And what spacing do you usually use between the plants?<\/p><\/blockquote>\n<p>Ganna, that is a pretty broad question! A lot of folks prep their beds in the fall. Right now in the spring, you can just put a little compost (or well-rotted manure) and 1 tablespoon of a <a href=\"#editor-note\">balanced granular fertilizer*<\/a> into each planting hole. Mix it really well with the soil and then put your transplants in.<\/p>\n<p>The distance between tomatoes depends on a lot of factors, but on average 12 to 16 inches (30\u201340 cm) is enough. That comes out to about 48 to 52 plants for a standard 10&#215;20 ft (3&#215;6 m) greenhouse.<\/p>\n<p>I am planning to give them a bit more breathing room this year and plant no more than 46. I&#8217;ll do 15 on the side beds and 16 down the middle. I am putting the massive beefsteaks on the western side, mostly hybrids on the eastern side, and the oxhearts right in the center.<\/p>\n<\/div>\n<\/div>\n<div class=\"forum-post\">\n<div class=\"author-header\">\n<div class=\"forum-avatar\">A<\/div>\n<div class=\"author-meta\">\n<div class=\"author-name\">Aleksan9ra (Ludmila) <span class=\"author-stats\">\u2b50 Pro Grower (15,056 posts) Apr.14.2021<\/span><\/div>\n<div class=\"author-geo\">\ud83d\udccd Moscow Region (USDA Zone 4)<\/div>\n<\/div>\n<\/div>\n<div class=\"post-content\">\n<blockquote><p><strong>Russi wrote (Apr 14, 2021):<\/strong> Nah, I soaked them in a little plastic sauce cup on some toilet paper.

It is an absolutely awesome method.<\/p>\n<p>I just want to add a quick warning: both radishes and lettuce only survive the transplant shock if you put them into warm, loose soil.

In the US, a fantastic alternative for the planting hole is an organic tomato-specific blend like <strong>Espoma Tomato-tone (3-4-6)<\/strong> or <strong>Jobes Organics Vegetable &amp; Tomato<\/strong>. Adding 1-2 tablespoons per hole and mixing it thoroughly with the native soil (to avoid burning the young roots) gives the plants a perfect slow-release boost.<br \/>\nAlso, the &#8220;toilet paper in a sauce cup&#8221; method mentioned by Russi is the Russian equivalent of our classic <strong>&#8220;Baggie Method&#8221;<\/strong> (sprouting seeds on a damp paper towel inside a Ziploc bag).
