Since succulents are drought tolerant it’s best to ensure you’re letting the soil get bone dry in between waterings, and then give the plants a thorough soak. It’s commonly mistaken that succulents need little water but you shouldn’t be pouring just a drop when dry but rather saturate the soil completely.
During the Summer months, succulents will start to use water more quickly than before. So despite them being drought tolerant it won’t be ideal to water only every 3-4 weeks during this time since their metabolic activity is faster which means they are drinking water faster. It’ll be safe to water your succulents as soon as the soil has dried out, whether that becomes weekly or bi-weekly. Also, succulents in smaller containers will dry out faster than those in larger ones.
Winter is the time where succulents go dormant due to the diminished daylight hours and intensity of light. It’s ideal to not water succulents as frequently as during the growing season, some people don’t even water their cacti at all during Winter and they survive!
Splashing water onto the leaves can leave room for unsightly blemishes or fungal infections to develop. To avoid this, you can bottom water, use a narrow spout watering can, or wipe the leaves off after watering if water splashed onto them.
