Hi.. I have planted 5 gladiolus bulbs in a large container with good drainage. And have popped a dahlia slap bang in the centre.. The plants are doing OK but I wonder if I've overdone it and crowded the situation a bit.. The glads are nearly 2 feet tall and the tall sharp leaves are starting to bend... And the dahlia is also around 2 foot tall and has already got lots of bids on it... I am feeding tomorite half strength once a week... Are my glads going to eventually flower or are they late.. Have I overcrowded the pot? And what would be a good food for them?
