Recipes and Tips
Elderberries, Sambucus spp., are native to a large portion of North America. For years they have been a souce of food and beverage and also have had medicinal uses. They do grow wild in fence rows and out of the way places, but have yet to gain a good foothold for commercial produciton in the area. To that end Hearthstone Berry Farm applied for, and recieved, a small SARE (Sustainable Agriculture Research & Education) Grant to plant and monitor a trial planting of elderberries. This planting is open to anyone interested in growing elderberries. The trial planting has already exceeded its origianl plans as it now has over 14 varieties installed. Two field days will be held for persons interested in growing this native. In subsequent years several growers have come over to look at varieties and get information on planting and maintenance of elderberries.
Elderberries flower in late spring. Cross pollination is not required to produce fruit, but flowers that are cross-pollinated will produce larger fruit--it is beneficial to have two cultivars of elderberry in close proximity. New canes will produce a single cluster of fruit. Two and three year canes will produce the most fruit, with flowers borne on shoots emerging from last year's leaf axils. By year four, the productivity of the cane is reduced, so any canes over three years old are removed during winter pruning.
Fruit ripens August to September. The entire flower (called a corymb) is harvested. One method of haarvesting individual berries is to freeze the entire cluster, pull the frozen berries off, then refreeze them.
Elderberries can be purchased as bare-root plant, potted plants and even rooted or unrooted cuttings. It is important to remember that the less developed transplants will spend the first year developing a root system and will likely not produce a "first year" crop.
Plants are irrigated to 1" per week via trickle irrigation. Fertilizer applied as 19-19-19 due to low soil P levels. Rate of application is 5 ounces per first year plant and 10 ounces per second year plant (Galletta, 1994) as a split application, half at bud break and the remainder 6 weeks later.
Data collected will include size of plant, pounds of fruit, and qualitative ratings provided by field day attendees.
We would like to thank North Central USDA SARE for the grant supporting this project--benefiting growers in the entire region.
We added another 5000 square feet of production to bring us up to just under 1/2 acre of elderberries. The plants added were from Mulberry Creek herb farm. This section berries, all one type, is going to be used to test out althernative methods of pruning, fertilizing and weed control--they all have to be the same variety for a valid comparison. We are also doing some propagating to fill in gaps in the earleir block where plants were trial plants were lost.
Most of the berries came through our deep freeze without a problem except for 'Haschburg', one of the S. nigra varieteis. Several of the plants budded out then collaped within a few weeks.
Rainfall was good again this year. We did not run irrigation once for the elderberries. Some of the excessive rain events interfered with our herbicides and we lost control of the weeds in some rows.
Harvest, as expected, was even better this year.
Rainfall was much better this year as we had significant rain with good drying time in between. We ran the irrigation infrequently this year. The weeds are our biggest problem. Elderberries don't like competition and where we can control the weeds, the plants grow much more vigorously. We are planning on using mulch to cut back on our need for herbicides, but that is a very labor intensive and expensive plan.
This was the first year we had to do any real pruining. Elderberries bear poorly on any canes over three years old. Now that our planting is mature, we did a lot of pruning to keep the bushes to a total of 24 canes and also to prune out the 4 year old wood.
After an early start with temperatures reaching 80 in late March, freezing temperatures returned for much of April. Freeze and frost damage to apples and peaches in the area left the elderberries unharmed. Elderberries flowers are terminal on the current year's growth so flower buds were produced after the March heat and April freeze.
Late spring and summer brought little to no rain to Nova, Ohio. The drought of 2012 was the worst in three decades. Rainfall records on the farm show that the farm missed all of the mid-summer thunderstorms. The pond, ten feet deep, was pumped to within four feet of the bottom. As water reserves in the soil profile were depleted (in August) the single drip irrigation line was not able to delever enough water to the plants. A second line for each row will be added in the coming year(s).
S. racemosa aborted all of its fruit during a stretch of 90 degree weather. S. nigra held up the best late in the drought.
The bird netting system was finished this year. Keeping the birds out made a huge difference to the poor drought harvest. Fruit clusters were full and picked when 100% ripe. Pickers were able to fill boxes from one shrub.
Fertilizer was reapplied at half the recommended rate. Scent and taste repellents for deer failed in June (I suspect we had at least one mother and fawn in the hay field just behind the elderberry block). The plants continued to grow but many buds were lost. Bird netting was laid over plants for deer control!
Weed control was from a combination of hand-weeding, careful use of glyphosate, and Poast/Surflan tank mix applied mid spring for grassy weeds and pre-emergent. Extremely heavy rain drastically shortened the efficacy of pre-emergents across the area in nurseries, landscapes and orchards. A flush of weed growth followed in unmulched areas--the mulch was great help. Spot treatment with glyphosate was usd in areas between plants.
Japanese beetle was only a minor problem this year. Occasional rain late July and early August may lead to increased beetle activity in 2012; this will be considered when planning pest control next year.
Rain has been "feast or famine" as record spring rains were followed by several weeks with no rain, followed by a three inch rain, followed by two weeks with no rain.... Irrigation was run to apply a total of one to two inches of water per week (the half-acre pond had been pumped down by twelve inches by August). On October 21st, our area broke the all time record for yearly rainfall (with two months left in the year).
