My gladioli were growing beautifully but as the flower head was appearing they developed holes and eventually fell of before they could open, the leaves were like lace with all the holes eaten into them. Now the grubs have shown themselves. I have cut them right down, washed the soil of the roots also I have lots of baby bulbs with roots and have washed those also.
The question is what is the best way to winter the large bulbs and also the baby ones and how can I treat the soil to get rid of these grubs. This my first time with gladioli .
