pH range of 4.8 to 5.2.
3 parts potting soil, 1 part perlite and 1 part pine bark for light, quick-draining, nourishing soil.
OR: 40% peat moss and 10% compost, then the remaining native soil should make up the last 50%.
IMPORTANT NOTE! Do not use mushroom compost or composted manure in soil used for blueberries. It will likely kill your plants due to the high nitrogen content. If you are unsure as to whether or not your compost is suitable for blueberries, leave it out.
Southern Highbush (USDA hardiness zones 5-10) Blueberries have wide, shallow root systems. Place a bare root or a transplant into a 5-10 gallon container. After a couple of years, shift up to a wider container, such as a half wine barrel.( 25 gal. or more)
Emerald
“Emerald” Southern Highbush Blueberry Plants are 2 1/4 inch potted plants with at least a two inch root system and are at least 3-5 inches tall.
Most all edible plants grow well in Full Sun but a little shade won’t hurt. Blueberry Plants need to be planted in acidic soil/low pH 5.5-6.4. A recommend 60%-80% Pine Mulch/20-40% Peat.
4 inch pot for starter plants then re-pot to 25 Gal.pot or plant in ground.
The plant is moderate grower and nice and bushy. On average the plant is more disease resistant than most Southern Highbush Plants.
It is low chill 50-200 hours and has high evergreen qualities which means it’s almost NO CHILL or can be grown past zone 9. It is mid to late season producer with a harvest of over 6 weeks. The berries are large.
Blueberry bushes like very acidic soil, and a pH level between 4.0 to 4.8 not over 6. is required for the plants to absorb water and nutrients and produce berries.
Roots go 2 feet deep; plant in rich soil.
Water slowly, deeply, and infrequently. During the summer, water every 7 to 10 days.
Fertilize mature grapes in February and May. Ammonium sulfateis the most commonly recommended blueberry fertilizer for ensuring the pH of the soil remains acidic.
How much to initially apply depends, of course, on how acidic your soil is to begin with.
Typically, 2 to 4 ounces per bush per year is adequate to maintain an established pH between 4.5 and 5.1.
