Neal, no I don't dig all of the Globemasters each year, but I have dug some of them up and divided them to check on their health and how large the bulbs have grown.
What can I say, I'm curious! Those that were divided every year was much larger than those that were left to form a clump.
I haven't stored them dry over the summer and I don't think it's necessary here. However the soil here is pure sand on a slope and we have some 25 feet down to the ground water and also very mature pine trees sucking up all extra moisture. Even in a heavily amended garden bed it never gets particularly wet in most places. That said I have grown Globemaster in a spot that is pretty dry, even for my conditions. This year I have planted a few where they will get a bit more moisture and I will see how that goes. Storing them dry over summer or perhaps in dry sand would for sure be a great idea if one was unsure over the local conditions!!!
This year I have had Allium Ambassador in the garden and despite being planted in the driest, most sunlit area I have, I noticed some rot on some of them when digging and dividing in early September. This could be the heritage from Allium giganteum which supposedly is a bit sensitive to summer moisture, or it could have been something that have been nibbling on the bulbs and introduced rot. Some union flies and other pests can supposedly attack ornamental unions as well, so it can be good to be aware of this possibility. If they survive to next year, I plan to lift them for summer
Before the deer invasion we let the tougher tulip types (darwin hybrids and Tulipa tarda was the best) naturalise here and they did very well without lifting, growing and multiplying every year as the soil is so well drained. They even sawed themself around to a small extent. One thing to watch out for in our climate is Botrytis blight and looking back I suspect that this was what really killed the less vigorous tulips here, not summer moisture. Summer lifting and discarding suspicious bulbs helps control this as they are replanted in fresh soil, free of sclerotia infected debris. Also of course many tulips are bred specifically to multiply and this is the best for the tulip grower who wants to sell his crop, but for us trying to have them in the garden it's not ideal as all we get is a lot of leaves, but no bloom, as the tulips breaks up in many small bulbs!!!
With annual lifting I noticed that some of the old fashioned large Darwin hybrids produce very big bulbs, 16cm+, on a regular basis, so no wonder they are survivors. This however hasn't been true for van Eijk (a small Darwin hybrid) that is prone to breaking up in small bulbs here (it could be excellent in other conditions for all I know) .
