continental : The Rudbeckia subtomentosa needs very frequent watering; during this period of the year we advise watering even every 0-1 weeks using 1,5 litres of water, trying to keep the substratum always slightly damp.

alpine : We advise frequent watering, every 1-2 weeks using 14 litres of water, so that the soil is always a bit humid.

mediterranean : The watering must be very regular and frequent, using 16 litres of water, so that the soil is always slightly damp, avoiding excesses and water stagnation. A good rule is to wet every 0-0 weeks.

Fertilize Rudbeckia subtomentosa : In the summer let’s fertilize periodically, using a fertilizer for flowering plants, to add to the irrigating water every 10-15 days; we can otherwise use a slow release fertilizer, to spread near the plants every 3-4 months.
