Dahlia

‘Dahlinova Hypnotica Bronze Bicolor’ and ‘Dahlinova Hypnotica White’ are two new varieties in this large-flowered uniform series. They boast good branching and a vigorous plant habit.

Plant unrooted cuttings deep at least up to the first set of leaves. Keep plants well misted until root initials appear. Rooting temperature should be about 70° F, and average rooting time is three weeks.

Growing mix should be well drained with sufficient moisture retention to prevent daily wilting. Optimum pH is 5.8-6.2. Thoroughly moisten growing mix with each irrigation or fertigation. Allow plants to dry slightly between irrigations. Do not over water. Do not allow plants to wilt or leaf margin can occur.

Good crop growth is obtained with 200- to 250-ppm nitrogen fertigation from a complete N-P-K water-soluble fertilizer. The majority of nitrogen should be in the nitrate form. Avoid high ammonia or urea fertilizers, which can reduce plant quality by encouraging soft, stretched growth. Crop time is seven to nine weeks.
