I'm a beginner in gardening, and I have two questions:
How can I get rid of the soil on the top of plants?
I want to plant this small tree in the vase, waht should I do to prevent the soil and water from leaking?
1. stand the pot (vase) on a large saucer to catch any water that drains from the pot.
2. lightly brush the soil off the leaves with your hands. When planting, I think you will find that some soil or compost will always get onto some of the leaves!! You can't be pristine when gardening I'm afraid.
Have a look at some of the demonstrations etc on this link http://www.gardenersworld.com/article-search/?searchterm=potting-up
It'll give you the information you need.
Good luck and welcome to gardening
Thank you, yes it's impossible to be pristine
Use a watering can and water the soil off the leaves. Some plants - of a robust nature - can be put under a cold shower to clean them. Outside plants will be kept clean by the rain.
