I don't know if this will be any help but I certainly understand how the timing of the dill and the pickling cukes often, just don't come together! Would using dill seed
work for you?
The problem here is that usually the dill comes first and is fairly well spent by the time the cukes show up. The way we can have both at the same time is to cut and dry the dill. Dill is really as suitable dry as fresh for such things, IMO.
Since the flowers tend to mature at different times on the same plant you can have seed scattering about at the same time some of the flowers might even be a little too immature. Long ago, I planted "bouquet dill" to have a more manageable variety. I don't really know if it is or ever was more manageable. We must be on about the 15th generation in the garden these days, LOL!
Dill runs out of its life-cycle fairly quickly in hot weather. Bouquet dill doesn't get very tall but in cool weather, I've seen dill that gets quite a ways beyond 3' in height. Since I'm mostly relying on the volunteers and have to allow some of them to grow each year, it is especially nice that the bouquet dill doesn't start smothering the tomatoes, blocking paths and wrestling me to the ground when I try to squeeze past
Curious to know how things are working out for the original poster. BTW, catnip can be started in containers and set out fairly easily but I don't know how well it would do during the summer heat. Also, here it isn't a reliable perennial because of winter cold, I suppose. Better to let catnip do-its-own-thing and just self-sow merrily and grow pretty much wherever there can be room allowed for it.
