Healthy Plants. Q&A from Mr Booster: Fertilizing Mango trees in Winter

Q: I'm living in Maryland growing zone 7A and would like some info on when to fertilize my potted mango trees. I ordered your Sunshine Mango Tango 2-2-4. All your mango trees are in pots.

A: You can start using this fertilizer right away, any time of the year, and every time you water your plants.
Sunshine Mango Tango, as well as other Sunshine boosters, is an amino-acid based liquid fertilizer that is scientifically developed for daily plant needs in all necessary nutrients. This means, you may use this fertilizer with every watering, including winter period.
Traditional fertilizers (both granulated and soluble, EDTA-chelated) can only be used during hot months while plants grow actively, and must be limited or not used at all during cooler months, to avoid nutrient lock up in soil (which basically means "building up unused elements"). With Liquid Sunshine Boosters, it is safe to add them every time you water your tree.
During cooler weather and when plant metabolism slows down, a tree will consume less water (as well as food), and you will automatically reduce watering, to keep over-wintering plants on a dry side. This means, less fertilizer too. This allows you to control elements intake naturally, like you control water amount just as much as the plant needs.

Triple Sec Mango

By Onika Amell, tropical plant specialist

Q: I live in Mesa, Arizona. I am considering purchasing two of you Triple Sec Mango trees. Can you please give me some information on this variety and how to grow it successfully here in hot and arid Arizona, if at all?

A: Triple Sec Mango is a new name for the superior variety Seacrest. The aroma of this fruit resembles Triple Sec - an orange liqueur. It's a juicy, mid-season variety that has good disease resistance.
Mango has pretty good heat and drought tolerance. It loves sun, but there are a lot of factors to consider when growing Mango in your area.
Check your soil. Soil quality is always first and foremost: when you live in an area of Arizona with hardpan (extremely compacted desert soil) or caliche (layers of soil cemented by calcium carbonate) you will have to learn how to deal with such soil types. Amend the soil as needed.
The best time to plant is spring or fall to give your Mango a chance to get established before the really intense Summer heat starts. Alternatively, protect the tree with a shade cloth. Tender, new growth will not stand a chance unprotected, especially newly planted and/or young trees.
Mangoes are tropical and sensitive to frost and freeze damage. Young trees especially will also need winter protection when temperatures go near or below freezing. Always plant trees in a location where they will be protected from cold wind. Consider staking your newly planted Mango trees for the first year. It's never a bad idea to even stake during periods of high winds.
Make sure your planting site has very good drainage. Always use a good quality mulch around your tree as it helps to trap moisture, keeping the ground and the roots beneath it cool. Keep mulch a couple of inches from the trunk of the tree. Avoid a location that gets full day sun. Morning sun, afternoon shade is ideal. Give regular watering until the tree is established. Once established, water only when the soil feels dry.
Fertilizer with a Mango-Food. A foliar spray of micronutrient solution is always recommended during the active growing period. Use plant stimulants and microelements to improve cold hardiness and vigor.

Growing mango tree in California

Q: I just ordered a mango tree. I live in Southern California and was wondering if you have any tips on how to acclimate the mango to our climate. I know it is coming from hot and humid Florida to hot and dry Southern California and don't want to kill it because of the differences in climate.

A: Mangos in fact prefer dry conditions rather then humid. It may be perfect conditions for a mango tree at your place. Plant your tree in a pot size of the root ball; give it ample water and then let the soil surface slightly dry before watering again. Keep the plant in bright shade and gradually move into full sun. Once the tree is recovered from shipping stress, you may plant it in the ground and make sure to protect from freezing temperatures in winter. Use Mango Food for quick establishing and better fruit production. More to read:
