FertilizingFertilizer can help your plants get the nutrients they need and contribute to lush growth. Since plants are fed frequently during the growing stage, wait at least two months before feeding your plants once you take them home. After that fertilize no more than once a month.
As a general rule, always water your plants one day before fertilizing. Never fertilize when the soil is very dry. In dry soil, granulated fertilizers will not absorb and liquid fertilizers can burn dry roots.
What to Look For
The best fertilizers are those that have their nitrogen, phosphorus and potassium in a 1-2-1 ratio; a fertilizer marked 5-10-5 or 10-20-10 on the package, for example, is ideal. The reason for a 1-2-1 ratio is that it contains ample phosphorus, which promotes sturdy cell growth, but not so much nitrogen, which makes for fast leaf growth, or potassium, which also stimulates plant development. Follow the directions on the label and under no circumstances make the mixture stronger than the one suggested by the manufacturer.
