As seasoned horticulturists know, applying nitrogen fertilizers in spring is a proven practice to fuel growth. With many options available, select those best suited for newly planted or established garden plants.
From April through September, top choices include dried blood, prized for its high nitrogen content; guano, offering nitrogen plus phosphorus to enhance rooting; and fertilizers made from algae and fish waste. Time nitrogen applications for active growth periods in early spring and/or post-summer. Skip it during flowering or fruiting to avoid issues like flower drop or poor fruit set.
Stick to recommended rates—overdoing nitrogen heightens disease and aphid risks, while vegetables can build up unhealthy nitrate levels.
Plant manures, like nettle and comfrey, excel as natural growth boosters.
