Best grown in deep, loamy, moderately fertile, slightly acidic, medium moisture, well-drained soils in full sun. Tolerates average garden soils, but unamended heavy clay soils which waterlog easily and drain poorly should be avoided. Generally, the more dwarfing the rootstock, the greater the need for soil fertility. Needs full sun for maximum flower and fruit production. More than one variety must be planted in order to facilitate best pollination and subsequent fruit production.

Malus is a genus of about 35 species of deciduous trees and shrubs from Europe, Asia and North America. Some eating apples are hybrids but others are attributed to M. domestica or M. pumila.
Edible apple cultivars do not grow particularly well on their own roots. As a result, apple varieties sold in commerce today have all been grafted onto rootstocks which, inter alia, control the size of the tree. Rootstocks are generally classified as follows (tree height in parenthesis): dwarf (8-10'), semi-dwarf (12-15') and standard (18-25' or more). All trees bear full-size fruit, however. Most trees sold today for the home apple grower are grafted onto dwarfing rootstocks (dwarf or semi-dwarf), resulting in trees which, in comparison to standard trees, are (1) easier to manage (spray, prune and harvest) and (2) produce fruit at an earlier age.
Genus name from Latin is an ancient name for apple.
‘Grimes Golden’ is an old eating apple that was first discovered by Thomas Grimes growing in West Virginia in the early 1800s. It is believed to be a parent of the popular golden delicious apple. White blossoms appear in early spring, followed by medium to large yellow apples with a tart and spicy but sweet taste. Apples ripen in September to October. ‘Golden Grimes’ is considered to be useful for most culinary purposes, except perhaps baking. Serrated dark green leaves.
‘Grimes Golden’ shows some resistance to cedar apple rust, apple scab, fire blight and powdery mildew. Susceptible to collar rot. Potential insect pests include aphids, maggots, codling moth and plum curculio. Spider mites can also be a problem. Regardless of disease resistance levels, good cultural practices are always essential and some chemical spraying may become necessary in order to control pests.
‘Grimes Golden’ is pruned and grown primarily with a view toward producing quality fruit, and its ornamental features are usually considered secondary. It should be grouped in a sunny location with other apple varieties. Spring apple blossoms and fall fruit do, of course, add color and interest to the landscape.
