One of the most beautiful months in the southwest. (if the wind doesn’t blow) You can plant anything like tomato plants, fruit trees shade trees, evergreen shrubs, flowering shrubs, bulbs etc. It is also the month when gardening centers are usually fully supplied, at least in the southwest.
Now is the time to fertilize Bermuda or warm season herbs right now if you haven’t done so in late March. You can also fertilize your fern, rye or bluegrass lawns (cool season) if more than 6 weeks have passed since the last time you fertilized. 16-8-8 with iron, zinc and sulfur works well if you don’t have problems with weeds. This can be used in both hot and cool seasons at this time of year.
If you have oleander, now is the time to reduce any winter-damaged leaves or stems that may have suffered from the cold. Cut the oleander if you want it to appear full and thick or you can selectively prune the branches to give it a more open and airy appearance. You can also prune them in multi-trunk trees, which look quite picturesque when ripe.
Lantana plants may have just come out of their dormancy period at this time. It is best to take out any mulch that may be around the base of the crown, to allow the sun to warm the ground and allow it to “wake up” from its winter sleep. Do not be fooled by these plants, they may seem dead, but 9 times out of 10 they are only dormant. They need some heat to start growing. Be patient!
Roses could still be available right now and use well to be planted right now. For existing roses, fertilization is the key. I recommend a water soluble fertilizer with an analysis of 20-20-20 other weeks, for healthy foliage and multiple blooms.
In addition to this, use a soil acidifier such as Ironite or organic chelated iron. These products help maintain dark green foliage and give flowers more vibrant colors.
Now there is a new Bayer product that contains a fertilizer, a disease prevention product (mold powder, rust, black spot) and insecticide all in one. It is in liquid form and can be used every six weeks during the growing season. If you apply it early enough, you may never have to spray roses

For existing roses, fertilization is the key. I recommend a water soluble fertilizer like Peters 20-20-20 every other week, for healthy foliage and multiple blooms. In addition to this, use a soil acidifier such as Ironite Tm or Grow More Tm organic chelated iron. These products help maintain dark green foliage and give flowers more vibrant colors.
