Propagating blueberries

in #nature4 years ago

Blueberry propagation is relatively easy and gives good results, but it takes at least a year to get a well rooted plant that can be planted to it’s final location.

Blueberries are usually propagated from softwood or hardwood cuttings by cutting twigs from healthy mother plants. Cuttings are then placed into soil, that holds moisture well and allows adequate aeration. Drainage is extremely important and in most cases cuttings fail to root, because of waterlogged soil which causes young fragile roots to rot. Softwood cuttings are usually taken during the late spring or early summer. Hardwood cuttings, on the other hand, can be obtained during winter dormancy in January or February in northern hemisphere.


Hardwood cuttings usually give better results than softwood cuttings, which are more delicate, can easily dessicate and are more susceptible to fungal infections and rot. To take hardwood cuttings, one year old shoots are used. It’s essential that the cuttings don’t have flower buds, if they do, you need to cut off the top part of the shoot. Flowers make rooting almost impossible, because they deplete the energy of the cutting faster than new roots can grow. Cuttings need to be 10 to 12 cm long. Bottom part of each cutting needs to be severed, to promote root growth. By peeling of 1 cm of bark on one side of the cutting should be enough. Place the cuttings into the soil so that the peeled bark ends up on the bottom in the substrate. You need to stick at least half of the cutting below soil level and only one or two leaf buds above the soil.

Soil needs to be acidic with pH ranging from 4.5 to 5 and slightly moist. Good drainage is essential. At first, without the leaves, water consumption will be minimal, so water the cuttings accordingly. When the leaves start growing, they need a bit more water and can use occasional misting. In case of misting, good ventilation is essential to prevent fungal infections. In early summer, blueberry cuttings should start growing faster. Faster growth indicates that the roots have started growing and that the plants started to use new source of nutrients. At that point, blueberries can start receiving their fertilizer. At first, I rather use half strength solution of water soluble fertilizer. If the plants don’t complain, I up the dosage according to instructions on the label.

In a couple of months, cuttings form callus around the wounded tissue and it doesn’t take long before first roots appear and the cuttings take off. The roots are fragile in the beginning, so it’s essential to keep the rooting medium moist but not overly wet. It is essential to keep the cuttings protected from drying out at this phase. If everything goes well, first cuttings start swelling the buds on the shoots they initially grew in the beginning. The new growth indicates that the cuttings made their first roots. Those roots make it possible for them to acquire more nutrients and continue with growth. When their second growth phase is completed after the growth of new leaves and shoots ceases, it’s time to plant them into separate pots. Some of the cuttings never make it and I wouldn’t wait too long, before I transplant the ones that had rooted successfully.

Blueberry propagation nice

have you tried taking cuttings already? It works way faster than growing from seeds.

oh I LOVE BLUEBERRIES! good luck🍀
