A short stratification of 6 weeks at 4°c can improve the germination of stored seed. • Plant seedlings out into their permanent positions as soon as possible. Protect them for their first winter or two. Pinus radiata plants have a very sparse root system and the sooner they are planted into their permanent positions, the better they will grow. • Plant out. The trees should be planted into their permanent positions when they are quite small, between 30 and 90cm. It is common enough to plant them out when they are about 5 – 10cm tall. So long as th
