Synopsis- In our second lab of the semester we potted up 4 cultivars of ferns, ‘Boston Junior’, ‘Emerald Vase’, ‘Southern Maidenhair’, and ‘Rosy Maidenhair’, in 5″ pots with one plug per pot and two pots per cultivar. We also potted up two 14″ pots with five cultivars of snapdragons, ‘Potomac Appleblossom’, ‘Cherry Rose’, ‘Early Orange’, ‘Early Pink’, and ‘Early Rose’ with two plugs each per pot.
The instructors also demonstrated Easter Lily leaf counting to see how many leaves must unfold for the Lily to be on track for flowering. To determine this you must count all the leaves yet to unfold and divide this number by the number of days until VB. You must also determine what rate the existing unfolded leaves unfolded per day. This can be solved by counting all the unfolded leaves and dividing that number by the number of days from emergence of first leaves to now. If the rate is lower than the number needed to unfold than precautionary measures need to be taken to ensure that plants are ready to bloom by Easter.
Pests- This lab was the first lab that we observed our sticky cards for insects. There was only one insect observed on my card which happened to be a fungus gnat.
Nutrition- EC/pH readings were taken for the ‘Sophie Ivy Geranium’ and the ‘ Easter lily’. For the Easter Lily a total of three readings were taken for each pot. The average EC was 1.56 and the average pH was 5.73. Two readings were taken for the ivy geraniums. The average EC reading was 2.7 and the average pH was 6.5. No corrective actions were taken as of yet.
Growth- Each cultivar was measured for height x width to compare subsequent growth. Measurements for the ferns are as follows: ‘Boston Junior’ 10cm x 15cm, ‘Emerald Case’ 11cm x 11cm, ‘Southern Maidenhair’ 8cm x 9cm, and ‘Rosy Maidenhair’ 4cm x 14cm. The snapdragon measurement is as follows with a combined measurment of each cultivar in one pot: 8cm x 31cm.
Second measurements were taken for the plants we potted up last week. The Easter Lily had a measurment of 25cm x 23cm with an 8cm x 3cm increase in growth. The geranium cultivars ‘Tango’ had a measurement of 10cm x 15cm with a 4cm increase in width, while ‘Avendia’ had a measurement of 13cm x 19cm with a 4cm increase in width. The Ivy geranium had a measurment of 11cm x 36cm with a 4cm increase in width. The two mum cultivars; ‘Roanoke’ had a measurement of 13cm x 27cm with a 2cm increase in width, while the ‘Miramar’ had a measurement of 10cm x 19cm with an increase of 2cm in height.
Cultural Treatments- We placed tomato cages over the two pots of snapdragons to help support the tall nature of the plants. We also disbudded and removed dead leaves all of the geraniums to increase growth.
