Hello - I have a few questions for you related to fertilizing: 1) I recently had the soil in my backyard vegetable boxes tested and I want to amend the soil according to their recommendations before I plant/seed this year's crop. This is the first time that some of the boxes are testing low in Boron (0.2 - 0.3ppm). I read in one of your publications that you can add 1 tbsp Borax in 1 gallon of water and apply to 100 sq ft - do I need to wait any amount of time after that application before safely planting/seeding? 2) The soil testing suggests adding some sulfur (SO4-S) to avoid plant yellowing and lack of vigor. Which type of S product should I use? What should I look for on the label? 3) I also need to add N and was planning on adding feather meal. Because it is slow acting, should I apply some other form of N at planting time? If yes, which is preferred - blood meal or ammonium sulfate and at what rate? 4) I fertilized my blueberry bushes two months ago with an organic fertilizer for acid-loving plants. Can I test that soil now, or do I need to wait a certain amount of time longer? Some of my bushes are not doing well and I want to make sure everything is in the right range. Thank you for your help!!! Anne
