Blanket Weed<\/p>\n\n\n\n

One of the most common ways blanket weed (string algae) gets into a pond is through new plants from nurseries or garden centres<\/strong>. Even healthy-looking plants can carry small strands or spores of algae without it being obvious at first.<\/p>\n\n\n\n

\ud83e\udeb4 Why it happens<\/h3>\n\n\n\n
    \n
  • Plants are often grown in shared water systems<\/li>\n\n\n\n
  • Blanket weed can easily spread between plants<\/li>\n\n\n\n
  • Small fragments or spores are hard to spot when buying<\/li>\n<\/ul>\n\n\n\n

    \ud83d\udca7 Simple way to reduce the risk<\/h3>\n\n\n\n

    Before adding any new plants to your pond, it\u2019s a good idea to quarantine them for a couple of weeks<\/strong>.<\/p>\n\n\n\n

    How to do it:<\/strong><\/p>\n\n\n\n

      \n
    • Place the plants in a bucket or container of water<\/strong><\/li>\n\n\n\n
    • Leave them for 2\u20133 weeks<\/strong><\/li>\n\n\n\n
    • Keep them somewhere light, but not in full scorching sun<\/li>\n<\/ul>\n\n\n\n

      \ud83d\udd0d What to look for<\/h3>\n\n\n\n

      During this time:<\/p>\n\n\n\n

        \n
      • Check for any fine green threads or slime forming<\/strong><\/li>\n\n\n\n
      • If blanket weed appears, remove it by hand<\/li>\n\n\n\n
      • Rinse the plants thoroughly before they go into the pond<\/li>\n<\/ul>\n\n\n\n

        \u26a0\ufe0f Extra tip<\/h3>\n\n\n\n
          \n
        • Don\u2019t pour the quarantine water into your pond<\/li>\n\n\n\n
        • If needed, wash off the roots and replant in fresh aquatic compost<\/strong><\/li>\n<\/ul>\n\n\n\n
          \n\n\n\n

          \ud83c\udf31 The bottom line<\/h2>\n\n\n\n

          Quarantining plants for a couple of weeks is a simple step that can help you avoid introducing blanket weed<\/strong> into your pond. It\u2019s not foolproof, but it can make a big difference\u2014especially if you\u2019re adding several new plants at once.<\/p>\n\n\n\n
