I'm both new to bonsais and this forum, and i'm looking for some basic care tips for my newly acquired Trident Maple bonsai that me and my girlfriend have bought. We are really excited about our tree but are somewhat confused about a few things, mainly watering though.
I have looked around the net for suggestions on how often, how much and the method with which to keep our little friend hydrated enough to thrive but not so much as to develop root rot etc etc.
However there are so many contradictions and confusing suggestions, i'm hoping that someone here may be able to give me some more straight answers to the following questions:
-what tool should we be using to water? a hose? watering can? spray bottle? with a tap? submerging underwater?
-how does watering vary in each season? obviously summer requires more than winter but how much? i'd like something more than the 'don't over water in winter, don't let it dry out in summer' response i see all over the net
-when do we water? we have figured out that our bonsai must remain damp, not soaked/wet, and to only water when the soil is anything less than damp. I am more curious as to finding a method with which to test the dryness of the soil/plant if possible or a way to determine where 'damp' becomes 'dry'
-any other helpful suggestions for a bonsai 'noob' i.e. pruning, how to encourage growth both in foliage and for a strong thick trunk, when to give fertilizer, whether of not moss is a good idea etc etc.
Some of these things may seem obvious to some people but we are both very new to bonsais and indeed gardening on the whole. The reason we would love to learn more about these things in a more in depth and succinct manner is because we have already become very attached to the little fella after only a few days of ownership (purchased him only 2 days ago) even naming him Leonardo....because, well, its an awesome name.
I am well aware some of the questions i have asked probably HAVE been addressed in other posts on the forum or sites on the net, but we really just would like straight answers that relate as much as possible to our specific bonsai.
I have provided a picture below as well as pot/ plant dimensions:
Trident Maple
Height: 38 cm
Pot Width: 16cm
Pot Length: 19cm
(dimensions are approximate)

Thank you very much anyone who is able to give a response to any of my queries.
Kind Regards,
Luis
