How to fertilize roses

Fertilize the rose bushes in the open ground

For the roses planted on the ground , from the second year after planting, two main fertilizations can be carried out, one in the autumn period and one concentrated in the pre or post flowering phase.

Having it available, mature manure is the organic fertilizer par excellence , but manure in pellets or other organic fertilizers that can be distributed and buried in the first centimeters of soil at the base of the roses are also fine.

The second fertilization can be done with a slow release complex chemical fertilizer (those used for the garden are fine too) when the plant is in the budding phase , at the beginning of spring or wait for the blooms to finish .

It is not necessary to fertilize the plants more than once, but depending on the type of soil, exposure and type of roses, everyone will learn what will be best to choose based on how the plants grew during the previous season . (However, it is always useful not to overdo it, roses do not die of hunger, but sometimes because of too much care!)

The best fertilization , for the soil and for the plant, is the organic one in autumn . Low temperatures ensure a slow and complete degradation of the organic substance in favor of soil fertility and with the formation of humus.

With the increase of temperatures and therefore in the warmer seasons, inverse biochemical processes take place which rapidly develop mineral compounds from the stored humus.

Fertilize potted roses

For potted roses , it is recommended first of all to use containers of at least 40 cm wide and more than 50 high , universal soil and make sure it remains moist , especially in periods of extreme heat . In summer , depending on the various cases, even abundant daily wetting may be necessary. Avoid saucers .

You can choose to distribute liquid fertilizer for flowering plants in the doses indicated in the packages or slow release granular fertilizers . In any case, organic autumn fertilization is recommended and avoid fertilizing in periods of strong heat .

The potted rosebushes should be re- rooted , cleaned and the soil renewed on average every 4 years , or as soon as the plant shows suffering and difficulty in growing and blooming again.
