Can I grow a tree or shrub from seed?

Most people never stop to think about where trees come from. In nature almost all trees have been grown from seed. It is actually quite easy to grow most trees from seed. Some are a lot easier then others and some take a lot less time than others. 

How long does it take to grow a tree from seed?

This can be a lot faster than you might think. Every species that we offer is different but with many you can have a respectable landscape tree in less than 8-10 years. The warmer your climate the faster that you will have a large tree. 

Do I have to look after import requirements?

Some countries have import restrictions. Please contact your own customs office since we are not able to take into consideration, the lists and amendments of all countries, although we block numerous items in the shop.

We do not guarantee that your entire order can be imported. Items confiscated by customs or Ministry of Agriculture and Fishery will not be replaced by us.

It is the importer's responsibility to be aware of and to ensure compliance with the requirements of all other regulatory and advisory bodies prior to and after importation.

What is winter hardiness?

Please find the classification Z1 - 11 in our plant descriptions for your information about Winter Hardiness Zones: they give an approximate indication of the minimum temperature that a particular species can survive. Use this as a basic guideline for determining species suitable for your conditions. Other factors like soil and microclimates can influence winter hardiness to some degree.
