Now that you've received your plants, how should you go about preparing them for their new home? Firstly, identify whether your plants are potted, lead-bunched, or loose/floaters. With the latter, you should be good to go with planting them straight away! Just make sure to remove any dead/dying leaves before adding any loose plants or floaters. For lead-bunched plants, the lead can sometimes damage the stems by crushing or bruising them, therefore we've found it best to cut the stems just above the lead, and then plant, ensuring just the healthy stems remain. The plants will soon sprout new roots, and settle in nicely.
With potted plants, the root structure is usually buried into Rockwool, an inert media that aquatic nurseries use to maintain nutrition and moisture when growing the plants. Depending on the type of plant that you get potted, you will need one of three approaches:
Stem plants, such as Ludwigia or Rotala, simply cut the stems off where the Rockwool begins, and plant them. You may also try to remove as much of the Rockwool if you would prefer to keep some of the plant's roots if you are worried the conditions in your tank might not be the best, to give your plant a better chance of adapting to its new environment.
With bulb or rhizome plants, such as Java Fern, remove as much Rockwool as you can without damaging the roots (doing so when under running water can make it a bit easier). Then you want to trim all but about 1/2-1 inch of the roots, rinsing the remaining Rockwool from the roots afterward. This is then ready for planting, don't worry if you can't remove all of the Rockwool, it's inert and won't harm anything in your substrate or aquarium!
Lastly, if you have carpeting plants such as Monte Carlo or Dwarf Baby Tears that have a very delicate root structure. For these, trim the Rockwool to about 1/2-3/4 inch, then cut the plant into smaller clumps. Plant these straight into your substrate, this will help your carpet spread quicker and healthier.
