Im afraid like a proper ignorant gardener i went and bought a bonsai tree for my parents for their wedding anniversary. was dubious in the shop about the little thing it looked a bit yellow but i liked its shape so i gave it a home. its a 16 year old serissa
leaves became nice and green on my mantlepiece in my sitting room. not in direct sunlight at all. room is warm due to double glazing windows. splashed a bit of water on it when the soil started looking dry.
Gave plant to parent-two weeks later its back with me clearly ill. yellow leaves..
Chances are its going to die-ive read the stickys and done some rooting around on other sites and know this variety is finnicky
EDITED: to say that actually there are two holes in the bottom of its pot but the soil i can see from underneath looks a little dry. ought i be filling the overflow bowl with water? oh dear i think this is the chinese three watering technique i don't really follow...
soil has moss on it-good or bad
soil is quite hard ie difficult to stick a pin into-doesnt look particulary rich-ought i give it compost or something
its probably been overwatered-the pot its in has no holes anywhere should it? ie for drainage?
i will take pics with digital camera and upload if it will help
thanks for any replies and apologies for being another amateur killing a beautiful tree
