Crataegus mollis is a very hardy plant, tolerating temperatures down to at least -18°c[1]. Crataegus species are generally very easily cultivated plants, growing best in full sun to medium shade and preferring a well-drained but moisture retentive loamy soil, though they are not usually fussy[2, 3]. This species grows well on a chalk soil and also in heavy clay soils[3]. Once established, many species can tolerate a range of difficult conditions including drought; excessively moist soils; exposed, windy, maritime conditions; and atmospheric pollution[3]. Notes on the plants habitat above may give more ideas on this[PFAF]. Trees growing in a sunny position generally produce more and better quality fruit than trees growing in the shade[PFAF]. The tree is occasionally cultivated on a garden basis, mainly within its native range, for its edible fruit[4]. A very ornamental plant[2], the branches of some forms are almost thornless[5]. A rather variable species, it has been separated into several different species by some botanists[6]. This species is much confused with Crataegus chrysocarpa[2] and with Crataegus coccinea[7]. Crataegus species often hybridize freely with other members of the genus[2, 3]. This statement is not fully accurate; at least in the wild most Crataegus species usually breed true and only occasionally hybridize - in addition, any hybrids are usually putative[8]. Many Crataegus species are very variable with regard to fruit size and quality. Seedlings, even if obtained from a good fruiting form, can often be disappointing - though they can also be an improvement on the original form. The most reliable way of obtaining a good fruiting form is by grafting from a known good tree, or obtaining a named cultivar from a reliable source[PFAF]. Seedling trees take from 5 - 8 years before they start bearing fruit, though grafted trees will often flower heavily in their third year[PFAF]. Seedlings should not be left in a seedbed for more than 2 years without being transplanted[2]. The flowers have a foetid smell somewhat like decaying fish. This attracts midges which are the main means of fertilization. When freshly open, the flowers have more pleasant scent with balsamic undertones[9]. Crataegus arnoldiana is a tree with an excellent potential as a fruit crop in Britain. The fruit is of very good quality and is freely borne, whilst the tree is of very easy cultivation and rarely troubled by pests or diseases[PFAF]. A tree at the Hillier Arboretum in September 1993 was about 3 metres tall and 1.5 metres wide. The growth looked somewhat weak and the tree was leaning due to wind rock but it was carrying a heavy crop of fruit[PFAF].

Propagation

Seed - this is best sown as soon as it is ripe in the autumn in a cold frame, some of the seed will germinate in the spring, though most will probably take another year. Stored seed can be very slow and erratic to germinate, it should be warm stratified for 3 months at 15°c and then cold stratified for another 3 months at 4°c[10]. It may still take another 18 months to germinate[11]. Scarifying the seed before stratifying it might reduce this time[12]. Fermenting the seed for a few days in its own pulp may also speed up the germination process[PFAF]. Another possibility is to harvest the seed 'green' (as soon as the embryo has fully developed but before the seedcoat hardens) and sow it immediately in a cold frame. If timed well, it can germinate in the spring[12]. If you are only growing small quantities of plants, it is best to pot up the seedlings as soon as they are large enough to handle and grow them on in individual pots for their first year, planting them out in late spring into nursery beds or their final positions. When growing larger quantities, it might be best to sow them directly outdoors in a seedbed, but with protection from mice and other seed-eating creatures. Grow them on in the seedbed until large enough to plant out, but undercut the roots if they are to be left undisturbed for more than two years.
