It's April! It's Spring!

It's National Gardening Month..

What to do in YOUR garden ...

Spring is truly here and it really is the right time to sow, plant, and transplant. The growing season is upon us and it is time to take advantage of it to enhance the beauty of your entryway and back yard. 


Plant flowers in a bright container: For color all season long plant flowers such as geraniums, nemesia, bacopa, petunia and million bells. We have recently had a delivery of new containers of all different sizes and colors. Try blue flowers in an orange container. Gorgeous! Or red geraniums in a blue container... very Mykonos!  Or for a July 4th celebration plant red geraniums, white bacopa and blue lobelia...


Plant tomatoes:  There is nothing like the taste of a ripe, home grown tomato and we have many different varieties of tomato plants at Deep Roots Garden Center, including delicious heirloom tomatoes of all colors, shapes and sizes. Plant them in full sun in the ground or in a large container. Be sure to add a generous quantity of organic fertilizer to the soil before you plant.


Plant Bedding plants: Replace fading cool-season annuals with heat lovers such as celosia, dahlias, marigolds, petunias, salvia, verbena, and vinca. Try starting cosmos, sunflower, and zinnia from seed, even if you're a novice gardener. They're all super-easy, make good cut flowers, and attract the beneficial insects you want in the garden.


Rose companions: Planting perennials in your rose beds adds complementary textures, forms, and colors, and provides interest when roses are not in bloom. According to Wen Wang, rosarian at Descanso Gardens in Flintridge, good choices include catmint, cranesbill, feverfew, French lavender, lamb's ear, Shasta daisies, snow-in-summer, and veronica. We also like bearded iris, scented geraniums, and 'Indigo Spires' salvia.


Vegetables: Coastal gardeners (in Sunset climate zones 21-24) can continue to plant quick-maturing, cool-season crops, including chard, leaf lettuces, radishes, and spinach. Inland (zones 18-21), switch to warm-season crops such as beans, corn, cucumber, eggplant, melons, peppers, summer and winter squash, and tomatoes. 


Start an herb garden: Plant chives, parsley, rosemary, sage, tarragon, thyme, and my all time favorite herb - Winter Savory. Many varieties can also be grown successfully from seed, such as arugula, chervil, cilantro, and, of course, dill. 


Divide cymbidiums: If pots are too packed with bulbs, some brown and leafless, it's time to repot. Knock the root mass out of the pot and separate it into clumps by hand or with pruning shears. Keep at least three healthy bulbs with foliage; re-pot those in fresh potting medium designed for orchids.


Fertilize: Feed trees, shrubs, groundcover, perennials, and other permanent plants. Using an organic fertilizer like Dr. Earth will replenish micro-organisms in the soil as well as feed the plants. Try using a fertilizer containing iron on all plants, not just the chlorotic ones. 


Combat powdery mildew: Warm days and cool nights are ideal conditions for powdery mildew. To treat it, spray foliage with Serenade Fungicide or Neem Oil.


Manage aphids: Keep the aphid population in control by dislodging the pests from plant foliage with a strong blast of water from a hose.  If they keep coming back spray with Bayer's Rose and Flower insecticide, or an organic alternative Dr. Earth's Home & Garden insect spray. If you do not want to use pesticides try a carton of Lady Bugs from our Bug Fridge.


Manage snails:Search for snails on strappy-leafed plants such as agapanthus, liriope and daylilies, then hand-harvest and dispose. Or trap by allowing them to collect on the underside of a slightly elevated board. 

Not your idea of a good time?  Try sprinkling pet-safe Sluggo all around your garden beds instead."


Grow perennials bees love: Lure bees to pollinate your fruits and veggies. The following bee magnets need only moderate water: Agastache, ‘Mönch’ aster, catmint, germander, lavender, rudbeckia, and Salvia chamaedryoides. See for more choices. No need to be afraid of bees. They are only interested in flowers. If they investigate you closely it is because you are wearing a bright color or a sweet perfume. Stand still until the bee realizes her mistake and she will fly away. Wasps and yellow jackets, however, are another matter.....


Sow or Grow annuals: Cosmos, sunflowers, and zinnias are quintessential summer flowers ― neither fussy nor thirsty ― and are great if you’re new to growing seeds. They also draw bees and beneficial insects. Other non-thirsty annuals include celosia, marigold, portulaca, sanvitalia, and sweet alyssum.    


Bugs have arrived:  Our "bug fridge" is full of beneficial insects... ladybugs, lacewings, beneficial nemetodes, praying Mantids, and earthworms. Are you having a problem with raccoons, skunks or possums digging up your lawn? They are probably looking for fat white grubs to eat. Getting rid of the grubs will get rid of the problem. Microscopic beneficial nemetodes attack and kill these grubs as well as over 230 soil borne pests. Easy to apply and extremely effective, come and raid our fridge if pests start raiding your garden.

The Ultimate Potting Soil

We have said this before but it doesn't hurt to repeat it... with potting soil you get what you pay for. Potting soils vary enormously in organic content, nutrtional value and water holding abilities. 


The ultimate potting soil is Fox Farm's Ocean Forest Potting Soil. It is a little bit more expensive than other potting soils but plants planted in this soil grow bigger, healthier, greener and have more flowers and fruit than plants grown in Brand X. It is also safe for organic vegetable growing as there is no sewage sludge in it as you may find in inferior products.


Fox Farms is the ultimate potting soil—everything your plants need, in one bag. Ocean Forest® is a powerhouse blend of premium earthworm castings, bat guano, and Pacific Northwest sea-going fish and crab meal. Composted forest humus, sandy loam, and sphagnum peat moss give Ocean Forest® its light, aerated texture. Start with Ocean Forest® and watch your plants come alive!

Perfect for containers and ready to use right out of the bag. Ocean Forest® is pH adjusted at 6.3 to 6.8 to allow for optimum fertilizer uptake. There’s no immediate need for additional fertilizers, though in time, you will need to return to a regular feeding schedule.

How Much Potting Soil will I need....?

Now that the growing season is full on, it's time to repot your potted plants, or move them into bigger pots. When you buy a container, the sizes usually represent the diameter of the pot, e.g: 8", 10" etc. However a bag of potting soil is measured in quarts or cubic ft. How do you work out how much potting soil you will need to buy to fill a pot? This is difficult to say exactly because different potting  soils have different densities. For example, Fox Farms potting soil is more dense than LGM potting soil, therefore will fill more pots. On-site experiments were inconclusive but here is a table that gives approximate amounts of potting soil for different size pots. ALWAYS buy more than you need. If you have any unopened bags left you can return them.



  Pot Size and # of pots filled
Size of Bag    8 inch   10 inch   12 inch   14 inch
1 cu ft      9      4½      3      2
1.5 cu ft     13      5      4     2½
2 cu ft.     17      8      6     4½
Soil Volume   of pot (quarts)     3.6    6.9    10.7    15.3
                 Window Box Size  
Size of Bag    24 inch    30 inch   36 inch    
1 cu ft      2¾      2     1½  
1.5 cu ft      3½      2½     2  
2 cu ft.      5½      4     3¼  
Soil Volume of pot (quarts)    11.7    15.6    19.7

 Flowers for Fragrance

Summer is almost here...The days are getting longer and life will be moving outdoors.


Now is the time to plant scented shrubs and vines or even a complete scented garden in your outdoor room.


The supply of scented plants is excellent this time of year and if planted now, you will have a good chance of plentiful fragrant blooms all summer.


Almost all scented plants can also be grown in containers so they make a great addition to patios and balconies.


Most of them require good drainage and slightly acidic soil.


Here is a list of the best summer scents:



Butterfly Bush



Night Blooming Jasmine



Citrus Trees




Star Jasmine

Viola Odorato




Scented geraniums


Pets Beware!

We often are asked which plants are poisonous to cats, dogs and children. After several hours of careful research we have concluded that just about every plants is poisonous to cats, dogs and kids one way or another. We have created an extensive list of these plants on our web site: 


Very, very few plants (if any) sold to the public are deadly. Many on the list, if ingested, cause nausea or other slight reactions. Some will sting or cause a rash if touched. Best to train your critters not to eat plants except vegetables! For the final say on which plants are poisonous ALWAYS check with your vet.


BTW It is quite normal for pets to eat grass...
