Thank you for the kind advice.I ended up giving them a foliar spray and watering the roots with warm water mixed with HB-101 and a little bit of liquid humates with iodine (that&#8217;s all I had on hand). I woke up at 5 AM to check on them, and all the tomatoes are standing tall and looking perky! The tops are pointing up and the leaves are spread wide-Big Beef, Pink Unicum, Pink Paradise, and Orange Beef. YAY!<\/p>\n<p>I went ahead and sprayed all the other tomatoes and peppers too, just in case. )))<\/p>\n<p>Have a great day!<\/p>\n<\/div>\n<\/div>\n<div class=\"editor-note\" style=\"background: #eef7ff; padding: 15px; border-left: 4px solid #2196F3; margin-top: 15px; font-size: 1.2em;\"><strong>\ud83d\udc68\u200d\ud83d\udd2c Editor&#8217;s Botanical Note:<\/strong><br \/>\nLudmila&#8217;s advice to keep the plants out of the sun is the most important rule of frost recovery! When plant tissue is frozen, the roots cannot pull up water. If the morning sun hits the leaves, they try to transpire (sweat), instantly drying out and dying. Keeping them shaded allows the ice crystals inside the cells to melt slowly without rupturing the cell walls.<strong>What are Epin and HB-101?<\/strong><br \/>\nIn this thread, Eastern European growers mention their go-to stress relief sprays.<br \/>\n* <strong>HB-101<\/strong> is a Japanese plant vitalizer made from cedar, pine, and cypress extracts.<br \/>\n** <strong>Epin<\/strong> (24-epibrassinolide) is a synthetic brassinosteroid hormone heavily used in Europe to combat cold stress.If you are gardening in North America and your seedlings get cold-shocked, the closest and most effective equivalents are liquid <strong>Kelp\/Seaweed extracts<\/strong> or vitamin tonics like <strong>Superthrive<\/strong>.
