seed embedding depth - 1-1.5 cm.

The seeding rate is 1.5-2 g per sq.m.

Attention! Do not sow seeds very densely, as thickened plantings will prevent the root crop from gaining the desired size and can lead to darting.

The minimum temperature of seed germination is +2 +4 C, seedlings can withstand freezing up to -3 C, but prolonged low temperatures lead to rifling. The optimum temperature for the formation of root crops is +15 +20 C.

Radish Rudolph F1 negatively reacts to excessive nitrogen fertilizer, from its overabundance of root crops flabby and lose their rounded shape.

It should be noted that radish responds well to the introduction of ash under digging (especially on acidic soils).

Further care of crops consists in timely thinning (with dense shoots), mandatory watering, loosening and weeding.
