Blueberry Bush Calculator
Blueberry harvest pounds and jam share from bush count.
What it does
Blueberries pay patience. Mature bushes pour gallons each summer for decades once acid soil and varieties settle.
The tool above multiplies bushes by eight pounds. Six bushes give 48 lb with 24 lb for jam. The metric match is 22 kg with 10.9 kg.
Eight pounds fits mature northern highbush. Young plants trickle for three years, then climb with pruning and mulch.
Jam takes half in this plan. Fresh eating claims the rest, with freezing smoothing glut weeks.
Acid soil rules. Tests near 4.5 to 5.5 suit berries, with sulfur lowering high readings before planting.
How to use
- Enter bush count: 6 suits a family row.

Worked example
Example: 6 bushes
Defaults: 6 bushes. These are also the default values, so the page opens on this answer.
- Bushes: 6 mature northern highbush.
- Each: 8 lb per bush.
- Harvest: 6 x 8 = 48 lb.
- Jam share: 48 / 2 = 24 lb for jam.
- Tool shows 48 lb harvest, 8 lb per bush, 24 lb jam berries.

| 6 | 48 lb | 24 lb |
| 10 | 80 lb | 40 lb |
| 12 | 96 lb | 48 lb |
Limits
- Yield guide only. Variety rules harvest.
- Young bushes trail mature ones.
- Birds take un-netted crops.
- Soil pH gates everything.
Common mistakes
- Alkaline soil with no test.
- One variety with poor set.
- No nets, feeding birds.
- Skipping pruning for years.
- Picking underripe for jam.

Questions
Harvest from 6 bushes?
Multiply bushes by 8 lb. Here 6 x 8 = 48 lb.
Yield per bush?
Near 8 lb (3.6 kg) per mature bush in this plan. Young bushes trail for years.
Jam share?
Half the harvest suits jam with fresh eating the rest. Here 48 / 2 = 24 lb.
Soil pH?
Acid soil near pH 4.5 to 5.5 with sulfur help when tests read high.
One variety enough?
Yes. Two varieties cross pollinate bigger crops.
Netting needed?
No. Birds claim un-netted bushes fast.
