Small Ornamental Annuals

qBrian in Alexandria asked, “I am looking for some types of small ornamental annuals. I have a spot that gets morning sun and afternoon shade. Can you suggest some options?”

aAny type of Impatiens would work. They come in colors of pink, purple, yellow, white, oranges and reds. Also Torenia, which are mostly shades of purple, Caladiums which are speckled greens, reds, pinks and white. There is also Begonia’s that are the green leaf variety which come in pinks, reds and whites. There are several others and the best thing to do is come to the garden center in mid April when they arrive.

Hope this helps!

Del Ray Lawn and Bush Tips

qJoe in Del Ray asked “My wife and I moved to Del Ray last summer and were too busy putting the inside of the house together that we didn’t do anything for the outside. Starting with the basics, what is the best type of grass to grow in this neighborhood? How often should we water the lawn? The previous owner left us two rose bushes. What’s the best way to care for them?”

aThe most common grass that is grown in this area is tall fescue. It’s adaptable to sun and shade and holds up well during a drought. However, if you have a very sunny location, I would also recommend overseeding with Kentucky Blue grass seed. It will develop a much thicker and greener lawn and is perennial. Perennial means that if it dries out during a drought, it will go dormant and turn brown, but will come back again with watering and fertilizing. If fescue dries out, it will die. Therefore it’s a good idea to mix the two. During the summer you should water every day for 10-15 minutes and keep your mower set to it’s highest point so you don’t strip the grass. Keeping it a little taller shades the root system. Right now is also a good time to put down a pre-emergent weed killer. We sell a product called “Concern” that is also organic.

As far as the roses, it depends on what type they are in order to answer your question. Whether they are shrub, climbers, or hybrid tea for example. If they look very leggy, it’s probably a good idea to give them a hair cut and fertilize with a slow release fertilizer.

Happy gardening in Del Ray!

Chervil is a difficult herb to find — seeds or plants. Do you carry it? Thanks!

Chervil is a unique herb, however not one that we currently stock.
You can find it online at Burpee as well as Seeds of Change (if you prefer

What do you recommend for a shady garden under a giant Del Ray white oak?

Comment by Tom — October 14, 2009 @ 11:44 am

The soil under a mature oak is probably filled with surface roots from the oak. We really don’t recommend planting anything under mature trees because the surface roots of the tree are it’s main feeder roots. If you do plant, try to come out as far as possible from the trunk. Always add soil amendments to build the soil up slightly, but no more than a few inches. Water will always be an issue as well because the tree will soak it up first. Droought tolerant perennials such as Epidemium, Tiarella, Convallaria, Hosta and Heuchera’s should work.

Hi — I’m tyring to get some impatiens Snow n Ice. The US grower is DS Cole, the brokers they use are:
Ball Seed Co., Fred C.Gloeckner Co., Harris Seeds., McHutchisons, Henry Michell Co., Park Seed Co. and S&G Flowers. Cole referred me to the brokers, but they only sell thru garden centers. I’m wondering if you have a realtionship with any of these brokers and could possibly get me some plants. Cole says they will have several flats ready next week. Thank you
