In Your Garden

February in your Southern California landscape is the beginning of new growth. It’s also a month of transition. Spring is looming but winter is still with us. Although frosts are possible they’re improbable after February 1st. Be aware of the weather and plan your garden activities accordingly. Don’t prune back flowering perennials too soon and put them at risk to cold damage.

Take this time instead to plan this year’s changes. Review your notes of what did and didn’t do well last year. A successful garden depends on planning and attention. If you have a busy schedule, use low maintenance plantings to create a ‘well tended’ garden with little effort after it’s established. Consider introducing a new plant into your program; perennials and vegetables both. There are a lot of new varieties available at Briggs. Try one just for the fun of it and see how it does.

Color: Filling in blank spots with cool weather annuals such as dianthus, Iceland poppies, pansies, stock, primula, snapdragons and calendulas is a great way to make an impact fast. Clear leaf trash from winter storms out of the beds and punch in a little spring color for instant gratification.

Fruits & Vegetables: There’s still time to plant bare root fruit trees, grapes and berries before they begin to leaf out. Make sure it’s done early in the month. If you haven’t already done it, prune your fruit bearing trees. Midmonth is the time to apply the final spray application for pests on your deciduous fruit trees. Fertilize deciduous fruit trees 2 to 3 weeks before they flower. Along the coast, Citrus and Avocado’s can be fertilized this month. Inland, wait until next month.

Cool weather vegetables like lettuce, carrots, broccoli, celery, white potatoes, peas and radishes can be planted now. At the beginning of the month, the soil’s not warm enough to plant warmer crops like tomatoes and peppers. Wait until the soil temperature reaches about 60 degrees.

Roses & Flowers: Azaleas and Camellias are in full bloom. Plant those now using an acidic soil mix which will help them thrive. However, you want to feed once they’ve stopped blooming. Prune hydrangea and feed with a high nitrogen fertilizer. If you want blue blossoms, apply Hydra blue (aluminum sulfate) or a similar product now for blue flowers next year. Dormant roses should have been pruned by now and you may be seeing some new growth. Fertilize lightly toward the end of the month.

Also: Applying a pre-emergent weed killer will save you time later in the season. Do not apply in areas where you plan to sow seeds for vegetables or flowers. Pull weeds while they’re small before they have a chance to spread seeds around your garden.

Finish heavy pruning of dormant trees before they bud out.

It’s not too late to plant summer blooming bulbs like Canna, Gladiola, Lilies, Tuberoses and tuberous Begonias. If you plant a couple of gladiolus each week through the end of next month, you should have continual blooms through the summer.

In January, your landscape is at its most dormant stage and there’s very little to do.  Aside from pruning and transplanting there’s not a lot going on.  With high moisture levels in the ground, be careful not to disturb the soil too much.   Overworking can result in compaction that may harm the soil structure.   Do go to your local nursery or garden center.  Azaleas, Camellias are blooming along with New Zealand Tea Trees (Leptospermum scoparium) and other plants.  Putting these in your garden will ensure that you have flowers in your garden when most flowering plants are in their dormant stage.

Color:   Fill in bare spots with cool weather annuals.  Pansies, Snapdragons, Iceland poppies and Kale are great additions to the garden along with Cyclamen, Primula and Begonias.  Keep leaf trash cleaned from the base of the plants.  Plant summer blooming bulbs; canna, dahlia, lilies, tuberose and tuberous begonias.

Fruits & Vegetables:  Plant bare-root fruit trees, grapes, berries and strawberries now.  Soak roots in water overnight before planting.  Continue to spray dormant fruit trees for pests, include trunk and soil around the base of the tree.  Prune established fruit trees to maintain a uniform shape.  Many cool weather vegetables are available.  Sow beet, carrot and radish seeds.

Roses & Flowers:  Clean leaf litter from around the base of plants to discourage snails & slugs.  Bait as necessary.  Prune roses before new growth begins.  Water roses thoroughly before pruning.  Other flowering shrubs should be pruned after the first bloom cycle.

Also:  Natives can also be pruned lightly now in order to maintain a uniform shape.  If rainfall isn’t heavy, water deeply.  The moisture they store now will help them through the hot summer months.

Bulbs with higher cold requirements need to be planted in cold soil.  If the weather is cool, between Christmas and New Years, plant then.  Otherwise wait until the soil temperature drops being sure to plant before January 10^th.

Protect tender plants from frost by covering them with a non-plastic material when frost threatens.  Keeping plantings well hydrated will help frost survival also.  A turgid plant will recover from frost better than a dry plant.  Should a frost damage your garden, don’t be tempted to prune off the damaged parts.  They’ll help protect the plant from further damage should another frost occur.  Trim these parts off later in the year when all risk of frost has past.

Plant and transplant Azaleas and Camellias.  Be sure to use a high acid planting mix to promote growth.

Lawn: Mow cool weather lawns weekly. Appling a pre-emergent weed killer now will save you time and money later in the year. Give your lawnmower a tune up. Change the oil and have the blade to your lawnmower sharpened or do it yourself.

Roses & Flowers: Clean leaf litter from around the base of plants to discourage snails & slugs. Bait as necessary. Prune roses before new growth begins. Water roses thoroughly before pruning. Other flowering shrubs should be pruned after the first bloom cycle.

Irrigation: Do a test run on your irrigation system to ensure that all lines are clear and emitters are working efficiently. Watch your system carefully. If it rains, turn the system off and save the water.

Also: Natives can also be pruned lightly now in order to maintain a uniform shape. If rainfall isn’t heavy, water deeply. The moisture they store now will help them through the hot summer months.

Cool temperature weather is the perfect time to prune evergreens

Fertilizing typical and drought-tolerant trees in the landscape requires a knack for applying in the right season, proper administration and for using the best product for the tree. Fertilizer is often misunderstood and misused. Fertilizer is not really direct food for trees, but instead, a boost to your trees providing the ingredients needed for photosynthesis and growth. Fertilizer should not only be used when minerals are lacking or absent in the soil but also to maintain a good chemical balance within the soil all year long. Your top ten, typical choice of standard trees for most landscapes range from King and Queen palms to Agonis, Magnolia and Lagerstromia varieties. Drought-tolerant trees can be fertilized much in the same way. These trees should be fertilized on a regular schedule, depending on the geography and status of the tree. Trees in areas that receive a lot of rain usually have a lot of natural nutrients in the soil and only require about one to two times a year of fertilizer application. However, in more arid areas, like the Southwest, you should fertilize up to three times a year to produce more nutrients in the soil and to keep the plant healthy in each season. The best times for fertilizing is in early spring, mid-year and in the fall. The early spring is a good time because tree roots are coming out of the dormant period and require a boost to be healthy as they are starting to grow. Mid-year is also important because trees are experiencing more heat, absorbing water faster because of the heat and therefore going through nutrients quicker. To put in fertilizer during this time gives the tree a boost and replenishes those nutrients lost. During the Fall, tree roots have cooled a bit but there isn’t as much rainfall as during winter months. Avoid fertilizing trees and shrubs stressed by drought during the summer months. If water is unavailable, do not fertilize at all because plants will be unable to absorb the nutrients.
