Smaller mice would get through 1/2" mesh here.

Many winter growing species do not like to be so dry, with there being both
a negligable summer rain fall and the beds raised and in full sun you may
find some plants prefer to be moister or shaded, -the "indicator" dicots
are fairly drought resistant ones.'Bulbs' do tend to pull themselves to a
depth where the moisture is to their liking though.

Unless you plan to create a 'peat bed' or 'high humus bed' which might grow
many lovely plants such as Anemonella, Crocus banaticus, Iris
winowgradowii, Trilliums, Lillies, 50% humus is very high for ground grown
plants. Probably good for the summer growers though. Small volumes of soil
dry out which is why humus is important in pots.

My mix you refer to for growing bulbs in pots was 50% AGGREGATE (sand and
grit) to 50% soil,  and to which I add organic material for various plants.
