Cold temperatures lead to bottom leaf yellowing, slow growth, basal stem and root rots. Avoid over-watering the young transplants, especially in large patios and baskets. Apply a preventative fungicide drench if needed to prevent fungal root diseases. Scout and treat for thrips.

Tech Tips: Calypso Bacopa should be pinched during propagation, which results in a well-branched, mounded plug. Avoid keeping plants too wet and cold early on after transplant, which can result in root rot and tip chlorosis (iron deficiency), especially in large baskets and containers. High DLIs and cool finishing temperatures produce high-quality bacopa. Plants can be pinched twice for baskets and large containers, which results in full, uniform plants. Monitor media pH and EC closely and avoid high EC levels to prevent damage roots. Do not let plants get extremely dry which results in necrotic foliage and root loss. Calypso Bacopa has moderate vigor and will generally need a plant growth regulator (PGR) treatment in propagation. To control growth after rooting, a spray of B-Nine ® WSG (1,500 ppm) is sufficient. It is also becoming popular for growers to combine Florel ® (200 ppm) with the B-Nine ® WSG (1,500 ppm) to increase growth control and to improve branching. These Florel ® + B-Nine ® WSG combo sprays should be applied to actively growing plants. Do not spray B-Nine ® WSG or Florel ® + B-Nine ® WSG tank mixes on stressed or weak cuttings. For all sprays listed above, the mist should be off for a minimum of one hour for the PGR to absorb into the leaf tissue.
