Liquid Seaweed Fertiliser

Question

Hi, I have planted a blackberry(from a 3L pot) one week ago. A small bay and a rosemary which I planted 2 weeks ago. They are fairly well established. Can I feed them with liquid seaweed fertiliser now or do I have to wait?

Answer 1

If a soil sample reveals that nutrients are lacking, or you see signs of deficiency, then yes. If not, then it would not be wise to feed. Always test levels if you are uncertain.
