Spacing<\/strong><\/p>\n\n\n\n At maturity, broccoli, cauliflower, and cabbage (BCC) plants can span four feet across. (I just measured one cauliflower plant in my yard at four feet three inches wide.)<\/p>\n\n\n\n But that doesn\u2019t mean they need to be planted that far apart. There\u2019s no harm in spacing them more closely such that their leaves touch those of neighboring plants. In fact, the farthest I\u2019ve ever planted BCC apart is a bit over two feet.<\/p>\n\n\n\n How closely can they be planted? For most varieties, 1.5 feet is as crowded as will still give maximum size heads. I have planted as close as one foot apart (within a row, with more space on the sides), but the plants seemed a bit stunted at that spacing.<\/p>\n\n\n\n Interplanting<\/strong><\/p>\n\n\n\n So you put these little plants into the ground spaced 1.5 to two feet apart and there\u2019s a lot of sun hitting the dirt in between; in other words, there\u2019s a lot of sun being wasted. That\u2019s not ideal.<\/p>\n\n\n\n Further, if you use sprinkler or drip irrigation, then you\u2019re probably wasting water between the young plants also. For example, I use drip irrigation lines whose emitters are spaced nine inches apart. If I plant my BCC 1.5 feet apart, then there is an emitter between each plant, which is watering dirt that has no roots while the BCC plants are still young.<\/p>\n\n\n\n I can do two things in order to avoid wasting water with this set up. I can handwater until the plants are big enough to access the water applied by the emitters between the plants, or I can plant something in between the BCC plants, next to those intermediate emitters.<\/p>\n\n\n\n Interplanting broccoli, cauliflower, and cabbage with lettuce<\/strong><\/p>\n\n\n\n What to plant between the BCC? Lettuce is an excellent option. It is Farmer Roy\u2019s<\/a> interplant of choice. Roy\u2019s routine is to plant romaine lettuce between all of his broccoli and cauliflower plants. Both the lettuce and broccoli or cauliflower are planted on the same day.<\/p>\n\n\n\n These two are a perfect pair because they like to grow in the same cool conditions, and the lettuce is ready for harvest long before the broccoli or cauliflower. By the time the broccoli or cauliflower leaves are massive and shading the lettuce, the lettuce has formed a nice head and is ready for harvest. From that point, the broccoli or cauliflower continues to grow and uses the water once allotted to the lettuce through the intermediate drip emitter (Roy uses drip lines with emitters that are eight inches apart).<\/p>\n\n\n\n I got great results from interplanting BCC with lettuce earlier this fall in my garden.<\/p>\n\n\n\n \u00a0<\/p>\n\n\n\n I harvested the lettuce successively over the course of a few weeks as the family needed it.<\/p>\n\n\n\n Today, the cauliflower is beginning to head up.<\/p>\n\n\n\n Interplanting BCC with cilantro and parsley<\/strong><\/p>\n\n\n\n Another couple of complementary crops to place between BCC plants are cilantro and parsley. Just as with the lettuce, you want to plant them at the same time as the BCC. And you\u2019ll start harvesting the cilantro or parsley long before the BCC leaves get so big as to shade them much.<\/p>\n\n\n\n Once the broad BCC leaves do shade them, you can harvest the whole cilantro or parsley plants. But I prefer to leave them be despite the shade, allowing them to go to flower whenever they feel ready. Bees, syrphid flies, lady bugs, and other beneficial insects enjoy cilantro and parsley flowers. Some of these insects will eat aphids, which can be a problem for broccoli, cauliflower, and cabbage plants. It\u2019s like you\u2019re cultivating natural pest control in between the BCC plants.<\/p>\n\n\n\n![\"\"](\"https:\/\/gregalder.com\/yardposts\/wp-content\/uploads\/2021\/11\/found-a-ninja-in-my-cauliflower-patch.jpg\")
