How often should I water my bonsai?

How frequently you water your bonsai depends on many things. A dry wind, excessive heat, or a combination of both, can quickly dry out the soil, so you must monitor moisture levels regularly. Generally if you keep your trees outside where rain can water them, you don't need to worry much in the winter except in times of hot weather or little rain. In the summer you should endeavour to water your plants several times a week, and daily in very hot periods - where you should move the trees into the shade. You may find it is a good idea to set up a drip sprinkler system - where the bonsai are watered every day in the summer and every three days in the winter. Alternatively, you can use a watering can with a fine rose attached to water the soil and roots. Using a general water sprayer to increase humidity is also a good idea if your climate experiences dry periods.
