Just when we think it's finally Spring, Winter keeps wanting to bite back. Way late on my blog this month, mainly cause everything is just so behind season this year. Crazy thing is next week we have chances of hitting the low 40's, high 30's...so it's screwing up planting schedules.

April to do list (Zone 4a-6a) Each category is listed in order of activity from top of the list to be done in the early month to the end of the list to be done mid-late April.

Ornamentals:
-When buying bedding plants, choose compact, bushy plants that have not begun to flower.

-Study your landscape for gaps that could be nicely filled with bulbs. Mark these spots carefully and make a note to order bulbs next August.

-Enjoy, but do not disturb the many wildflowers blooming in the woodlands.

-When Crab Apples are in bloom hardy annuals may be transplanted outdoors.

-Fertilize established roses once new growth is 2 inches long. Use a balanced formulation. Begin spraying to control black spot disease.

-Examine shrubs for winter injury. Prune all dead and weakened wood.

-Shrubs and trees best planted or transplanted in spring rather than fall, include the Butterfly Bush, Dogwood, Rose of Sharon, Black Gum, Vitex, Red Buds, Magnolias, Tulip Poplar, Birch, Ginkgo, Hawthorn and most Oaks.

-Winter mulches should be removed from Roses. Complete pruning promptly. Remove only dead wood from climbers at this time. Cultivate lightly, working in some compost or other organic matter.

-Break off rims from peat pots when transplanting seedlings, otherwise they can act as a wick to draw moisture away from the roots.

-Transplant Virgina Bluebells (Mertensia virginica) after bloom before the foliage disappears.

-Do not prune boxwoods before April 15th

-Evergreen and deciduous hedges may be sheared after mid-April. Prune the top narrower than the base so sunlight will reach the lower limbs.

-Groundcovers can be mowed to remove winter burn and tidy plants up. Raise mowers to their highest settings. Fertilize and water to encourage rapid regrowth.

-Balloon flower (Platycodon), Hardy Hibiscus, Gasplant (Dictamus albus) and some lilies are slow starters in the spring garden. Cultivate carefully to avoid injury to these tardy growers.

-Apply controls for holly leaf miner when the new leaves are just beginning to grow.

-Easter lilies past blooming can be planted outdoors. Set the bulb 3 inches deeper than they grew in the pot. Mulch well if frost occurs.

-Prune spring flowering ornamentals after they finish blooming

-Begin planting out summer bulbs such as Caladiums, Gladiolus, Acidanthera at 2 week intervals

Lawns:
-Start mowing cool season grasses at recommended heights.

-Topdress low spots and finish over seeding thin or bare patches

-Aerate turf if thatch is heavy or if soil is compacted

-Apply crabgrass preventers as the Forsythia comes to the of it's bloom period. Do not apply to areas that will be seeded

Veggies:
-Finish transplanting Broccoli, Brussels Sprouts, Cabbage, and Cauliflower plants into the garden. High phosphorous fertilizers get transplants off to a quick start.

-Asparagus and Rhubarb harvest begins

-Finish sowing seeds of all cool season vegetables not yet planted

-Start Cucumber, Cantaloupe, Summer Squash, and Watermelon seeds indoors in peat pots

-Plastic films can be used to pre-heat the soil where warm season vegetables are to be grown.

-Plants started indoors should be hardened off outdoors in cold frames before being transplanted into the garden.

-Keep your hoe sharp! Don't allow weeds to get an early start in the garden.

-Flower stalks should be removed from Rhubarb plants if they develop.

-Handpick and destroy Asparagus beetles.

-Try an early sowing of warm season crops such as Green Beans, Summer Squash, Sweet Corn, New Zealand Spinach and Cucumber

-Thin out crowded seedling from early plantings of cool season crops such as Beets, Carrots, Lettuce, Onions, and Radish

-Sow seeds of Luffa and hard-shelled Gourds indoors in peat pots. Soak seeds overnight before planting.
-Begin setting out transplants of Tomatoes, Eggplants, Peppers and Sweet Potatoes

-Begin planting Lima Beans, Cucumbers, Melons, Okra and Watermelon

Fruits:
-A white interior latex paint may be brushed on the trunks of newly planted fruit trees to prevent sunburn. This will gradually weather in time.

-Prune Peaches and Nectarines now.

-Leaf rollers are active on Apple trees. Control as needed.

-Stink bugs and tarnished plant bugs become active on peaches.

-Wooden clothespins make useful spreaders for training young limbs. Place pins between the trunk and branch to force limbs outward at a 60 degree angle from the trunk.

-Plant bare-root or potted fruits as soon as the soil can be worked

-Remove tree wraps from fruit trees now.

-Protect bees and other pollinating insects. Do not spray insecticides on fruit trees that are blooming.

-Destroy or prune off webs of Eastern Tent Caterpillars. B.T. (Dipel) is a safe biological spray.

-Orange, jelly like galls on Cedar trees spread rust diseases to Apples, Crabapples and Hawthorns. Handpick these before they open or spray.

-Begin sprays for fire-blight susceptible Apples and Pears using agricultural streptomycin.

-Spider mites and codling months become active on Apples.

Miscellaneous:
-Termites begin swarming. Termites can be distinguished from their thick waists and straight antennae. Ants have slender waists and elbowed antennae.

-Look for Morel Mushrooms when lilacs bloom and the forest floor turns green.

-Mount a rain gauge on a post near the garden to keep track of precipitation so you can tell when to water. Most gardens need 1 inch of rain/water per week between April and September.

-Mole young are born in chambers deep underground. Best way to get rid of moles is taking away their food source (grub worms!). May take several seasons of applications to get this under control.

-Honeybees are swarming. If this is a problem for you, do not destroy, but instead contact a local Beekeeper to find a new home for these beneficial insects.

-Wasp and hornet queens begin nesting. Be careful not to get stung!

-Hummingbirds return from their winter home in Central America. Clean, stock up and get those feeders ready!

-Soaker hoses and drip irrigation systems help you save water and money. Consider adding these to your garden.

Happy Gardening!

Hey, some spring eh? We had a seriously late freeze here in N Texas. My cherry tomato had a bunch of little maters on it until the surprise freeze.

The roses are really happy though.

Did you know that the people who made Knock Out Roses have come up with some cool look-a-like rose cultivars?

I just got one called "Phloxy Baby" that is really pretty. Have not seen these before. Was kind of an impulse buy. Had to pull out a shrub that wasn't doing well to fit this one in.

New Shrub roses

Anyhow, you ever are in N Texas between Mid-April and June, give a holler if you want to see some of the cool rose places here. There is a three acre test garden in Farmers Branch that grows Earth Kind roses.
