Frequently Asked Questions (FAQs)

1. What fertilizer induces flowering?

If you are looking to boost flower production, you want a mix like 15-30-15, which is high in flower-developing phosphorus. If you want to green up your lawn, choose a mix like 25-6-4, which is high in nitrogen. Many fertilizers are formulated for specific plants like roses, bulbs, or vegetables.

2. Can I use lawn fertilizer in my flower garden?

No, you should not use lawn fertilizer in your garden. Lawn fertilizer has a much different nutrient profile (content and ratio of nitrogen, phosphorus, and potassium) than garden fertilizer. Lawn fertilizer may also contain herbicides or pesticides, which can harm your plants or prevent pollination by killing bees.

3. What is the best Fertiliser for lawns?

The best lawn feed (or fertiliser) to use is one that provides both protection from weeds while systematically feeding your lawn. Ideally, lawn feed should be applied between April and September with Miracle-Gro EverGreen Complete 4 in 1 providing year-round feed when applied no more than twice a year.
