A watering tip made of porous clay makes watering easier.
You can connect e.g. a wine bottle to the watering tip. The water slowly seeps through the clay to make it available to the plant's root system.
The plants stay alive during the cabin or holiday trip.
Use the tip to make a hole in the soil. Fill the bottle and put the watering tip upside down in the mouth of the bottle. Turn upside down and press into the hole in the soil.
When the plant has used up the water, refill the bottle.
The water usually runs out of the bottle in about 3-5 days.
