Fertilize Landscape Trees
Use a balanced fertilizer and apply at 1/2 pound per inch of trunk diameter. Broadcast dry fertilizer around the drip line for best results. Do not fertilize trees that have insect infestations.
Plant Cool-Season Crops
Plant peas, sweet peas, broccoli, cabbage, and lettuce. Protect emerging seedlings with a layer of netting and some sort of snail barrier to deter hungry birds, as well as snails and slugs.
Begin Watering Indoor Cactus
If your indoor cactus plants have been on reduced rations for the winter months, it's almost time to start watering again. You should begin to see some new growth at the end of this month, and as soon as you do, start watering. You can fertilize lightly with fish emulsion to promote blooming.
Use Pot Feet to Prevent Root Rot
Set both indoor and outdoor container plants up on pot feet so their roots will remain up, out of any water standing in the saucer. Pot feet are available in many shapes, I recently saw some adorable elephants! They are usually made of clay and are an inexpensive way to keep your container plants healthy and happy. Use the pot feet inside the saucer to prevent root rot, and under the saucer to prevent damage to your carpets.
Fertilize Cymbidium Orchids
It looks like it's going to be a great year for cymbidium orchids. The mild, wet winter has brought on a flush of spikes. Fertilize with 1/2 strength 0-10-10 to keep your orchids looking great. If the foliage is bright yellow-green, your plants are getting the correct amount of light.
