Fertilize, But Don't Over-Fertilize!
As soon as the first green seedlings peek out from the soil, do you feel the urge to start fertilising?
Germinated seedlings need to be allowed to grow sufficiently, ideally to the stage of 2-4 true leaves. However, the larger they are, the greater their nutrient requirements. For most plants, carry out the first fertilisation only after the first or second transplanting in the so-called growth phase. The growth phase is the period during which plants develop stems, branches, leaves and other green plant matter.
What's needed?
During the growth period, plants need mainly nitrogen, phosphorus and potassium. If they lack any of these elements during growth, they will start to turn yellow. Nitrogen promotes the growth of green matter, phosphorus is essential for roots, flower formation and overall plant health, whilst potassium supports flowering and fruit ripening and increases plant resistance to pests.
Roots
Small seedlings usually have weak roots. You can solve this problem with a root stimulator. Simply put – such a stimulator gives your seedlings a real boost! A root stimulator promotes plant growth, helps with resistance, revitalises and supports the micro-organic environment in the substrate. In short, it gives them everything they need for proper growth. But be careful not to use it with liquid fertiliser, as this reduces its effectiveness!
It works best with watering
You can fertilise with compost more extensively throughout the growing season, as nitrogen is released gradually from it and plants take what they need. However, it's not suitable for quick-growing vegetables. The best and fastest way to fertilise is together with watering. You can choose from granulated or liquid fertilisers that can be mixed with water. You can use either special fertilisers designed specifically for a particular type of plant or vegetable, or get a universal one that suits everyone! When applying fertilisers, always follow the recommended concentration to avoid doing more harm than good to your vegetables.
What not to forget?
- Not all plants tolerate chlorine-based fertilisers! For fertilising plants sensitive to chlorine, you can use potassium-based fertilisers or buy special ones that don't contain chlorine.
- More doesn't mean better. It's always better to stick to the doses prescribed by the manufacturer.
- When foliar feeding, be careful not to damage the plants! Don't forget to follow the concentrations according to the instructions.
