Gardener's HQ Guide to Growing Rhus Glabra<\/em><\/strong><\/span><\/h2>\n\n\n\n

Rhus glabra<\/em> is a very common plant in the lower 48 states, where it can often be found growing in the prairies, in fields, and alongside roads.<\/p>\n\n\n\n

If you would like to grow this attractive plant on your property then it can easily be grown from seeds.<\/p>\n\n\n\n

<\/div><\/p>\n\n\n\n

Finding and Preparing Seeds<\/span><\/h3>\n\n\n\n

You can purchase Rhus glabra<\/em> seeds online or you can gather from the plants themselves.<\/p>\n\n\n\n

To gather seeds from the wild, you will need to collect the bright red berry heads in the fall (autumn).<\/p>\n\n\n\n

Once harvested, place them on old newspaper and let them dry out.<\/p>\n\n\n\n

Make sure you place them in a warm spot that is free from moisture.<\/p>\n\n\n\n

Separating the Seeds from the Berries<\/span><\/p>\n\n\n\n

In the next step, you will need to separate the seeds from the berries.<\/p>\n\n\n\n

Place them in a plastic bag and hit them against a hard surface. This will make it easy to extract the seeds from the berries.<\/p>\n\n\n\n

Cleaning Seeds<\/span><\/p>\n\n\n\n

Next, place the seeds in container of water.<\/p>\n\n\n\n

Allow them to soak and then remove the ones that float, as these won't be viable for planting.<\/p>\n\n\n\n

Soak Overnight<\/span><\/p>\n\n\n\n

After picking out the best possible seeds, return them to a container of warm water and allow them to soak for 12 hours or overnight.<\/p>\n\n\n\n

In the morning, check the seeds to make sure they have swelled up.<\/p>\n\n\n\n

Soil Type<\/span><\/p>\n\n\n\n

When it comes to soil type, Rhus glabra<\/em> is not very picky.<\/p>\n\n\n\n

It will grow in many different soil types but you should avoid planting it in areas that are poorly drained.<\/p>\n\n\n\n

Planting the Seeds<\/span><\/p>\n\n\n\n

You will want to start your Rhus glabra<\/em> seeds in a large pot. This will help them build a strong root system before they are transplanted directly in the garden.<\/p>\n\n\n\n

When planting seeds, sow them on top of the soil and cover them with a thin layer of potting soil.<\/p>\n\n\n\n

Water them and then place them in a warm area of the home.<\/p>\n\n\n\n

Germination can take a few months so make sure you keep an eye on them.<\/p>\n\n\n\n

If the soil becomes dried out, water them lightly.<\/p>\n\n\n\n

Transplanting to The Garden<\/span><\/p>\n\n\n\n

When your Rhus glabra<\/em> plants are growing strong and become too big for the pots, it is time to transplant them in the garden.<\/p>\n\n\n\n

Pick an area of the garden that has lots of space because these plants will grow very big compared to other plants. They well require a soil that has good drainage.<\/p>\n\n\n\n

During planting, you will need to dig a hole large enough to accommodate the plant and use lots of rich mulch to help them get started.<\/p>\n\n\n\n

Caring for Rhus Glabra<\/em><\/span><\/p>\n\n\n\n

Once you have a well-established group of Rhus glabra<\/em> plants in your garden, they require little care.<\/p>\n\n\n\n

During very hot summer months, you may need to water them but keep in mind, they like well-drained soil. Also, you may need to prune them from time to time because they may become overgrown if not kept in check.<\/p>\n\n\n\n

Warning: When planting Rhus glabra<\/em> in the garden, make sure you are careful where you plant it.<\/p>\n\n\n\n

This plant species can be invasive and can take over large areas of land if not properly controlled.<\/p>\n\n\n\n
