These are the perfect for plant beginners or at your bach. Simply wash out the vase, gently wash plants roots and replace with fresh water. This can be do about every 2 weeks or if the water is looking greeny.
Keep out of direct sun.
I can sent these, However, I would be weary about sending rural delivery or to the south Island. To send I wrap the roots in wet tissue paper.
Medium has 2 leaves and is in a smaller vase compared with the large which has 3 leaves more root system and are larger vase.
