Welcome to Homegrown Harvest Live Q&A Thursday! Every Thursday at 2pm, Mark and Xine answer questions related to gardening or sustainable living from followers during their live podcast aired on Instagram @homegrown_harvest
Daphne from Connecticut – Zone 6b asks “How do you take care of a Ranunculus Mache Pastel flowers? Am I supposed to prune this thing, how often do I water it, do I planted into the ground?
Tecolote Ranunculus – incredibly bold colors, make for great cut flowers with extended vase life. They need bright sun, rich soil and light watering – if planted needs to be in well drained area
In zones 8 and warmer they can be planted in the fall. In zone 7 and colder, plant bulbs in the springtime or plant in containers.
When choosing a container, you always need to be sure to pick the right size container for the plant you are growing. For ranunculus bulbs leave 3- 4 inches between the bulbs, and plant 2” deep in the container. Once there is no threat of a frost put the container outside in a sunny spot.
Ranunculus are perennials in warm climates zone 8 and higher; whereas zone 7 and lower the plant acts as an annual, so you have to start over the following spring with new bulbs
As a cut flower they can last up to 10 days!
Kristin from Connecticut – zone 6 writes in that she mulches her garden beds and the property slopes downward. What is the best mulch that will stay put in heavy rains?
All mulches will float and wash away in a flood but some stay put better than others. Pine straw is highly recommended since the needles entwine and it help it stay put better than wood chips or bark nuggets which float off onto the lawn. Shredded bark or wood is good, something with pieces that tangle and hold onto one another.
Ideally if you can edge your garden with something high enough to hold the mulch in place – stones, wood that helps. You can also use other plants plie monkey grass of hostas or a type of ground cover as a protective border to keep the mulch in. Trenching a 3- 4” deep moat around the bed will help geep the mulch from floating off.
The Idaho Dept of Environmental Quality recommends that mulches that as meant to last longer than 3 months on slopes steeper than 50% – you use straw or hay held in place by netting. And they don’t recommend using wood chips if the slope is steeper than 6%, because they wash away.
Kristin, I would use pine straw and depending on your slope possibly throw some netting down and tack it down with landscape fabric stakes.
Carolyn from Connecticut asks what is the best time to prune ones rose bushes?
The trick about pruning is timing since if you do it too soon, you run the risk of having new growth stimulated during a warm spell which could be killed later by a freeze. Prune too late and your plant misses the spring bloom. So how do you know?
One trick is if you live in an area where there are forsythias -wait until the forsythias are in bloom. Forsythias only bloom when the soil temperature is 55° of warmer in the first 6 inches of soil depth – this is a natural indicator that it’s the perfect time to prune your roses. If you don’t live in an area where there are forsythias – early spring after the last frost in colder climates, when they start to bud or leaf out. If you have a soil thermometer again you are looking for 55°.
