds yet – then remove all leaves except top two sets so there is only one node where leaves were removed left exposed; this area will act as root initiation point once potted up later on! Place the bottom end (node) into rooting hormones if desired before planting it vertically about 2 inches deep into moist potting media such as perlite mixed with peat moss; make sure there are no air pockets around roots because this could cause them not to establish properly due insufficient moisture retention – water lightly afterwards but don’t overdo it! Keep medium temperatures between 65-85 degrees Fahrenheit during day/night cycles respectively until new growth begins appearing after about 6 weeks – then transplant potted specimens into larger pots filled with regular potting mix if desired otherwise transplant straight away out onto final growing spot within garden (make sure its well drained!).

Sowing Seeds Outdoors

Propagating phlox via direct seeding outside requires slightly more work than taking stem cuttings since you would need to first prepare soil mixture consisting primarily organic matter supplemented with coarse sand particles & manure followed by scarifying seeds prior sowing – scarification helps break down hard outer coating found on many flower seed varieties making them easier for germination process! After prepping soils & treating seeds accordingly simply broadcast small amounts evenly over prepared surface then press gently down onto substrate surface while raking lightly across it using rake head tilted at 45 degree angle (this ensures even coverage); next step is watering thoroughly using gentle spray nozzle attachment connected hosepipe until entire bed has been drenched completely – keep maintaining optimal moisture levels throughout germination period without causing excessive run-off which could lead development fungal diseases like damping off disease affecting young seedlings adversely! Finally when primary shoots start appearing cautiously thin out weaker ones allowing healthier specimens adequate space apart from each other before finally transplanting those individuals selected onto their final growing location within landscaped environment once danger from frosts has passed .


With proper care and attention, propagating your own phlox can be easy and rewarding endeavor that brings delightful beauty to landscape every year thereafter – whether choosing method based upon taking stem cuttings indoors under controlled warm conditions versus sowing directly outdoors after preparing suitable composted soils appropriately either way results should still remain similar regarding production vibrant displays rich hues ranging anywhere between purples right through whites even lavenders depending variety chosen originally check particular requirements individual cultivar beforehand ensure success throughout lifetime plant maintenance program undertaken regularly !
