Ulmus americana (American Elm) seeds

£1.60

The American Elm is a very old species with an attractive form with a vase shaped, rounded crown.  Once very popular as a street and park tree in the US, but numbers have been decimated by Dutch Elm disease.  We recommend growing as a Bonsai tree as it is robust, fast growing and easy to maintain.

Hardy Tree
Height: to 24m if left to grow, any size as Bonsai
Position: Sun or semi shade

Packet of 30 seeds

 


GROWING GUIDE

Sowing Instructions: Sow at any time of the year. Mix equal parts of seed compost with vermiculite, perlite or horticultural grit and sow seeds very thinly on the surface, then just cover them with a layer of compost, vermiculite or perlite. Seal inside a polythene bag and place in the fridge for 2 months. After this, move to a propagator or other warm place and maintain an optimum temperature of 18-21C. Germination should take place within 1-3 months. Note: Germination can be very erratic, so sow thinly and prick out the seedlings as they become large enough to handle disturbing the rest of the compost as little as possible.

An alternative method is to sow in pots as above during late summer to early winter then place in a cold frame and let nature take its course as the seasons change with the seedlings emerging the next spring.


Growing Instructions: Transplant seedlings when large enough to handle into 7.5cm pots and grow on in a cold frame or nursery bed for a year or two then plant out in a sunny or semi shaded position.
