I'm in the Netherlands, I have two Otto Luyken Cherry Laurels planted in large pots with drainage holes. I've had them about one month. This is my first ever gardening attempt, I planted them just with basic soil and topped with mulch. I have given liquid plant food once per week. The plants were doing well and flowering beautifully until about one week ago, when the flowers started to turn brown and fall off when lightly touched. This week we experienced a significant temperature drop along with several days of heavy rain and wind, so the plants are pretty much flowerless right now.
The plant itself still looks strong, I examined the leaves and 95% look nice and green. I found a few yellow leaves down at the base of the plant.
From what I've found online, the problems could be due to chlorosis or overwatering? If overwatered, then would a few days of dryness help balance things out, or do I need to intervene some other way? I suppose I also need to get a kit to check the pH?
For the areas that have lost all of the flowers, is there any hope to get more flowering this spring? Is there any sort of pruning I should do to encourage new growth?
Thanks for any input or advice!
