How to fertilize conifers in the fall?
We start fertilizing conifers in August , when the plants slowly prepare for winter. Conifers do not need nitrogen fertilizers in this period, but autumn fertilizers for conifers specially tailored to their needs.Fertilize conifers until October, in accordance with the recommendations of the fertilizer manufacturer and in the amount specified on the packagingThe fertilizer should be evenly spread over the surface of the earth corresponding to the diameter of the crown, mixing it with the substrate if possible, and then watering it abundantly. In the case of columnar plants, we cover the fertilizer on an area twice as large as the diameter of the crown.
What to fertilize conifers in the fall?
In autumn we fertilize coniferswith special autumn fertilizers for conifers, in granular or liquid form.

Fall fertilizers for conifers
In the case ofautumn liquid fertilizers for conifersapply the dose according to the manufacturer's recommendations. Usually for young plants we dilute 10-20 ml of fertilizer in a liter of water, while for older plants (over 4 years) we dilute 20-30 ml of fertilizer in a liter of water. We use liquid fertilizer every 7-14 days.Fertilization of conifers in the autumn with granulated fertilizersis carried out twice, at intervals of 4-6 weeks. Depending on the age and size of conifers, we use 15 g of fertilizer per 1 meter of tree or shrub height.
Good to know!
Instead of ready-made autumn fertilizer mixtures for conifers, we can use simpler and much cheaper phosphorus and potassium fertilizers. When deciding on such a solution, it is worth reaching for e.g. potassium sulphate, which, apart from the potassium needed in autumn, also contains sulfur, contributing to the acidification of the soil, which is very beneficial for conifers.
Apart from autumn mineral fertilizers for conifers, we can also use compost in this period. This valuable natural organic fertilizer improves the structure of the soil, enriches it with humus necessary for conifers and can also be used as a mulch to protect plants against frost.
