Prime's Clippings April 2018

Enjoying a Great Spring 

April began with a beautiful spring morning followed by a cold front that dropped us into the low 40s Monday morning. For folks like me that planted tomatoes and peppers this weekend I hope you remembered to cover them!

The heavy rains have got us off to a good start on watering in new plants but that also means the weeds are happy. Remember that most of the weeds you see now will burn out as it warms up, and broadleaf weed killers will control a lot of our problems. But most weed controls do not work overnight as advertisers like to claim. Weed management depends on many factors—temperature, growth stage of plant, etc, and is an on-going process.

Trees are budding and some are making messes dropping their leaves (live oaks), seeds or tassels, spring flowering shrubs are in bloom, and bugs of every denomination are starting to bug everyone. No complaints here though, this is a magical time of year in north Texas.

April is absolutely the busiest month of the year for gardening, so please be patient with us if we can’t always get right to you. We promise to do our best!

Shades of Purple 

You can’t help but notice some of the beautiful lavenders and blues that make their appearance in the spring. Here are a few of my favorites.

Texas Mountain Laurel Sophora secundiflora 

Native to the hill country, this small tree will grow here if planted with good drainage and a little northern protection. The blooms are sweetly fragrant.

Purple oxalis Oxalis triangularis 

This purple shamrock is a wonderful border for shade gardens.

Chinese wisteria 

If you have the right space and time for an aggressive vine, the reward is a beautiful show in spring.

Iris

So many varieties, so little time to identify each one that a friend has given you. Better to just enjoy. 

Time for Summer Color 

Start making plans now for your summer color. The petunias we recently planted will make a for a big show through May. If you are a petunia person you will need to swap them out for hot weather plants like lantana or periwinkles in early June. But if you just have pansies or nothing at all in your beds then you can start planting many summer flowers now.

So many choices, but low maintenance plants that are not finicky are a big factor for most of us. Few people have the time or inclination to constantly check and treat for insects or diseases, and we need plants that can outlast a long summer season with extreme temperatures. So with this demanding criteria, here are some proven winners.

Full sun or afternoon sun areas: 

Lantana is hands-down the toughest choice for high heat, and the absolute best choice for dryer beds. Some folks think lantana can get a little unruly, but there are new compact dwarf varieties that really perform and grow only to about 12 inches.

For big accents use purple fountain grass, esperanza, sun coleus, or tropical hibiscus.

Scaevola is a great trailing plant in lavender or white, and Blackfoot daisy is a fragrant mounding/trailing plant—both great for rock walls, containers or borders.

Pentas are another heat lover with few problems

Periwinkles love the heat but cannot be planted here until about mid-may due to pythium and rhizoctonia root rot when nights are cool or it is too wet. Dwarf zinnias can have similar issues if planted too early.

Sweet potato vines are another great accent as long as you have the space for them or the time to periodically cut them back, and artemesias such as Dusty Miller or Powis Castle provide silvery foliage. Sunpatiens are a sun tolerant variety of impatiens and perform well with adequate water, but are usually quite a bit pricier.

Other choices for sun include Angelonia, Torenia, Salvia—both perennial and annual types, Blue Daze, Moss Rose, and Purslane. Bronze begonias tolerate sun or shade so are great for those places that go in and out of the sun, but they struggle with uneven moisture, and with twice a week water restrictions it can be hard to keep them looking good in July-August.

Shade areas: 

In the shade, caladiums and begonias are king with impatiens close behind.

Impatiens need a little light to look good all summer. In heavy shade they tend to get leggy in July-August.

Caladiums also need consistent water. You can also use foliage plants like shade coleus, Japanese painted fern, alternanthera, or lamium.

And Dragon wing begonias rule!
